pinctrl: mcp23s08: Rename and change function that wraps regmap_update_bits()
The semantic of mcp_set_mask() was surprising to me when I first read
that driver. So it was unexpected that in the call
mcp_set_mask(mcp, MCP_OLAT, mask, value);
value was a bool. Make the function a thinner wrapper around
regmap_update_bits() and rename it to also have a similar name.

pinctrl: qcom: Support OUTPUT_ENABLE; deprecate INPUT_ENABLE
The Qualcomm pinctrl driver has been violating the documented meaning
of PIN_CONFIG_INPUT_ENABLE. That documentation says:
Note that this does not affect the pin's ability to drive output.
...yet the Qualcomm driver's sole action when asked to "enable input"
on a pin is to disable its output.
The Qualcomm driver's implementation stems from the fact that
"output-disable" is a "new" property from 2017. It was introduced in
commit
425562429d4f ("pinctrl: generic: Add output-enable
property"). The "input-enable" handling in Qualcomm drivers is from
2015 introduced in commit
407f5e392f9c ("pinctrl: qcom: handle
input-enable pinconf property").
Let's change the Qualcomm driver to move us in the right direction. As
part of this:
1. We'll now support PIN_CONFIG_OUTPUT_ENABLE
2. We'll still support using PIN_CONFIG_INPUT_ENABLE to disable a
pin's output (in violation of the docs) with a big comment in the
code. This is needed because old device trees have "input-enable"
in them and, in some cases, people might need the old
behavior. While we could programmatically change all old device
trees, it doesn't really hurt to keep supporting the old behavior
and we're _supposed_ to try to be compatible with old device trees
anyway.
It can also be noted that the PIN_CONFIG_INPUT_ENABLE handling code
seems to have purposefully ignored its argument. That means that old
boards that had _either_ "input-disable" or "input-enable" in them
would have had the effect of disabling a pin's output. While we could
change this behavior, since we're only leaving the
PIN_CONFIG_INPUT_ENABLE there for backward compatibility we might as
well be fully backward compatible.
NOTE: despite the fact that we'll still support
PIN_CONFIG_INPUT_ENABLE for _setting_ config, we take it away from
msm_config_group_get(). This appears to be only used for populating
debugfs and fixing debugfs to "output enabled" where relevant instead
of "input enabled" makes more sense and has more truthiness.

dt-bindings: pinctrl: qcom: Add output-enable
In the patch ("dt-bindings: pinctrl: qcom: tlmm should use
output-disable, not input-enable") we allowed setting "output-disable"
for TLMM pinctrl states. Let's also add "output-enable".
At first blush this seems a needless thing to do. Specifically:
- In Linux (and presumably any other OSes using the same device trees)
the GPIO/pinctrl driver knows to automatically enable the output
when a GPIO is changed to an output. Thus in most cases specifying
"output-enable" is superfluous and should be avoided.
- If we need to set a pin's default state we already have
"output-high" and "output-low" and these properties already imply
"output-enabled" (at least on the Linux Qualcomm TLMM driver).
However, there is one instance where "output-enable" seems like it
could be useful: sleep states. It's not uncommon to want to configure
pins as inputs (with appropriate pulls) when the driver controlling
them is in a low power state. Then we want the pins back to outputs
when the driver wants things running normally. To accomplish this we'd
want to be able to use "output-enable". Then the "default" state could
have "output-enable" and the "sleep" state could have
"output-disable".
NOTE: in all instances I'm aware of, we'd only want to use
"output-enable" on pins that are configured as "gpio". The Qualcomm
documentation that I have access to says that "output-enable" only
does something useful when in GPIO mode.

dt-bindings: pinctrl: qcom: tlmm should use output-disable, not input-enable
As evidenced by the Qualcomm TLMM Linux driver, the TLMM IP block in
Qualcomm SoCs has a bit to enable/disable the output for a pin that's
configured as a GPIO but _not_ a bit to enable/disable an input
buffer. Current device trees that are specifying "input-enable" for
pins managed by TLMM are either doing so needlessly or are using it to
mean "output-disable".
Presumably the current convention of using "input-enable" to mean
"output-disable" stems from the fact that "output-disable" is a "new"
property from 2017. It was introduced in commit
425562429d4f
("pinctrl: generic: Add output-enable property"). The "input-enable"
handling in Qualcomm drivers is from 2015 introduced in commit
407f5e392f9c ("pinctrl: qcom: handle input-enable pinconf property").
Given that there's no other use for "input-enable" for TLMM, we can
still handle old device trees in code, but let's encourage people to
move to the proper / documented property by updating the bindings.

cpumask: re-introduce constant-sized cpumask optimizations
Commit
aa47a7c215e7 ("lib/cpumask: deprecate nr_cpumask_bits") resulted
in the cpumask operations potentially becoming hugely less efficient,
because suddenly the cpumask was always considered to be variable-sized.
The optimization was then later added back in a limited form by commit
6f9c07be9d02 ("lib/cpumask: add FORCE_NR_CPUS config option"), but that
FORCE_NR_CPUS option is not useful in a generic kernel and more of a
special case for embedded situations with fixed hardware.
Instead, just re-introduce the optimization, with some changes.
Instead of depending on CPUMASK_OFFSTACK being false, and then always
using the full constant cpumask width, this introduces three different
cpumask "sizes":
- the exact size (nr_cpumask_bits) remains identical to nr_cpu_ids.
This is used for situations where we should use the exact size.
- the "small" size (small_cpumask_bits) is the NR_CPUS constant if it
fits in a single word and the bitmap operations thus end up able
to trigger the "small_const_nbits()" optimizations.
This is used for the operations that have optimized single-word
cases that get inlined, notably the bit find and scanning functions.
- the "large" size (large_cpumask_bits) is the NR_CPUS constant if it
is an sufficiently small constant that makes simple "copy" and
"clear" operations more efficient.
This is arbitrarily set at four words or less.
As a an example of this situation, without this fixed size optimization,
cpumask_clear() will generate code like
movl nr_cpu_ids(%rip), %edx
addq $63, %rdx
shrq $3, %rdx
andl $-8, %edx
callq memset@PLT
on x86-64, because it would calculate the "exact" number of longwords
that need to be cleared.
In contrast, with this patch, using a MAX_CPU of 64 (which is quite a
reasonable value to use), the above becomes a single
movq $0,cpumask
instruction instead, because instead of caring to figure out exactly how
many CPU's the system has, it just knows that the cpumask will be a
single word and can just clear it all.
Note that this does end up tightening the rules a bit from the original
version in another way: operations that set bits in the cpumask are now
limited to the actual nr_cpu_ids limit, whereas we used to do the
nr_cpumask_bits thing almost everywhere in the cpumask code.
But if you just clear bits, or scan for bits, we can use the simpler
compile-time constants.
In the process, remove 'cpumask_complement()' and 'for_each_cpu_not()'
which were not useful, and which fundamentally have to be limited to
'nr_cpu_ids'. Better remove them now than have somebody introduce use
of them later.
Of course, on x86-64 with MAXSMP there is no sane small compile-time
constant for the cpumask sizes, and we end up using the actual CPU bits,
and will generate the above kind of horrors regardless. Please don't
use MAXSMP unless you really expect to have machines with thousands of
cores.

Correct action in such case is not "return unconditionally" - fatal
signals are handled only upon return to userland and something like
copy_to_user() would end up retrying the faulting instruction and
triggering the same fault again and again.
What we need to do in such case is to make the caller to treat that as
failed uaccess attempt - handle exception if there is an exception
handler for faulting instruction or oops if there isn't one.
Over the years some architectures had been fixed and now are handling
that case properly; some still do not. This series should fix the

mm: avoid gcc complaint about pointer casting
The migration code ends up temporarily stashing information of the wrong
type in unused fields of the newly allocated destination folio. That
all works fine, but gcc does complain about the pointer type mis-use:
mm/migrate.c: In function ‘__migrate_folio_extract’:
mm/migrate.c:1050:20: note: randstruct: casting between randomized structure pointer types (ssa): ‘struct anon_vma’ and ‘struct address_space’
1050 | *anon_vmap = (void *)dst->mapping;
| ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
and gcc is actually right to complain since it really doesn't understand
that this is a very temporary special case where this is ok.
This could be fixed in different ways by just obfuscating the assignment
sufficiently that gcc doesn't see what is going on, but the truly
"proper C" way to do this is by explicitly using a union.
Using unions for type conversions like this is normally hugely ugly and
syntactically nasty, but this really is one of the few cases where we
want to make it clear that we're not doing type conversion, we're really
re-using the value bit-for-bit just using another type.
IOW, this should not become a common pattern, but in this one case using
that odd union is probably the best way to document to the compiler what
is conceptually going on here.
[ Side note: there are valid cases where we convert pointers to other
pointer types, notably the whole "folio vs page" situation, where the
types actually have fundamental commonalities.
The fact that the gcc note is limited to just randomized structures
means that we don't see equivalent warnings for those cases, but it
migth also mean that we miss other cases where we do play these kinds
of dodgy games, and this kind of explicit conversion might be a good
idea. ]
I verified that at least for an allmodconfig build on x86-64, this
generates the exact same code, apart from line numbers and assembler
comment changes.

umh: simplify the capability pointer logic
The usermodehelper code uses two fake pointers for the two capability
cases: CAP_BSET for reading and writing 'usermodehelper_bset', and
CAP_PI to read and write 'usermodehelper_inheritable'.
This seems to be a completely unnecessary indirection, since we could
instead just use the pointers themselves, and never have to do any "if
this then that" kind of logic.
So just get rid of the fake pointer values, and use the real pointer
values instead.

i2c: Disable I2C_APPLE when I2C_PASEMI is a builtin
The ppc64le_allmodconfig sets I2C_PASEMI=y and leaves COMPILE_TEST to
default to y and I2C_APPLE to default to m, running into a known
incompatible configuration that breaks the build [1]. Specifically,
a common dependency (i2c-pasemi-core.o in this case) cannot be used by
both builtin and module consumers.
Disable I2C_APPLE when I2C_PASEMI is a builtin to prevent this.
