hm, this looks like a compiler bug: GCC might assume above that the 'regs'
parameter is the callee's (while in reality they are the caller's and we
rely on GCC not clobbering them on the stack).
Justin, does it work if you apply the patch below instead of the revert?
Thanks,
Ingo

Subject: [PATCH] x86: prevent tail call optimization in signal.c
Impact: fix firefox crash
Another victim of GCC believing that on-stack function arguments are
owned by the callee - while in reality for asmlinkage functions they
are very much owned by the caller. Stomping on them can corrupt the
user-space register state, causing weird crashes.

hm, that patch wont build because the protect_asmlinkage macro is rather
limited - it cannot deal with structure parameters.
We might be better off with a revert here, and a comment added that points
out the problem.

Below is the revert+document commit that i have queued up.
Justin, could you try the tip/master tree (which has this fix included):
http://people.redhat.com/mingo/tip.git/README
does Firefox still work fine?

Subject: [PATCH] Revert "x86: signal: change type of paramter for sys_rt_sigreturn()"
This reverts commit 4217458dafaa57d8e26a46f5d05ab8c53cf64191.
Justin Madru bisected this commit, it was causing weird Firefox
crashes.
The reason is that GCC mis-optimizes (re-uses) the on-stack parameters of
the calling frame, which corrupts the syscall return pt_regs state and
thus corrupts user-space register state.
So we go back to the slightly less clean but more optimization-safe
method of getting to pt_regs. Also add a comment to explain this.

I migrated now to the next ubuntu versio, hope it do no hava mach
difference.
There is no warnings in dmesg about mtrr or pat, no xorg crashes with
glxx but same pure performace. With enabled or disabled drm i get ~300fps
Alexey
To address the various issues raised on the stripping patches, this
patch
- adds a config option to control whether __crc_* symbols should be
stripped from modules (and restores filtering out __crc_* in
mksysmap)
- adds a fallback if the advanced module stripping fails during module
installation
- disallows KALLSYMS_STRIP_GENERATED for 32-bit Sparc
Parts based on a draft patch from Sam Ravnborg.

Yep. No crashing anymore. The commits starting from 31ad908 (work_on_cpu...)
seem to do the fixing.

Yeah I think it should, though it seems to be a rate controller bug and
not specific to ath5k.
