Modify the update_wall_time function so it increments time using the clocksource abstraction instead of jiffies. Since the only clocksource driver currently provided is the jiffies clocksource, this should result in no functional change. Additionally, a timekeeping_init and timekeeping_resume function has been added to initialize and maintain some of the new timekeping state.

According to Alan Modra alan@linuxcare.com.au, the -fno-omit-frame-pointer is
needed for x86 only. Why this used to be enabled for all architectures is beyond
me. I suspect most platforms don't need this, but until we know that for sure
I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k
to get a correct value for the wait-channel (WCHAN in ps). --davidm
