Add initialization of init_sighand for m68knommu architectures.

Otherwise a if one them is partially empty, the following input section
can end up in the wrong place.

On the v850 RTE-MA1-CB-MULTI platform, these are normally intercepted by
the monitor for the use of an external debugger, but if you want to use
a linux-resident debugger, the kernel has to see them.

1) Preserve the v850 system-call-number register when handling a signal;
   otherwise system calls will not be correctly restarted afterwards
2) Correctly handle illegal insn exceptions, which need a special
   instruction to return (not reti), and save PC/PSW to a different place
2) Remove some unnecessary register saving in the trap handler
3) Consolidate various places that use the register save/restore macros
4) Eliminate some unused compile-time configuration stuff
5) A bit of whitespace and other syntactic cleanup

Removes a bunch of unnecessary nops... :-)

Previously the v850's copy_thread function didn't set the child's stack
pointer at all, with the result that it accidentally worked for vfork
(where the child has the same SP as the parent), but not for user
threads; kernel threads also accidentally worked, for a different
reason.

Various overflow problems compiling the lib/idr.c code for ppc64

Patch from William Lee Irwin III <wli@holomorphy.com>

Remove start_lazy_tlb() and end_lazy_tlb(), as they are unused.

Patch from Max Krasnyansky <maxk@qualcomm.com>

This changeset adds module refcounting for TTY line disciplines.  I've sent
the patch to LKM earlier.  No negative comments (actually most people didn't
seem to care).  This is needed at least for Bluetooth and IrDA (Jean is ok
with the patch).

Make the prof_counter and prof_old_counter arrays use per-cpu data, and give
them static scope.

Also fix a signedness bug in the voyager implementation (from James)

Patch from Nikita Danilov <Nikita@Namesys.COM>

this moves functions from identical per-architecture
arch/*/kernel/profile.c into generic kernel/profile.c.  Also, identical
{x86,parisc,ppc64,sparc64}_profile_hook()'s are all replaced by the
single kernel/profile.c:profile_hook(), which is #defined to noop in
include/linux/profile.h if CONFIG_PROFILING is not set.

And finally, attached patch enables visws subarch support
in kernel config.

Patch from Andrey Panin <pazke@orbita1.ru>

Looks like I'm a maintainer of visws support now :))

Patch from Andrey Panin <pazke@orbita1.ru>

This patch contains SGI visws OSS sound driver update.

Patch from Andrey Panin <pazke@orbita1.ru>

This patch contains SGI visws framebuffer update. Patch makes it
compile again and brings flatpanel monitor support back.

Patch from Andrey Panin <pazke@orbita1.ru>

This patch contains core support for visws subarch.

Patch from Andrey Panin <pazke@orbita1.ru>

This patch contains update of pci support for visws.

Patch from Andrey Panin <pazke@orbita1.ru>

This patch adds misiing mach_apic.h file.

Patch from Andrey Panin <pazke@orbita1.ru>

This trivial patch moves visws related header files into asm/mach-visws.

Patch from Andrey Panin <pazke@orbita1.ru>

This simple patch adds some additional code into head.S.

On visws bootup cpu starts in protected mode (so we don't need
setup.S), but setting up pagetables and gdt is required before
running rest of head.S.

Patch from Andrey Panin <pazke@orbita1.ru>

This simple patch exports boottime gdt descriptor from trampoline.S.
Visws uses it to initialize bootup cpu before running the rest of head.S

Patch from Andrey Panin <pazke@orbita1.ru>

This patch marks startup_32 (in head.S) as kernel entry point,
visws kernel loader uses raw elf kernel images and entry point
at stext causes jump to wrong address.

Patch from Andrey Panin <pazke@orbita1.ru>

This trivial patch exports some functions from 8259.c file.
Visws subarch needs them to handle interrupts from legacy devices
connected to PIIX4 i8259s, which are in turn connected to SGI
Cobalt APIC.

Patch from Andrey Panin <pazke@orbita1.ru>

I'm here again, starting another hopeless attempt to submmit
visws subarch support for 2.5. This series of patches was tested
by me and brave people from linux-visws-devel mailing list and
our beloved workstations seem to work well under 2.5.xx.

This patch moves enable_NMI_through_LVT0() function from io_apic.c
to apic.c to allow SMP kernel build without io_apic.c included.

Patch from Stephen Hemminger <shemminger@osdl.org>

Patch from Stephen Hemminger <shemminger@osdl.org>

Patch from Andries.Brouwer@cwi.nl

Remove MAX_BLKDEV from nfsd.

Patch from Dave Hansen <haveblue@us.ibm.com>

The new kirq patch assumes flat addressing APIC mode where apicid = (1
<< cpu).  This isn't true for clustered mode.

 - Change name/type of irq_balance_mask.  The type of apicid seems to
   be int.
 - Change instance of (1<<cpu) to cpu_to_logical_apicid()
 - Don't use target_cpu_mask, use min_loaded, and convert the real way

Tested on Summit, and plain SMP.  Martin Bligh and I figured this out
together, and he agrees.

Patch from Andi Kleen <ak@muc.de>

This simple patch allow me to symlink hugetlbpage.c for x86-64.

CIFS is using these.

Given that the readpages() address_space op is supposed to add the pages to
pagecache, it makes sense to make these functions available to modules.

I can't say that I put a lot of though into the readpages API.  It was
designed as just enough functionality to be able to stuff a bunch of
readahead pages into a single BIO.  The only reason I made it an a_op at all
was because we have toi enter the fs to pick up the ->get_block callback's
address.

But a couple of filesystems seem to be making use of it now.  Reiser4 will
need access at the do_page_cache_readahead() level too.

Patch from Martin Josefsson <gandalf@wlug.westbo.se>

Here's a fix for an uninitialized timer in drm_drv.h, for some reason it
initilizes the timer when the device is opened, not at init.  It moves
the initilization for the waitqueue to init aswell.

Patch from Hugh Dickins <hugh@veritas.com>

2.5.62's removal of scsi_set_pci_device broke the MPT Fusion build.

This provides the following spelling fixes.

 posible  -> possible
 messsage -> message
 reqeuest -> request
 exeption -> exception
 seqeunce -> sequence
 loggger  -> logger
 resposible -> responsible
 qeueu    -> queue
 microsecnds -> microseconds
 positiion -> position
 feilds    -> fields
