[Qemu-devel] [PATCH v7 0/6] target/arm: Implement ARMv8.5-BTI for linux-user

[Richard Henderson]

Changes since v6:
  * Rebased on the ARMv8.1-VHE patch set.
  * Review from Dave Martin:
    + Remove PSTATE.BTYPE adjustment on syscall entry.
    + Rely on PT_GNU_PROPERTY to find the NT_GNU_PROPERTY_TYPE_0 note.
    + For the test case, add a linker script to create the PHDR.

Changes since v5:
  * New function to validate the target PROT parameter for mmap/mprotect.
  * Require BTI in the cpu for PROT_BTI set.
  * Set PSTATE.BTYPE=2 for the signal handler.
    Adjust the smoke test to match.
  * Tidy up the note parsing.
