[kvm-unit-tests PATCH v8 00/12] Cleanup low-level arch code

[Alexander Gordeev <agordeev@redhat.com>]

Hi all,

This is 8th attempt to make mainly x86 arch code consistent
with other architectures. This series is a prerequisite for
a follow-up "PCI bus support" series which I am going to
send separately.


Changes since v7:
  - PT_NX_MASK macro renamed to PT64_NX_MASK;
  - added patch "io: Unify IO accessors across architectures";

Changes since v6:
  - ioremap() PCD comment updated;
  - PT_PSE_MASK renamed to PT_PAGE_SIZE_MASK;
  - GENMASK_ULL used for PT_ADDR_MASK definition;
  - missed x86/taskswitch2.c update added;

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;
