Subject: Updated RD/WRFS/GSBASE patchkit
Date: Fri, 10 Apr 2015 08:50:25 -0700 [thread overview]
Message-ID: <1428681033-1549-1-git-send-email-andi@firstfloor.org> (raw)
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
