ext4 does not implement the fiemap operation correctly for extents
that are subject to delayed allocation. A fix is pending, but until
that has been well-tested let's disable it.

Subject: [PATCH] adfs: remove the big kernel lock
commit 4688a066ecf60086ea82f68edb3b036b567d2c08 upstream.
According to Russell King, adfs was written to not require the big
kernel lock, and all inode updates are done under adfs_dir_lock.
All other metadata in adfs is read-only and does not require locking.
The use of the BKL is the result of various pushdowns from the VFS
operations.

Subject: [PATCH] appletalk: remove the BKL
commit 60d9f461a20ba59219fdcdc30cbf8e3a4ad3f625 upstream.
This changes appletalk to use lock_sock instead of
lock_kernel for serialization. I tried to make sure
that we don't hold the socket lock during sleeping
functions, but I did not try to prove whether the
locks are necessary in the first place.
Compile-tested only.

Subject: [PATCH] drm/i810: remove the BKL
commit 1f692a14cbfbeb11f9a9c16f25c8ecb8ab50d3d5 upstream.
SMP i810 systems were practically nonexistent and the configuration
was not officially supported by Intel at the time when Pentium-III
was common.
With this change, it is still possible to build a distribution kernel
that has support for SMP and includes the i810 driver without the BKL.
As a precaution, check for the theoretical SMP case at run time and
refuse to load the driver.
We also need to disable CONFIG_PREEMPT builds for this driver.

Subject: [PATCH] staging/usbip: convert to kthread
commit 9720b4bc76a83807c68e00c62bfba575251bb73e upstream.
usbip has its own infrastructure for managing kernel
threads, similar to kthread. By changing it to use
the standard functions, we can simplify the code
and get rid of one of the last BKL users at the
same time.
Includes changes suggested by Max Vozeler.

Subject: [PATCH] ufs: remove the BKL
commit 788257d6101d986ac8f2741aaa35974af47f574c upstream.
This introduces a new per-superblock mutex in UFS to replace
the big kernel lock. I have been careful to avoid nested
calls to lock_ufs and to get the lock order right with
respect to other mutexes, in particular lock_super.
I did not make any attempt to prove that the big kernel
lock is not needed in a particular place in the code,
which is very possible.
The mutex has a significant performance impact, so it is only
used on SMP or PREEMPT configurations.
As Nick Piggin noticed, any allocation inside of the lock
may end up deadlocking when we get to ufs_getfrag_block
in the reclaim task, so we now use GFP_NOFS.

Subject: [PATCH] vt6656: Use request_firmware() to load firmware
commit 31d5bbf3da8c3c9de5944f2c09cbc7ea5a72bdb4 upstream.
The file added to linux-firmware is a copy of the current array which
does not have a recognisable header, so no validation is done.
Change the firmware version check to accept newer versions.
Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
[bwh: Restore firmware.c without the firmware blob]
