this is the big move: flip over VISWS to generic arch support.
From this commit on CONFIG_X86_VISWS is just another (default-disabled)
option that turns on certain quirks - no other complications.

copy arch/x86/mach-visws/setup_visws.c, apic_visws.c and traps_visws.c
files to arch/x86/kernel/, in preparation of the switchover to a
non-subarch setup for VISWS.

add early quirk support to the generic architecture code.
this allows VISWS to be supported by the generic code and allows us
to remove the VISWS subarch.

NR_IRQS: let VISWS be just a sub-case of the generic code.
This can create a somewhat larger irq_desc[] array if NR_CPUS is high
but that should not worry VisWS which has 4 CPUs at most.

move the SGIVW definitions from setup_arch.h into its own header file.

move the include/asm-x86/mach-visws/ VISWS specific hardware
details include files into include/asm-x86/visws, to be used from
generic code.
No code changed.

update asm-x86/mach-visws/mach_apicdef.h to the generic version.
This should work fine as VISWS has a standard local APIC and thus
its mach_apicdef.h copy is just an ancient version of the generic code.

now that include/asm-x86/mach-visws/smpboot_hooks.h equals
to the default file in ../mach-default/smpboot_hooks.h, simply
include it instead of maintaining a copy.

update include/asm-x86/mach-visws/smpboot_hooks.h to
include/asm-x86/mach-default/smpboot_hooks.h (the generic version).
this _should_ work, because VISWS sets skip_ioapic_setup, but it
should be tested on a real VISWS to make sure.

Allow the generic smpboot quirks code to be built with
ONFIG_X86_IO_APIC disabled. This way VISWS will be able
to use it as-is.

first step: make the VISWS subarch boot on a regular PC.
We take various shortcuts for that. We copy the generic arch setup file over
into the VISWS setup file.
This is the only step that is not expected to boot on a real VISWS.

Add early quirks support.
In preparation of enabling the generic architecture to boot on a VISWS.
This will allow us to remove the VISWS subarch and all its complications.

The stack-glue merge changed the way we use flags in dlmglue in that we now
use the fs/dlm equivalents. Unfortunately, a merge error left the new flock
code only partially updated. This took a while to show up though, because
the lock level constants are actually identical between o2dlm and fs/dlm.
The *_CONVERT and *_NOQUEUE flags have different values though, which is
eventually causing a crash in flags_to_o2dlm().

Since it had various regions to be loaded to separate addresses, and it
wanted to do them in fairly small chunks anyway, switch it to use the
new ihex code. Encode the start address in the first record.
