Subject: [PATCH] pps: Compatibility hack should be X86-specific
As of [1], using PPS_FETCH on a 64-bit ARM kernel with a 32-bit userland
is broken, returning a timeout. This is because the requested 4-byte
alignment for struct pps_ktime_compat (illegal on arm64) results in the
timeout flags field being uninitialised.
Make the hack specific to X86_64 builds with CONFIG_COMPAT defined.
[1] commit c2a49fe8eeef ("pps: fix padding issue with PPS_FETCH for
ioctl_compat")
See: https://github.com/raspberrypi/linux/issues/5430
Fixes: c2a49fe8eeef ("pps: fix padding issue with PPS_FETCH for ioctl_compat")
