Add a matching sysctl to go with CONFIG_SYSCALL_USER_DISPATCH.
kernel.syscall_user_dispatch (default 1 - allow) controls whether
userspace may arm syscall user dispatch (both via prctl and ptrace).
Disarming is always permitted - same semantics as comparable knobs.
Disabling while a task has armed syscall user dispatch does not
cause it to become inactive - instead it remains active until the
user attempts to disable/re-enable via prctl or ptrace. On the
next attempt to re-enable, the prctl/ptrace call fails gracefully.
The alternative would cause programs translating non-linux syscalls
to interpret those syscalls as linux syscalls, resulting in undefined
userland behavior.

It's no longer used outside of mm/.
Since this means __alloc_pages_noprof() is no longer visible from gfp.h,
this also means moving the definition of alloc_pages_node_noprof into
the .c file.
Also remove references to this API from the documentation tree -
referring to the specific function name was already questionable but
now the function is not even public it definitely seems wrong.

Currently, hugetlb_cma reservation only supports absolute sizes (e.g.,
hugetlb_cma=2G or hugetlb_cma=0:1G,1:1G). This can be restrictive in
heterogeneous environments or when deploying common kernel command lines
across machines with different memory capacities.
Add support for percentage-based hugetlb_cma reservation (e.g.,
hugetlb_cma=20% or hugetlb_cma=0:20%,1:10%).
The percentage is calculated against the total memory (for global
settings) or against the node-specific memory (for node-specific
settings) using memblock APIs during early boot.

The io.stat section says that enabling the io.latency controller exposes
the depth, avg_lat and win stats in addition to the normal ones. However,
these io.latency-specific stats are debug stats and are only emitted when
the blkcg_debug_stats module parameter is enabled, which is disabled by
default.
Make this explicit so users do not expect these fields to appear in
io.stat by default, and qualify the usage text that suggests using
avg_lat to pick an io.latency target.

AF_ALG is a frequent source of vulnerabilities and a maintenance
nightmare. It exposes far more functionality to userspace than ever
should have been exposed, especially to unprivileged processes. Recent
exploits have targeted kernel internal implementation details like
"authencesn" that have zero use case for userspace access.
Fortunately, AF_ALG is rarely used in practice, as userspace crypto
libraries exist. And when it is used, only some functionality is known
to be used, and many users are known to hold capabilities already.
iwd for example requires CAP_NET_ADMIN and has a known algorithm list
(https://lore.kernel.org/linux-crypto/bcbbef00-5881-421b-8892-7be6c04b832d@gmail.com/).
Thus, let's restrict the set of allowed algorithms by default, depending
on the capabilities held.
Add a sysctl /proc/sys/crypto/af_alg_restrict with meaning:
0: unrestricted
1: limited functionality
2: completely disabled
Set the default value to 1, which enables an algorithm allowlist for
unprivileged processes and a slightly longer allowlist for privileged
processes.
Note that the list may be tweaked in the future. However, the common
use cases such as iwd and bluez are taken into account already. I've
tested that iwd still works with the default value of 1.

Add a section describing CONFIG_CMDLINE_FROM_BOOTCONFIG: what it
does (renders the embedded "kernel" subtree to a flat cmdline at
build time so early_param() handlers see the values), what it
requires (BOOT_CONFIG_EMBED, a non-empty BOOT_CONFIG_EMBED_FILE,
CONFIG_CMDLINE to be empty, and ARCH_SUPPORTS_CMDLINE_FROM_BOOTCONFIG --
currently x86 only), the bootconfig opt-in semantics, the initrd-vs-embedded
precedence, and the soft-error overflow behavior.
This addresses feedback from the Sashiko AI review and Masami Hiramatsu to
document the CONFIG_CMDLINE requirement, which is enforced at the Kconfig
level but was not mentioned in the documentation, potentially confusing users
who might satisfy all other requirements but still find the option hidden in
menuconfig if CONFIG_CMDLINE is non-empty.

The userland visible page flags (KPF_*) were initially moved to
include/linux/kernel-page-flags.h in commit 1a9b5b7fe0c5 ("mm: export

include/uapi/linux/kernel-page-flags.h in commit 607ca46e97a1 ("UAPI:
(Scripted) Disintegrate include/linux"). Update the doc to reflect the
current location of these flags.
The member @walk_end of struct pm_scan_arg {} was wrongly written as
"end_walk".
The first sample code of the PAGEMAP_SCAN ioctl wrongly used the
PM_SCAN_CHECK_WPASYNC flag twice, instead of the PM_SCAN_WP_MATCHING flag.
The second one included the wrong category in the required mask -
PAGE_IS_FILE should be used instead of PAGE_IS_SWAPPED as per the
intention.
Fix them all together.

Commit 35c18f2933c5 ("Add a new optional ",cma" suffix to the
crashkernel= command line option") and commit ab475510e042 ("kdump:
implement reserve_crashkernel_cma") added CMA support for kdump
crashkernel reservation. This allows the kernel to dynamically allocate
contiguous memory for crash dumping when needed, rather than permanently
reserving a fixed region at boot time.
So extend crashkernel CMA reservation support to riscv. The following
changes are made to enable CMA reservation:
- Parse and obtain the CMA reservation size along with other crashkernel
parameters.
- Call reserve_crashkernel_cma() to allocate the CMA region for kdump.
- Include the CMA-reserved ranges for kdump kernel to use, which was
already done in of_kexec_alloc_and_setup_fdt().
- Exclude the CMA-reserved ranges from the crash kernel memory to
prevent them from being exported through /proc/vmcore, which was
already done in the crash core.
Update kernel-parameters.txt to document CMA support for crashkernel on
riscv architecture.

Commit 35c18f2933c5 ("Add a new optional ",cma" suffix to the
crashkernel= command line option") and commit ab475510e042 ("kdump:
implement reserve_crashkernel_cma") added CMA support for kdump
crashkernel reservation.
Crash kernel memory reservation wastes production resources if too
large, risks kdump failure if too small, and faces allocation difficulties
on fragmented systems due to contiguous block constraints. The new
CMA-based crashkernel reservation scheme splits the "large fixed
reservation" into a "small fixed region + large CMA dynamic region": the
CMA memory is available to userspace during normal operation to avoid
waste, and is reclaimed for kdump upon crash—saving memory while
improving reliability.
So extend crashkernel CMA reservation support to arm64. The following
changes are made to enable CMA reservation:
- Parse and obtain the CMA reservation size along with other crashkernel
parameters.
- Call reserve_crashkernel_cma() to allocate the CMA region for kdump.
- Include the CMA-reserved ranges for kdump kernel to use.
- Exclude the CMA-reserved ranges from the crash kernel memory to

Add documentation for the cpu.stat.local interface file, which reports
the throttled_usec stat -- the actual throttling time incurred by the
cgroup's own runqueues, which may include throttling inherited from
ancestor cgroup bandwidth limits. Unlike cpu.stat's throttled_usec
which only accounts for throttling caused by the cgroup's own CFS
bandwidth limit.
When the controller is not enabled, the stat is not reported.
Also clarify cpu.stat descriptions: note that the three base CPU usage
stats (usage_usec, user_usec, system_usec) include descendant cgroups,
and that the five CFS bandwidth stats are non-hierarchical -- they only
account for throttling caused by the cgroup's own bandwidth limit.

The mempool subsystem historically wrapped its debugging logic inside an
merely defines compile-time defaults for SLUB and caused two flaws:
1. On production kernels where CONFIG_SLUB_DEBUG=y but
CONFIG_SLUB_DEBUG_ON=n, mempool debugging was completely compiled out
at compile time.
2. On kernels with CONFIG_SLUB_DEBUG_ON=y, mempool debugging stayed active
even if a user explicitly disabled slub debugging at boot time.
Clean up this mess by removing the #ifdef and switching to a runtime static
key (mempool_debug_enabled), allowing mempool debugging to be toggled
cleanly via its own boot parameter.

cpuset_update_tasks_nodemask()
As reported by sashiko [1], cpuset_update_tasks_nodemask() will do
mpol_rebind_mm() and possibly cpuset_migrate_mm() for all threads of
a multithreaded process. Since commit 3df9ca0a2b8b ("cpuset: migrate
memory only for threadgroup leaders"), cpuset_attach() had been updated
to rebind and migrate memory only for threadgroup leaders to mark the
group leader as the owner of the mm_struct.
To be consistent and avoid unnecessary performance overhead for heavily
multithreaded processes, follow the cpuset_attach() example and perform
memory rebind and migration only for threadgroup leaders.
Also add a paragraph in cgroup-v2.rst under cpuset.mems that the
threadgroup leader is the memory owner of that threadgroup. Therefore
the non-leading threads shouldn't be in other cgroups whose "cpuset.mems"
doesn't fully overlap that of the group leader.

hugepage could mean both THP and HugeTLB these days.
Rename hugepage-* tests for HugeTLB to hugetlb-* to avoid confusion.
Make sure that Makefile update keeps alphabetical ordering of the
TEST_GEN_FILES entries.
Keep old binary names in .gitignore because Linus prefers it this way.

Both tests create a hugettlb mapping, fill it with data and verify the
data, the only difference is that one uses file-backed memory and another
one uses anonymous memory.

Add three new mTHP statistics to track collapse failures for different
orders when encountering swap PTEs, excessive none PTEs, and shared PTEs:
- collapse_exceed_swap_pte: Increment when mTHP collapse fails due to
encountering a swap PTE.
- collapse_exceed_none_pte: Counts when mTHP collapse fails due to
exceeding the none PTE threshold for the given order
- collapse_exceed_shared_pte: Counts when mTHP collapse fails due to
encountering a shared PTE.
These statistics complement the existing THP_SCAN_EXCEED_* events by
providing per-order granularity for mTHP collapse attempts. The stats are
exposed via sysfs under
`/sys/kernel/mm/transparent_hugepage/hugepages-*/stats/` for each
supported hugepage size.
As we currently do not support collapsing mTHPs that contain a swap or
shared entry, those statistics keep track of how often we are encountering
failed mTHP collapses due to these restrictions.
We will add support for mTHP collapse for anonymous pages next; lets also
track when this happens at the PMD level within the per-mTHP stats.
