The first patch fixes the problem that hugepages cannot be used via
the "memory-backend-memfd" object on s390x. The second and third patch
are some clean-ups that can be done after generalizing the code in the
first patch.

  - Use qemu_ram_pagesize(memdev->mr.ram_block) instead of adding
    additional code for the memfd object
  - Added the two clean-up patches on top to simplify the code

Thomas Huth (3):
   backends/hostmem: Fix support of memory-backend-memfd in
   softmmu/physmem: Remove the ifdef __linux__  around the pagesize
   util/mmap-alloc: Remove qemu_mempath_getpagesize()

Thanks to David and Claudio for the reviews! FWIW, I'll take this through my s390x-next branch since it fixes a s390x-related problem:
