Results for omap4 sdp build:
Build machine: Intel Core i5 2.5 GHz, 3M cache, 4GB DDR3

Un-modified HEAD:
real	0m21.463s
user	0m31.278s
sys	0m9.281s

With only Wolfgang's patch:
real	0m11.226s
user	0m23.937s
sys	0m4.200s

With only Daniel's patch:
real	0m10.842s
user	0m21.725s
sys	0m2.532s

With both patches:
real	0m8.306s
user	0m21.201s
sys	0m2.408s

Looks like both patches are helping. Thanks!!
