x86: section mismatch fixes, #1

This patch fixes mismatch warnings in smp_checks() (in arch/x86/kernel/smpboot.c):

WARNING: arch/x86/kernel/built-in.o(.text+0x11922): Section mismatch in reference from the function smp_checks()
to the variable .cpuinit.data:smp_b_stepping
The function smp_checks() references
the variable __cpuinitdata smp_b_stepping.
This is often because smp_checks lacks a __cpuinitdata
annotation or the annotation of smp_b_stepping is wrong.

The shutdown status flag set to "0xA", corresponds to "JMP double word
request without INT init".

This JMP at reboot time is at an unintended location. And results in
Triple faults in our case.
Though this error at reboot can be safely ignored in a VM environment,
am not sure what the effect would be on a physical system. May be it
will result in a triple fault and an eventual hardware reset thus
masking this BUG in the kernel.

This fix just makes sure that we reset that status flag after
initialization is done.

Fix paranoia about using BIOS quickboot mechanism.

Make sure that we clear the "shutdown status flag" in the CMOS register
after each CPU is brought up.  This fixes a problem where the "shutdown
status flag" may remain set when a CPU is brought up after booting.

x86: uv fix

Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86: support for new UV apic

UV supports really big systems. So big, in fact, that the APICID register
does not contain enough bits to contain an APICID that is unique across all
cpus.

The UV BIOS supports 3 APICID modes:

- legacy mode. This mode uses the old APIC mode where
  APICID is in bits [31:24] of the APICID register.

- x2apic mode. This mode is whitebox-compatible. APICIDs
  are unique across all cpus. Standard x2apic APIC operations
  (Intel-defined) can be used for IPIs. The node identifier
  fits within the Intel-defined portion of the APICID register.

- x2apic-uv mode. In this mode, the APICIDs on each node have
  unique IDs, but IDs on different node are not unique. For example,
  if each mode has 32 cpus, the APICIDs on each node might be
  0 - 31. Every node has the same set of IDs.
  The UV hub is used to route IPIs/interrupts to the correct node.
  Traditional APIC operations WILL NOT WORK.

In x2apic-uv mode, the ACPI tables all contain a full unique ID (note:
exact bit layout still changing but the following is close):

nnnnnnnnnnlc0cch
n = unique node number
l = socket number on board
c = core
h = hyperthread

Only the "lc0cch" bits are written to the APICID register. The remaining bits are
supplied by having the get_apic_id() function "OR" the extra bits into the value
read from the APICID register. (Hmmm.. why not keep the ENTIRE APICID register
in per-cpu data....)

The x2apic-uv mode is recognized by the MADT table containing:
  oem_id = "SGI"
  oem_table_id = "UV-X"

x86: surround hard_smp_processor_id in APIC_DEFINITION

APIC_DEFINITION is not defined in x86_64, so in practice, we keep
our old code here. But as a nice side effect, the code is now
equal to smp_32.h.

x86: microcode: show results on success too

Report when microcode was successfully updated. It used to be there but
now with DEBUG unset it becomes very silent. Also some cosmetic fixes.

x86: add comments to describe the new api's in cacheflush.h

The new cacheflush.h API's didn't have any comments describing
how they're to be used yet and the conventions around these functions.
This patch adds comments to this effect; in order for that to be
a logical series, some prototypes had to move around.
