93fc07b434 Virtualize pci_remap_msi_irq() call from general MSI code. It allows MSI
(FSB interrupts) to be used by non-PCI devices, such as HPET.

ae834fc9ba Do not disable edge-triggered interrupts before migration. DELAY() with
interrupt disabled highly probable causes interrupt loss.

b9cd2f771a Move the MD support for PCI message signalled interrupts to the x86 tree
as it is identical for i386 and amd64.

58ccad7ddc Add support for corrected machine check interrupts. CMCI is a new local
APIC interrupt that fires when a threshold of corrected machine check
events is reached.  CMCI also includes a count of events when reporting
corrected errors in the bank's status register.  Note that individual
banks may or may not support CMCI.  If they do, each bank includes its own
threshold register that determines when the interrupt fires.  Currently
the code uses a very simple strategy where it doubles the threshold on
each interrupt until it succeeds in throttling the interrupt to occur
only once a minute (this interval can be tuned via sysctl).  The threshold
is also adjusted on each hourly poll which will lower the threshold once
events stop occurring.

dbd55f3ff0 - Implement MI helper functions, dividing one or two timer interrupts with
arbitrary frequencies into hardclock(), statclock() and profclock() calls.
Same code with minor variations duplicated several times over the tree for
different timer drivers and architectures.
- Switch all x86 archs to new functions, simplifying the code and removing
extra logic from timer drivers. Other archs are also welcome.

ad384d144a Restore different APIC init orders for i386 and amd64 unified in r208452.
Seems noone of them contents both arch for different reasons.

17586b1af8 Default the machdep.lapic_allclocks to be enabled in order to cope with
broken atrtc.
Now if you want more correct stats on profhz and stathz it may be
disabled by setting to 0.

306c0c6ea0 Improving the clocks auto-tunning by firstly checking if the atrtc may be
correctly initialized and just then assign to softclock/profclock.
Right now, some atrtc seems reporting strange diagnostic error* making the
current pattern bogus.

In order to do that cleanly, lapic_setup_clock(), on both ia32 and amd64,
now accepts as arguments the desired sources to handle, and returns the
actual ones (LAPIC_CLOCK_NONE is forbidden because otherwise there is no
meaning in calling such function).
This allows to bring out into commont x86 code the handling part for
machdep.lapic_allclocks tunable, which is retained.

3258030144 Introduce the new kernel sub-tree x86 which should contain all the code
shared and generalized between our current amd64, i386 and pc98.

This is just an initial step that should lead to a more complete effort.
For the moment, a very simple porting of cpufreq modules, BIOS calls and
the whole MD specific ISA bus part is added to the sub-tree but ideally
a lot of code might be added and more shared support should grow.
