Linus Torvalds 7a932e5702 asm-generic: cross-architecture timer cleanup
This cleans up two ancient timer features that were never completed in
 the past, CONFIG_GENERIC_CLOCKEVENTS and CONFIG_ARCH_USES_GETTIMEOFFSET.
 
 There was only one user left for the ARCH_USES_GETTIMEOFFSET variant
 of clocksource implementations, the ARM EBSA110 platform. Rather than
 changing to use modern timekeeping, we remove the platform entirely as
 Russell no longer uses his machine and nobody else seems to have one
 any more.
 
 The conditional code for using arch_gettimeoffset() is removed as
 a result.
 
 For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms
 not using clockevent drivers: parisc, ia64, most of m68k, and one
 Arm platform. These all do timer ticks slighly differently, and this
 gets cleaned up to the point they at least all call the same helper
 function. Instead of most platforms using 'select GENERIC_CLOCKEVENTS'
 in Kconfig, the polarity is now reversed, with the few remaining ones
 selecting LEGACY_TIMER_TICK instead.
