Ivan Kokshaysky 5f7dc5d750 alpha: fix RTC on marvel ... Unlike other alphas, marvel doesn't have real PC-style CMOS clock hardware - RTC accesses are emulated via PAL calls. Unfortunately, for unknown reason these calls work only on CPU #0. So current implementation for arbitrary CPU makes CMOS_READ/WRITE to be executed on CPU #0 via IPI. However, for obvious reason this doesn't work with standard get/set_rtc_time() functions, where a bunch of CMOS accesses is done with disabled interrupts. Solved by making the IPI calls for entire get/set_rtc_time() functions, not for individual CMOS accesses. Which is also a lot more effective performance-wise. The patch is largely based on the code from Jay Estabrook. My changes: - tweak asm-generic/rtc.h by adding a couple of #defines to avoid a massive code duplication in arch/alpha/include/asm/rtc.h; - sys_marvel.c: fix get/set_rtc_time() return values (Jay's FIXMEs). NOTE: this fixes *only* LIB_RTC drivers. Legacy (CONFIG_RTC) driver wont't work on marvel. Actually I think that we should just disable CONFIG_RTC on alpha (maybe in 2.6.30?), like most other arches - AFAIK, all modern distributions use LIB_RTC anyway.
