Since GCC has to emit a call and a delay slot to the
out-of-line "membar" routines in arch/sparc64/lib/mb.S
it is much better to just do the necessary predicted
branch inline instead as:
ba,pt %xcc, 1f
membar #whatever
1:
instead of the current:
call membar_foo
dslot
because this way GCC is not required to allocate a stack
frame if the function can be a leaf function.
This also makes this bug fix easier to backport to 2.4.x

We should not restrict use of ieee80211 to only when wireless drivers
are enabled. In-development and out-of-tree drivers may wish to use it,
and by removing this restriction we eliminate a circular dependency.

removal of the get_bh()/put_bh() pairs for each buffer.

Asc2ax was still using a static buffer for all invocations which isn't
exactly SMP-safe. Change asc2ax to take an additional result buffer as
the argument. Change all callers to provide such a buffer.
This one only really is a fix for ROSE and as per recent discussions
there's still much more to fix in ROSE ...

One such place that can damage the dst refcnts is route.c with
CONFIG_IP_ROUTE_MULTIPATH_CACHED enabled, i don't see the user's
.config. In this new code i see that rt_intern_hash is called before
dst->refcnt is set to 1, dst is the 2nd arg to rt_intern_hash.
Arg 2 of rt_intern_hash must come with refcnt 1 as it is added to
table or dropped depending on error/add/update. One such example is
ip_mkroute_input where __mkroute_input return rth with refcnt 0 which
is provided to rt_intern_hash. ip_mkroute_output looks like a 2nd such
place. Appending untested patch for comments and review. The idea is
to put previous reference as we are going to return next result/error.

Fix bug in bnx2_interrupt() that caused an unnecessary register read.
The BNX2_PCICFG_MISC_STATUS should only be read when the status tag
has not changed.
Add prefetch of the status block in bnx2_msi() similar to tg3_msi().
The status block is not touched in bnx2_msi() and prefetching it will
speed up bnx2_poll() that will run on the same CPU that received the
MSI.

access to the allocated size in the ntfs inode with the size lock.
- Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to

zero.
- Fix load_attribute_list() to handle the case of a NULL runlist.

A UDP packet may contain extra data that needs to be trimmed off.
But when doing so, UDP forgets to fixup the skb checksum if CHECKSUM_HW
is being used.
I think this explains the case of a NFS receive using skge driver
causing 'udp hw checksum failures' when interacting with a crufty
settop box.
