==================================================================

While reviewing the patch, Honza found that when adjusting resize_bg in
alloc_flex_gd(), it was possible for flex_gd->resize_bg to be bigger than
flexbg_size.

The reproduction of the problem requires the following:

 o_group = flexbg_size * 2 * n;
 o_size = (o_group + 1) * group_size;
 n_group: [o_group + flexbg_size, o_group + flexbg_size * 2)
 o_size = (n_group + 1) * group_size;

Take n=0,flexbg_size=16 as an example:

              last:15
|o---------------|--------------n-|
o_group:0    resize to      n_group:30

The corresponding reproducer is:

img=test.img
rm -f $img
truncate -s 600M $img
mkfs.ext4 -F $img -b 1024 -G 16 8M
dev=`losetup -f --show $img`
mkdir -p /tmp/test
mount $dev /tmp/test
resize2fs $dev 248M

Delete the problematic plus 1 to fix the issue, and add a WARN_ON_ONCE()
to prevent the issue from happening again.

[ Note: another reproucer which this commit fixes is:

  img=test.img
  rm -f $img
  truncate -s 25MiB $img
  mkfs.ext4 -b 4096 -E nodiscard,lazy_itable_init=0,lazy_journal_init=0 $img
  truncate -s 3GiB $img
  dev=`losetup -f --show $img`
  mkdir -p /tmp/test
  mount $dev /tmp/test
  resize2fs $dev 3G
  umount $dev
  losetup -d $dev

Calling ext4_fc_mark_ineligible() with a NULL handle is racy and may result
in a fast-commit being done before the filesystem is effectively marked as
ineligible.  This patch moves the call to this function so that an handle
can be used.  If a transaction fails to start, then there's not point in
trying to mark the filesystem as ineligible, and an error will eventually be
returned to user-space.

Pull tracing fixes from Steven Rostedt:

 - Fix tp_printk command line option crashing the kernel

   With the code that can handle a buffer from a previous boot, the
   trace_check_vprintf() needed access to the delta of the address space
   used by the old buffer and the current buffer. To do so, the
   trace_array (tr) parameter was used. But when tp_printk is enabled on
   the kernel command line, no trace buffer is used and the trace event
   is sent directly to printk(). That meant the tr field of the iterator
   descriptor was NULL, and since tp_printk still uses
   trace_check_vprintf() it caused a NULL dereference.

 - Add ptrace.h include to x86 ftrace file for completeness

 - Fix rtla installation when done with out-of-tree build

 - Fix the help messages in rtla that were incorrect

 - Several fixes to fix races with the timerlat and hwlat code

   Several locking issues were discovered with the coordination between
   timerlat kthread creation and hotplug. As timerlat has callbacks from
   hotplug code to start kthreads when CPUs come online. There are also
   locking issues with grabbing the cpu_read_lock() and the locks within
   timerlat.

during the v6.12 merge window:

8b985bbf ("tomoyo: allow building as a loadable LSM module")
268225a1 ("tomoyo: preparation step for building as a loadable LSM module")

Together these two patches introduced the CONFIG_SECURITY_TOMOYO_LKM
Kconfig build option which enabled a TOMOYO specific dynamic LSM loading
mechanism (see the original commits for more details).  Unfortunately,
this approach was widely rejected by the LSM community as well as some
members of the general kernel community.  Objections included concerns
over setting a bad precedent regarding individual LSMs managing their
LSM callback registrations as well as general kernel symbol exporting
practices.  With little to no support for the CONFIG_SECURITY_TOMOYO_LKM
approach outside of Tetsuo, and multiple objections, we need to revert
these changes.

We received a regression report for System76 Pangolin (pang14) due to
the recent fix for Tuxedo Sirius devices to support the top speaker.
The reason was the conflicting PCI SSID, as often seen.

As a workaround, now the codec SSID is checked and the quirk is
applied conditionally only to Sirius devices.

Brandon reports sporadic, non-sensical spikes in cumulative pressure
time (total=) when reading cpu.pressure at a high rate. This is due to
a race condition between reader aggregation and tasks changing states.

While it affects all states and all resources captured by PSI, in
practice it most likely triggers with CPU pressure, since scheduling
events are so frequent compared to other resource events.

The race context is the live snooping of ongoing stalls during a
pressure read. The read aggregates per-cpu records for stalls that
have concluded, but will also incorporate ad-hoc the duration of any
active state that hasn't been recorded yet. This is important to get
timely measurements of ongoing stalls. Those ad-hoc samples are
calculated on-the-fly up to the current time on that CPU; since the
stall hasn't concluded, it's expected that this is the minimum amount
of stall time that will enter the per-cpu records once it does.

The problem is that the path that concludes the state uses a CPU clock
read that is not synchronized against aggregators; the clock is read
outside of the seqlock protection. This allows aggregators to race and
snoop a stall with a longer duration than will actually be recorded.

With the recorded stall time being less than the last snapshot
remembered by the aggregator, a subsequent sample will underflow and
observe a bogus delta value, resulting in an erratic jump in pressure.

Fix this by moving the clock read of the state change into the seqlock
protection. This ensures no aggregation can snoop live stalls past the
time that's recorded when the state concludes.

After tracing the scheduling event, it was discovered that the migration
of the "timerlat/1" thread was performed during thread creation. Further
analysis confirmed that it is because the CPU online processing for
osnoise is implemented through workers, which is asynchronous with the
offline processing. When the worker was scheduled to create a thread, the
CPU may has already been removed from the cpu_online_mask during the offline
process, resulting in the inability to select the right CPU:

T1                       | T2
[CPUHP_ONLINE]           | cpu_device_down()
osnoise_hotplug_workfn() |
                         |     cpus_write_lock()
                         |     takedown_cpu(1)
                         |     cpus_write_unlock()
[CPUHP_OFFLINE]          |
    cpus_read_lock()     |
    start_kthread(1)     |
    cpus_read_unlock()   |

To fix this, skip online processing if the CPU is already offline.
