sched-urgent-2020-11-15

A set of scheduler fixes:

 - Address a load balancer regression by making the load balancer use the
   same logic as the wakeup path to spread tasks in the LLC domain.

 - Prefer the CPU on which a task run last over the local CPU in the fast
   wakeup path for asymmetric CPU capacity systems to align with the
   symmetric case. This ensures more locality and prevents massive
   migration overhead on those asymetric systems

 - Fix a memory corruption bug in the scheduler debug code caused by
   handing a modified buffer pointer to kfree().

perf-urgent-2020-11-15

A set of fixes for perf:

 - A set of commits which reduce the stack usage of various perf event
   handling functions which allocated large data structs on stack causing
   stack overflows in the worst case.

 - Use the proper mechanism for detecting soft interrupts in the recursion
   protection.

 - Make the resursion protection simpler and more robust.

 - Simplify the scheduling of event groups to make the code more robust and
   prepare for fixing the issues vs. scheduling of exclusive event groups.

 - Prevent event multiplexing and rotation for exclusive event groups

 - Correct the perf event attribute exclusive semantics to take pinned
   events, e.g. the PMU watchdog, into account

 - Make the anythread filtering conditional for Intel's generic PMU
   counters as it is not longer guaranteed to be supported on newer
   CPUs. Check the corresponding CPUID leaf to make sure.

 - Fixup a duplicate initialization in an array which was probably cause by
   the usual copy & paste - forgot to edit mishap.

locking-urgent-2020-11-15

Two fixes for the locking subsystem:

  - Prevent an unconditional interrupt enable in a futex helper function
    which can be called from contexts which expect interrupts to stay
    disabled across the call.

  - Don't modify lockdep chain keys in the validation process as that
    causes chain inconsistency.

efi-urgent-for-v5.10-rc3

Couple of EFI fixes for v5.10:
- fix memory leak in efivarfs driver
- fix HYP mode issue in 32-bit ARM version of the EFI stub when built in
  Thumb2 mode
- avoid leaking EFI pgd pages on allocation failure

vfs-5.10-fixes-2

More VFS fixes for 5.10-rc4:
- Minor cleanups of the sb_start_* fs freeze helpers.

vfs-5.10-fixes-1

VFS fixes for 5.10-rc4:
- Finally remove the "convert to trylock" weirdness in the fs freezer
  code.  It was necessary 10 years ago to deal with nested transactions
  in XFS, but we've long since removed that; and now this is causing
  subtle race conditions when lockdep goes offline and sb_start_* aren't
  prepared to retry a trylock failure.

xfs-5.10-fixes-5

Fixes for 5.10-rc4:
- Fix a fairly serious problem where the reverse mapping btree key
comparison functions were silently ignoring parts of the keyspace when
doing comparisons.
- Fix a thinko in the online refcount scrubber.
- Fix a missing unlock in the pnfs code.

My kernel's main integration branch is 'orange-pi-$VER' (this one).
No other branch is supposed to work alone. My defconfigs are tested
and work on the boards I support. Read the README.md for more info.

Only my branches based on the current mainline kernel branch are
maintained (those are usually the -rc# kernels!). You can find the
current mainline version here https://www.kernel.org/ (mainline: ...)

My prebuilt kernels can be found at https://xff.cz/kernels/ You can
use them to test that your board works, or just run them without
bothering with building everything yourself. I run them on all my
boards.

My website is https://xnux.eu and may contain useful advice.

Good luck!
