There is a thinko in the irq code, it uses IRQ_NONE to indicate no irq,
whereas it should be using NO_IRQ. IRQ_NONE is returned from irq
handlers to say "not handled".
As it happens they currently have the same value (0), so this is just for
future proof-ness.

In the bootwrapper code for powerpc, we include HOSTCFLAGS into the
BOOTCFLAGS used for building the zImage wrapper code. Since the
wrapper code is not host code, this makes no sense. This patch
removes the use of HOSTCFLAGS here, instead including directly into
BOOTCFLAGS those flags from the normal kernel CFLAGS which also make
sense in the bootwrapper code.
In particular, this makes the bootwrapper use -msoft-float, preventing
the compiler from generating floating point instructions. Previously,
under some circumstances the compiler could generate floating point
instructions in the bootwrapper which would cause exceptions on
embedded CPUS which don't have floating point support.

This zImage is really just the stripped vmlinux, but it means that there
is one less special case for iSeries and also that the zImages will be
built for a combined kernel build that happens to include iSeries.
This zImage boots fine on legacy iSeries.

The recent addition of assembler flags for 44x.c and ebony.c in the
bootwrapper to make them compile on certain toolchains was not correct
and could break other platforms. This patch switches to using a
compiler flag instead, which implies the appropriate assembler flag,
and also stops the compiler itself generating instructions which are
invalid for the platform in question.

The ppc32 kernel didn't properly set/clear the TIF_SINGLESTEP
flag, causing return from syscalls to not SIGTRAP, thus executing
one more instruction before stopping again.
This fixes it. The ptrace code is a bit of a mess, and is overdue
for at least a -proper- 32/64 bits split and possibly more cleanups
but this minimum fix should be ok for 2.6.22

Fix the following section mismatch warnings in microcode.c:
WARNING: arch/i386/kernel/built-in.o(.init.text+0x3966): Section mismatch: reference to .exit.text: (between 'microcode_init' and 'parse_maxcpus')
WARNING: arch/i386/kernel/built-in.o(.init.text+0x3992): Section mismatch: reference to .exit.text: (between 'microcode_init' and 'parse_maxcpus')
The warning are caused by a function marked __init that
calls a function marked __exit.
Functions marked __exit may be discarded either during link or run-time
and thus the reference is not good.

a) additions to the systems list and cleanup of same
b) change limits of NR_CPUS and make dep. on platform
Note that MARVEL support is limited to 32 CPUs whan using
42-bit KSEG - one needs 48-bit KSEG to handle up to 64, and
we've never supported 48-bit KSEG.

This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).
An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses. All other machines have the option set FALSE.
A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device. This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.
A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.
Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.

Chuck reports that the recent fix from Andi to oprofile
6c977aad03a18019015035958c65b6729cd0574c introduces a double free. Each
cpu's cpu_msrs is setup to point to cpu 0's, which causes free_msrs to free
cpu 0's pointers for_each_possible_cpu. Rather than copy the pointers, do
a deep copy instead.

Wolfgang gets:
PCI: Cannot allocate resource region 0 of device 0000:00:04.0
PCI: Error while updating region 0000:00:04.0/0 (a8008000 != fec08000)
Note that the BAR seems to have high address bits hardwired to fec00000.
And device 0000:00:04.0 is
00:04.0 System peripheral: Siemens Nixdorf AG FSC Multiprocessor Interrupt Controller (rev 02)
I'd guess that when we try to reassign this resource, PCI interrupts might
just stop working. This could explain SCSI timeouts and other weird things.

The S3C2412 has an reset-errata where the clock
may cause a glitch switching back to EXTCLK. We
force a switch to EXTCLK before writing the
reset register to force use of the CLKCON sync
logic to properly switch.
Fix problem reported by Matthieu Castet.

Fix lockdep warnings, caused by 'set_affinity' being called without
the correct locks taken and local interrupts disabled:

Fix an oops in the stacktrace code, caused by improper range checking.
We subtract 12 off 'fp' before testing to see if it's below the low
bound. However, if 'fp' were zero before, it becomes a very large
positive number, causing this test to succeed where it should fail.

Use the newly introduced __used attribute in place of the deprecated
__attribute_used__. Functionally the same.
