Chuck run into an issue with a single-element attr-set which
only has an attr with value of 0. The search for max attr in
a struct records attrs with value larger than 0 only (max_val
is set to 0 at the start). Adjust the comparison, alternatively
max_val could be init'ed to -1. Somehow picking the last attr
of a value seems like a good idea in general.

Fix the cifs_writepages_region() to just jump over members of the batch
that have been cleaned up rather than counting them as skipped.
Unlike the other "skip_write" cases, this situation happens even for
WB_SYNC_ALL, simply because the page has either been cleaned by somebody
else, or was truncated.
So in this case we're not "skipping" the write, we simply no longer need
any write at all, so it's very different from the other skip_write cases.
And we definitely shouldn't stop writing the rest just because of too
many of these cases (or because we want to be rescheduled).

Currently, during the early stages of their unloading, particularly
during SRIOV disablement, PFs/ECPFs wait on the release of all of
their VFs memory pages. Furthermore, ECPFs are considered the page
supplier for host VFs, hence the host VFs memory pages are freed only
during ECPF cleanup when host interfaces get disabled.
Thus, disabling SRIOV early in unload timeline causes the DPU ECPF
to stall on driver unload while waiting on the release of host VF pages
that won't be freed before host interfaces get disabled later on.
Therefore, for ECPFs, wait on the release of VFs pages only after the
disablement of host PFs during ECPF cleanup flow. Then, host PFs and VFs
are disabled and their memory shall be freed accordingly.

Fifo indexes are not checked during pop operations and it leads to
potential use-after-free when poping from empty queue. Such case was
possible during re-sync action. WARN_ON_ONCE covers future cases.
There were out-of-order cqe spotted which lead to drain of the queue and
use-after-free because of lack of fifo pointers check. Special check and
counter are added to avoid resync operation if SKB could not exist in the
fifo because of OOO cqe (skb_id must be between consumer and producer

During ptp resync operation SKBs were poped from the fifo but were never
freed neither by napi_consume nor by dev_kfree_skb_any. Add call to
napi_consume_skb to properly free SKBs.
Another leak was happening because mlx5e_skb_fifo_has_room() had an error
in the check. Comparing free running counters works well unless C promotes
the types to something wider than the counter. In this case counters are
u16 but the result of the substraction is promouted to int and it causes
wrong result (negative value) of the check when producer have already
overlapped but consumer haven't yet. Explicit cast to u16 fixes the issue.

Fix the reset sequence of reads and writes that we invoke from within
the early trigger. It looks like there never was a SERDES_CONF_SOME_RST
bit that should be involved in the reset sequence, and its presence in
the driver code is a mistake from earlier.
Instead, the reset sequence should go as follows: We should switch the
the SERDES unit's SYNC_SEL mux to the value of 7 (so outside the range
of 1...6 representing cluster's SYNCGEN units), then raise the RST bit
in SERDES_STATUS and wait for it to clear.
Properly resetting the SERDES unit fixes frame desynchronization hazard
in case of long frames (longer than 4 used slots). The desynchronization
manifests itself by rotating the PCM channels.

Revert the HUGETLB_PAGE_FREE_VMEMMAP selection from commit 1e63ac088f
("arm64: mm: hugetlb: enable HUGETLB_PAGE_FREE_VMEMMAP for arm64") but
keep the flush_dcache_page() compound_head() change as it aligns with
the corresponding check in the __sync_icache_dcache() function.
The original config option was renamed in commit 47010c040d ("mm:
hugetlb_vmemmap: cleanup CONFIG_HUGETLB_PAGE_FREE_VMEMMAP*") to
HUGETLB_PAGE_OPTIMIZE_VMEMMAP and the flush_dcache_page() check was
further simplified by commit 2da1c30929 ("mm: hugetlb_vmemmap: delete
hugetlb_optimize_vmemmap_enabled()").
The reason for the revert is that the generic vmemmap_remap_pte()
function changes both the permissions (writeable to read-only) and the
output address (pfn) of the vmemmap ptes. This is deemed UNPREDICTABLE
by the Arm architecture without a break-before-make sequence (make the
PTE invalid, TLBI, write the new valid PTE). However, such sequence is
not possible since the vmemmap may be concurrently accessed by the
kernel. Disable the optimisation until a better solution is found.

Today the connection sequence of the Xen 9pfs frontend doesn't match
the documented sequence. It can work reliably only for a PV 9pfs device
having been added at boot time already, as the frontend is not waiting
for the backend to have set its state to "XenbusStateInitWait" before
reading the backend properties from Xenstore.
Fix that by following the documented sequence [1] (the documentation
has a bug, so the reference is for the patch fixing that).

When connecting the Xen 9pfs frontend to the backend, the "versions"
Xenstore entry written by the backend is parsed in a wrong way.
The "versions" entry is defined to contain the versions supported by
the backend separated by commas (e.g. "1,2"). Today only version "1"
is defined. Unfortunately the frontend doesn't look for "1" being
listed in the entry, but it is expecting the entry to have the value
"1".
This will result in failure as soon as the backend will support e.g.
versions "1" and "2".
Fix that by scanning the entry correctly.

/proc/kcore better represent the real state of things in his series
"mm/vmalloc.c: allow vread() to read out vm_map_ram areas".
- Jason Gunthorpe rationalized the GUP system's interface to the rest
of the kernel in the series "Simplify the external interface for
GUP".
- SeongJae Park wishes to migrate people from DAMON's debugfs interface
over to its sysfs interface. To support this, we'll temporarily be
printing warnings when people use the debugfs interface. See the

Each probe has an instance of process_fetch_insn respectively,
but they have something in common.
This patch aims to extract the common part into
process_common_fetch_insn which can be shared by each probe,
and they only need to focus on their special cases.

There are 6 function definitions in trace_probe_tmpl.h, they are:
1, fetch_store_strlen
2, fetch_store_string
3, fetch_store_strlen_user
4, fetch_store_string_user
5, probe_mem_read
6, probe_mem_read_user
Every C file which includes trace_probe_tmpl.h has to implement them,
otherwise it gets warnings and errors. However, some of them are identical,
like kprobe and eprobe, as a result, there is a lot redundant code in those
2 files.
This patch would like to provide default behaviors for those functions
which kprobe and eprobe can share by just including trace_probe_kernel.h
with trace_probe_tmpl.h together.
It removes redundant code, increases readability, and more importantly,
makes it easier to introduce a new feature based on trace probe
(it's possible).

print_probe_args is currently inplemented in trace_probe_tmpl.h and
included by *probes, as a result, each probe has an identical copy.
This patch will move it to trace_probe.c as an new API, each probe
calls it to print their args in trace file.

This adds support for the 256-byte internal RAM. There are two windows
which can be used to access this RAM: 64 bytes at 0x40 (the "standard"
address space) and 128 bytes at 0x80 (the "alternate" address space). We
use the standard address space because it is also accessible over SPI
(if such a port is ever done). We are limited to 32-byte reads for SMBus
compatibility, so there's no advantage to using the alternate address
space.
There are some reserved bits in the EXTRAM register, and the datasheet
doesn't say what to do with them. I've opted to skip a read/modify/write
and just write the whole thing. If this driver is ever converted to
regmap, this would be a good place to use regmap_update_bits.
