When pages are removed in rb_remove_pages(), 'cpu_buffer->read' is set
to 0 in order to make sure any read iterators reset themselves. However,
this will mess 'entries' stating, see following steps:
# cd /sys/kernel/tracing/
# 1. Enlarge ring buffer prepare for later reducing:
# echo 20 > per_cpu/cpu0/buffer_size_kb
# 2. Write a log into ring buffer of cpu0:
# taskset -c 0 echo "hello1" > trace_marker
# 3. Read the log:
# cat per_cpu/cpu0/trace_pipe
<...>-332 [000] ..... 62.406844: tracing_mark_write: hello1
# 4. Stop reading and see the stats, now 0 entries, and 1 event readed:
# cat per_cpu/cpu0/stats
entries: 0
[...]
read events: 1
# 5. Reduce the ring buffer
# echo 7 > per_cpu/cpu0/buffer_size_kb
# 6. Now entries became unexpected 1 because actually no entries!!!
# cat per_cpu/cpu0/stats
entries: 1
[...]
read events: 0
To fix it, introduce 'page_removed' field to count total removed pages
since last reset, then use it to let read iterators reset themselves
instead of changing the 'read' pointer.

recv_data either returns the number of received bytes, or a negative value
representing an error code. Adding the return value directly to the total
number of received bytes therefore looks a little weird, since it might add
a negative error code to a sum of bytes.
The following check for size < expected usually makes the function return
ETIME in that case, so it does not cause too many problems in practice. But
to make the code look cleaner and because the caller might still be
interested in the original error code, explicitly check for the presence of
an error code and pass that through.

several of them were from inspection while hunting down a couple of
regressions.
The most important one to pull is 75b396821c

which caused a regression for some folks by restricting mmap
in any case where writeback caches weren't enabled.
Most of the other bugs caught via inspection were type mismatches.

Pull 9p fixes from Eric Van Hensbergen:
"Misc set of fixes for 9p.
Most of these clean up warnings we've gotten out of compilation tools,
but several of them were from inspection while hunting down a couple
of regressions.
The most important one is 75b396821c ("fs/9p: remove unnecessary and
overrestrictive check") which caused a regression for some folks by
restricting mmap in any case where writeback caches weren't enabled.
Most of the other bugs caught via inspection were type mismatches"

This reverts commit 9e46e4dcd9.
kbuild reports a warning in memblock_remove_region() because of a false
positive caused by partial reset of the memblock state.
Doing the full reset will remove the false positives, but will allow
late use of memblock_free() to go unnoticed, so it is better to revert
the offending commit.

mbind() calls down into vma_replace_policy() without taking the per-VMA
locks, replaces the VMA's vma->vm_policy pointer, and frees the old
policy. That's bad; a concurrent page fault might still be using the
old policy (in vma_alloc_folio()), resulting in use-after-free.
Normally this will manifest as a use-after-free read first, but it can
result in memory corruption, including because vma_alloc_folio() can
call mpol_cond_put() on the freed policy, which conditionally changes
the policy's refcount member.
This bug is specific to CONFIG_NUMA, but it does also affect non-NUMA
systems as long as the kernel was built with CONFIG_NUMA.

According to the ARM IORT specifications DEN 0049 issue E,
the "Number of IDs" field in the ID mapping format reports
the number of IDs in the mapping range minus one.
In iort_node_get_rmr_info(), we erroneously skip ID mappings
whose "Number of IDs" equal to 0, resulting in valid mapping
nodes with a single ID to map being skipped, which is wrong.
Fix iort_node_get_rmr_info() by removing the bogus id_count
check.

With ppc64 -mprofile-kernel and ppc32 -pg, profiling instructions to
call into ftrace are emitted right at function entry. The instruction
sequence used is minimal to reduce overhead. Crucially, a stackframe is
not created for the function being traced. This breaks stack unwinding
since the function being traced does not have a stackframe for itself.
As such, it never shows up in the backtrace:
/sys/kernel/debug/tracing # echo 1 > /proc/sys/kernel/stack_tracer_enabled
/sys/kernel/debug/tracing # cat stack_trace

Fix this by having ftrace create a dummy stackframe for the function

As the code comment says, the initial aim is to reduce one instruction
in some corner cases, if bit[51:31] is all 0 or all 1, no need to call
lu32id. That is to say, it should call lu32id only if bit[51:31] is not
all 0 and not all 1. The current code always call lu32id, the result is
right but the logic is unexpected and wrong, fix it.

Currently nettrace does not work on LoongArch due to missing
bpf_probe_read{,str}() support, with the error message:
ERROR: failed to load kprobe-based eBPF
ERROR: failed to load kprobe-based bpf
According to commit 0ebeea8ca8 ("bpf: Restrict bpf_probe_read{,
str}() only to archs where they work"), we only need to select
CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE to add said support,
because LoongArch does have non-overlapping address ranges for kernel
and userspace.

Binutils 2.41 enables linker relaxation by default, but the kernel
module loader doesn't support that, so just disable it. Otherwise we
get such an error when loading modules:
"Unknown relocation type 102"
As an alternative, we could add linker relaxation support in the kernel
module loader. But it is relatively large complexity that may or may not
bring a similar gain, and we don't really want to include this linker
pass in the kernel.

This is a port of commit 4fe4a6374c ("MIPS: Only fiddle with
CHECKFLAGS if `need-compiler'") to LoongArch.
We have originally guarded fiddling with CHECKFLAGS in our arch Makefile
by checking for the CONFIG_LOONGARCH variable, not set for targets such
as `distclean', etc. that neither include `.config' nor use the compiler.
Starting from commit 805b2e1d42 ("kbuild: include Makefile.compiler
only when compiler is needed") we have had a generic `need-compiler'
variable explicitly telling us if the compiler will be used and thus its
capabilities need to be checked and expressed in the form of compilation
flags. If this variable is not set, then `make' functions such as
`cc-option' are undefined, causing all kinds of weirdness to happen if
we expect specific results to be returned.
It doesn't cause problems on LoongArch now. But as a guard we replace
the check for CONFIG_LOONGARCH with one for `need-compiler' instead, so
as to prevent the compiler from being ever called for CHECKFLAGS when
not needed.

The condition to fetch sense data was supposed to be:
ATA_SENSE set AND either
1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag
ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command
sense data supported bit is set); or
2) Command was non-NCQ and regular sense data reporting is enabled.
However the check in 2) accidentally had the negation at the wrong place,
causing it to try to fetch sense data if it was a non-NCQ command _or_
if regular sense data reporting was _not_ enabled.
Fix this by removing the extra parentheses that should not be there,
such that only the correct return (ata_is_ncq()) is negated.
