Bob Breuer wrote a patch to add dump_stack for sparc. Supposedly, this
was applied, but it doesn't exist in 2.6.11.
This is the same patch, rediffed against 2.6.11.

Peter Jones uncovered this one while we were debugging the framebuffer
issues. There are some references to -1 in the mxcc asm code, which
should be 0xffffffff.
This patch gets rid of the -1s.

The sparc32 ksyms is missing a few more symbols, these are primarily
related to SMP, and will be needed as SMP gets beaten back into
functionality.
Specifically, add __cpu_data (PER_CPU), cpu_online_map, and
phys_cpu_present_map.
This patch assumes that the earlier "linux-2.6.11-sparc-fixksyms.patch"
is applied, otherwise, it will apply with fuzz.

Using the same logic as the other framebuffer fixes committed in 2.6.11,
this is a set of fixes to make TCX functional on the console again. Adds
the tcx_pan_display function, sets the
all->info.var.{red,green,blue}.length values to 8, and runs fb_set_cmap.
Also looks for the correct SUNW,tcx prom value.
This patch just slipped through the cracks.

This patch is incredibly trivial, but it does resolve some of the user
confusion as to what "L1-A" actually is.

Calculate hashtable size to fit into a page instead of a hardcoded
256 buckets hash table. Results in a 1024 buckets hashtable on
most systems.
Replace old naive extract-8-lsb-bits algorithm with a better
algorithm xor'ing 3 or 4 bit fields at the size of the hashtable
array index in order to improve distribution if the majority of
the lower bits are unused while keeping zero collision behaviour
for the most common use case.
Thanks to Wang Jian <lark@linux.net.cn> for bringing this issue
to attention and to Eran Mann <emann@mrv.com> for the initial
idea for this new algorithm.

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect
length final argument. However, the length argument turns out
to be superfluous.
I was just reading ipv6_skip_exthdr and it occured to me that we can
get rid of len altogether. The only place where len is used is to
check whether the skb has two bytes for ipv6_opt_hdr. This check
is done by skb_header_pointer/skb_copy_bits anyway.
Now it might appear that we've made the code slower by deferring
the check to skb_copy_bits. However, this check should not trigger
in the common case so this is OK.

The problem is that when doing MTU discovery, the too-large segments in
the write queue will be calculated as having a pcount of >1. When
tcp_write_xmit() is trying to send, tcp_snd_test() fails the cwnd test
when pcount > cwnd.
The segments are eventually transmitted one at a time by keepalive, but
this can take a long time.
This patch checks if TSO is enabled when setting pcount.

The NAT changes in 2.6.11 changed the position where helpers
are called and perform packet mangling. Before 2.6.11, a NAT
helper was called before the packet was NATed and had its
sequence number adjusted. Since 2.6.11, the helpers get packets
with already adjusted sequence numbers.
This breaks sequence number adjustment, adjust_tcp_sequence()
needs the original sequence number to determine whether
a packet was a retransmission and to store it for further
corrections. It can't be reconstructed without more information
than available, so this patch restores the old order by
calling helpers from a new conntrack hook two priorities
below ip_conntrack_confirm() and adjusting the sequence number
from a new NAT hook one priority below ip_conntrack_confirm().
