powerpc/rtas: use correct function name for resetting TCE tables
The PAPR spec spells the function name as
"ibm,reset-pe-dma-windows"
but in practice firmware uses the singular form:
"ibm,reset-pe-dma-window"
in the device tree. Since we have the wrong spelling in the RTAS
function table, reverse lookups (token -> name) fail and warn:
unexpected failed lookup for token 86

KVM: PPC: Book3S HV: Fix L2 guest reboot failure due to empty 'arch_compat'
Currently, rebooting a pseries nested qemu-kvm guest (L2) results in
below error as L1 qemu sends PVR value 'arch_compat' == 0 via
ppc_set_compat ioctl. This triggers a condition failure in
kvmppc_set_arch_compat() resulting in an EINVAL.
qemu-system-ppc64: Unable to set CPU compatibility mode in KVM: Invalid
argument
Also, a value of 0 for arch_compat generally refers the default
compatibility of the host. But, arch_compat, being a Guest Wide Element
in nested API v2, cannot be set to 0 in GSB as PowerVM (L0) expects a
non-zero value. A value of 0 triggers a kernel trap during a reboot and
consequently causes it to fail:

This patch updates kvmppc_set_arch_compat() to use the host PVR value if
'compat_pvr' == 0 indicating that qemu doesn't want to enforce any
specific PVR compat mode.
The relevant part of the code might need a rework if PowerVM implements
a support for `arch_compat == 0` in nestedv2 API.

powerpc/pseries: fix accuracy of stolen time
powerVM hypervisor updates the VPA fields with stolen time data.
It currently reports enqueue_dispatch_tb and ready_enqueue_tb for
this purpose. In linux these two fields are used to report the stolen time.
The VPA fields are updated at the TB frequency. On powerPC its mostly
set at 512Mhz. Hence this needs a conversion to ns when reporting it
back as rest of the kernel timings are in ns. This conversion is already
handled in tb_to_ns function. So use that function to report accurate
stolen time.
Observed this issue and used an Capped Shared Processor LPAR(SPLPAR) to
simplify the experiments. In all these cases, 100% VP Load is run using
stress-ng workload. Values of stolen time is in percentages as reported
by mpstat. With the patch values are close to expected.

registering and unregistering global variables (unlike with -pg and
-mprofile-kernel where calls to _mcount() are not generated in those
functions). Those functions then end up in INIT_TEXT and EXIT_TEXT
respectively. We don't expect to see any profiled functions in
EXIT_TEXT, so ftrace_init_nop() assumes that all addresses that aren't
in the core kernel text belongs to a module. Since these functions do
not match that criteria, we see the above bug.
Address this by having ftrace ignore all locations in the text exit
sections of vmlinux.

powerpc/kasan: Fix addr error caused by page alignment
In kasan_init_region, when k_start is not page aligned, at the begin of
for loop, k_cur = k_start & PAGE_MASK is less than k_start, and then
`va = block + k_cur - k_start` is less than block, the addr va is invalid,
because the memory address space from va to block is not alloced by
memblock_alloc, which will not be reserved by memblock_reserve later, it
will be used by other places.
As a result, memory overwriting occurs.
for example:
int __init __weak kasan_init_region(void *start, size_t size)
{
[...]
/* if say block(dcd97000) k_start(feef7400) k_end(feeff3fe) */
block = memblock_alloc(k_end - k_start, PAGE_SIZE);
[...]
for (k_cur = k_start & PAGE_MASK; k_cur < k_end; k_cur += PAGE_SIZE) {
/* at the begin of for loop
* block(dcd97000) va(dcd96c00) k_cur(feef7000) k_start(feef7400)
* va(dcd96c00) is less than block(dcd97000), va is invalid
*/
void *va = block + k_cur - k_start;
[...]
}
[...]
}
Therefore, page alignment is performed on k_start before
memblock_alloc() to ensure the validity of the VA address.

powerpc/6xx: set High BAT Enable flag on G2_LE cores
MMU_FTR_USE_HIGH_BATS is set for G2_LE cores and derivatives like e300cX,
but the high BATs need to be enabled in HID2 to work. Add register
definitions and add the needed setup to __setup_cpu_603.
This fixes boot on CPUs like the MPC5200B with STRICT_KERNEL_RWX enabled
on systems where the flag has not been set by the bootloader already.

powerpc/64: Set task pt_regs->link to the LR value on scv entry
Nysal reported that userspace backtraces are missing in offcputime bcc
tool. As an example:
$ sudo ./bcc/tools/offcputime.py -uU
Tracing off-CPU time (us) of user threads by user stack... Hit Ctrl-C to end.

- multipathd (697)

The offcputime bcc tool attaches a bpf program to a kprobe on
finish_task_switch(), which is usually hit on a syscall from userspace.
With the switch to system call vectored, we started setting
pt_regs->link to zero. This is because system call vectored behaves like
a function call with LR pointing to the system call return address, and
with no modification to SRR0/SRR1. The LR value does indicate our next
instruction, so it is being saved as pt_regs->nip, and pt_regs->link is
being set to zero. This is not a problem by itself, but BPF uses perf
callchain infrastructure for capturing stack traces, and that stores LR
as the second entry in the stack trace. perf has code to cope with the
second entry being zero, and skips over it. However, generic userspace
unwinders assume that a zero entry indicates end of the stack trace,
resulting in a truncated userspace stack trace.
Rather than fixing all userspace unwinders to ignore/skip past the
second entry, store the real LR value in pt_regs->link so that there
continues to be a valid, though duplicate entry in the stack trace.
With this change:
$ sudo ./bcc/tools/offcputime.py -uU
Tracing off-CPU time (us) of user threads by user stack... Hit Ctrl-C to end.

powerpc/pseries/papr-sysparm: use u8 arrays for payloads
Some PAPR system parameter values are formatted by firmware as
nul-terminated strings (e.g. LPAR name, shared processor attributes).
But the values returned for other parameters, such as processor module
info and TLB block invalidate characteristics, are binary data with
parameter-specific layouts. So char[] isn't the appropriate type for
the general case. Use u8/__u8.

Add a fall back to early_pfn_to_nid() in memmap_init_reserved_pages() to ensure a valid node id is always passed to init_reserved_page(). -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEeOVYVaWZL5900a/pOQOGJssO/ZEFAmW19ekQHHJwcHRAa2Vy bmVsLm9yZwAKCRA5A4Ymyw79kQ2CCAC+aXkQdFbP08jyZ1Q3rjZpXMAq6xORVT1z fWFQQlAQ2L75dWR2dUh+lFPAQRLhs1KfUUmwZUczKhyWXpCFsLLT5OgLtfDLk/sB XzoyZeW7//pSY22mFxcVmOMuJBZ3q+ZB0n9LdhIaWcdedltvEFhVXZjVPFJszszb 8BZIq7tKvUFUv8KOlfGTvjvNjhjmXRRmcrG1fsS4sdkHQ8/36/KjqI0sZUgMq7Fz HfawJ6bK+ysHBmKCuWRAU4ssiuUGSaivqh8Azt+FI/zr2Dk+40asFpE0573VMNB7 MaXAn9TjXKU6e/wMBB7KQSUqIlv3Pm7iK2+B/IP4AJ1cWLylRO1r =efaB -----END PGP SIGNATURE----- Merge tag 'fixes-2024-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock Pull memblock fix from Mike Rapoport: "Fix crash when reserved memory is not added to memory.

mips: Call lose_fpu(0) before initializing fcr31 in mips_set_personality_nan
If we still own the FPU after initializing fcr31, when we are preempted
the dirty value in the FPU will be read out and stored into fcr31,
clobbering our setting. This can cause an improper floating-point
environment after execve(). For example:
zsh% cat measure.c
#include <fenv.h>
int main() { return fetestexcept(FE_INEXACT); }
zsh% cc measure.c -o measure -lm
zsh% echo $((1.0/3)) # raising FE_INEXACT
0.33333333333333331
zsh% while ./measure; do ; done
(stopped in seconds)
Call lose_fpu(0) before setting fcr31 to prevent this.
Closes: https://lore.kernel.org/linux-mips/7a6aa1bbdbbe2e63ae96ff163fab0349f58f1b9e.camel@xry111.site/

MIPS: loongson64: set nid for reserved memblock region
Commit 61167ad5fecd("mm: pass nid to reserve_bootmem_region()") reveals
that reserved memblock regions have no valid node id set, just set it
right since loongson64 firmware makes it clear in memory layout info.
This works around booting failure on 3A1000+ since commit

ata changes for 6.8-rc2
- Fix an incorrect link_power_management_policy sysfs attribute
value. We were previously using the same attribute value for
two different LPM policies (me).
- Add a ASMedia ASM1166 quirk. The SATA host controller always
reports that it has 32 ports, even though it only has six ports.
Add a quirk that overrides the value reported by the controller
(Conrad).
- Add a ASMedia ASM1061 quirk. The SATA host controller completely
ignores the upper 21 bits of the DMA address. This causes IOMMU
error events when a (valid) DMA address actually has any of the
upper 21 bits set. Add a quirk that limits the dma_mask to
43-bits (Lennert).

Power management fixes for 6.8-rc2
- Fix the handling of scaling_max/min_freq sysfs attributes in the AMD
P-state cpufreq driver (Mario Limonciello).
- Make the intel_pstate cpufreq driver avoid unnecessary computation of
the HWP performance level corresponding to a given frequency in the
cases when it is known already, which also helps to avoid reducing
the maximum CPU capacity artificially on some systems (Rafael J.
Wysocki).
- Fix compilation of the cpupower utility when CFLAGS is passed as a
make argument for cpupower, but it does not take effect as expected
due to mishandling (Stanley Chan).

Worth mentioning are three regressions. One of the nouveau fixes in 6.7 for a serious deadlock had side effects, so I guess we will bring back the deadlock until I can figure out what should be done properly. There was a scheduler regression vs amdgpu which was reported in a few places and is now fixed. There was an i915 vs simpledrm problem resulting in black screens, that is reverted also.

As well as a few device IDs and the usual scattering of driver specific fixes this contains a couple of core things. One is a missed case in error handling, the other patch is a change from me raising the number of chip selects allowed by the newly added multi chip select support patches to resolve problems seen on several systems that exceeded the limit. This is not a real solution to the issue but rather just a change to avoid disruption to users, one of the options I am considering is just sending a revert of those changes if we can't come up with something sensible. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmWz7e0ACgkQJNaLcl1U h9BOrAf/UwWplCW+rCznfkb8uAuShKlJux+RtAJZG8A70JeC3jsdN66yUyxmfrIY 5qKtqcPA3VXdM8OQ/3r8tk/q+/2sXESLotefwKvONYrZYmq61lA+rayUiNDQjicJ devvPLns72ZKu3VpsdFAoXzA+mL8Byp65lBqW5dHVyt0itY1Ap2Zdi8CNSzEVLLs 3Qhe26yy8sxILQZ6N4TSNYMV7l6yn3AjZ5kUDFi/CA1AWTTfazpioCAyADa3iTpR 1i0zsMzeDEL0iu8gWuB62mqftwY5ua3NaSmpxWPebG4VtMXqu62PwQugiqmq+gDc bA0SLlzR4xub7dtyhEjmsCbn4pvafw== =RQ5N -----END PGP SIGNATURE----- Merge tag 'spi-fix-v6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "As well as a few device IDs and the usual scattering of driver specific fixes this contains a couple of core things.
