Description of problem:
./include/linux/delay.h of the kernel source causes FC2 under i386/amd athlon/others? to crash (in the compiled/running kernel) after changing the .config HZ value (make menuconfig) to a power of 2 (e.g. 4096).

changing line 31 (in mdelay)
from:   unsigned long __ms=(n);
to:     unsigned long __ms=((n*5)>>2);

should fix the problem.


Note: this problem came up during kernel development and requires several other source code changes to reproduce.  






Version-Release number of selected component (if applicable):
kernel-2.6.10-1.771_FC2

How reproducible:
Always

Steps to Reproduce:
1. see Note in description
2. try higher power of 2 .config HZ values
3. easier to discover with GL apps (e.g. NVIDIA/quake arena)
