Here is a patch against Linux 2.6.7 which fixes the sigmatch() macro to
work for the relatively old processors as well, which have 'pf == 0'
(processor flags as read from MSR 0x17), For example, the processors
failing without this patch are Pentium II 300 MHz (Klamath) with
family/model/stepping 6/3/4 and 6/3/3.

The patch also contains minor cosmetic changes (to make source code more
uniform).
