      Merge tag 's390-6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux · 0bdf4a8b
      Linus Torvalds authored 
      Pull more s390 updates from Heiko Carstens:

 - Add empty command line parameter handling stubs to kernel for all
   command line parameters which are handled in the decompressor. This
   avoids invalid "Unknown kernel command line parameters" messages from
   the kernel, and also avoids that these will be incorrectly passed to
   user space. This caused already confusion, therefore add the empty
   stubs

 - Add missing phys_to_virt() handling to machine check handler

 - Introduce and use a union to be used for zcrypt inline assemblies.
   This makes sure that only a register wide member of the union is
   passed as input and output parameter to inline assemblies, while
   usual C code uses other members of the union to access bit fields of
   it

 - Add and use a READ_ONCE_ALIGNED_128() macro, which can be used to
   atomically read a 128-bit value from memory. This replaces the
   (mis-)use of the 128-bit cmpxchg operation to do the same in cpum_sf
   code. Currently gcc does not generate the used lpq instruction if
   __READ_ONCE() is used for aligned 128-bit accesses, therefore use
   this s390 specific helper

 - Simplify machine check handler code if a task needs to be killed
   because of e.g. register corruption due to a machine malfunction

 - Perform CPU reset to clear pending interrupts and TLB entries on an
   already stopped target CPU before delegating work to it

 - Generate arch/s390/boot/vmlinux.map link map for the decompressor,
   when CONFIG_VMLINUX_MAP is enabled for debugging purposes

 - Fix segment type handling for dcssblk devices. It incorrectly always
   returned type "READ/WRITE" even for read-only segements, which can
   result in a kernel panic if somebody tries to write to a read-only
   device

 - Sort config S390 select list again

 - Fix two kprobe reenter bugs revealed by a recently added kprobe kunit
   test

* tag 's390-6.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:

  s390/rwonce: add READ_ONCE_ALIGNED_128() macro
  s390/ap,zcrypt,vfio: introduce and use ap_queue_status_reg union

      Commit 104ff59a ("ata: ahci: Add Tiger Lake UP{3,4} AHCI
controller") enabled low power mode for the Tiger Lake AHIC adapter in
the author system but created regressions for others. Revert this patch
for now until a better solution is found to make this adapter
eco-friendly.

      blk-mq: enforce op-specific segment limits in blk_insert_cloned_request · 49d24398
      Uday Shankar authored 
      The block layer might merge together discard requests up until the
max_discard_segments limit is hit, but blk_insert_cloned_request checks
the segment count against max_segments regardless of the req op. This
can result in errors like the following when discards are issued through
a DM device and max_discard_segments exceeds max_segments for the queue
of the chosen underlying device.

blk_insert_cloned_request: over max segments limit. (256 > 129)

Fix this by looking at the req_op and enforcing the appropriate segment
limit - max_discard_segments for REQ_OP_DISCARDs and max_segments for
everything else.
