[PATCH] small apic timer cleanup

[PATCH] small apic timer cleanup

[Brian Gerst]

[-- Attachment #1: Type: text/plain, Size: 193 bytes --]

This small patch removes the special case macro for the apic timer entry
stub, as it unnecessary to pass in the pointer to the pt_regs struct. 
Tested on a UP Athlon XP.
