[PATCH 0/2] Change default pointer authentication algorithm on aarch64 to impdef

[Pierrick Bouvier]

qemu-system-aarch64 default pointer authentication (QARMA5) is expensive, we
spent up to 50% of the emulation time running it (when using TCG).

Switching to pauth-impdef=on is often given as a solution to speed up execution.
Thus we talked about making it the new default.

The first patch introduce a new property (pauth-qarma5) to allow to select
current default algorithm.
The second one change the default.

Pierrick Bouvier (2):
  target/arm: add new property to select pauth-qarma5
  target/arm: change default pauth algorithm to impdef
