We currently initialize cbe_spu_info[].spus in both init_spu_base and
spu_sched_init. The initialise in spu_sched_init clears the SPU list,
so we end up with no physical SPUs. Because of this, the spu_run
syscall will block forever.
This change removes the unnecessary initialization in spu_sched_init.

The Maple platform has ISA IOs but didn't call the new functions to

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".

Scan the device tree for i2c devices, check their "compatible" property
against a hard-coded table, and, if found, register with i2c boardinfo.
This provides the infrastructure needed to find i2c devices in the

This and the following commit let the linkstation work with the new i2c

This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e.
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.

Signed-off-by: H. Peter Anvin <hpa@zytor.com>

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.

We can't mark the whole thing init because there are dependencies
in bootloaders that assume that _start, or whatever the image
entry value, is 2 instructions before the "HdrS" signature.
In fact, TILO assumes this entry is always at 0x4000, yikes!
Also, right after the bootloader info area there are OBP strings and
values that get used later in the boot process, and those are not all
provably .init yet.

Sparc optimized memset (arch/sparc/lib/memset.S) does not fill last

address is not word (4-bytes) aligned.
Here is code chunk where bug located:
/* %o0 - memory address, %o1 - size, %g3 - value */
8:
add %o0, 1, %o0
subcc %o1, 1, %o1
bne,a 8b
stb %g3, [%o0 - 1]
This code should write byte every loop iteration, but last time delay
instruction stb is not executed because branch instruction sets
"annul" bit.

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.
