[PATCH v2 0/8] Relax sanity checking for mismatched AArch32 EL1

[Will Deacon]

Hi folks,

This is version two of the patches I previously posted here:

	https://lore.kernel.org/lkml/20200414213114.2378-1-will@xxxxxxxxxx/

Changes since v1 include:

  * Typo fixes
  * Added comment to update_32bit_cpu_features() callsite regarding sanitisation
  * Extended comment in final patch to mention KVM
  * Add acks/tested-bys

Cheers,

Will
