XBAR_DIVBUS and AD_SLOW should set parent to XBAR_AD_DIVPLAT and
XBAR_DIVBUS respectively, not the NIC_AD. otherwise we will get
wrong clock rate.

Add mcore_booted boot parameter which could simplify AMP clock
management. To i.MX93, there is CCM(clock control Module) to generate
clock root clock, anatop(analog PLL module) to generate PLL, and LPCG
(clock gating) to gate clocks to peripherals. As below:
anatop->ccm->lpcg->peripheral
Linux handles the clock management and the auxiliary core is under
control of Linux. Although there is per hardware domain control for LPCG
and CCM, auxiliary core normally only use LPCG hardware domain control
to avoid linux gate off the clk to peripherals and leave CCM ana anatop
to Linux.

The fracn gppll could be configured in FRAC or INTEGER mode during
hardware design. The current driver only support FRAC mode, while
this patch introduces INTEGER support. When the PLL is INTEGER pll,
there is no mfn, mfd, the calculation is as below:
Fvco_clk = (Fref / DIV[RDIV] ) * DIV[MFI]
Fclko_odiv = Fvco_clk / DIV[ODIV]
In this patch, we reuse the FRAC pll logic with some condition check to
simplify the driver

By default the display pixel clock needs to be evenly divide
down from the video_pll_out clock which rules out a significant
number of resolution and refresh rates.
The current clock tree looks something like:
video_pll 594000000
video_pll_bypass 594000000
video_pll_out 594000000
disp_pixel 148500000
disp_pixel_clk 148500000
Now that composite-8m supports determine_rate, we can allow
disp_pixel to set the parent rate which then switches
every clock in the chain to a new frequency when disp_pixel
cannot evenly divide from video_pll_out.

Similar to imx/clk-composite-93 and imx/clk-divider-gate, the
imx8m_clk_composite_divider_ops can support determine_rate.
Without this the parent clocks are set to a fixed value, and
if a consumer needs a slower reate, the clock is divided, but
the division is only as good as the parent clock rate.
With this added, the system can attempt to adjust the parent rate
if the proper flags are set which can lead to a more precise clock
value.

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.

correctly:
- handle_mm_fault() has returned VM_FAULT_RETRY

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.

that case properly; some still do not. This series should fix the

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.

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.

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.
