SN code has a "modules" variable that conflicts with a variable of the
same name in kernel/module.c.  This conflict breaks lcrash for ia64.
Rename "modules" to "sn_modules".

Certain IA-32 applications which do mmap/munmaps which are not
PAGE_SIZE aligned could see temporary (recovered at process exit time)
memory leaks, because the kernel didn't have enough data to decide if
the complete page could be unmapped. This patch adds a new data
structure called the "partial page list" which helps the kernel keep
track of precisely which 4k pages are in use by the IA-32 application.

Armed with this data, the kernel can make better decisions at munmap
and mprotect time. No significant performance degradation was observed
in the workloads we tested and in some cases, the performance actually
improved!  This is possibly due to the reduced length of the vma list.

The patch below removes the config option and one bit of code for
McKinley A0/A1 CPU workarounds.  These CPUs were never used in
production, and IIRC this workaround really only affected X11.

When handling FBIOPUTCMAP_SPARC, sbusfb fails to initialize cmap.transp,
which quickly leads to an oops when fb_set_cmap() dereferences it.

First encountered in Aurora Wombat kernels and seems to afflict mainline
as well. Patch is against 2.6.7-rc2. xorg still fails to actually get
anything to display on my CG6, but at least it no longer oopses the kernel.

This entry in the DMI blacklist table is missing it's NO_MATCH
tags, which means the struct gets padded instead of filled with
the desired NO_MATCH data which is {255, NULL}

Usually not fatal it seems, but there have been numerous cases
in Red Hat bugzilla where this did get tripped up, and caused
an immediate reset on these boards. Not fun to track down.

Adds a dummy flush_tlb_page_nohash() called by ptep_set_access_bits(),

ARGH. Missed one file. Here is an additional patch (missed tlbflush.h patch)

Sorry.

This adds the definiction of flush_tlb_page_nohash() that was missing
from the previous patch fixing SW-TLB loaded PPCs

The recent introduction of ptep_set_access_flags() with the optimisation
of not flushing the TLB unfortunately broke ppc32 CPUs with no hash
table.

The data access exception code path in assembly for these doesn't
properly deal with the case where the TLB entry is present with the
wrong PAGE_RW and will just call do_page_fault again instead of just
replacing the TLB entry.

Fixing the asm code for all the different CPU types affected (yah,
embedded PPCs all have different MMUs =P) is painful and need testing I
can't do at the moment, so here's a fix that will just flush the TLB
page when changing the access flags on non-hash based machines.  Please
apply.

The scheduler changes had another thing missing: the appreciation of
sync wakeups.  (I had this in one of the earlier sched-domains cleanup
patches before but it got lost in the shuffle.)

When a sync waker is waking, we should subtract its load from the
current load - it will schedule away for sure in the near future. 
That's what the "sync" bit means.

This change is necessary because with the sched-domains balancer we have
a much more sensitive cpu-load estimator, and in this particular context
of try_to_wake_up() the sync waker's effect will always be part of the
load.  Patch against your patch attached. 

In my testing there's an additional increase in bw_pipe numbers on a
dual P2 box, it went from 110-120 MB/sec to 120-130 MB/sec.

Lets just remove it. It's been disabled some time ago, and there's no
