CONFIG_UPROBES is enabled by CONFIG_UPROBE_EVENTS, which gets enabled by
CONFIG_FTRACE. Therefore add these configs to selftests/mm/config so that
CI systems can include this config in the kernel build. To be completely
safe, add CONFIG_PROFILING too, to enable the dependency chain
PROFILING -> PERF_EVENTS -> UPROBE_EVENTS -> UPROBES.

The mm selftests are timing out with the current 180-second limit.
Testing shows that run_vmtests.sh takes approximately 11 minutes
(664 seconds) to complete.
Increase the timeout to 900 seconds (15 minutes) to provide sufficient
buffer for the tests to complete successfully.

BPF_MAP_TYPE_LRU_HASH can recycle most recent elements well before the
map is full, due to percpu reservations and force shrink before
neighbor stealing. Once a CPU is unable to borrow from the global map,
it will once steal one elem from a neighbor and after that each time
flush this one element to the global list and immediately recycle it.
Batch value LOCAL_FREE_TARGET (128) will exhaust a 10K element map
with 79 CPUs. CPU 79 will observe this behavior even while its
neighbors hold 78 * 127 + 1 * 15 == 9921 free elements (99%).
CPUs need not be active concurrently. The issue can appear with
affinity migration, e.g., irqbalance. Each CPU can reserve and then
hold onto its 128 elements indefinitely.
Avoid global list exhaustion by limiting aggregate percpu caches to
half of map size, by adjusting LOCAL_FREE_TARGET based on cpu count.
This change has no effect on sufficiently large tables.
Similar to LOCAL_NR_SCANS and lru->nr_scans, introduce a map variable
lru->free_target. The extra field fits in a hole in struct bpf_lru.
The cacheline is already warm where read in the hot path. The field is
only accessed with the lru lock held.

Since commit c84bf6dd2b83 ("mm: introduce new .mmap_prepare() file
callback"), the f_op->mmap() hook has been deprecated in favour of
f_op->mmap_prepare().
Additionally, commit bb666b7c2707 ("mm: add mmap_prepare() compatibility
layer for nested file systems") permits the use of the .mmap_prepare() hook
even in nested filesystems like overlayfs.
There are a number of places where we check only for f_op->mmap - this is
incorrect now mmap_prepare exists, so update all of these to use the
general helper can_mmap_file().
Most notably, this updates the elf logic to allow for the ability to
execute binaries on filesystems which have the .mmap_prepare hook, but
additionally we update nested filesystems.

The call_mmap() function violates the existing convention in
include/linux/fs.h whereby invocations of virtual file system hooks is
performed by functions prefixed with vfs_xxx().
Correct this by renaming call_mmap() to vfs_mmap(). This also avoids
confusion as to the fact that f_op->mmap_prepare may be invoked here.
Also rename __call_mmap_prepare() function to vfs_mmap_prepare() and adjust
to accept a file parameter, this is useful later for nested file systems.
Finally, fix up the VMA userland tests and ensure the mmap_prepare -> mmap
shim is implemented there.

Pull x86 fixes from Dave Hansen:
"This is a pretty scattered set of fixes. The majority of them are
further fixups around the recent ITS mitigations.
The rest don't really have a coherent story:
- Some flavors of Xen PV guests don't support large pages, but the
set_memory.c code assumes all CPUs support them.
Avoid problems with a quick CPU feature check.
- The TDX code has some wrappers to help retry calls to the TDX
module. They use function pointers to assembly functions and the
compiler usually generates direct CALLs. But some new compilers,
plus -Os turned them in to indirect CALLs and the assembly code was
not annotated for indirect calls.
Force inlining of the helper to fix it up.
- Last, a FRED issue showed up when single-stepping. It's fine when
using an external debugger, but was getting stuck returning from a
SIGTRAP handler otherwise.
Clear the FRED 'swevent' bit to ensure that forward progress is

Successful syscalls don't change errno, so checking errno is wrong
to ensure that a syscall has failed. For example for the following
sequence:
prctl(PR_SET_SYSCALL_USER_DISPATCH, op, 0x0, 0xff, 0);
EXPECT_EQ(EINVAL, errno);
prctl(PR_SET_SYSCALL_USER_DISPATCH, op, 0x0, 0x0, &sel);
EXPECT_EQ(EINVAL, errno);
only the first syscall may fail and set errno, but the second may succeed
and keep errno intact, and the check will falsely pass.
Or if errno happened to be EINVAL before, even the first check may falsely
pass.
Also use EXPECT/ASSERT consistently. Currently there is an inconsistent mix
without obvious reasons for usage of one or another.

Nested file systems, that is those which invoke call_mmap() within their
own f_op->mmap() handlers, may encounter underlying file systems which
provide the f_op->mmap_prepare() hook introduced by commit c84bf6dd2b83
("mm: introduce new .mmap_prepare() file callback").
We have a chicken-and-egg scenario here - until all file systems are
converted to using .mmap_prepare(), we cannot convert these nested
handlers, as we can't call f_op->mmap from an .mmap_prepare() hook.
So we have to do it the other way round - invoke the .mmap_prepare() hook
from an .mmap() one.
in order to do so, we need to convert VMA state into a struct vm_area_desc
descriptor, invoking the underlying file system's f_op->mmap_prepare()
callback passing a pointer to this, and then setting VMA state accordingly
and safely.
This patch achieves this via the compat_vma_mmap_prepare() function, which
we invoke from call_mmap() if f_op->mmap_prepare() is specified in the
passed in file pointer.
We place the fundamental logic into mm/vma.h where VMA manipulation
belongs. We also update the VMA userland tests to accommodate the
changes.
The compat_vma_mmap_prepare() function and its associated machinery is
temporary, and will be removed once the conversion of file systems is
complete.
We carefully place this code so it can be used with CONFIG_MMU and also
with cutting edge nommu silicon.

The test creates two ntuple rules with explicit location priorities:
- A high-priority rule (loc 0) directing specific port traffic to
context 0.
- A low-priority rule (loc 1) directing all other TCP traffic to context
1.
This validates that:
1. Rules targeting the default context function properly.
2. Traffic steering works as expected when mixing default and
additional RSS contexts.
The test was written by AI, and reviewed by humans.

KVM/arm64 fixes for 6.16, take #2
- Rework of system register accessors for system registers that are
directly writen to memory, so that sanitisation of the in-memory
value happens at the correct time (after the read, or before the
write). For convenience, RMW-style accessors are also provided.
- Multiple fixes for the so-called "arch-timer-edge-cases' selftest,
which was always broken.

nolibc only supports symbol-based stackprotectors, based on the global
variable __stack_chk_guard. Support for this differs between
architectures and toolchains. Some use the symbol mode by default, some
require a flag to enable it and some don't support it at all.
Before the nolibc test Makefile required the availability of
"-mstack-protector-guard=global" to enable stackprotectors.
While this flag makes sure that the correct mode is available it doesn't
work where the correct mode is the only supported one and therefore the
flag is not implemented.
Switch to a more dynamic probing mechanism.
This correctly enables stack protectors for mips, loongarch and m68k.

When FRED is enabled, if the Trap Flag (TF) is set without an external
debugger attached, it can lead to an infinite loop in the SIGTRAP
handler. To avoid this, the software event flag in the augmented SS
must be cleared, ensuring that no single-step trap remains pending when
ERETU completes.
This test checks for that specific scenario—verifying whether the kernel
correctly prevents an infinite SIGTRAP loop in this edge case when FRED
is enabled.
The test should _always_ pass with IDT event delivery, thus no need to
disable the test even when FRED is not enabled.

Currently, __split_vma() triggers hugetlb page table unsharing through
vm_ops->may_split(). This happens before the VMA lock and rmap locks are
taken - which is too early, it allows racing VMA-locked page faults in our
process and racing rmap walks from other processes to cause page tables to
be shared again before we actually perform the split.
Fix it by explicitly calling into the hugetlb unshare logic from
__split_vma() in the same place where THP splitting also happens. At that
point, both the VMA and the rmap(s) are write-locked.
An annoying detail is that we can now call into the helper
hugetlb_unshare_pmds() from two different locking contexts:
1. from hugetlb_split(), holding:
- mmap lock (exclusively)
- VMA lock
- file rmap lock (exclusively)
2. hugetlb_unshare_all_pmds(), which I think is designed to be able to
call us with only the mmap lock held (in shared mode), but currently
only runs while holding mmap lock (exclusively) and VMA lock
Backporting note:
This commit fixes a racy protection that was introduced in commit
b30c14cd6102 ("hugetlb: unshare some PMDs when splitting VMAs"); that
commit claimed to fix an issue introduced in 5.13, but it should actually
also go all the way back.

arch_timer_edge_cases
arch_timer_edge_cases uses ~0 as the maximum counter value, however there's
no architectural guarantee that this is valid.
Figure out the effective counter width based on the effective frequency
like it's done by the kernel.
This also serves as a workaround for AC03_CPU_14 that led to the
following assertion failure on ampere-one machines:
==== Test Assertion Failure ====
arm64/arch_timer_edge_cases.c:169: timer_condition == istatus
pid=11236 tid=11236 errno=4 - Interrupted system call
1 0x0000000000404ce7: test_run at arch_timer_edge_cases.c:938
2 0x0000000000401ebb: main at arch_timer_edge_cases.c:1053
3 0x0000ffff9fa8625b: ?? ??:0
4 0x0000ffff9fa8633b: ?? ??:0
5 0x0000000000401fef: _start at ??:?
0x1 != 0x0 (timer_condition != istatus)
Note that the following subtest only worked since the counter initialized
with CVAL_MAX would instantly overflow (which is no longer the case):
test_set_cnt_after_cval_no_irq(timer, 0, DEF_CNT, CVAL_MAX, sm);
To fix this we could swap CVAL_MAX for 0 here but since that is already
done by test_move_counters_behind_timers() let's remove that subtest.
