[kvm-unit-tests PATCH v6 00/11] Cleanup low-level arch code

[Alexander Gordeev <agordeev@redhat.com>]

Hi Andrew et al,

This is 6th attempt to make mainly x86 arch code consistent
with other architectures.

Changes since v5:
  - ioremap() PCD comment added, the Reviewed-by preserved;
  - page table flag names changed from PTE_* to PT_*_MASK;

Changes since v4:
  - single instead of multiple pages allocation bug fixed in x86 ioremap();
  - style fixes squashed into code movements for lib/x86/asm/page.h and
    lib/x86/asm/barrier.h;
  - #ifndef __ASSEMBLY__ added to lib/x86/asm/page.h;

Changes since v3:
  - x86 PAGE_* constants and PTE_* flags cleaned up;
  - missing Reviewed-bys restored;
  - missing headers to lib/x86/asm/page.h and lib/x86/asm/barriers.h added
    (I did not remove already given Reviewed-bys from these);

Changes since v2:
  - x86 ioremap() address arithmetics nonsense fixed;
  - x86 virt_to_phys() and phys_to_virt() implementations left intact;
  - separate overrides of virt_to_phys() and phys_to_virt() added;
  - unsigned long size specifier removed from PAGE_SIZE constant;

Changes since v1:
  - arm compilation error fixed;
  - disabling memory re-ordering for generic memory barriers added;
