bf561-coreb: BKL unneeded for open()
...
According to Mike Frysinger:
http://permalink.gmane.org/gmane.linux.kernel/699279
open() does not need the BKL, so take it back out.

Call fasync() functions without the BKL
...
lock_kernel() calls have been pushed down into code which needs it, so
there is no need to take the BKL at this level anymore.
This work inspired and aided by Andi Kleen's unlocked_fasync() patches.

Chances are this is unneeded, but the code is twisty enough that it is hard
to tell.

Remove BKL from remote_llseek v2
...
- Replace remote_llseek with generic_file_llseek_unlocked (to force compilation
failures in all users)
- Change all users to either use generic_file_llseek_unlocked directly or
take the BKL around. I changed the file systems who don't use the BKL
for anything (CIFS, GFS) to call it directly. NCPFS and SMBFS and NFS
take the BKL, but explicitely in their own source now.
I moved them all over in a single patch to avoid unbisectable sections.
Open problem: 32bit kernels can corrupt fpos because its modification
is not atomic, but they can do that anyways because there's other paths who
modify it without BKL.
Do we need a special lock for the pos/f_version = 0 checks?
Trond says the NFS BKL is likely not needed, but keep it for now
until his full audit.
v2: Use generic_file_llseek_unlocked instead of remote_llseek_unlocked
and factor duplicated code (suggested by hch)

Make FAT users happier by not deadlocking
...
The FAT BKL removal patch can cause deadlocks. It turns out that the new
lock_super() calls are unneeded, remove them (as directed by Linus).
