A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the
recent rewrite of interrupt exit in C.
Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit.
These are all fairly minor with the exception of the change to evaluate the
get/put_user() arguments before we enable user access, which reduces the amount
of code we run with user access enabled.
A fix for our secure boot IMA rules, if enforcement of module signatures is
enabled at runtime rather than build time.
A fix to our 32-bit VDSO clock_getres() which wasn't falling back to the syscall
for unknown clocks.
A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another for 40x.
