[PATCH 0/2] x86-64: allow using RIP-relative addressing for per-CPU data

[Jan Beulich]

Observing that per-CPU data (in the SMP case) is reachable by
exploiting 64-bit address wraparound, these two patches
arrange for using the one byte shorter RIP-relative addressing
forms for the majority of per-CPU accesses.

1: handle PC-relative relocations on per-CPU data
2: use RIP-relative addressing for most per-CPU accesses
