H. Peter Anvin	ae7bd11b47	clocksource: Change __ARCH_HAS_CLOCKSOURCE_DATA to a CONFIG option ... The machinery for __ARCH_HAS_CLOCKSOURCE_DATA assumed a file in asm-generic would be the default for architectures without their own file in asm/, but that is not how it works. Replace it with a Kconfig option instead. Link: http://lkml.kernel.org/r/4E288AA6.7090804@zytor.com Signed-off-by: H.

Andy Lutomirski	98d0ac38ca	x86-64: Move vread_tsc and vread_hpet into the vDSO ... The vsyscall page now consists entirely of trap instructions.

Andy Lutomirski	433bd805e5	clocksource: Replace vread with generic arch data ... The vread field was bloating struct clocksource everywhere except x86_64, and I want to change the way this works on x86_64, so let's split it out into per-arch data.
