Pull x86 fixes from Thomas Gleixner:
- x2apic_disable() clears x2apic_state and x2apic_mode unconditionally,
even when the state is X2APIC_ON_LOCKED, which prevents the kernel to
disable it thereby creating inconsistent state.
Reorder the logic so it actually works correctly
- The XSTATE logic for handling LBR is incorrect as it assumes that
XSAVES supports LBR when the CPU supports LBR. In fact both
conditions need to be true. Otherwise the enablement of LBR in the
IA32_XSS MSR fails and subsequently the machine crashes on the next
XRSTORS operation because IA32_XSS is not initialized.
Cache the XSTATE support bit during init and make the related
functions use this cached information and the LBR CPU feature bit to
cure this.
- Cure a long standing bug in KASLR
KASLR uses the full address space between PAGE_OFFSET and vaddr_end
to randomize the starting points of the direct map, vmalloc and
vmemmap regions. It thereby limits the size of the direct map by
using the installed memory size plus an extra configurable margin for
hot-plug memory. This limitation is done to gain more randomization
space because otherwise only the holes between the direct map,
vmalloc, vmemmap and vaddr_end would be usable for randomizing.
The limited direct map size is not exposed to the rest of the kernel,
so the memory hot-plug and resource management related code paths
still operate under the assumption that the available address space
can be determined with MAX_PHYSMEM_BITS.
request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1
downwards. That means the first allocation happens past the end of
the direct map and if unlucky this address is in the vmalloc space,
which causes high_memory to become greater than VMALLOC_START and
consequently causes iounmap() to fail for valid ioremap addresses.
Cure this by exposing the end of the direct map via PHYSMEM_END and
use that for the memory hot-plug and resource management related
places instead of relying on MAX_PHYSMEM_BITS. In the KASLR case
PHYSMEM_END maps to a variable which is initialized by the KASLR
initialization and otherwise it is based on MAX_PHYSMEM_BITS as
before.
- Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of
an initialized variabled on the stack to the VMM. The variable is
only required as output value, so it does not have to exposed to the
VMM in the first place.
- Prevent an array overrun in the resource control code on systems with
Sub-NUMA Clustering enabled because the code failed to adjust the
index by the number of SNC nodes per L3 cache.

Pull irq fixes from Thomas Gleixner:
"A set of fixes for interrupt chip drivers:
- Unbreak the PLIC driver for Allwinner D1 systems
The recent conversion of the PLIC driver to a platform driver broke
Allwinnder D1 systems due to the deferred probing of platform
drivers.
Due to that the only timer available on D1 systems cannot get an
interrupt, which causes the system to hang at boot. Other RISCV
platforms are not affected because they provide the architected SBI
timer which uses the built in core interrupt controller.
Cure this by probing PLIC early on D1 systems
- Cure a regression in ARM/GIC-V3 on 32-bit ARM systems caused by the
recent addition of a initialization function, which accesses system
registers before they are enabled. On 64-bit ARM they are enabled
prior to that by sheer luck.
Ensure they are enabled.
- Cure a use before check problem in the MSI library. The existing
NULL pointer check is too late.
- Cure a lock order inversion in the ARM/GIC-V4 driver
- Fix a IS_ERR() vs. NULL pointer check issue in the RISCV APLIC
driver

errors that are known to always be safe to fix should be autofix: this
should be most errors even at this point, but that will need some
thorough review.
note that errors are still logged in the superblock, so we'll still know

We had a report of data corruption on nixos when building installer
images.
https://github.com/NixOS/nixpkgs/pull/321055#issuecomment-2184131334
It seems that writes are being dropped, but only when issued by QEMU,
and possibly only in snapshot mode. It's undetermined if it's write
calls are being dropped or dirty folios.
Further testing, via minimizing the original patch to just the change
that skips the inode lock on non appends/truncates, reveals that it
really is just not taking the inode lock that causes the corruption: it
has nothing to do with the other logic changes for preserving write
atomicity in corner cases.
It's also kernel config dependent: it doesn't reproduce with the minimal
kernel config that ktest uses, but it does reproduce with nixos's distro
config. Bisection the kernel config initially pointer the finger at page
migration or compaction, but it appears that was erroneous; we haven't
yet determined what kernel config option actually triggers it.
Sadly it appears this will have to be reverted since we're getting too
close to release and my plate is full, but we'd _really_ like to fully
debug it.
My suspicion is that this patch is exposing a preexisting bug - the
inode lock actually covers very little in IO paths, and we have a
different lock (the pagecache add lock) that guards against races with
truncate here.

io_provided_buffers_select() returns 0 to indicate success, but it should
be returning 1 to indicate that 1 vec was mapped. This causes peeking
to fail with classic provided buffers, and while that's not a use case
that anyone should use, it should still work correctly.
The end result is that no buffer will be selected, and hence a completion
with '0' as the result will be posted, without a buffer attached.

It is not safe to dereference fl->c.flc_owner without first confirming
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()
tests fl_lmops but largely ignores the result and assumes that flc_owner
is an nfs4_delegation anyway. This is wrong.
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave
as it did before the change mentioned below. This is the same as the
current code, but without any reference to a possible delegation.

For buffer registration (or updates), a userspace iovec is copied in
and updated. If the application is within a compat syscall, then the
iovec type is compat_iovec rather than iovec. However, the type used
in __io_sqe_buffers_update() and io_sqe_buffers_register() is always
struct iovec, and hence the source is incremented by the size of a
non-compat iovec in the loop. This misses every other iovec in the
source, and will run into garbage half way through the copies and
return -EFAULT to the application.
Maintain the source address separately and assign to our user vec
pointer, so that copies always happen from the right source address.
While in there, correct a bad placement of __user which triggered
the following sparse warning prior to this fix:
io_uring/rsrc.c:981:33: warning: cast removes address space '__user' of expression
io_uring/rsrc.c:981:30: warning: incorrect type in assignment (different address spaces)

- handle non-VGA devices bettter
amdgpu:
- SWSMU gaming stability fix
- SMU 13.0.7 fix
- SWSMU documentation alignment fix
- SMU 14.0.x fixes

The runtime constant feature removes all the users of these variables,
allowing the compiler to optimize them away. It's quite difficult to
extract their values from the kernel text, and the memory saved by
removing them is tiny, and it was never the point of this optimization.
Since the dentry_hashtable is a core data structure, it's valuable for
debugging tools to be able to read it easily. For instance, scripts
built on drgn, like the dentrycache script[1], rely on it to be able to
perform diagnostics on the contents of the dcache. Annotate it as used,
so the compiler doesn't discard it.

Commit 8bccf667f62a ("Input: cypress_ps2 - report timeouts when reading
command status") uncovered an existing problem with cypress_ps2 driver:
it tries waiting on a PS/2 device waitqueue without using the rest of
libps2. Unfortunately without it nobody signals wakeup for the
waiting process, and each "extended" command was timing out. But the
rest of the code simply did not notice it.
Fix this by switching from homegrown way of sending request to get
command response and reading it to standard ps2_command() which does
the right thing.

In case of im_protocols value is 1 and tm_protocols value is 0 this
combination successfully passes the check
'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
But then after pn533_poll_create_mod_list() call in pn533_start_poll()
poll mod list will remain empty and dev->poll_mod_count will remain 0
which lead to division by zero.
Normally no im protocol has value 1 in the mask, so this combination is
not expected by driver. But these protocol values actually come from
userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
broken or malicious program may pass a message containing a "bad"
combination of protocol parameter values so that dev->poll_mod_count
is not incremented inside pn533_poll_create_mod_list(), thus leading
to division by zero.
Call trace looks like:
nfc_genl_start_poll()
nfc_start_poll()
->start_poll()
pn533_start_poll()
Add poll mod list filling check.

Patch #1 sets on NFT_PKTINFO_L4PROTO for UDP packets less than 4 bytes
payload from netdev/egress by subtracting skb_network_offset() when

====================
mptcp: more fixes for the in-kernel PM
Here is a new batch of fixes for the MPTCP in-kernel path-manager:
Patch 1 ensures the address ID is set to 0 when the path-manager sends
an ADD_ADDR for the address of the initial subflow. The same fix is
applied when a new subflow is created re-using this special address. A
fix for v6.0.
Patch 2 is similar, but for the case where an endpoint is removed: if
this endpoint was used for the initial address, it is important to send
a RM_ADDR with this ID set to 0, and look for existing subflows with the
ID set to 0. A fix for v6.0 as well.
Patch 3 validates the two previous patches.
Patch 4 makes the PM selecting an "active" path to send an address
notification in an ACK, instead of taking the first path in the list. A
fix for v5.11.
Patch 5 fixes skipping the establishment of a new subflow if a previous
subflow using the same pair of addresses is being closed. A fix for
v5.13.
Patch 6 resets the ID linked to the initial subflow when the linked
endpoint is re-added, possibly with a different ID. A fix for v6.0.
Patch 7 validates the three previous patches.
Patch 8 is a small fix for the MPTCP Join selftest, when being used with
older subflows not supporting all MIB counters. A fix for a commit
introduced in v6.4, but backported up to v5.10.
Patch 9 avoids the PM to try to close the initial subflow multiple
times, and increment counters while nothing happened. A fix for v5.10.
Patch 10 stops incrementing local_addr_used and add_addr_accepted
counters when dealing with the address ID 0, because these counters are
not taking into account the initial subflow, and are then not
decremented when the linked addresses are removed. A fix for v6.0.
Patch 11 validates the previous patch.
Patch 12 avoids the PM to send multiple SUB_CLOSED events for the
initial subflow. A fix for v5.12.
Patch 13 validates the previous patch.
Patch 14 stops treating the ADD_ADDR 0 as a new address, and accepts it
in order to re-create the initial subflow if it has been closed, even if
the limit for *new* addresses -- not taking into account the address of
the initial subflow -- has been reached. A fix for v5.10.
Patch 15 validates the previous patch.

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

The ADD_ADDR 0 with the address from the initial subflow should not be
considered as a new address: this is not something new. If the host
receives it, it simply means that the address is available again.
When receiving an ADD_ADDR for the ID 0, the PM already doesn't consider
it as new by not incrementing the 'add_addr_accepted' counter. But the
'accept_addr' might not be set if the limit has already been reached:
this can be bypassed in this case. But before, it is important to check
that this ADD_ADDR for the ID 0 is for the same address as the initial
subflow. If not, it is not something that should happen, and the
ADD_ADDR can be ignored.
Note that if an ADD_ADDR is received while there is already a subflow
opened using the same address, this ADD_ADDR is ignored as well. It
means that if multiple ADD_ADDR for ID 0 are received, there will not be
any duplicated subflows created by the client.

This test extends "delete and re-add" and "delete re-add signal" to

A new helper has been introduced to easily check these events. The
missing events have been added to the lib.
