x86: Replace the now identical time_32/64.c by time.c

2009-08-31T07:35:46+00:00

Remove the redundant copy.

x86: time_32/64.c unify profile_pc

2009-08-31T07:35:46+00:00

The code is identical except for the formatting and a useless
#ifdef. Make it the same.

x86: Move calibrate_cpu to tsc.c

2009-08-31T07:35:46+00:00

Move the code where it's only user is. Also we need to look whether
this hardwired hackery might interfere with perfcounters.

x86: Make timer setup and global variables the same in time_32/64.c

2009-08-31T07:35:46+00:00

The timer and timer irq setup code is identical in 32 and 64 bit. Make
it the same formatting as well. Also add the global variables under
the necessary ifdefs to both files.

x86: Remove mca bus ifdef from timer interrupt

2009-08-31T07:35:46+00:00

MCA_bus is constant 0 when CONFIG_MCA=n. So the compiler removes that
code w/o needing an extra #ifdef

x86: Simplify timer_ack magic in time_32.c

2009-08-31T07:35:46+00:00

Let the compiler optimize the timer_ack magic away in the 32bit timer
interrupt and put the same code into time_64.c. It's optimized out for
CONFIG_X86_IO_APIC on 32bit and for 64bit because timer_ack is const 0
in both cases.

x86: Prepare unification of time_32/64.c

2009-08-31T07:35:46+00:00

Unify the top comment and the includes.

x86: Add timer_init to x86_init_ops

2009-08-31T07:35:46+00:00

The timer init code is convoluted with several quirks and the paravirt
timer chooser. Figuring out which code path is actually taken is not
for the faint hearted.

Move the numaq TSC quirk to tsc_pre_init x86_init_ops function and
replace the paravirt time chooser and the remaining x86 quirk with a
simple x86_init_ops function.

cpumask: remove references to struct irqaction's mask field.

2009-03-30T11:35:14+00:00

Impact: cleanup

It's unused, since about 1995.  So remove all initialization of it in
preparation for actually removing the field.

x86: Add IRQF_TIMER to legacy x86 timer interrupt descriptors

2009-02-22T18:27:49+00:00

Right now nobody cares, but the suspend/resume code will eventually want
to suspend device interrupts without suspending the timer, and will
depend on this flag to know.

The modern x86 timer infrastructure uses the local APIC timers and never
shows up as a device interrupt at all, so it isn't affected and doesn't
need any of this.
