Message

v3 of:

diff to v2:
- In 1/4 I've reworked setting errno because of how posix_madvise()
  behaves on Darwin,
- In 4/4 I'm now using size_to_str() to print the page size, oh, and the
  error message now contains the backend name too.

Michal Privoznik (4):
  osdep: Make qemu_madvise() to set errno in all cases
  osdep: Make qemu_madvise() return ENOSYS on unsupported OSes
  backends/hostmem: Report error on qemu_madvise() failures
  backends/hostmem: Report error when memory size is unaligned
