This patchs allows the offset to the first page of
physical memory to be on any 2MB boundary
whereas the previous code could only handle psysical
offset to any 16MB boundary (0xNN000000) or any 1MB
boundary below 0x01000000 (e.g. 0x00N00000). The
problem is a consequence of the orr one-byte syntax,
so we fix this and we can place the first bank of
memory at 0x28e00000. I have also included an explicit
check that disallow compilation when PHYS_OFFSET is
not on a 2MiB boundary. head.S would be the proper place
to have this at since this is the first file that
attempts to use PHYS_OFFSET during compile.

The s3c2410_gpio_getcfg() currently returns
a value which is dependant on the GPIO no
passed in. Now we have more generic constants
it is sensible to use those as return codes
so that any function dealing with >1 GPIO
does not need to do it's own number processing.
Since this function is only currently used in
pm.c, it is easy to fixup (and correct pm.c
to use the generic constants)

GPIO bank A can only be output or a special
function, and the regs-gpio.h header has
mistakenly got this as input or output.
The mistake is carried on into the gpio.c
s3c2410_gpio_cfgpin() call which will set the
wrong value if S3C2410_GPIO_OUTPUT is passed.

Cleanup of at91 platform level gpio wake and suspend/resume logic.
The GPIO core now delegates wakeups to the parent AIC by refcounting,
and delegates clock management to the clock API. This makes these
system modules more independent of each other, which is cleaner and will
also help with the AT91SAM9263 (where some GPIO controllers share the
same irq and clock).

SMTC pseudo-interrupts between TCs are deferred and queued if the target
TC is interrupt-inhibited (IXMT). In the first SMTC prototypes, these
queued IPIs were serviced on return to user mode, or on entry into the
kernel idle loop. The INSTANT_REPLAY option dispatches them as part of
local_irq_restore() processing, which adds runtime overhead (hence the
option to turn it off), but ensures that IPIs are handled promptly even
under heavy I/O interrupt load.

Commit f2802e7f571c05f9a901b1f5bd144aa730ccc88e and its x86 version
(b7471c6da94d30d3deadc55986cc38d1ff57f9ca) adds nmi_known_cpu() check
while parsing boot options in x86_64 and i386.
With that, "nmi_watchdog=2" stops working for me on Intel Core 2 CPU
based system.
The problem is, setup_nmi_watchdog is called while parsing the boot
option and identify_cpu is not done yet. So, the return value of
nmi_known_cpu() is not valid at this point.
So revert that check. This should not have any adverse effect as the
nmi_known_cpu() check is done again later in enable_lapic_nmi_watchdog().

The current PDA code, which went in in post 2.6.19 has a flaw in that it
doesn't correctly cycle the GDT and %GS segment through the boot PDA,
the CPU PDA and finally the per-cpu PDA.
The bug generally doesn't show up if the boot CPU id is zero, but
everything falls apart for a non zero boot CPU id. The basically kills
voyager which is perfectly capable of doing non zero CPU id boots, so
voyager currently won't boot without this.
The fix is to be careful and actually do the GDT setups correctly.

It appears that the iommu table address is never stored, and thus
never found, on non-lpar systems. Thus, for example, during boot:
<7>[ 93.067916] PCI: Scanning bus 0001:41
<7>[ 93.068542] PCI: Found 0001:41:01.0 [8086/100f] 000200 00
<7>[ 93.068550] PCI: Calling quirk c0000000007822e0 for 0001:41:01.0
<7>[ 93.069815] PCI: Fixups for bus 0001:41
<4>[ 93.070167] iommu: Device 0001:41:01.0 has no iommu table
<7>[ 93.070251] PCI: Bus scan for 0001:41 returning with max=41
No iommu table? How can that be? Well, circa line 471 of
arch/powerpc/platforms/pseries/iommu.c we see the code:
while (dn && PCI_DN(dn) && PCI_DN(dn)->iommu_table == NULL)
dn = dn->parent;
and a few lines later is the surprising print statement about
the missing table. Seems that this loop ran unto the end, never
once finding a non-null PCI_DN(dn)->iommu_table.
The problem can be found a few lines earlier: it sems that the
value of PCI_DN(dn)->iommu_table is never ever set. Thus, the
patch sets it.
The patch was tested on a Power4 system running in full system
partition mode, which is where I saw the problem. It works; I've
not done any wider testing. Had a brief discussion on this on irc.

The mmio nvram driver (used by cell only atm) isn't properly parsing
the device-tree, meaning that nvram isn't found correctly on the new
Cell blades. It works ok for old blades where the nvram is at the
root of the device tree but fails on Malta and CAB when it's hanging
off axon. This fixes it by using the proper OF parsing functions.

Compiling the kernel with CONFIG_HOTPLUG = y and CONFIG_HOTPLUG_CPU = n
with CONFIG_RELOCATABLE = y generates the following modpost warnings

WARNING: vmlinux - Section mismatch: reference to .init.data: from
.text between '_cpu_up' (at offset 0xc0141c37) and 'cpu_up'
This is because cpu_up, _cpu_up and __cpu_up (in some architectures) are
defined as __devinit
AND
__cpu_up calls some __cpuinit functions.
Since __cpuinit would map to __init with this kind of a configuration,
we get a .text refering .init.data warning.
This patch solves the problem by converting all of __cpu_up, _cpu_up
and cpu_up from __devinit to __cpuinit. The approach is justified since
the callers of cpu_up are either dependent on CONFIG_HOTPLUG_CPU or
are of __init type.
Thus when CONFIG_HOTPLUG_CPU=y, all these cpu up functions would land up
in .text section, and when CONFIG_HOTPLUG_CPU=n, all these functions would
land up in .init section.

Ensure that no SMI interrupts occur between the read of the HPET & TSC
in the clock calibration loop.
I noticed that a 2.66GHz system incorrectly detected the processor
clock speed about 1/7 of the time:
time.c: Detected 2660.005 MHz processor. (most of the time)
time.c: Detected 2988.203 MHz processor. (sometime)
The problem is caused by an SMI interrupt occuring in hpet_calibrate_tsc()
between the read of the HPET & TSC. Prior to switching the BIOS into
ACPI mode, it appears that every 27msec an SMI interrupt occurs. The
SMI interrupt takes 4.8 msec to process.
Note: On my test system, TICK_MIN had to be >380. I picked 5000
to minimize risk of having a value that is too small for other
platforms.

o struct genapic contains pointer to probe() function which is of type

WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt'
o One of the possible options is to put special case check in MODPOST to
not emit warnings for this case but I think it is not a very good option
in terms of maintenance.
o Another option is to make probe() function non __init. Anyway this function
is really small so not freeing this memory after init is not a big deal.
Secondly, from a programming perspective, probably genapic should not
provide pointers to functions which have been freed as genapic is non
__init and is used even after initialization is complete.

o Misc smpboot/cpu hotplug path cleanups. I did those to supress the
warnings generated by MODPOST. These warnings are visible only
if CONFIG_RELOCATABLE=y.
o CONFIG_RELOCATABLE compiles the kernel with --emit-relocs option. This
option retains relocation information in vmlinux file and MODPOST
is quick to spit out "Section mismatch" warnings.
o This patch fixes some of those warnings. Many of the functions in
smpboot case are __devinit type and they in turn accesses text/data which
if of type __cpuinit. Now if CONFIG_HOTPLUG=y and CONFIG_HOTPLUG_CPU=n
then we end up in cases where a function in .text segment is calling
another function in .init.text segment and MODPOST emits warning.

o It also fixes the issues where CONFIG_HOTPLUG_CPU=y and start_secondary()
is calling smp_callin() which in-turn calls synchronize_tsc_ap() which is
of type __init. This should have meant broken CPU hotplug.

The problem was introduced in 2.6.18.3 with the casting of some
36bit-defines (PCI memory) in au1000.h to resource_size_t which may be
u32 or u64 depending on the experimental CONFIG_RESOURCES_64BIT.
With unset CONFIG_RESOURCES_64BIT, the pci-memory cannot be accessed
because the ioremap in arch/mips/au1000/common/pci.c already used the
truncated addresses.
With set CONFIG_RESOURCES_64BIT, things get even worse, because PCI-scan
aborts, due to resource conflict: request_resource() in arch/mips/pci/pci.c
fails because the maximum iomem-address is 0xffffffff (32bit) but the
pci-memory-start-address is 0x440000000 (36bit).
To get pci working again, I propose the following patch:
1. remove the resource_size_t-casting from au1000.h again
2. make the casting in arch/mips/au1000/common/pci.c (it's allowed and
necessary here. The 36bit-handling will be done in __fixup_bigphys_addr).
With this patch pci works again like in 2.6.18.2, the gcc-compile warnings
in pci.c are gone and it doesn't depend on CONFIG_EXPERIMENTAL.

Add wrappers for N32 msg{snd,rcv}. compat_sys_msg{snd,rcv} can not not be
used as system call entries as is. This fix is based on Kaz Kylheku's
patch.
Also change a type of last argument of sysn32_semctl to match its true
size.
