Subject: clockevents: Use u32 for mult and shift factors
X-Git-Tag: v2.6.33-rc1~363^2~13

clockevents: Use u32 for mult and shift factors

The mult and shift factors of clock events differ in their data type
from those of clock sources for no reason. u32 is sufficient for
both. shift is always <= 32 and mult is limited to 2^32-1 to avoid
64bit multiplication overflows in the conversion.

Preparatory patch for a generic mult/shift factor calculation
function.
