Because of the above, I dropped Gustavo's t-b.

Since this patchset fixes the "prctl() failed: Invalid argument"
on QEMU user-mode when both flags (ASYNC | SYNC) are passed
to prctl(PR_SET_TAGGED_ADDR_CTRL, ...), I tested it again --
expecting no different result -- so:

Tested-by: Gustavo Romero 

If that t-b tag doesn't make sense, feel free to drop it :)

Thanks for fixing it!

[PATCH v3 0/6] target/arm: assorted mte fixes

[Richard Henderson]

Changes for v3:
  - As if /sys/devices/system/cpu/cpu/mte_tcf_preferred is "sync".
  - Fix do_st_zpa as well as do_ld_zpa.  Oops.

Because of the above, I dropped Gustavo's t-b.
