Merge tag 's390-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Heiko Carstens:

 - Add support for the hugetlb_cma command line option to allocate
   gigantic hugepages using CMA

 - Add arch_get_random_long() support.

 - Add ap bus userspace notifications.

 - Increase default size of vmalloc area to 512GB and otherwise let it
   increase dynamically by the size of physical memory. This should fix
   all occurrences where the vmalloc area was not large enough.

 - Completely get rid of set_fs() (aka select SET_FS) and rework address
   space handling while doing that; making address space handling much
   more simple.

 - Reimplement getcpu vdso syscall in C.

 - Add support for extended SCLP responses (> 4k). This allows e.g. to
   handle also potential large system configurations.

 - Simplify KASAN by removing 3-level page table support and only
   supporting 4-levels from now on.

 - Improve debug-ability of the kernel decompressor code, which now
   prints also stack traces and symbols in case of problems to the
   console.

 - Remove more power management leftovers.

 - Other various fixes and improvements all over the place.
