I was looking at trying to bring this into target-arm.next,
since the changes in patches 1 and 2 for code review
comments are not large. However I found that it fails
"make check":

ERROR:../../tests/qtest/arm-cpu-features.c:425:pauth_tests_default:
assertion failed: (g_str_equal(_error, "cannot enable pauth-impdef
without pauth"))

as a result of patch 8's changes to the handling
of the CPU pauth related properties.

The assertion seems to be because patch 8 has changed
the error string to something different from that which
the test case is looking for.

Patch 8 needs to also update the test case to include
testing of the handling of the new properties it adds.

thanks
