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

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

This code should write byte every loop iteration, but last time delay

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.

Uli started this by seeing that UML's initialization of a struct iocb
initialized fields that it shouldn't.
Al followed up by adding the following cleanups:
eliminating a variable by just using an anonymous structure in
its place.
hoisting a duplicated line out of the switch.
simplifying the error checking at the end.

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.

The current 85xxCDS restart code fails to reset the PCI bus which can
lead to odd behavior after the restart. This patch uses the VIA Super
Southbridge to perform a PCI reset which will reset the entire system.
NOTE: Since the VIA chip is behind a PCI-to-PCI bridge which can be
disabled with a switch setting, it may not be possible to perform the
PCI bus reset. In this case, the code defaults to the previous restart
mechanism.

The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy
8259 interrupt controller pair contained within a VIA VT82C686B Southbridge
on the main carrier board. The processor complex plugs into the carrier
card using a PCI slot which limits the available interrupts to the
INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed
through a gate array and connected to the PCI INTA interrupt line.
The normal interrupt chaining hook (set_irq_chained_handler) does
not allow sharing of the chained interrupt which prevents the
use of PCI INTA by PCI devices. This patch allows the 8259 cascade
pair to share their interrupt line with PCI devices.
NOTE: The addition of the .end routine for the MPIC is not strictly
necessary for this patch. It's there so this code will run from within
the threaded interrupt context used by the Real Time patch.
