We have:
- a set of patches that fixes various corner cases in mount and umount code (Xiubo Li). This has to do with choosing an MDS, distinguishing between laggy and down MDSes and parsing the server path. - inode initialization fixes (Jeff Layton). The one included here mostly concerns things like open_by_handle() and there is another one that will come through Al. - copy_file_range() now uses the new copy-from2 op (Luis Henriques). The existing copy-from op turned out to be infeasible for generic filesystem use; we disable the copy offload if OSDs don't support copy-from2. - a patch to link "rbd" and "block" devices together in sysfs (Hannes Reinecke) And a smattering of cleanups from Xiubo, Jeff and Chengguang. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAl47PUcTHGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi6LoCACmVli5N6bgnBE4sTixi/jz6aCCbk32 ZPlKiSesHnOGkY6KXHJT58JYy0paITBRik5ypdz06J8aCOtWyPLbn3uCemF9CYn2 g6dId2Lf5vGFrgSm4YSiqp9a86IZmYSDG41LbJD/IJWFDWdMWqNPMDqji6yaIO5O NJI5N0tk+VFXdV+JyjV9X/FnP1r1D2ReZzz21ZiqTJXSmE8YIkioLjkq36QTMMG7 Gm5qdlc1x2r4qfzA1g+OiWgRQCUMgkuYerFzus4mVbW4hrphsavH2DArbOwFmsXF 46hOq+1uGVVyZILLJfKNiktf1GExBF0icbSREJtmjUHbQvNR8BH0C+fV =vvIc -----END PGP SIGNATURE----- Merge tag 'ceph-for-5.6-rc1' of https://github.com/ceph/ceph-client Pull ceph fixes from Ilya Dryomov: - a set of patches that fixes various corner cases in mount and umount code (Xiubo Li).

Tracing updates:
- Added new "bootconfig".
Looks for a file appended to initrd to add boot config options.
This has been discussed thoroughly at Linux Plumbers.
Very useful for adding kprobes at bootup.
Only enabled if "bootconfig" is on the real kernel command line.
- Created dynamic event creation.
Merges common code between creating synthetic events and
kprobe events.
- Rename perf "ring_buffer" structure to "perf_buffer"
- Rename ftrace "ring_buffer" structure to "trace_buffer"
Had to rename existing "trace_buffer" to "array_buffer"
- Allow trace_printk() to work withing (some) tracing code.
- Sort of tracing configs to be a little better organized
- Fixed bug where ftrace_graph hash was not being protected properly
- Various other small fixes and clean ups

It adds votes for necessary power-domains for all Qualcomm TrustZone based remoteproc instances are held, fixes a bug related to remoteproc drivers registering before the core has been initialized and does clean up the Qualcomm modem remoteproc driver. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAl44/90bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3Fn08QAKenfTGFhCS/5nHpdCyL BXmT5uIVrZb2r9dfh572Mg5TQoEwELenx9ufE1qMubMpGLEEF2FyMLHrGCZL+bsT pl4vTFrd5zKNYpP6t1MbidUm0UE2RVaUAslUApcdD8JRUTRGZQzEmPBUK6H5ZuHZ 5YXyU+qCmZVPJdARJG3qwtspvoExwMF8iRk6+vQT5YEhkJZUhz0M6bDvUF5SptKb +zDXHjuKptS1cLWSb05lcFZBAj8hkF9gmOOFVTbzlfY5KNkks0GI0InCfWGqno4T 78q9mR4hxzqMvaa2M4nfZi2Kmvmp/upYKPnH+m9RwWETvN60g8CALOhjHDzCWW0T SuAGZ5GwzR9Upz9Iqy4idrwayromwZf3QSkta1XSUar+JG6/LlANX9n0b9ngL3FO stIxooglxRIRiVVM35nSwTttiaEOlht5xPBsTuCzZ1k3RCdpMKvWArTt+vi6ZQBq jP/dGiINuRGhEuO1Ky8YheVP3vsBEoKgH22nznfyE0FatnBQnQMo/kKaLCTrA9zm 5TRXG4Bef4gGAIiQEWSc6j7l7zs5OKlFHNcDjULFR9HMY5L6dcpeo0RFl0UCWNEx 4jRQeqMvi/jhCdJB74Uep4+zf/I23/qTd5LMfcEt0rEUtiLxpIAAS5FRqqb+BE84 iXeBPlkC5dTpwfrDSatzSgq0 =Ns9h -----END PGP SIGNATURE----- Merge tag 'rproc-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This adds support for the Mediatek MT8183 SCP, modem remoteproc on Qualcomm SC7180 platform, audio and sensor remoteprocs on Qualcomm MSM8998 and audio, compute, modem and sensor remoteprocs on Qualcomm SM8150.

lib: rework bitmap_parse()
bitmap_parse() is ineffective and full of opaque variables and opencoded parts. It leads to hard understanding and usage of it. This rework includes: - remove bitmap_shift_left() call from the cycle. Now it makes the complexity of the algorithm as O(nbits^2). In the suggested approach the input string is parsed in reverse direction, so no shifts needed; - relax requirement on a single comma and no white spaces between chunks. It is considered useful in scripting, and it aligns with bitmap_parselist(); - split bitmap_parse() to small readable helpers; - make an explicit calculation of the end of input line at the beginning, so users of the bitmap_parse() won't bother doing this.

lib/string: add strnchrnul()
Patch series "lib: rework bitmap_parse", v5.
Similarl to the recently revisited bitmap_parselist(), bitmap_parse() is
ineffective and overcomplicated. This series reworks it, aligns its
interface with bitmap_parselist() and makes it simpler to use.
The series also adds a test for the function and fixes usage of it in
cpumask_parse() according to the new design - drops the calculating of
length of an input string.
bitmap_parse() takes the array of numbers to be put into the map in the BE
order which is reversed to the natural LE order for bitmaps. For example,
to construct bitmap containing a bit on the position 42, we have to put a
line '400,0'. Current implementation reads chunk one by one from the
beginning ('400' before '0') and makes bitmap shift after each successful
parse. It makes the complexity of the whole process as O(n^2). We can do
it in reverse direction ('0' before '400') and avoid shifting, but it
requires reverse parsing helpers.
This patch (of 7):
New function works like strchrnul() with a length limited string.

Currently core /proc code uses "struct file_operations" for custom hooks, however, VFS doesn't directly call them. Every time VFS expands file_operations hook set, /proc code bloats for no reason. Introduce "struct proc_ops" which contains only those hooks which /proc allows to call into (open, release, read, write, ioctl, mmap, poll). It doesn't contain module pointer as well.

asm-generic/tlb: provide MMU_GATHER_TABLE_FREE
As described in the comment, the correct order for freeing pages is: 1) unhook page 2) TLB invalidate page 3) free page This order equally applies to page directories. Currently there are two correct options: - use tlb_remove_page(), when all page directores are full pages and there are no futher contraints placed by things like software walkers (HAVE_FAST_GUP). - use MMU_GATHER_RCU_TABLE_FREE and tlb_remove_table() when the architecture does not do IPI based TLB invalidate and has HAVE_FAST_GUP (or software TLB fill). This however leaves architectures that don't have page based directories but don't need RCU in a bind. For those, provide MMU_GATHER_TABLE_FREE, which provides the independent batching for directories without the additional RCU freeing.

asm-generic/tlb: avoid potential double flush
Aneesh reported that: tlb_flush_mmu() tlb_flush_mmu_tlbonly() tlb_flush() <-- #1 tlb_flush_mmu_free() tlb_table_flush() tlb_table_invalidate() tlb_flush_mmu_tlbonly() tlb_flush() <-- #2 does two TLBIs when tlb->fullmm, because __tlb_reset_range() will not clear tlb->end in that case. Observe that any caller to __tlb_adjust_range() also sets at least one of the tlb->freed_tables || tlb->cleared_p* bits, and those are unconditionally cleared by __tlb_reset_range(). Change the condition for actually issuing TLBI to having one of those bits set, as opposed to having tlb->end != 0.

mm/mmu_gather: invalidate TLB correctly on batch allocation failure and flush
Architectures for which we have hardware walkers of Linux page table should flush TLB on mmu gather batch allocation failures and batch flush. Some architectures like POWER supports multiple translation modes (hash and radix) and in the case of POWER only radix translation mode needs the above TLBI. This is because for hash translation mode kernel wants to avoid this extra flush since there are no hardware walkers of linux page table. With radix translation, the hardware also walks linux page table and with that, kernel needs to make sure to TLB invalidate page walk cache before page table pages are freed. More details in commit |

x86: mm: avoid allocating struct mm_struct on the stack
struct mm_struct is quite large (~1664 bytes) and so allocating on the stack may cause problems as the kernel stack size is small. Since ptdump_walk_pgd_level_core() was only allocating the structure so that it could modify the pgd argument we can instead introduce a pgd override in struct mm_walk and pass this down the call stack to where it is needed. Since the correct mm_struct is now being passed down, it is now also unnecessary to take the mmap_sem semaphore because ptdump_walk_pgd() will now take the semaphore on the real mm.

Rather than having to increment the 'depth' number by 1 in ptdump_hole(),
let's change the meaning of 'level' in note_page() since that makes the

Note that for x86, the level numbers were previously increased by 1 in

mm: pagewalk: add 'depth' parameter to pte_hole
The pte_hole() callback is called at multiple levels of the page tables. Code dumping the kernel page tables needs to know what at what depth the missing entry is. Add this is an extra parameter to pte_hole(). When the depth isn't know (e.g. processing a vma) then -1 is passed. The depth that is reported is the actual level where the entry is missing (ignoring any folding that is in place), i.e. any levels where PTRS_PER_P?D is set to 1 are ignored. Note that depth starts at 0 for a PGD so that PUD/PMD/PTE retain their natural numbers as levels 2/3/4.

mm: pagewalk: allow walking without vma
Since 48684a65b4e3: "mm: pagewalk: fix misbehavior of walk_page_range for vma(VM_PFNMAP)", page_table_walk() will report any kernel area as a hole, because it lacks a vma. This means each arch has re-implemented page table walking when needed, for example in the per-arch ptdump walker. Remove the requirement to have a vma in the generic code and add a new function walk_page_range_novma() which ignores the VMAs and simply walks the page tables.

mm: add generic p?d_leaf() macros
Patch series "Generic page walk and ptdump", v17. Many architectures current have a debugfs file for dumping the kernel page tables. Currently each architecture has to implement custom functions for this because the details of walking the page tables used by the kernel are different between architectures. This series extends the capabilities of walk_page_range() so that it can deal with the page tables of the kernel (which have no VMAs and can contain larger huge pages than exist for user space). A generic PTDUMP implementation is the implemented making use of the new functionality of walk_page_range() and finally arm64 and x86 are switch to using it, removing the custom table walkers. To enable a generic page table walker to walk the unusual mappings of the kernel we need to implement a set of functions which let us know when the walker has reached the leaf entry. After a suggestion from Will Deacon I've chosen the name p?d_leaf() as this (hopefully) describes the purpose (and is a new name so has no historic baggage). Some architectures have p?d_large macros but this is easily confused with "large pages". This series ends with a generic PTDUMP implemention for arm64 and x86. Mostly this is a clean up and there should be very little functional change. The exceptions are: * arm64 PTDUMP debugfs now displays pages which aren't present (patch 22). * arm64 has the ability to efficiently process KASAN pages (which previously only x86 implemented). This means that the combination of KASAN and DEBUG_WX is now useable. This patch (of 23): Exposing the pud/pgd levels of the page tables to walk_page_range() means we may come across the exotic large mappings that come with large areas of contiguous memory (such as the kernel's linear map). For architectures that don't provide all p?d_leaf() macros, provide generic do nothing default that are suitable where there cannot be leaf pages at that level. Futher patches will add implementations for individual architectures. The name p?d_leaf() is chosen to minimize the confusion with existing uses of "large" pages and "huge" pages which do not necessary mean that the entry is a leaf (for example it may be a set of contiguous entries that only take 1 TLB slot). For the purpose of walking the page tables we don't need to know how it will be represented in the TLB, but we do need to know for sure if it is a leaf of the tree.

mm: factor out next_present_section_nr()
Let's move it to the header and use the shorter variant from mm/page_alloc.c (the original one will also check "__highest_present_section_nr + 1", which is not necessary). While at it, make the section_nr in next_pfn() const. In next_pfn(), we now return section_nr_to_pfn(-1) instead of -1 once we exceed __highest_present_section_nr, which doesn't make a difference in the caller as it is big enough (>= all sane end_pfn).

mm/page_alloc.c: initialize memmap of unavailable memory directly
Let's make sure that all memory holes are actually marked PageReserved(),
that page_to_pfn() produces reliable results, and that these pages are not
detected as "mmap" pages due to the mapcount.
E.g., booting a x86-64 QEMU guest with 4160 MB:
[ 0.010585] Early memory node ranges
[ 0.010586] node 0: [mem 0x0000000000001000-0x000000000009efff]
[ 0.010588] node 0: [mem 0x0000000000100000-0x00000000bffdefff]
[ 0.010589] node 0: [mem 0x0000000100000000-0x0000000143ffffff]
max_pfn is 0x144000.
Before this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000000000800 16384 64 ___________M_______________________________ mmap
total 16384 64
After this change:
[root@localhost ~]# ./page-types -r -a 0x144000,
flags page-count MB symbolic-flags long-symbolic-flags
0x0000000100000000 16384 64 ___________________________r_______________ reserved
total 16384 64
IOW, especially the unavailable physical memory ("memory hole") in the
last section would not get properly marked PageReserved() and is indicated
to be "mmap" memory.
Drop the trace of that function from include/linux/mm.h - nobody else
needs it, and rename it accordingly.
Note: The fake zone/node might not be covered by the zone/node span. This
is not an urgent issue (for now, we had the same node/zone due to the
zeroing). We'll need a clean way to mark memory holes (e.g., using a page
type PageHole() if possible or a fake ZONE_INVALID) and eventually stop
marking these memory holes PageReserved().

eventfd: track eventfd_signal() recursion depth
eventfd use cases from aio and io_uring can deadlock due to circular or resursive calling, when eventfd_signal() tries to grab the waitqueue lock. On top of that, it's also possible to construct notification chains that are deep enough that we could blow the stack. Add a percpu counter that tracks the percpu recursion depth, warn if we exceed it. The counter is also exposed so that users of eventfd_signal() can do the right thing if it's non-zero in the context where it is called.

There are a few changes to the core framework this time around, in addition to
the normal collection of driver updates to support new SoCs, fix incorrect
data, and convert various drivers to clk_hw based APIs.
In the core, we allow clk_ops::init() to return an error code now so that we
can fail clk registration if the callback does something like fail to allocate
memory. We also add a new "terminate" clk_op so that things done in
clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now
when critical clks fail to enable and we support changing clk rates and
enable/disable state through debugfs when developers compile the kernel
themselves.
On the driver front, we get support for what seems like a lot of Qualcomm and
NXP SoCs given that those vendors dominate the diffstat. There are a couple new
drivers for Xilinx and Amlogic SoCs too. The updates are all small things like
fixing the way glitch free muxes switch parents, avoiding div-by-zero problems,
or fixing data like parent names. See the updates section below for more
details.
Finally, the "basic" clk types have been converted to support specifying
parents with clk_hw pointers. This work includes an overhaul of the fixed-rate
clk type to be more modern by using clk_hw APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180
- Graphics clk controller on qcom sc7180
- CPU PLLs for qcom msm8916
- Move qcom msm8974 gfx3d clk to RPM control
- Display port clk support on qcom sdm845 SoCs
- Global clk controller on qcom ipq6018
- Add a driver for BCLK of Freescale SAI cores
- Add cam, vpe and sgx clock support for TI dra7
- Add aess clock support for TI omap5

Pull clk updates from Stephen Boyd:
"There are a few changes to the core framework this time around, in
addition to the normal collection of driver updates to support new
SoCs, fix incorrect data, and convert various drivers to clk_hw based
APIs.
In the core, we allow clk_ops::init() to return an error code now so
that we can fail clk registration if the callback does something like
fail to allocate memory. We also add a new "terminate" clk_op so that
things done in clk_ops::init() can be undone, e.g. free memory. We
also spit out a warning now when critical clks fail to enable and we
support changing clk rates and enable/disable state through debugfs
when developers compile the kernel themselves.
On the driver front, we get support for what seems like a lot of
Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
There are a couple new drivers for Xilinx and Amlogic SoCs too. The
updates are all small things like fixing the way glitch free muxes
switch parents, avoiding div-by-zero problems, or fixing data like
parent names. See the updates section below for more details.
Finally, the "basic" clk types have been converted to support
specifying parents with clk_hw pointers. This work includes an
overhaul of the fixed-rate clk type to be more modern by using clk_hw
APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180
- Graphics clk controller on qcom sc7180
- CPU PLLs for qcom msm8916
- Move qcom msm8974 gfx3d clk to RPM control
- Display port clk support on qcom sdm845 SoCs
- Global clk controller on qcom ipq6018
- Add a driver for BCLK of Freescale SAI cores
- Add cam, vpe and sgx clock support for TI dra7
- Add aess clock support for TI omap5
- Enable clks for CPUfreq on Allwinner A64 SoCs
- Add Amlogic meson8b DDR clock controller

kgdb patches for 5.6-rc1
Everything for kgdb this time around is either simplifications or clean ups. In particular Douglas Anderson's modifications to the backtrace machine in the *last* dev cycle have enabled Doug to tidy up some MIPS specific backtrace code and stop sharing certain data structures across the kernel. Note that The MIPS folks were on Cc: for the MIPS patch and reacted positively (but without an explicit Acked-by). Doug also got rid of the implicit switching between tasks and register sets during some but not of kdb's backtrace actions (because the implicit switching was either confusing for users, pointless or both). Finally there is a coverity fix and patch to replace open coded console traversal with the proper helper function.

platform/chrome: cros_ec: Match implementation with headers
The 'cros_ec' core driver is the common interface for the cros_ec transport drivers to do the shared operations to register, unregister, suspend, resume and handle_event. The interface is provided by including the header 'include/linux/platform_data/cros_ec_proto.h', however, instead of have the implementation of these functions in cros_ec_proto.c, it is in 'cros_ec.c', which is a different kernel module. Apart from being a bad practice, this can induce confusions allowing the users of the cros_ec protocol to call these functions. The register, unregister, suspend, resume and handle_event functions *should* only be called by the different transport drivers (i2c, spi, lpc, etc.), so make this a bit less confusing by moving these functions from the public in-kernel space to a private include in platform/chrome, and then, the interface for cros_ec module and for the cros_ec_proto module is clean.
