x86: wrap MCA_bus test around an ifdef

2008-10-13T08:21:47Z

Only test for MCA_bus if support for MCA is compiled in. Also, for x86_64, write the code inside the conditional for consistency with i386. It won't bite us, since it'll probably never select CONFIG_MCA anyway. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: replace hardcoded number

2008-10-13T08:21:44Z

Replace "4" in time_32.c code by sizeof(long). This way, it can work on x86_64 too. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: coalesce tests

2008-10-13T08:21:25Z

Coalesce v8086_mode and user_mode into a single user_mode_vm() test. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: use user_mode macro

2008-10-13T08:21:23Z

Instead of using SEGMENT_IS_KERNEL_CODE, use the "user_mode" macro, which can play the same role. Delete the former, since it now lacks any user. Signed-off-by: Glauber Costa Signed-off-by: Ingo Molnar

x86: time_XX.c declare functions before they get used

2008-07-22T12:36:01Z

Declare time_init() in asm-x86/time.h Also did cleanup in asm-x86/timer.h : timer_ack is only required for X86_32 int recalibrate_cpu_khz(void) is for X86_32 Signed-off-by: Jaswinder Singh

x86: add ->pre_time_init to x86_quirks

2008-07-20T07:25:52Z

so NUMAQ can use that to call numaq_pre_time_init() This allows us to remove a NUMAQ special from arch/x86/kernel/setup.c. (and paves the way to remove the NUMAQ subarch) Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar

x86: merge sched_clock handling

2008-07-09T05:43:25Z

Move the basic global variable definitions and sched_clock handling in the common "tsc.c" file. - Unify notsc kernel command line handling for 32 bit and 64bit. - Functional changes for 64bit. - "tsc_disabled" is updated if "notsc" is passed at boottime. - Fallback to jiffies for sched_clock, incase notsc is passed on commandline.

x86: I/O APIC: AEOI timer acknowledgement clean-ups

2008-07-08T07:12:53Z

The code that used to be in do_slow_gettimeoffset() that relied on the IRR bit of the master 8259A PIC for IRQ0 to check the state of the output timer 0 of the PIT is no longer there. As a result, there is no need to use the POLL command to acknowledge the timer interrupt in the "8259A Virtual Wire", except for the NMI watchdog when the i82489DX APIC is used (this is because this particular APIC treats NMIs as level-triggered and keeping the input asserted would keep motherboard NMI sources held off for too long). Remove the unneeded bits and adjust comments accordingly. Signed-off-by: Maciej W. Rozycki Signed-off-by: Ingo Molnar

proper extern for late_time_init

2008-04-29T15:06:03Z

Add a proper extern for late_time_init in include/linux/init.h Signed-off-by: Adrian Bunk Acked-by: Ingo Molnar Cc: Thomas Gleixner Cc: john stultz Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

x86: rename the struct pt_regs members for 32/64-bit consistency

2008-01-30T12:30:56Z

We have a lot of code which differs only by the naming of specific members of structures that contain registers. In order to enable additional unifications, this patch drops the e- or r- size prefix from the register names in struct pt_regs, and drops the x- prefixes for segment registers on the 32-bit side. This patch also performs the equivalent renames in some additional places that might be candidates for unification in the future. Signed-off-by: H.
