commit 3239cfafbf1c9f8418a7ff1b3567b2bfb983f30d
Author: Julien Cristau <[EMAIL PROTECTED]>
Date: Wed Jan 23 18:20:23 2008 +0100
Fix sigill on CPUs which don't support the cpuid instruction.
Add patch by Michael Karcher <[EMAIL PROTECTED]> to fix inline
asm in fb/fbpict.c. On processors without the cpuid instruction, the X
server would get a SIGILL (closes: #353494).
