Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] Time: i386 Conversion - part 3: Enable Generic Timekeeping This converts the i386 arch to use the generic timeofday subsystem. It enabled the GENERIC_TIME option, disables the timer_opts code and other arch specific timekeeping code and reworks the delay code. While this patch enables the generic timekeeping, please note that this patch does not provide any i386 clocksource. Thus only the jiffies clocksource will be available. To get full replacements for the code being disabled here, the timeofday-clocks-i386 patch will needed.
