The pci-rcar driver is enabled for compile tests, and this has shown that
the driver cannot build without CONFIG_OF, following the inclusion of
commit f8f2fe7355 ("PCI: rcar: Use new OF interrupt mapping when possible"):

^
As pointed out by Ben Dooks and Geert Uytterhoeven, this is actually
supposed to build fine, which we can achieve if we make the declaration
of of_irq_parse_and_map_pci conditional on CONFIG_OF and provide an
empty inline function otherwise, as we do for a lot of other of
interfaces.
This lets us build the rcar_pci driver again without CONFIG_OF for build
testing. All platforms using this driver select OF, so this doesn't
change anything for the users.

The driver had a type mismatch since it was first merged, but
this never caused problems because it is only built on 64-bit

If we ever want to compile-test the driver on 32-bit or change

gcc warns that the length for the extra unaligned data in the hash
function may be used unaligned. In theory this could happen if
we pass a zero-length sg_list, or if sg_is_last() was never true:
In file included from drivers/crypto/stm32/stm32-hash.c:23:
drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_one_request':

#define __KERNEL_DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d))
Neither of these can happen in practice, so the warning is harmless.
However while trying to suppress the warning, I noticed multiple
problems with that code:
- On big-endian kernels, we byte-swap the data like we do for
register accesses, however this is a data stream and almost
certainly needs to use a single writesl() instead of series
of writel() to give the correct hash.
- If the length is not a multiple of four bytes, we skip the
last word entirely, since we write the truncated length
using stm32_hash_set_nblw().
- If we change the code to round the length up rather than
down, the last bytes contain stale data, so it needs some
form of padding.
This tries to address all four problems, by correctly
initializing the length to zero, using endian-safe copy
functions, adding zero-padding and passing the padded length.
I have done no testing on this patch, so please review
carefully and if possible test with an unaligned length
and big-endian kernel builds.

With KASAN and a couple of other patches applied, this driver is one
of the few remaining ones that actually use more than 2048 bytes of
kernel stack:
broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy_gainctrl':

Here, I'm reducing the stack size by marking as many local variables as
'static const' as I can without changing the actual code.
This is the first of three patches to improve the stack usage in this
driver. It would be good to have this backported to stabl kernels
to get all drivers in 'allmodconfig' below the 2048 byte limit so
we can turn on the frame warning again globally, but I realize that
the patch is larger than the normal limit for stable backports.
The other two patches do not need to be backported.

When CONFIG_KASAN is enabled, the "--param asan-stack=1" causes rather large

CONFIG_FRAME_WARN is disabled with CONFIG_KASAN by default as of commit
3f181b4d86 ("lib/Kconfig.debug: disable -Wframe-larger-than warnings with
KASAN=y").
The kernelci.org build bot however has the warning enabled and that led
me to investigate it a little further, as every build produces these warnings:

Most of this problem is now solved in gcc-8, which can consolidate
the stack slots for the inline function arguments. On older compilers
we can add a workaround by declaring a local variable in each function
to pass the inline function argument.

We copy a local resource structure into a list, but only

Newer compilers can presumably optimize the uninitialized access

to zero the structure first. This adds an explicit initialization
to force consistent behavior.

This adds extra type casts to avoid the warning.
However, there is another problem with the Kconfig option: turning
it on or off creates two incompatible ABI versions, a kernel that
has this enabled cannot run user space that was built without it
or vice versa. A better solution might be to leave the option hidden
until the binder code is fixed to deal with both ABI versions.

The new lockdep support for completions causeed the stack usage
in dm-integrity to explode, in case of write_journal from 504 bytes
to 1120 (using arm gcc-7.1.1):
drivers/md/dm-integrity.c: In function 'write_journal':
drivers/md/dm-integrity.c:827:1: error: the frame size of 1120 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
The problem is that not only the size of 'struct completion' grows
significantly, but we end up having multiple copies of it on the stack
when we assign it from a local variable after the initial declaration.
COMPLETION_INITIALIZER_ONSTACK() is the right thing to use when we
want to declare and initialize a completion on the stack. However,
this driver doesn't do that and instead initializes the completion
just before it is used.
In this case, init_completion() does the same thing more efficiently,
and drops the stack usage for the function above down to 496 bytes.
While the other functions in this file are not bad enough to cause
a warning, they benefit equally from the change, so I do the change
across the entire file. In the one place where we reuse a completion,
I picked the cheaper reinit_completion() over init_completion().

Making some functions 'static' has uncovered a few functions that
have no caller, through the gcc warnings:

atomisp/i2c/imx/imx.c:1087:12: error: 'imx_vcm_power_up' defined but not used [-Werror=unused-function]
All four of these can be removed. Since they call indirect functions,
I also looked at how those are used in turn:
- The power_up/power_down callbacks are called from other functions
and are still needed.
- The t_focus_vcm callbacks pointers are completely unused and can
be removed in both imx and ov8858. Some of the handlers are called
directly and can now be marked static, the others are dummy
implemntations that we can remove.
- vcm_init is unused in imx, but dw9718_vcm_init is used in ov8858,
but is not used in imx, so that one needs to stay around. The callback
pointers in imx can be removed.

This is an interesting regression with gcc-8, showing a harmless warning

I managed to reduce the warning into a small test case for gcc-8 that I
reported in the gcc bugzilla[1].
As a workaround, this changes the logic to move the two assignments of
'eq' out of the conditions and instead make the index conditional. This
works for all configurations I tried and avoids adding a bogus
initialization.

gcc-8.0.0 (snapshot) points out that we copy a variable-length string
into a fixed length field using memcpy() with the destination length,
and that ends up copying whatever follows the string:
inlined from 'ql_core_dump' at drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:1106:2:
drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:708:2: error: 'memcpy' reading 15 bytes from a region of size 14 [-Werror=stringop-overflow=]
memcpy(seg_hdr->description, desc, (sizeof(seg_hdr->description)) - 1);
Changing it to use strncpy() will instead zero-pad the destination,
which seems to be the right thing to do here.
The bug is probably harmless, but it seems like a good idea to address
it in stable kernels as well, if only for the purpose of building with
gcc-8 without warnings.

orion_nand_read_buf uses an inline assembly with the "ldrd"
instruction, which is only available from ARMv5 upwards. This
used to be fine, since all users have an ARMv5 or ARMv7 CPU,
but now we can also build a multiplatform kernel with ARMv4
support enabled in addition to the "kirkwood" (mvebu) platform.
This provides an alternative to call the readsl() function that
is supposed to have the same effect and is also optimized for
performance.
I first posted a version of this patch back in 2014, and there
was some discussion about it then. This fixes the bugs identified
back then and should be a reasonable alternative for the rare
corner case.

Commit 971a69db7d ("Xen: don't warn about 2-byte wchar_t in efi")
added the --no-wchar-size-warning to the Makefile to avoid this
harmless warning:
arm-linux-gnueabi-ld: warning: drivers/xen/efi.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail
Changing kbuild to use thin archives instead of recursive linking
unfortunately brings the same warning back during the final link.
The kernel does not use wchar_t string literals at this point, and
xen does not use wchar_t at all (only efi_char16_t), so the flag
has no effect, but as pointed out by Jan Beulich, adding a wchar_t
string literal would be bad here.
Since wchar_t is always defined as u16, independent of the toolchain
default, always passing -fshort-wchar is correct and lets us
remove the Xen specific hack along with fixing the warning.
