[NET]: Add new sysfs attribute 'carrier' for net devices.
From: Jesper Juhl <juhl-lkml@dif.dk>
The patch adds a new sysfs attribute called carrier for net devices that
exposes the result of netif_carrier_ok(). This allows a user to quickly
and easily determine if a given netdevice has carrier or not. Reading
/sys/class/net/<interface>/carrier yields a '1' when there is a carrier and
a '0' when there is not.

Module removal can call death_by_timeout() manually, which isn't in softirq

the simplest workaround is to call CONNTRACK_STAT_INC() inside the lock.

[IA64-SGI] sparse cleanups & misc fixes for sn2
This is a big patch mostly because I trimmed shub_mmr.h down from 17M to 11k
or so. It fixes a number of things sparse discovered and removes some dead
code, fixes up some prototypes, etc. Of note:
o sn_proc_fs.c was directly dereferencing user pointers, fixed
o sn_hwperf.c was missing an include and was using asm-ia64 directly
o the I/O routines were all missing proper sparse annotations
o dead code in prominfo_proc.c has been removed
o fix generic build by putting numionodes into asm/sn/io.h
With this patch applied, the check build is pretty clean. The sn_console bit
depends on some of the other changes, so it's included here.

[IA64] top level scheduler domain for ia64
Some have noticed that the overlapping sched domains code doesn't quite work
as intended (it results in disjoint domains on some machines), and that a top
level, machine spanning domain is needed. This patch from John Hawkes adds
it to the ia64 code. This allows processes to run on all CPUs in large
systems, though balancing is limited. It should go to Linus soon now
otherwise large systems will only have ~16p (depending on topology) usable by
the scheduler. I sanity checked it on a small system after rediffing John's
original, and he's done some testing on very large systems.
Nick, can you buy off on the sched.c change? Alternatively, do you want to
send that fix separately John? Nick did indeed ACK this change, but it isn't
dependent on this ia64 specific part ... so it's going to be submitted
separately.

[ARM] Add seqlocking to timers.
Sometimes, it's useful to have locking. Especially when we're
talking about time keeping.
It would appear that shemminger's patch of 5th February 2003
completely missed updating _ANY_ ARM timer implementations and,
because linux-arch didn't exist at the time, there appears to
have been no notification to any architecture developer that
maybe, just maybe, some work was required.
One wonders how many other changes are in the kernel which
architecture maintainers have missed.

[IA64] Avoid a rare deadlock during unwind
There is a rare deadlock condition during unwind script creation. If
build_script() is interrupted in the middle of creating the script, it
holds the script write lock. If the interrupt handler needs to call
unwind for some failure condition, unwind will try to read the
incomplete script and will deadlock on the script lock.
The fix is to disable interrupts while building the script, so
interrupt handlers never see partial scripts.
Promoting spin_lock_irqsave() from script_new() to find_save_locs()
changes the indentation, so the patch looks bigger than it really is.

The orphan list holds inodes that need to be truncated on recovery. In the
O_DIRECT case, it's used if we extend the inode --- the truncate on recovery
means we'll recover the newly-allocated disk blocks if we crash after the IO
starts but before i_size is updated on disk.
Now, the orphan list is *also* used to delete inodes that are unlinked but
still-open. Those get truncated but also deleted on recovery.
The orphan list is held both in memory and on disk. So the rules are that the
inode can't be reclaimed while on the orphan list. There are only two cases
--- either the inode is actively being written(O_DIRECT) or truncated (in
which case the inode is by definition not going to be reused), or it's
unlinked but still open (again, non-reclaimable).
But in the case where you're truncating or write(O_DIRECT)ing a file that is
*ALSO* unlinked, there's a problem --- the final unlink would put the inode on
the orphan list, but the write/truncate would try to add/remove it. End
result is that the inode disappears from the orphan list while it's still
unlinked-but-in-use.
That's just a leak-on-crash, it's not going to be detectable in normal use.
But it's still a bug, and the way we fix it is for direct-IO and truncate not
to do the ext3_orphan_del if the file is unlinked (ie. i_nlink==0).
