[VIRT-294 # ARMv8.3-PAuth, Pointer Authentication ]

Posted v3 based on feedback.

[VIRT-339 # ARMv8.5-BTI, Branch Target Identification ]

Posted "v1" to qemu-devel, rebased on v3 pauth

[VIRT-344 # ARMv8.5-MemTag, Memory Tagging Extension ]

Progressed to the "write a standalone test case" stage for linux-user. I'll need to discuss address space stuff w/ PMM for system mode. Discovered while writing a test case for this that my document and gas do not agree on the instruction encodings. Putting this on hold until query about document revision numbers is answered.

Posted pieces of this implementing TBI for aarch64-linux-user.

[VIRT-327 # Richard's upstream QEMU work ]

Fixed alpha-linux-user fpcr initialization. Fixed alpha-softmmu double-increment of SIGILL address.

Sent v2 patchset for target/arm use of gvec minmax routines.
