The wrong address was being used to write the SCIR led regs on remote
hubs. Also, there was an inconsistency between how BIOS and the kernel
indexed these regs. Standardize on using the lower 6 bits of the APIC
ID as the index.
This patch fixes the problem of writing to an errant address to a
cpu # >= 64.

We were shifting the Ks/Kp/N bits one bit too far on mtsrin. It took
me some time to figure that out, so I also put in some debugging and a
comment explaining the conversion.
This fixes current OpenBIOS boot on PPC64 KVM.

Len Brown pointed out that allmodconfig is broken for
ia64 because of:
arch/ia64/kvm/vmm.c: In function 'vmm_spin_unlock':
arch/ia64/kvm/vmm.c:70: error: 'spinlock_t' has no member named 'raw_lock'
KVM has it's own spinlock routines. It should not depend on the base kernel
spinlock_t type (which changed when ia64 switched to ticket locks). Define
its own vmm_spinlock_t type.

The invlpg prefault optimization breaks Windows 2008 R2 occasionally.
The visible effect is that the invlpg handler instantiates a pte which
is, microseconds later, written with a different gfn by another vcpu.
The OS could have other mechanisms to prevent a present translation from
being used, which the hypervisor is unaware of.
While the documentation states that the cpu is at liberty to prefetch tlb
entries, it looks like this is not heeded, so remove tlb prefetch from
invlpg.

This fixes a "start_kernel(): bug: interrupts were enabled early".
rtc_cmos now takes care of initializing the ISA RTC and reading the

off/online cycle"
This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425. It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.
As Rafael says:
"... it causes microcode_init_cpu() to be called during resume even for
CPUs for which there's no microcode to apply. That, in turn, results
in executing request_firmware() (on Intel CPUs at least) which doesn't
work at this stage of resume (we have device interrupts disabled, I/O
devices are still suspended and so on).
If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
known to us" , so before commit 9f15226e755 microcode_resume_cpu() was
called for all CPUs already in the system during suspend, which was
the right thing to do. The commit changed it so that the CPUs without
microcode to apply are now treated as "unknown", which is not quite
right.
The problem this commit attempted to solve has to be handled
differently."

using smp_call_function_any()
Presently acpi-cpufreq will perform the MSR read on the first CPU in the
mask. That's inefficient if that CPU differs from the current CPU.
Because we have to perform a cross-CPU call, but we could have run the
rdmsr on the current CPU.
So switch to using the new smp_call_function_any(), which will perform the
call on the current CPU if that CPU is present in the mask (it is).

On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.
The PMNC_D bit should not be set, this patch fixes it.

The only thing arch-specific about calling _PDC is what bits get
set in the input obj_list buffer.
There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

The kbuild's select command doesn't propagate through the config
dependencies.
Hence the current rules of hardware breakpoint's config can't
ensure perf can never be disabled under us.
We have:
config X86
selects HAVE_HW_BREAKPOINTS
config HAVE_HW_BREAKPOINTS
select PERF_EVENTS
config PERF_EVENTS
[...]
x86 will select the breakpoints but that won't propagate to perf
events. The user can still disable the latter, but it is
necessary for the breakpoints.
What we need is:
- x86 selects HAVE_HW_BREAKPOINTS and PERF_EVENTS
- HAVE_HW_BREAKPOINTS depends on PERF_EVENTS
so that we ensure PERF_EVENTS is enabled and frozen for x86.
This fixes the following kind of build errors:
