Merge tag 's390-5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Vasily Gorbik:
- Convert to using the generic entry infrastructure.
- Add vdso time namespace support.
- Switch s390 and alpha to 64-bit ino_t. As discussed at
https://lore.kernel.org/linux-mm/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.
