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.
