Revert "scheduler: compute time-average nr_running per run-queue - original code from NVIDIA - this is used to detect avg_running load on the generic hotplug driver and the GPU clocks decisions."

This reverts commit a25cf8793f55e63a480574b01113df403577c559.
Revert "Fix derp from latest commit."

Revert "arm: Move to upstream udelay via timer implementation"

This reverts commit 1bacb4f838661d042207c9186870f0b3586fab05.
Revert "binfmt_elf.c: use get_random_int() to fix entropy depleting. Original commit: https://patchwork.kernel.org/patch/1745611/"

This reverts commit d8620109360bb51ddc4a7759cd70f48c01a3ab68.
Revert "auto_hotplug.c: this device boots up faster than any other so we can start the hotplug works sooner - sometimes the previous 20 seconds timer started exactly when I started to swipe the App Drawer after the device was booted and that would create a 1 time lag and that was annoying every time I rebooted. Should be ok now."

This reverts commit 5dea4777e62df79833e33de2cd7a3507635b714e.
auto_hotplug.c: since the sampling rate was adjusted a few patches ago I never got to update the timers in the delayed works to be according the new rate and the more sampling periods. Should be more snappy now when the device needs the extra processing power, without sacrificing battery. Also added contact info in the top of the file and more info regarding OMAP4460.
