Help need to clean up udelay() for several ARM CPUs

Hi Guys,

I'm trying to cleanup the old timer API as much as possible in preparation for the new API. I've managed to purge reset_timer() for all but Nios2 as well as get_timer(). Where timer_init() was calling set_timer() or reset_timer() I folded the code into timer_init()

I have then proceeded to do the same to reset_timer_masked() - Mostly this was only called by reset_timer() which in turn was only called by timer_init(), but the following 8 files have reset_timer_masked() used in udelay()

arch/arm/cpu/arm926ejs/omap/timer.c
arch/arm/cpu/arm926ejs/versatile/timer.c
arch/arm/cpu/arm1136/omap24xx/timer.c
arch/arm/cpu/arm1136/mx35/timer.c
arch/arm/cpu/arm920t/a320/timer.c
arch/arm/cpu/armv7/s5p-common/timer.c
arch/arm/cpu/lh7a40x/timer.c
board/armltd/vexpress/ca9x4_ct_vxp.c

Now I'm sure something very funky is going on which allows udelay() to call reset_timer_masked() with impacting on get_timer() but I don't know ARM at all and I'm not willing to mess around with these for fear of causing a rather large breakage.

Can someone please look into these and let me know how I can safely sanitise these 8 implementations of udelay()?

If all else fails, I'll just make reset_timer_masked static in these files

Thanks in advance
