This pull request includes a number of patches that didn't quite make
the cut last merge window while we addressed some outstanding issues
and review comments. It includes some new caching modes for those that
only want readahead caches and reworks how we do writeback caching so we
are not keeping extra references around which both causes performance problems
and uses lots of additional resources on the server.
It also includes a new flag to force disabling of xattrs which can also
cause major performance issues, particularly if the underlying filesystem
on the server doesn't support them.
Finally it adds a couple of additional mount options to better support
directio and enabling caches when the server doesn't support qid.version.
There was one late-breaking bug report that has also been included as its
own patch where I forgot to propagate an embarassing bit-logic fix to the
various variations of open. Since that was only added to for-next a week
ago, if you would like to not include it, I can include it in the first
round of fixes for -rc2.

That time is now and things are looking good. We only have one stragglers
on the patch which had already an ACK for so I'm picking this up here now and
the last patch is the one that uses an axe. Some careful eyeballing would
be appreciated by others. If this doesn't get properly reviewed I can also
just hold off on this in my tree for the next merge window. Either way is
fine by me.
I have boot tested the last patch and 0-day build completed successfully.

Fix the argument pointer (ap) to point to real-mode memory
instead of virtual memory.
It's interesting that this issue hasn't shown up earlier, as this could
have happened with any 64-bit PDC ROM code.
I just noticed it because I suddenly faced a HPMC while trying to execute
the 64-bit STI ROM code of an Visualize-FXe graphics card for the STI
text console.

This change simplifies the randomization of file mapping regions. It
reworks the code to remove duplication. The flow is now similar to
that for mips. Finally, we consistently use the do_color_align variable
to determine when color alignment is needed.
Tested on rp3440.

Matthew Wilcox noticed, that if ARCH_HAS_FLUSH_ON_KUNMAP is defined
(which is the case for PA-RISC), __kunmap_local() calls
kunmap_flush_on_unmap(), which may call the parisc flush functions with
a non-page-aligned address and thus the page might not be fully flushed.
This patch ensures that flush_kernel_dcache_page_asm() and
flush_kernel_dcache_page_asm() will always operate on page-aligned
addresses.

function are off, so it's very dangerous to wait on a regular
spinlock, there's a risk of deadlock.
Refactor the panic notifier of parisc/power driver to make use
of spin_trylock - for that, we've added a second version of the
soft-power function. Also, some comments were reorganized and
trailing white spaces, useless header inclusion and blank lines
were removed.

The deprecation for register_sysctl_paths() is over. We can rejoice as
we nuke register_sysctl_paths(). The routine register_sysctl_table()
was the only user left of register_sysctl_paths(), so we can now just
open code and move the implementation over to what used to be
to __register_sysctl_paths().
The old dynamic struct ctl_table_set *set is now the point to
sysctl_table_root.default_set.
The old dynamic const struct ctl_path *path was being used in the
routine register_sysctl_paths() with a static:
static const struct ctl_path null_path[] = { {} };
Since this is a null path we can now just simplfy the old routine
and remove its use as its always empty.
This saves us a total of 230 bytes.

The refactoring in commit f4e9e0e694 ("mm/mempolicy: fix use-after-free
of VMA iterator") introduces a subtle bug which arises when attempting to
apply a new NUMA policy across a range of VMAs in mbind_range().
The refactoring passes a **prev pointer to keep track of the previous VMA
in order to reduce duplication, and in all but one case it keeps this
correctly updated.
The bug arises when a VMA within the specified range has an equivalent
policy as determined by mpol_equal() - which unlike other cases, does not
update prev.
This can result in a situation where, later in the iteration, a VMA is
found whose policy does need to change. At this point, vma_merge() is
invoked with prev pointing to a VMA which is before the previous VMA.
Since vma_merge() discovers the curr VMA by looking for the one
immediately after prev, it will now be in a situation where this VMA is
incorrect and the merge will not proceed correctly.
This is checked in the VM_WARN_ON() invariant case with end >
curr->vm_end, which, if a merge is possible, results in a warning (if
CONFIG_DEBUG_VM is specified).
I note that vma_merge() performs these invariant checks only after
merge_prev/merge_next are checked, which is debatable as it hides this
issue if no merge is possible even though a buggy situation has arisen.
The solution is simply to update the prev pointer even when policies are
equal.
This caused a bug to arise in the 6.2.y stable tree, and this patch
resolves this bug.

Generally, the '->write_iter' of file ops will use copy_page_from_iter()
and copy_page_from_iter_atomic(), change memcpy() to copy_mc_to_kernel()
in both of them to handle #MC during source read, which stop coredump
processing and kill the task instead of kernel panic, but the source
address may not always a user address, so introduce a new copy_mc flag in
struct iov_iter{} to indicate that the iter could do a safe memory copy,
also introduce the helpers to set/cleck the flag, for now, it's only used
in coredump's dump_user_range(), but it could expand to any other
scenarios to fix the similar issue.

Now the __pageblock_pfn_to_page() is used by set_zone_contiguous(), which
checks whether the given zone contains holes, and uses
pfn_to_online_page() to validate if the start pfn is online and valid, as
well as using pfn_valid() to validate the end pfn.
However, the __pageblock_pfn_to_page() function may return non-NULL even
if the end pfn of a pageblock is in a memory hole in some situations. For
example, if the pageblock order is MAX_ORDER, which will fall into 2
sub-sections, and the end pfn of the pageblock may be hole even though the
start pfn is online and valid.
See below memory layout as an example and suppose the pageblock order is
MAX_ORDER.
[ 0.000000] Zone ranges:
[ 0.000000] DMA [mem 0x0000000040000000-0x00000000ffffffff]
[ 0.000000] DMA32 empty
[ 0.000000] Normal [mem 0x0000000100000000-0x0000001fa7ffffff]
[ 0.000000] Movable zone start for each node
[ 0.000000] Early memory node ranges
[ 0.000000] node 0: [mem 0x0000000040000000-0x0000001fa3c7ffff]
[ 0.000000] node 0: [mem 0x0000001fa3c80000-0x0000001fa3ffffff]
[ 0.000000] node 0: [mem 0x0000001fa4000000-0x0000001fa402ffff]
[ 0.000000] node 0: [mem 0x0000001fa4030000-0x0000001fa40effff]
[ 0.000000] node 0: [mem 0x0000001fa40f0000-0x0000001fa73cffff]
[ 0.000000] node 0: [mem 0x0000001fa73d0000-0x0000001fa745ffff]
[ 0.000000] node 0: [mem 0x0000001fa7460000-0x0000001fa746ffff]
[ 0.000000] node 0: [mem 0x0000001fa7470000-0x0000001fa758ffff]
[ 0.000000] node 0: [mem 0x0000001fa7590000-0x0000001fa7dfffff]
Focus on the last memory range, and there is a hole for the range [mem
0x0000001fa7590000-0x0000001fa7dfffff]. That means the last pageblock
will contain the range from 0x1fa7c00000 to 0x1fa7ffffff, since the
pageblock must be 4M aligned. And in this pageblock, these pfns will fall
into 2 sub-section (the sub-section size is 2M aligned).
So, the 1st sub-section (indicates pfn range: 0x1fa7c00000 - 0x1fa7dfffff
) in this pageblock is valid by calling subsection_map_init() in
free_area_init(), but the 2nd sub-section (indicates pfn range:
0x1fa7e00000 - 0x1fa7ffffff ) in this pageblock is not valid.
This did not break anything until now, but the zone continuous is fragile
in this possible scenario. So as previous discussion[1], it is better to
add some comments to explain this possible issue in case there are some
future pfn walkers that rely on this.

Let's factor out actual disabling of KSM. The existing "mm->def_flags &=
~VM_MERGEABLE;" was essentially a NOP and can be dropped, because
def_flags should never include VM_MERGEABLE. Note that we don't currently
prevent re-enabling KSM.
This should now be faster in case KSM was never enabled, because we only
conditionally iterate all VMAs. Further, it certainly looks cleaner.

s390/gmap code.
This patch (of 3):
Let's unmerge any KSM pages when setting PR_SET_MEMORY_MERGE=0, and clear
the VM_MERGEABLE flag from all VMAs -- just like KSM would. Of course,
only do that if we previously set PR_SET_MEMORY_MERGE=1.

Core changes:
- Make a lot of pin controllers with GPIO and irqchips immutable,
i.e. not living structs, but const structs. This is driving a
changed initiated by the irqchip maintainers.
New drivers:
- New driver for the NXP S32 SoC pin controller
- As part of a thorough cleanup and restructuring of the
Ralink/Mediatek drivers, the Ralink MIPS pin control drivers
were folded into the Mediatek directory and the family is
renamed "mtmips". The Ralink chips live on as Mediatek MIPS
family where new variants can be added. As part of this work
also the device tree bindings were reworked.
- New subdriver for the Qualcomm SM7150 SoC.
- New subdriver for the Qualcomm IPQ9574 SoC.
- New driver for the nVidia BlueField-3 SoC.
- Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
- Support for the Qualcomm PMI632 mixed signal circuit GPIO.
Improvements:
- Add some missing pins and generic cleanups on the Renesas
r8a779g0 and r8a779g0 pin controllers. Generic Renesas
extension for power source selection on several SoCs.
- Misc cleanups for the Atmel AT91 and AT91-PIO4 pin
controllers
- Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi
driver.
- Several device tree binding cleanups as the binding
YAML syntax is solidifying.

Pull pin control updates from Linus Walleij:
"Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
the new NXP S32 and nVidia BlueField-3.
Core changes:
- Make a lot of pin controllers with GPIO and irqchips immutable,
i.e. not living structs, but const structs. This is driving a
changed initiated by the irqchip maintainers.
New drivers:
- New driver for the NXP S32 SoC pin controller
- As part of a thorough cleanup and restructuring of the
Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
folded into the Mediatek directory and the family is renamed
"mtmips". The Ralink chips live on as Mediatek MIPS family where
new variants can be added. As part of this work also the device
tree bindings were reworked.
- New subdriver for the Qualcomm SM7150 SoC.
- New subdriver for the Qualcomm IPQ9574 SoC.
- New driver for the nVidia BlueField-3 SoC.
- Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
- Support for the Qualcomm PMI632 mixed signal circuit GPIO.
Improvements:
- Add some missing pins and generic cleanups on the Renesas r8a779g0
and r8a779g0 pin controllers. Generic Renesas extension for power
source selection on several SoCs.
- Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers
- Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver.
- Several device tree binding cleanups as the binding YAML syntax is
solidifying"

Merge tag 'afs-fixes-20230502' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull AFS updates from David Howells:
"Three fixes to AFS directory handling:
- Make sure that afs_read_dir() sees any increase in file size if the
file unexpectedly changed on the server (e.g. due to another client
making a change).
- Make afs_getattr() always return the server's dir file size, not
the locally edited one, so that pagecache eviction doesn't cause
the dir file size to change unexpectedly.
- Prevent afs_read_dir() from getting into an endless loop if the
server indicates that the directory file size is larger than
expected"
