[PATCHv4 0/3] x86/mm/encrypt: Cleanup and switching between paging modes<Paste>

[Kirill A. Shutemov]

This patcheset is a preparation set for boot-time switching between
paging modes. Please review and consider applying.

Code around sme_populate_pgd() is unnecessary complex and hard to modify.

This patchset rewrites it in more stream-lined way to add support of
boot-time switching between paging modes.

I haven't tested the patchset on hardware capable of memory encryption.

v4:
 - Move sev_enabled declaration to <linux/mem_encrypt.h>
 - Fix few typos in commit messages
 - Reviewed/Tested-by from Tom
v3:
 - Move all page table related functions into mem_encrypt_identity.c
v2:
 - Rebased to up-to-date tip

Kirill A. Shutemov (3):
  x86/mm/encrypt: Move page table helpers into separate translation unit
  x86/mm/encrypt: Rewrite sme_populate_pgd() and
    sme_populate_pgd_large()
  x86/mm/encrypt: Rewrite sme_pgtable_calc()
