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.

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".

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.

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.

In fact, TILO assumes this entry is always at 0x4000, yikes!

2.6.23-rc1 turned up another batch of references from non-__init code to
__init code. In most cases, these were missing __init annotations. In one
case (os_drop_memory), the annotation was present but wrong.
init_maps is __init, but for some reason was being very careful about the
mechanism by which it allocated memory, checking whether it was OK to use
kmalloc (at this point in the boot, it definitely isn't) and using either
alloc_bootmem_low_pages or kmalloc/vmalloc. So, the kmalloc/vmalloc code is
removed.

In 2.6.23-rc1, i386 fiddled its string support such that UML started getting
undefined references from modules. The UML asm/string.h was including the
i386 string.h, which defined __HAVE_ARCH_STR*, but the corresponding
implementations weren't being pulled in.
This is fixed by adding arch/i386/lib/string.h to the list of host
architecture files to be pulled in to UML.
A complication is that the libc exports file assumed that the generic strlen
and strstr weren't in use (i.e. __HAVE_ARCH_STR is defined), then they aren't
exported. This is untrue for strlen, which is exported in either case, so
this logic is not needed.

The interrupts of an E100 card inserted in PCI slot 4 may be on at bootup.
The resulting interrupt flood interacts with the 8259 cascade handler and
prevents proper boot up. There is a quirk for the E100 that will disable
the E100's interrupts but to use it, the 8259 cascade hookup must be
delayed until after the quirk has run. This patch delays the 8259 cascade
hookup by registering a device_initcall() which runs after the PCI quirk
for the E100.
