sn_pci_init was unconditionally scanning 255 PCI busses, even though
only a few are actually present on most systems.  This patch adds a
check to make sure a given bus exists before doing the scan, which
saves a little memory and also makes /sys/devices reflect reality a
bit more closely.

On sn2, dma_mapping_error is trivial.  pci_map_single was already returning 0 
in case of failure (0 is an invalid DMA address on sn2), so make 
dma_mapping_error check for that.

irq_stat isn't needed anymore since its members got rolled into
thread_info.preempt_count.

Add missing newline to kernel version of NULL-pointer message and also print
the address while we're at it.

Stephane made some measurements on the access-pattern of the cpuinfo_ia64
members and based on those results, this patch reorganizes the structure
for better cache-line sharing.

I tried to build usb/gadget/file_storage.c (CONFIG_USB_FILE_STORAGE=y),
but it uses "handle_exception()" for its own purposes, which conflicts
with the ia64 definition.  ia64 only uses handle_exception() within
arch code, so it seems like we ought to rename it to be ia64-specific.
done_with_exception() looks similar, so I renamed it as well, although
there's no actual conflict.

This fixes a bug in the swapcontext system call on ppc32.

On ppc32, the system call entry only saves the volatile registers,
except in the case of a few system calls (e.g.  fork) which need all the
registers saved.  Swapcontext needs all the registers but we weren't
saving them all. So fixes that.

At the moment, ppc32 kernels will oops if a threaded program tries to
dump core.  We call dump_fpu with a NULL regs pointer, which it tries
to dereference.

This fixes the issue by implementing the hooks used in doing threaded
core dumps properly.

This important fix checks the SAl *revision* rather than
the *version*.  I carefully documented which was which, then used the
wrong one.

This fixes the display of the boot messages on the BMAC driver (pmac
only).  It used to be messed up in 2.6

In the long story of "BenH can't get a simple fix right the first time",
please add this one to pmac_zilog, and now people should enjoy really
working sleep again on pmac laptops ...

If the serial port was closed, we could use an uninitialized "pwr_delay"
and pass that to schedule_timeout().

This patch against 2.6.5-rc2 affects the SGI/SN platform only. It deprecates
a kernel daemon for our interconnect traffic statistics which has been
replaced by a userland tool.

Mainly cosmetic, but Bjorn noticed I got a little over zealous in
cleaning out the sx1000 specific init routines in sba_iommu.  This adds
back in the ID->name mapping so it doesn't show up as "Unknown".

Bjorn pointed out that the sn console driver will spew printks if
compiled in even if no hardware is present.  In addition to fixing
that, I took the opportunity to cleanup/correct a few other printks in
that driver.

sn_oemdata_* variables must only be used under the sn_oemdata_mutex.

We're getting namespace collisions from the new dma_error(), and it wasn't a
well-chosen identifier.  Rename it to dma_mapping_error().

This is a temporary fix, pending fuller TGA updates.

    drivers/video/tgafb.c is missing a include, complaining about
    color_table[] and others not being defined.

just a small patch to fix a typo.

From: Petr Baudis <pasky@ucw.cz>

This patch fixes a bug which I hit when migrating from 2.4.  Basically,
when I do setfont during the system boot, the then-spawned ttys do not
retain the new font but fall back to the default one.

I've tracked that down to a clearly bogus test in fbcon_set_display(),
because vc->vc_font.width is not set at that time yet (no font has been
loaded for the new vc).  But even if it would (or this was meant to test
against tmp->vc_font.width), it would mean only *HUGE* fonts would be
retained.  And even if there were *two* bugs there and it was supposed to
be less-than there, I couldn't make a sense of the test.

A change which was recently applied to fs/proc/proc_misc.c included a comment
about splitting a seq_printf into two pieces to work around a bug in
gcc-2.95.3.  Unfortunately gcc-2.96 still chokes on the statements.  The
patch below makes it work better and tidies the code up a bit.

This is the rest of the sh update, which includes everything else
sh-specific, general cleanups, bugfixes, etc.  Nothing really eventful.

From: Paul Mundt <lethal@linux-sh.org>

This includes sh-specific framebuffer updates, including updates to hitfb and
pvr2fb, as well as adding sh to the pgprot_writecombine() users in fb_mmap().

From: Paul Mundt <lethal@linux-sh.org>

This implements hugetlb support for SH-4.  SH-4 supports 1k/4k/64k/1MB pages,
since we're only interested in the 64k/1MB sizes, this is what we support.

The sh hugetlbpage code borrows heavily off of the sparc64 port, which works
fine for these cases at this point in time.

From: Paul Mundt <lethal@linux-sh.org>

This implements the DMA mapping API for sh, as well as cleaning up some
sh-specific DMA drivers.

From: Paul Mundt <lethal@linux-sh.org>

SuperH DAC OSS driver.

From: Paul Mundt <lethal@linux-sh.org>

This ports the sh-sci driver to the new API.  sh and h8 both use this.  The
intention is to leave the drivers/char sh-sci in place for a short period of
time until all the h8 people are on the new driver (sh no longer uses the
drivers/char version).

From: Paul Mundt <lethal@linux-sh.org>

This patch updates the sh defconfigs to use the board_defconfig format
instead of the defconfig-board format that sh was using before.  Since Sam
Ravnborg already added the automated archhelp stuff that sh was using to the
top-level Makefile, the sh version can be killed off.

From: Stephen Rothwell <sfr@canb.auug.org.au>

This patch starts cleaing up (and paring down) the virtual console driver. 
It does:

- viocons is NOT a serial driver

- remove unneeded empty methods

- change the console name

From: Stephen Rothwell <sfr@canb.auug.org.au>

This patch stops an oops caused by certain ioctls being performed on the
virtual cdrom.  In particular, the eject and tray close operations were
affected.

From: Paul Mackerras <paulus@samba.org>

This adds __kcrctab to the discard list for the link script for the boot
wrapper, and is needed if you compile with CONFIG_MODVERSIONS.

With this patch applied, we need to update makefile dependencies.  Otherwise
the bootfiles will remain untouched because they do not depend on the changed
linker script.
