Duration of mdelay and udelay depends on MPU frequency in SMP

Hi All,

Can anyone please help me to understand and fix this issue?

When CPU frequency is "1008MHz", duration of delay was close to theoretical
value, however, when "300MHz", it was close to about 4 times the theoretical
value.

I tested it on OMAP4(SMP) blaze board.
