seq_printf() is more expensive than seq_put_decimal_ull_width() due to the
format string parsing costs.
Profiling on a x86 8-core system indicates seq_printf() takes ~47% samples
of show_interrupts(). Replacing it with seq_put_decimal_ull_width() yields
almost 30% performance gain.

Filesystem options can be retrieved with STATMOUNT_MNT_OPTS, which
returns a string of comma separated options, where some characters are
escaped using the \OOO notation.
Add a new flag, STATMOUNT_OPT_ARRAY, which instead returns the raw
option values separated with '\0' charaters.
Since escaped charaters are rare, this inteface is preferable for
non-libmount users which likley don't want to deal with option
de-escaping.
Example code:
if (st->mask & STATMOUNT_OPT_ARRAY) {
const char *opt = st->str + st->opt_array;
for (unsigned int i = 0; i < st->opt_num; i++) {
printf("opt_array[%i]: <%s>\n", i, opt);
opt += strlen(opt) + 1;
}
}
Example ouput:
(1) mnt_opts: <lowerdir+=/l\054w\054r,lowerdir+=/l\054w\054r1,upperdir=/upp\054r,workdir=/w\054rk,redirect_dir=nofollow,uuid=null>

Starting from LNL, CCS has moved over to flat CCS model where there is
now dedicated memory reserved for storing compression state. On
platforms like LNL this reserved memory lives inside graphics stolen
memory, which is not treated like normal RAM and is therefore skipped by
the core kernel when creating the hibernation image. Currently if
something was compressed and we enter hibernation all the corresponding
CCS state is lost on such HW, resulting in corrupted memory. To fix this
evict user buffers from TT -> SYSTEM to ensure we take a snapshot of the
raw CCS state when entering hibernation, where upon resuming we can
restore the raw CCS state back when next validating the buffer. This has
been confirmed to fix display corruption on LNL when coming back from
hibernation.

The GGTT looks to be stored inside stolen memory on igpu which is not
treated as normal RAM. The core kernel skips this memory range when
creating the hibernation image, therefore when coming back from
hibernation the GGTT programming is lost. This seems to cause issues
with broken resume where GuC FW fails to load:
[drm] *ERROR* GT0: load failed: status = 0x400000A0, time = 10ms, freq = 1250MHz (req 1300MHz), done = -1
[drm] *ERROR* GT0: load failed: status: Reset = 0, BootROM = 0x50, UKernel = 0x00, MIA = 0x00, Auth = 0x01
[drm] *ERROR* GT0: firmware signature verification failed
[drm] *ERROR* CRITICAL: Xe has declared device 0000:00:02.0 as wedged.
Current GGTT users are kernel internal and tracked as pinned, so it
should be possible to hook into the existing save/restore logic that we
use for dgpu, where the actual evict is skipped but on restore we
importantly restore the GGTT programming. This has been confirmed to
fix hibernation on at least ADL and MTL, though likely all igpu
platforms are affected.
This also means we have a hole in our testing, where the existing s4
tests only really test the driver hooks, and don't go as far as actually
rebooting and restoring from the hibernation image and in turn powering
down RAM (and therefore losing the contents of stolen).

Implement support for the word delay feature of i.MX51 (and onwards) via
the ECSPI interface.
Convert the requested delay to SPI cycles and account for an extra
inter-word delay inserted by the controller in addition to the requested
number of cycles, which was observed when testing this patch.
Disable dynamic burst when word delay is set. As the configurable delay
period in the controller is inserted after bursts, the burst length must
equal the word length.
Account for word delay in the transfer time estimation for
polling_limit_us.

Since gcc supports flag out operands for inline assemblies there is always
the question when this feature should be used and if it is worth all the
ifdefs that come with that.
In order to avoid that provide similar macros like x86 which can be used
for all inline assemblies which extract the condition code. Depending on
compiler features the generated code will either always contain an ipm+srl
instruction pair, which extracts the condition code, or alternatively let
the compiler handle this completely.

Jeff Layton <jlayton@kernel.org> says:
Meta has some internal logging that scrapes /proc/self/mountinfo today.
I'd like to convert it to use listmount()/statmount(), so we can do a
better job of monitoring with containers. We're missing some fields
though. This patchset adds them.
* patches from https://lore.kernel.org/r/20241111-statmount-v4-0-2eaf35d07a80@kernel.org:
fs: add the ability for statmount() to report the sb_source
fs: add the ability for statmount() to report the fs_subtype
fs: don't let statmount return empty strings

/proc/self/mountinfo displays the source for the mount, but statmount()
doesn't yet have a way to return it. Add a new STATMOUNT_SB_SOURCE flag,
claim the 32-bit __spare1 field to hold the offset into the str[] array.

This patch adds MT7530 & MT7531's PHY ID macros in mtk-ge.c so that
it follows the same rule of mtk-ge-soc.c.

This patch integrates read/write page helper functions as MTK phy lib.
They are basically the same in mtk-ge.c & mtk-ge-soc.c.
