Introduce driver specific uapi functionalites. Added a alloc_page
functionality for user library to allocate specific pages. Currently added
support for allocating write combine pages for push functinality. This
interface shall be extended for other page allocations.
Allocate a WC page using the uapi hook for enabling the low latency push
in Gen P5 adapters for small packets. This is supported only for the user
space QPs.

Previously when destroying a DCT, if the firmware function for the
destruction failed, the common resource would have been destroyed
either way, since it was destroyed before the firmware object.
Which leads to kernel warning "refcount_t: underflow" which indicates
possible use-after-free.
Which is triggered when we try to destroy the common resource for the
second time and execute refcount_dec_and_test(&common->refcount).
So, let's fix the destruction order by factoring out the DCT QP logic
to be in separate XArray database.
refcount_t: underflow; use-after-free.

driver.h is common header to whole mlx5 code base, but struct
mlx5_qp_table is used in mlx5_ib driver only. So move that struct
to be under sole responsibility of mlx5_ib.

With RX coalescing, one CQE entry can be used to indicate multiple packets
on the receive queue. This saves processing time and PCI bandwidth over
the CQ.
The MANA Ethernet driver also uses the v2 version of the protocol. It
doesn't use RX coalescing and its behavior is not changed.

Before blamed commit, pskb_may_pull() was used instead
of skb_header_pointer() in __vlan_get_protocol() and friends.
Few callers depended on skb->head being populated with MAC header,
syzbot caught one of them (skb_mac_gso_segment())
Add vlan_get_protocol_and_depth() to make the intent clearer
and use it where sensible.
This is a more generic fix than commit e9d3f80935b6
("net/af_packet: make sure to pull mac header") which was
dealing with a similar issue.

Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3ce9
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.
ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000
To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.

As the nvme driver uses this helper, it causes a compilation issue:
drivers/nvme/host/ioctl.c: In function 'nvme_uring_cmd_io':
drivers/nvme/host/ioctl.c:555:44: error: implicit declaration of function 'io_uring_sqe_cmd'; did you mean 'io_uring_free'? [-Werror=implicit-function-declaration]
555 | const struct nvme_uring_cmd *cmd = io_uring_sqe_cmd(ioucmd->sqe);
| ^~~~~~~~~~~~~~~~
| io_uring_free
Fix it by just making io_uring_sqe_cmd() generally available - the types
are known, and there's no reason to hide it under CONFIG_IO_URING.

Commit
310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")
switched to using amd_smn_read() which relies upon the misc PCI ID used
by DF function 3 being included in a table. The ID for model 78h is
missing in that table, so amd_smn_read() doesn't work.
Add the missing ID into amd_nb, restoring s2idle on this system.
[ bp: Simplify commit message. ]

Pull more tracing updates from Steven Rostedt:
- Make buffer_percent read/write.
The buffer_percent file is how users can state how long to block on
the tracing buffer depending on how much is in the buffer. When it
hits the "buffer_percent" it will wake the task waiting on the
buffer. For some reason it was set to read-only.
This was not noticed because testing was done as root without
SELinux, but with SELinux it will prevent even root to write to it
without having CAP_DAC_OVERRIDE.
- The "touched_functions" was added this merge window, but one of the
reasons for adding it was not implemented.
That was to show what functions were not only touched, but had either
a direct trampoline attached to it, or a kprobe or live kernel
patching that can "hijack" the function to run a different function.
The point is to know if there's functions in the kernel that may not
be behaving as the kernel code shows. This can be used for debugging.
TODO: Add this information to kernel oops too.

If a function had ever had IPMODIFY or DIRECT attached to it, where this
is how live kernel patching and BPF overrides work, mark them and display
an "M" in the enabled_functions and touched_functions files. This can be
used for debugging. If a function had been modified and later there's a bug
in the code related to that function, this can be used to know if the cause
is possibly from a live kernel patch or a BPF program that changed the
behavior of the code.
Also update the documentation on the enabled_functions and
touched_functions output, as it was missing direct callers and CALL_OPS.
And include this new modify attribute.

Currently uring CMD operation relies on having large SQEs, but future
operations might want to use normal SQE.
The io_uring_cmd currently only saves the payload (cmd) part of the SQE,
but, for commands that use normal SQE size, it might be necessary to
access the initial SQE fields outside of the payload/cmd block. So,
saves the whole SQE other than just the pdu.
This changes slightly how the io_uring_cmd works, since the cmd
structures and callbacks are not opaque to io_uring anymore. I.e, the
callbacks can look at the SQE entries, not only, in the cmd structure.
The main advantage is that we don't need to create custom structures for
simple commands.
Creates io_uring_sqe_cmd() that returns the cmd private data as a null
pointer and avoids casting in the callee side.
Also, make most of ublk_drv's sqe->cmd priv structure into const, and use
io_uring_sqe_cmd() to get the private structure, removing the unwanted
cast. (There is one case where the cast is still needed since the
header->{len,addr} is updated in the private structure)

The gxp_i2c_slave_irq_handler() is hidden in an #ifdef, but the
caller uses an IS_ENABLED() check:
drivers/i2c/busses/i2c-gxp.c: In function 'gxp_i2c_irq_handler':
drivers/i2c/busses/i2c-gxp.c:467:29: error: implicit declaration of function 'gxp_i2c_slave_irq_handler'; did you mean 'gxp_i2c_irq_handler'? [-Werror=implicit-function-declaration]
It has to consistently use one method or the other to avoid warnings,
so move to IS_ENABLED() here for readability and build coverage, and
move the #ifdef in linux/i2c.h to allow building it as dead code.

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.

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.

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.

Patch series "mm/ksm: improve PR_SET_MEMORY_MERGE=0 handling and cleanup
disabling KSM", v2.
(1) Make PR_SET_MEMORY_MERGE=0 unmerge pages like setting MADV_UNMERGEABLE
does, (2) add a selftest for it and (3) factor out disabling of KSM from
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.

Pull kvm updates from Paolo Bonzini:
"s390:
- More phys_to_virt conversions
- Improvement of AP management for VSIE (nested virtualization)
ARM64:
- Numerous fixes for the pathological lock inversion issue that
plagued KVM/arm64 since... forever.
- New framework allowing SMCCC-compliant hypercalls to be forwarded
to userspace, hopefully paving the way for some more features being
moved to VMMs rather than be implemented in the kernel.
- Large rework of the timer code to allow a VM-wide offset to be
applied to both virtual and physical counters as well as a
per-timer, per-vcpu offset that complements the global one. This
last part allows the NV timer code to be implemented on top.
- A small set of fixes to make sure that we don't change anything
affecting the EL1&0 translation regime just after having having
taken an exception to EL2 until we have executed a DSB. This
ensures that speculative walks started in EL1&0 have completed.
- The usual selftest fixes and improvements.
x86:
- Optimize CR0.WP toggling by avoiding an MMU reload when TDP is
enabled, and by giving the guest control of CR0.WP when EPT is
enabled on VMX (VMX-only because SVM doesn't support per-bit
controls)
- Add CR0/CR4 helpers to query single bits, and clean up related code
where KVM was interpreting kvm_read_cr4_bits()'s "unsigned long"
return as a bool
- Move AMD_PSFD to cpufeatures.h and purge KVM's definition
- Avoid unnecessary writes+flushes when the guest is only adding new
PTEs
- Overhaul .sync_page() and .invlpg() to utilize .sync_page()'s
optimizations when emulating invalidations
- Clean up the range-based flushing APIs
- Revamp the TDP MMU's reaping of Accessed/Dirty bits to clear a
single A/D bit using a LOCK AND instead of XCHG, and skip all of
the "handle changed SPTE" overhead associated with writing the
entire entry
- Track the number of "tail" entries in a pte_list_desc to avoid
having to walk (potentially) all descriptors during insertion and
deletion, which gets quite expensive if the guest is spamming
fork()
- Disallow virtualizing legacy LBRs if architectural LBRs are
available, the two are mutually exclusive in hardware
- Disallow writes to immutable feature MSRs (notably
PERF_CAPABILITIES) after KVM_RUN, similar to CPUID features
- Overhaul the vmx_pmu_caps selftest to better validate
PERF_CAPABILITIES
- Apply PMU filters to emulated events and add test coverage to the
pmu_event_filter selftest
- AMD SVM:
- Add support for virtual NMIs
- Fixes for edge cases related to virtual interrupts
- Intel AMX:
- Don't advertise XTILE_CFG in KVM_GET_SUPPORTED_CPUID if
XTILE_DATA is not being reported due to userspace not opting in
via prctl()
- Fix a bug in emulation of ENCLS in compatibility mode
- Allow emulation of NOP and PAUSE for L2
- AMX selftests improvements
- Misc cleanups
MIPS:
- Constify MIPS's internal callbacks (a leftover from the hardware
enabling rework that landed in 6.3)
Generic:
- Drop unnecessary casts from "void *" throughout kvm_main.c
- Tweak the layout of "struct kvm_mmu_memory_cache" to shrink the
struct size by 8 bytes on 64-bit kernels by utilizing a padding
hole

but that starts the call timer so the call timer might then expire before
we get a connection assigned - leading to the following oops if the call
stalled:
BUG: kernel NULL pointer dereference, address: 0000000000000000

Fix this by noting the timeouts in struct rxrpc_call when the call is
created. The timer will be started when the first packet is transmitted.
It shouldn't be possible to trigger this directly from userspace through
AF_RXRPC as sendmsg() will return EBUSY if the call is in the
waiting-for-conn state if it dropped out of the wait due to a signal.
