Pull arm64 fixes from Will Deacon:
"Late arm64 fixes.
They fix very early boot failures with KASLR where the early mapping
of the kernel is incorrect, so the failure mode looks like a hang with
no output. There's also a signal-handling fix when a uaccess routine
faults with a fatal signal pending, which could be used to create
unkillable user tasks using userfaultfd and finally a state leak fix
for the floating pointer registers across a call to exec().
We're still seeing some random issues crop up (inode memory corruption
and spinlock recursion) but we've not managed to reproduce things
reliably enough to debug or bisect them yet.
Summary:
- Fix very early boot failures with KASLR enabled
- Fix fatal signal handling on userspace access from kernel
- Fix leakage of floating point register state across exec()"
