I've restructured tip/x86/xsave to be like this, and it can now be merged into tip/master without conficts.
I briefly merged it into tip/master to test it, but after about 10 randconfig iterations it ran into a spontaneous reboot crash. There's nothing in the log, the box (an Athlon64 X2) just reboots spontaneously. Removing the x86/xsave changes makes the system boot up fine.
I've pushed out the tree i tested into the tip/tmp.x86/xsave.broken branch. The bad config is:
http://redhat.com/~mingo/misc/config-Wed_Jul_30_20_09_12_CEST_2008.bad
Two crashlogs are here:
http://redhat.com/~mingo/misc/crash-Wed_Jul_30_20_09_12_CEST_2008.log
the serial log just stops at a certain point. It's not at a specific point, but the crash happened both times i tried to boot it.
