afc7d20c84 x86 PAT: consolidate old memtype new memtype check into a function
Impact: cleanup

Move the new memtype old memtype allowed check to header so that is can be
shared by other users. Subsequent patch uses this in pat.c in remap_pfn_range()
code path. No functionality change in this patch.

The _OSC capability OSC_EXT_PCI_CONFIG_SUPPORT is set when the root
bridge is added with pci_acpi_osc_support() if we can access PCI
extended config space.

This adds the function pci_ext_cfg_avail which returns true if we can
access PCI extended config space (offset greater than 0xff). It
currently only returns false if arch=x86 and raw_pci_ext_ops is not set
(which might happen if pci=nommcfg is set on the kernel command-line).

14d7ca5c57 x86: attempt reboot via port CF9 if we have standard PCI ports
Impact: Changes reboot behavior.

If port CF9 seems to be safe to touch, attempt it before trying the
keyboard controller.  Port CF9 is not available on all chipsets (a
significant but decreasing number of modern chipsets don't implement
it), but port CF9 itself should in general be safe to poke (no ill
effects if unimplemented) on any system which has PCI Configuration
Method #1 or #2, as it falls inside the PCI configuration port range
in both cases.  No chipset without PCI is known to have port CF9,
either, although an explicit "pci=bios" would mean we miss this and
therefore don't use port CF9.  An explicit "reboot=pci" can be used to
force the use of port CF9.

This patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller
DeviceIDs.

The LPC Controller ID is set by Firmware within the range of
0x3b00-3b1f.  This range is included in pci_ids.h using min and max
values, and irq.c now has code to handle the range (in lieu of 32
additions to a SWITCH statement).

The SMBus Controller ID is a fixed-value and will not change.

011fec7486 Un-break printk strings in x86 PCI probing code
Breaking lines due to some imaginary problem with a long line length is
often stupid and wrong, but never more so when it splits a string that
is printed out into multiple lines.  This really ended up making it much
harder to find where some error strings were printed out, because a
simple 'grep' didn't work.

I'm sure there is tons more of this particular idiocy hiding in other
places, but this particular case hit me once more last week. So fix it.

b460947211 Revert "x86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3"
This reverts commit a2bd7274b4.

It wasn't really right to begin with (there's a better fix for the
problem with e820 reservations clashing with PCI BAR's pending), but it
also actually causes more regressions, so it should be reverted even
before the better fix is finalized.

Rafael reports that this commit broke AHCI detection, and thus causes
the kernel to not boot on his quad core test box.

a2bd7274b4 x86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3
David Witbrodt tracked down (and bisected) a hpet bootup hang on his
system to the following problem: a BIOS bug made the hpet device
visible as a generic PCI device. If e820 reserved entries happen to
be registered first in the resource tree [which v2.6.26 started doing],
then the PCI code will reallocate that device's BAR to some other
address - breaking timer IRQs and hanging the system.

( Normally hpet devices are hidden by the BIOS from the OS's PCI
  discovery via chipset magic. Sometimes the hpet is not a PCI device
  at all. )

Solve this fundamental fragility by making non-PCI platform drivers
insert resources into the resource tree even if it overlaps the e820
reserved entry, to keep the resource manager from updating the BAR.

Also do these checks for the ioapic and mmconfig addresses, and emit
a warning if this happens.

Dump all the PIC, local APIC and I/O APIC information at the

Make the interface of all the functions involved consistent between 32-bit
and 64-bit versions and make them all static by default by the means of a
New-and-Improved(TM) __apicdebuginit() macro.

 Note that like print_IO_APIC() all these only output anything if
"apic=debug" has been passed to the kernel through the command line.
