This fix is from Paul Mackerras and was applied in 2.4 sometime late
last year.

On ppc64, touching addresses between the highest other mapping and the
stack can cause the stack to be extended way, way down, rather than
causing a SEGV as you would expect.  This patch only allows the stack
mapping to be extended to cover addresses actually within the stack
(as determined by looking at the process's r1).  This fix is ported
from 2.4

This fixes failures on the LTP's shmdt01, munmap01 and munmap02 tests.

In ide_init_default_irq() patch I overlooked that ppc_ide_md.init_hwif_ports()
called from generic ide_init_hwif_ports() can set hwif->irq and it will
be overwritten by ide_init_default_irq() if CONFIG_PCI is defined.  Fix
it.

I will clean it up properly later after killing ide_init_hwif_ports() on
ARM{26}.  Doing it now is just wasted effort.

Patch from Dirk Behme

Make ALTERA Excalibur work again in 2.6.4. Update serial driver uart00.c and defconfig.

This is an update of patch 1833/1.

Remove #include <config/pld/hotswap.h>, it isn't necessary at all. 

atomic_dec_and_test and atomic_add_negative didn't mark their
temporary variables as early-clobber.  Fix this.

This allows us to appropriately align shared mappings on VIPT caches
with aliasing issues.

Use named initialisers for monspecs; the format of the structure
changed a while back and it broke.

Use flush_cache_vmap() after creating mappings.  Also use BUG_ON()
rather than if() BUG().

These broke when find_first_bit/find_next_bit was added.

More functions and data that should be static.

Thanks to Dru <andru@treshna.com>, who provided an easy way to reproduce
the problem.

What we have in lib/rwsem.c:__rwsem_do_wake():
	int woken, loop;
	^^^
and several lines below:
	loop = woken;
	woken *= RWSEM_ACTIVE_BIAS-RWSEM_WAITING_BIAS;
	woken -= RWSEM_ACTIVE_BIAS;

However, rw_semaphore->count is 64-bit on Alpha, so
RWSEM_WAITING_BIAS has been defined as -0x0000000100000000L.
Obviously, this blows up in the write contention case.

Fix new ISDN CAPI's internal ncci list semaphore if
CONFIG_ISDN_CAPI_MIDDLEWARE is disabled.

Thanks to Florian Schirmer.

This patch updates support for the Motorola PrPMC750 platform.  Most of the
size in this patch comes from merging prpmc750_pci.c and prpmc750_setup.c into
just prpmc750.c.

This patch adds openpic_hookup_cascade(offset, name, handler) which allows for
an arbitrary interrupt controller to be hooked up as a cascade to the openpic.
 This also allows for platforms to just not have a cascaded controller.

This patch updates support for the SBS K2 platform.  Most of the size in this
