x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

x86: prepare time related functions for paravirt This patch add provisions for time related functions so they can be later replaced by paravirt versions. it basically encloses {g,s}et_wallclock inside the already existent functions update_persistent_clock and read_persistent_clock, and defines {s,g}et_wallclock to the core of such functions. it also allow for a later-on-game time initialization, as done by i386. Paravirt guests can set a function to do their own initialization this way.

x86: i8253: Consolidate definitions of global_clock_event There are multiple declarations of global_clock_event in header files specific to particular clock event implementations. Consolidate them in <asm/time.h> and make sure all users include that header.

x86: isolate the rtc code for sharing The mach-default/mach_time.h code inline is moved to arch/x86/kernel/rtc.c and the header files are adjusted. Shrink the 3 dozen includes to the ones we really need. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>

[PATCH] vmi: pit override The time_init_hook in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through an indirect function pointer in the paravirt-ops table. The problem is, by the time the paravirt hook is called, the pit timer is already enabled. But paravirt guests have their own timer, and don't want to use the PIT. Rather than intensify the struggle for power going on here, just make it all nice and simple and just unconditionally do all timer setup in the late_time_init hook. This also has the advantage of enabling timers in the same place in all code paths, so everyone has the same bugs and we don't have outliers who break other code because they turn on timer too early or too late. So the paravirt-ops time init function is now by default hpet_time_init, which is the time init function used for native hardware. Paravirt guests have the chance to override this when they setup the paravirt-ops table, and should need no change.
