Hello Linus,

please pull s390 changes for 5.12. There are small common code and
alpha/Kconfig changes caused by
96c0a6a72d18 ("s390,alpha: switch to 64-bit ino_t"). Which has been
discussed here: lkml.kernel.org/r/YCV7QiyoweJwvN+m@osiris

The following changes since commit 19c329f6808995b142b3966301f217c831e7cf31:

  Linux 5.11-rc4 (2021-01-17 16:37:05 -0800)

are available in the Git repository at:

for you to fetch changes up to 2223318c2862edc7f5b282939b850b19fc934ec4:

  s390/qdio: remove 'merge_pending' mechanism (2021-02-13 17:17:55 +0100)

Thank you,
Vasily
----------------------------------------------------------------
s390 updates for the 5.12 merge window

- Convert to using the generic entry infrastructure.

- Add vdso time namespace support.

- Switch s390 and alpha to 64-bit ino_t. As discussed here
  lkml.kernel.org/r/YCV7QiyoweJwvN+m@osiris

- Get rid of expensive stck (store clock) usages where possible. Utilize
  cpu alternatives to patch stckf when supported.

- Make tod_clock usage less error prone by converting it to a union and
  rework code which is using it.

- Machine check handler fixes and cleanups.

- Drop couple of minor inline asm optimizations to fix clang build.

- Default configs changes notably to make libvirt happy.

- Various changes to rework and improve qdio code.

- Other small various fixes and improvements all over the code.
