With all the patches we have queued in the BKL removal tree, only a
few dozen modules are left that actually rely on the BKL, and even
there are lots of low-hanging fruit. We need to decide what to do
about them, this patch illustrates one of the options:
Every user of the BKL is marked as 'depends on BKL' in Kconfig,
and the CONFIG_BKL becomes a user-visible option. If it gets
disabled, no BKL using module can be built any more and the BKL
code itself is compiled out.
The one exception is file locking, which is practically always
enabled and does a 'select BKL' instead. This effectively forces
CONFIG_BKL to be enabled until we have solved the fs/lockd
mess and can apply the patch that removes the BKL from fs/locks.c.

The go7007 driver has a potential buffer overflow and pointer corruption
bug which causes a crash while capturing MJPEG. The motion detection
(MODET) active_map array can be overflowed by JPEG frame data that
emulates a MODET start code. The active_map overflow overwrites the
active_buf pointer, causing a crash.
The JPEG data that emulated MODET start code was being removed from the
output, resulting in garbled JPEG frames. Therefore ignore MODET start
codes when MODET is not enabled.

The driver author seems to not worked on this driver since its conversion
from 2.2 to 2.4. Nobody is known to have a stradis hardware for testing. As
it still uses V4L1 API, BKL and probably some other old stuff, someone would
need to work on it to preserve the driver. Instead of investing time and
efforts to keep porting it to work with new API's, it seems better to just
drop the driver.
So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

functionality that were not migrated is the support for parallel port,
as:
1) the developer didn't find any hardware;
2) it doesn't seem important to keep support for a parallel port webcam,
as this is an obsolete technology;
3) the changes at gspca for it to work with parallel port would be very large;
4) this driver still uses BKL.

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

-Remove scan_attrs from chip info structure.
-Remove name from chip info structure, use new spi_device_id instead.
-Allow transfer buffers to live in their own cache lines, to avoid DMA/cache coherency issues.
-Move scan el code into the ring buffer file.
-Use helper function to alloc the pollfunc.
-Use regulator framework and get vref_mv from the regulator in case not specified by pdata.
-Devices with buit-in reference use vref from the chip info structure
-Don't error on missing platform_data
-Make vref_mv type unsigned short
-Print in_scale "Vref / 2^(bits)" if fractional.

In the original code the interface name was IFNAMSIZ + 1, but that
caused problems in dhd_ifname2idx() which does:
strncmp(dhd->iflist[i]->name, name, IFNAMSIZ)
The wl_event_msg_t struct can only store 16 character names as well.
And thirdly there is a potential buffer overflow in dhd_op_if() because
if->net->name is IFNAMSIZ and we do:
