[PATCH v4 00/20] target/arm: Implement PAN, ATS1E1, UAO

Posted by Richard Henderson 5 years, 9 months ago

Based-on: https://git.linaro.org/people/peter.maydell/qemu-arm.git/log/?h=target-arm.next

Version 4 incorporates the feedback on v3.  In particular:
  * Split out CPSR_J masking to its own patch.
  * Merge trivial braces formatting fixes into patch 5.
  * Drop "Tidy msr_mask" patch, leaving CPSR_USER handling alone.
  * Fixes for EL3 in "Set PAN bit as required on exception entry".

Patches without review:

  0005-target-arm-Split-out-aarch32_cpsr_valid_mask.patch
  0006-target-arm-Mask-CPSR_J-when-Jazelle-is-not-enable.patch
  0009-target-arm-Remove-CPSR_RESERVED.patch
  0014-target-arm-Set-PAN-bit-as-required-on-exception-e.patch
