7b6ece968f remoteproc: qcom: pas: Check if coredump is enabled
Client drivers need to check if coredump is enabled for the rproc before
continuing with coredump generation. This change adds a check in the PAS
driver.

dc86c129b4 remoteproc: qcom: pas: Mark devices as wakeup capable
device_wakeup_enable() on its own is not capable of setting
device as wakeup capable, it needs to be used in conjunction
with device_set_wakeup_capable(). The device_init_wakeup()

5ddf5969e9 remoteproc: qcom: pas: Mark va as io memory
The pas driver remaps the entire carveout region using the dev_ioremap_wc()
call, which is then used in the adsp_da_to_va() calls made by the rproc
framework. This change marks the va returned by this call as an iomem va.

This patch is for enabling cache in SCP. There is not enough space
on the SRAM of SCP. We need to run programs in DRAM. The DRAM power
and latency is much larger than SRAM, so cache is used to mitigate
the negative effects for performance. We set SCP registers for cache
size before loading SCP FW. (8KB+8KB) and also adjust ipi_buf_offset
in SRAM from 0x7bdb0 to 0x3bdb0 for enabling cache.

fa220c05d2 remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init
Every iteration of for_each_available_child_of_node() decrements
the reference count of the previous node.
When breaking early from a for_each_available_child_of_node() loop,
we need to explicitly call of_node_put() on the child node.
Add missing of_node_put() to avoid refcount leak.

Merge tag 'random-5.19-rc2-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random

Pull random number generator fixes from Jason Donenfeld:

 - A fix for a 5.19 regression for a case in which early device tree
   initializes the RNG, which flips a static branch.

   On most plaforms, jump labels aren't initialized until much later, so
   this caused splats. On a few mailing list threads, we cooked up easy
   fixes for arm64, arm32, and risc-v. But then things looked slightly
   more involved for xtensa, powerpc, arc, and mips. And at that point,
   when we're patching 7 architectures in a place before the console is
   even available, it seems like the cost/risk just wasn't worth it.

   So random.c works around it now by checking the already exported
   `static_key_initialized` boolean, as though somebody already ran into
   this issue in the past. I'm not super jazzed about that; it'd be
   prettier to not have to complicate downstream code. But I suppose
   it's practical.

 - A few small code nits and adding a missing __init annotation.

 - A change to the default config values to use the cpu and bootloader's
   seeds for initializing the RNG earlier.

   This brings them into line with what all the distros do (Fedora/RHEL,
   Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
   least), and moreover will now give us test coverage in various test
   beds that might have caught the above device tree bug earlier.

 - A change to WireGuard CI's configuration to increase test coverage
   around the RNG.

 - A documentation comment fix to unrelated maintainerless CRC code that
   I was asked to take, I guess because it has to do with polynomials
   (which the RNG thankfully no longer uses).

commit be9d73e649 ("platform/x86: hp-wmi: Fix 0x05 error code reported by
several WMI calls") and commit 12b19f14a2 ("platform/x86: hp-wmi: Fix
hp_wmi_read_int() reporting error (0x05)") cause ACPI BIOS Error (bug):
Attempt to CreateField of length zero (20211217/dsopcode-133) because of
the ACPI method HWMC, which unconditionally creates a Field of
size (insize*8) bits:
	CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)
In cases where args->insize = 0, the Field size is 0, resulting in
an error.

Fix this by using zero insize only if 0x5 error code is returned

Tested on Omen 15 AMD (2020) board ID: 8786.

dc6a6ab583 platform/x86: hp-wmi: Resolve WMI query failures on some devices
WMI queries fail on some devices where the ACPI method HWMC
unconditionally attempts to create Fields beyond the buffer
if the buffer is too small, this breaks essential features
such as power profiles:

         CreateByteField (Arg1, 0x10, D008)
         CreateByteField (Arg1, 0x11, D009)
         CreateByteField (Arg1, 0x12, D010)
         CreateDWordField (Arg1, 0x10, D032)
         CreateField (Arg1, 0x80, 0x0400, D128)

In cases where args->data had zero length, ACPI BIOS Error
(bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit
offset/length 128/8 exceeds size of target Buffer (128 bits)
(20211217/dsopcode-198) was obtained.

ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit
offset/length 136/8 exceeds size of target Buffer (136bits)
(20211217/dsopcode-198)

The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not.  This particular
behavior occurs in older BIOS and reproduced in OMEN laptops.  Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements.  This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.

This patch was tested on several OMEN, Elite, and Zbooks.  It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx.  No problems were reported when testing on several Elite
and Zbooks notebooks.

1c27f1fc15 iov_iter: fix build issue due to possible type mis-match
Commit 6c77676645 ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
introduced a problem on some 32-bit architectures (at least arm, xtensa,
csky,sparc and mips), that have a 'size_t' that is 'unsigned int'.

The reason is that we now do

    min(nr * PAGE_SIZE - offset, maxsize);

where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is
'unsigned long'.  As a result, the normal C type rules means that the
first argument to 'min()' ends up being 'unsigned long'.

In contrast, 'maxsize' is of type 'size_t'.

Now, 'size_t' and 'unsigned long' are always the same physical type in
the kernel, so you'd think this doesn't matter, and from an actual
arithmetic standpoint it doesn't.

But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if
it could also be 'unsigned long'.  In that situation, both are unsigned
32-bit types, but they are not the *same* type.

And as a result 'min()' will complain about the distinct types (ignore
the "pointer types" part of the error message: that's an artifact of the
way we have made 'min()' check types for being the same):

  lib/iov_iter.c: In function 'iter_xarray_get_pages':
  include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]
     20 |         (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
        |                                   ^~
  lib/iov_iter.c:1464:16: note: in expansion of macro 'min'
   1464 |         return min(nr * PAGE_SIZE - offset, maxsize);
        |                ^~~

This was not visible on 64-bit architectures (where we always define
'size_t' to be 'unsigned long').

Force these cases to use 'min_t(size_t, x, y)' to make the type explicit
and avoid the issue.

[ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned
  long' arithmetically. We've certainly historically seen environments
  with 16-bit address spaces and 32-bit 'unsigned long'.

  Similarly, even in 64-bit modern environments, 'size_t' could be its
  own type distinct from 'unsigned long', even if it were arithmetically
  identical.

  So the above type commentary is only really descriptive of the kernel
  environment, not some kind of universal truth for the kinds of wild
  and crazy situations that are allowed by the C standard ]

17b0128a13 wireguard: selftests: use maximum cpu features and allow rng seeding
By forcing the maximum CPU that QEMU has available, we expose additional
capabilities, such as the RNDR instruction, which increases test
coverage. This then allows the CI to skip the fake seeding step in some
cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
jump labels when the RNG is initialized at boot.

1f7a6cf6b0 scripts/gdb: change kernel config dumping method
MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out
from the kernel_config_data variable.

Thus, we parse kernel_config_data directly instead of considering
offset of MAGIC_START and MAGIC_END.
