[PATCHv4 00/18] ARMv8.4-A Secure EL2

[Rémi Denis-Courmont]

        Hi,

The following changes since commit af3f37319cb1e1ca0c42842ecdbd1bcfc64a4b6f:

  Merge remote-tracking branch 'remotes/bonzini-gitlab/tags/for-upstream' into 
staging (2020-12-15 21:24:31 +0000)

follow.

Changes since version 3:
- Drop unnecessary changes of arm_mmu_idx_is_stage1_of_2() prototype.
- Fix RegimeEL() for S-EL0 on 32-bit.
- Translate NS bit after stage 2, not before it
  - Should fix bizarre configurations of V(S)TCR.(N)S{A,W} bits.
- Don't hard-code the list of stage 1 of 2 regimes.
