Patch series "nilfs2: eliminate kmap and kmap_atomic calls".

This series converts remaining kmap and kmap_atomic calls to use
kmap_local, mainly in metadata files, and eliminates calls to these
deprecated kmap functions from nilfs2.

This series does not include converting metadata files to use folios, but
it is a step in that direction.

Most conversions are straightforward, but some are not: the checkpoint
file, the inode file, and the persistent object allocator.  These have
been adjusted or rewritten to avoid multiple kmap_local calls or nest them
if necessary, and to eliminate long waits like block I/O within the
highmem mapping sections.

This series has been tested in both 32-bit and 64-bit environments with
varying block sizes.


This patch (of 15):

In the recovery function when mounting, nilfs_recovery_copy_block() uses
the deprecated kmap_atomic(), so convert it to use kmap_local.

Instead of popping only the maximum element from the heap during each
iteration, we now pop the two largest elements at once.  Although this
introduces an additional comparison to determine the second largest
element, it enables a reduction in the height of the tree by one during
the heapify operations starting from root's left/right child.  This
reduction in tree height by one leads to a decrease of one comparison and
one swap.

This optimization results in saving approximately 0.5 * n swaps without
increasing the number of comparisons.  Additionally, the heap size during
heapify is now one less than the original size, offering a chance for
further reduction in comparisons and swaps.

The following experimental data is based on the array generated using
get_random_u32().

| N     | swaps (old) | swaps (new) | comparisons (old) | comparisons (new) |

Patch series "lib/sort: Optimize the number of swaps and comparisons".

This patch series aims to optimize the heapsort algorithm, specifically
targeting a reduction in the number of swaps and comparisons required.


This patch (of 2):

Currently, when searching for the sift-down path and encountering equal
elements, the algorithm chooses the left child.  However, considering that
the height of the right subtree may be one less than that of the left
subtree, selecting the right child in such cases can potentially reduce
the number of comparisons and swaps.

For instance, when sorting an array of 10,000 identical elements, the
current implementation requires 247,209 comparisons.  With this patch, the
number of comparisons can be reduced to 227,241.

After 25b21cb2 ("[PATCH] IPC namespace core") and 4e982311
("[PATCH] IPC namespace - shm") the shared memory page count stopped being
global and started counting per ipc namespace.  The documentation and
shmget(2) still says that shmall is a global option.

shmget(2):

SHMALL System-wide limit on the total amount of shared memory, measured in
units of the system page size.  On Linux, this limit can be read and
modified via /proc/sys/kernel/shmall.

I think the changes made in 2006 should be documented.

Patch series "Allow to change ipc/mq sysctls inside ipc namespace", v3.

Right now ipc and mq limits count as per ipc namespace, but only real root
can change them.  By default, the current values of these limits are such
that it can only be reduced.  Since only root can change the values, it is
impossible to reduce these limits in the rootless container.

We can allow limit changes within ipc namespace because mq parameters are
limited by RLIMIT_MSGQUEUE and ipc parameters are not limited to anything
other than cgroups.


This patch (of 3):

Rootless containers are not allowed to modify kernel IPC parameters.

All default limits are set to such high values that in fact there are no
limits at all.  All limits are not inherited and are initialized to
default values when a new ipc_namespace is created.

For new ipc_namespace:

size_t       ipc_ns.shm_ctlmax = SHMMAX; // (ULONG_MAX - (1UL << 24))
size_t       ipc_ns.shm_ctlall = SHMALL; // (ULONG_MAX - (1UL << 24))
int          ipc_ns.shm_ctlmni = IPCMNI; // (1 << 15)
int          ipc_ns.shm_rmid_forced = 0;
unsigned int ipc_ns.msg_ctlmax = MSGMAX; // 8192
unsigned int ipc_ns.msg_ctlmni = MSGMNI; // 32000
unsigned int ipc_ns.msg_ctlmnb = MSGMNB; // 16384

The shm_tot (total amount of shared pages) has also ceased to be global,
it is located in ipc_namespace and is not inherited from anywhere.

In such conditions, it cannot be said that these limits limit anything. 
The real limiter for them is cgroups.

If we allow rootless containers to change these parameters, then it can
only be reduced.

Optimize the min_heapify() function, resulting in a significant reduction
of approximately 50% in the number of comparisons for large random inputs,
while maintaining identical results.

The current implementation performs two comparisons per level to identify
the minimum among three elements.  In contrast, the proposed bottom-up
variation uses only one comparison per level to assess two children until
reaching the leaves.  Then, it sifts up until the correct position is
determined.

Typically, the process of sifting down proceeds to the leaf level,
resulting in O(1) secondary comparisons instead of log2(n).  This
optimization significantly reduces the number of costly indirect function
calls and improves overall performance.

LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues.  While all of the links are still valid, they may not necessarily
show the most up to date information around the issues, as all updates
will occur on GitHub, not Bugzilla.

Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number.  Thankfully, LLVM maintains this mapping
through two shortlinks:

  https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
  https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>

Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up to
date information.  Each migrated issue links back to the Bugzilla entry,
so there should be no loss of fidelity of information here.

ilog2() rounds down, so for example when PowerPC 85xx sets CONFIG_NR_CPUS
to 24, we will only allocate 4 bits to store the number of CPUs instead of
5.  Use bits_per() instead, which rounds up.  Found by code inspection. 
The effect of this would probably be a misaccounting when doing NUMA
balancing, so to a user, it would only be a performance penalty.  The
effects may be more wide-spread; it's hard to tell.

 "This is a bit of a big batch for rc4, but just due to holiday hangover
  and because I didn't send any fixes last week due to a late revert

     '-fpatchable-function-entry'

   - Fix accuracy of stolen time on pseries since the switch to
     VIRT_CPU_ACCOUNTING_GEN

   - Fix a crash in the IOMMU code when doing DLPAR remove

   - Set pt_regs->link on scv entry to fix BPF stack unwinding

   - Add missing PPC_FEATURE_BOOKE on 64-bit e5500/e6500, which broke
     gdb

   - Fix boot on some 6xx platforms with STRICT_KERNEL_RWX enabled

   - Fix build failures with KASAN enabled and 32KB stack size

Pull driver core fixes from Greg KH:
 "Here are some driver core fixes, a kobject fix, and a documentation
  update for 6.8-rc5. In detail these changes are:

   - devlink fixes for reported issues with 6.8-rc1

   - topology scheduling regression fix that has been reported by many

   - kobject loosening of checks change in -rc1 is now reverted as some
     codepaths seemed to need the checks

   - documentation update for the CVE process. Has been reviewed by
     many, the last minute change to the document was to bring the .rst
     format back into the the new style rules, the contents did not
     change.

  All of these, except for the documentation update, have been in
  linux-next for over a week. The documentation update has been reviewed
  for weeks by a group of developers, and in public for a week and the
  wording has stabilized for now. If future changes are needed, we can
