Subject: Updated RD/WRFS/GSBASE patchkit

This patchkit implements support for the RD(FS|GS)BASE instructions
in recent Intel CPUs. This allows both user programs to use 
these instructions to get additional address registers and do
user fast context switches, and optimizes some kernel paths (context
switch, paranoid interrupts) with them.

Main change in this version is porting to the recent entry_64.S changes
