[CRIU] [PATCHv4 0/8] Large pages support for aarch64/ppc64

[Dmitry Safonov]

v4 Changes:
o aio tests failed case overflow in NR_IOEVENTS_IN_PAGES macro.

v3 Changes:
o PAGE_SIZE as a global in PIEs doesn't work on aarch64,
  I'll need to add relocs support to compel there eventually.
  Revert this simplification to v1.

v2 Changes:
o Add patches for global variables in PIEs
o Simplify ARCH_HAS_LONG_PAGES
o cache PAGE_SIZE and PAGE_SHIFT values
  (as nitpicked by Mike)

TLDR; CRIU doesn't work if:
on aarch64 it's when PAGE_SIZE!=4K,
on ppc64 it's when PAGE_SIZE!=64K
