[PATCH v10 0/8] linux-user: User support for AArch64 BTI

[Richard Henderson]

The kernel abi for this was merged in v5.8, just as the qemu 5.1
merge window was closing, so this slipped to the next dev cycle.

Changes from v9:
  * Split what is now patch 7 into 3 more (pmm).
  * All prerequisites are now upstream.
