Use 64-bit accesses for 64-bit floating-point general registers with PTRACE_PEEKUSR, removing the truncation of their upper halves in the FR=1 mode, caused by commit bbd426f542cb ("MIPS: Simplify FP context access"), which inadvertently switched them to using 32-bit accesses.
The PTRACE_POKEUSR side is fine as it's never been broken and continues using 64-bit accesses.

Hi,
Here's another one, spotted in the course of GDB PR gdb/22286 regression testing with the n64 ABI. Please apply.

Thanks, applied to mips-fixes, hopefully for 4.17 (but if it misses tomorrows linux-next it may have to wait 'til 4.18).
Cheers James
