17cd87c26b [POWERPC] Fix Maple platform ISA bus
The Maple platform has ISA IOs but didn't call the new functions to
actually map those, thus crashing when trying to access the nvram.

This fixes Maple and JS2x using SLOF.

50747cb818 [POWERPC] Make pci_iounmap actually unmap things
This patch uses the newly added functions for testing if an address is
an ISA or PCI IO port to properly unmap things in pci_iounmap that
aren't such ports.  Without that, drivers using the iomap API will never
actually unmap resources, which on IBM server machines will prevent
hot-unplug of the corresponding HW adapters.

f5d834fc34 [POWERPC] Fix Pegasos keyboard detection
As of 2.6.22 the kernel doesn't recognize the i8042 keyboard/mouse
controller on the PegasosPPC.  This is because of a feature/bug in the
OF device tree: the "device_type" attribute is an empty string instead
of "8042" as the kernel expects.  This adds a secondary detection
which looks for a device whose *name* is "8042" if there is no device
whose *type* is "8042".

77926826f3 Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"
This reverts commit fd6e9d3945.

Having #size-cells == 0 in a node indicates that things under the
node aren't directly accessible, and therefore we shouldn't try to
translate addresses for devices under the node into CPU physical
addresses.

Some drivers, such as the nvram driver for powermacs, rely on
of_address_to_resource failing if they are called for a node
representing a device whose resources aren't directly accessible
by the CPU.  These drivers were broken by commit fd6e9d39,
resulting in the "Lombard" powerbook hanging early in the boot
process.

cb7e51d8b1 kbuild: fix modpost warnings for xtensa
The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.

The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0
should not cause any regressions for other architectures.

We also need to suppress warnings for two informational
sections (.xt.lit and .xt.prop) used by the Xtensa architecture.

1514ab09ed [x86 setup] APM detection logic bug fix
Starting with kernel 2.6.23-rc1, the i386 APM driver fails
on several of my machines with the message:

apm: BIOS not found

This happens because of a bug in the i386 boot code rewrite
from assembler to C. The original assembly code had the
following code in its APM BIOS presence test (boot/setup.S):

	andw	$0x02, %cx			# Is 32 bit supported?
	je	done_apm_bios			# No 32-bit, no (good) APM BIOS

That is, the code bails out if bit 2 is zero.

In the new C version, this is coded as (boot/apm.c):

	if (cx & 0x02)		/* 32 bits supported? */
		return -1;

Here we see that the test has been accidentally inverted.

The fix is to negate the test. I've verified that this
allows the APM driver to work again on my affected machines.
