Adding support for the generic irq entry/exit handling for PowerPC. The
goal is to bring PowerPC in line with other architectures that already
use the common irq entry infrastructure, reducing duplicated code and
making it easier to share future changes in entry/exit paths.

Hello,

applying these patches on top of Linux 6.12 causes seccomp to return
different error (ENNOSYS instead of EPERM) causing some seccomp tests to
fail.

A minimal reporoducer is

podman run --rm --security-opt seccomp=<(echo '{"defaultAction":"SCMP_ACT_ALLOW","syscalls":[{"names":["mkdir"],"action":"SCMP_ACT_ERRNO"}]}') docker.io/library/alpine mkdir /tmp/test

This should produce 'Operation not permitted' but produces
'Function not implemented'.

Can you have a look?

Thanks

Michal
