locks: rename lease functions to reflect locks.c conventions

a filesystem-specific foo method if it exists, or falls back on a
generic method if it doesn't; thus vfs_foo is what is called when some
other part of the kernel (normally lockd or nfsd) wants to get a lock,
whereas foo is what filesystems call to use the underlying local
functionality as part of their lock implementation.

So rename setlease to vfs_setlease (which will call a
filesystem-specific setlease after a later patch) and __setlease to
setlease.

Also, vfs_setlease need only be GPL-exported as long as it's only needed
by lockd and nfsd.

UIO: Hilscher CIF card driver

this is a patch that adds support for Hilscher CIF DeviceNet and
Profibus cards. I tested it on a Kontron CPX board, and Thomas reviewed
it.

You can find the user space part here:

http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gz

Notes: cif_api.c is the main file you want to look at. It contains the
functions to open, close, mmap and so on. cif_dps.c adds functions
specific to Profibus cards, and cif_dn.c contains functions for
DeviceNet cards.  cif.c is a universal playground, it's just a small
test program.  The user space part of this UIO driver is still work in
progress, and not everything is tested yet. At the moment, the thread in
cif_api.c contains some code that artificially makes the card generate
interrupts, this was added for testing and will be removed later. But
the driver already contains all the functions needed for useful
operation, so it gives a good idea of how such a thing looks like.

For comparison, here's what you get from the manufacturer
(www.hilscher.com) when you ask for a Linux 2.6 driver:

debugfs: remove rmdir() non-empty complaint

Hi,

This patch kills the pointless debugfs rmdir() printk() when called on a
non-empty directory. blktrace will sometimes have to call it a few times
when forcefully ending a trace, which polutes the log with pointless
warnings.

Rationale:

- It's more code to work-around this "problem" in the debugfs users, and
  you would have to add code to check for empty directories to do so (or
  assume that debugfs is using simple_ helpers, but that would be a
  layering violation).

- Other rmdir() implementations don't complain about something this
  silly.

17 years ago[x86 setup] VGA: Clear the Protect bit before setting the vertical height
H. Peter Anvin [Tue, 17 Jul 2007 23:16:10 +0000 (16:16 -0700)]
[x86 setup] VGA: Clear the Protect bit before setting the vertical height

If the user has asked for the vertical height registers to be recomputed
by setting bit 15 in the video mode number, we do so without clearing the
Protect bit in the Vertical Retrace Register before setting the Overflow
register.  As a result, if the VGA BIOS had set the Protect bit, the
write to the Overflow register will be dropped, and bits [9:8] of the
vertical height will be left unchanged.

This is a bug imported from the assembly version of this code.  It was
pointed out by Etienne Lorrain.

[x86 setup] Fix assembly constraints

Fix incorrect assembly constraints.  In particular, fix memory
constraints used inside push..pop, which can cause invalid operation
since gcc may generate %esp-relative references.

Additionally:

outl() should have "dN" not "dn".

query_mca() shouldn't listen 16/32-bit registers in an 8-bit only
context.

has_eflag(): the "mask" is only used well after both the stack pointer
and the output registers have been touched; this requires the output
registers to be earlyclobbers (=&) and the input to exclude memory (so
"ri", not "g").

V4L/DVB (5820): Cleanup on cinergyT2: Remove unneeded if(1)

Before kernel 2.6.14, the driver checked for status before stopping the
thread. So, a compatibility test did exist. After 2.6.14, the
        if (state)
were replaced by:
        if (1)
However, it makes no sense to keep the if(1).

Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files. This change
also helps to make backports to properly work at the development tree.

Clean up the use of structure templates in cx88-i2c and cx88-vp3054-i2c.
For one thing, a real template is supposed to be read-only. And in some
cases it's more efficient to initialize the few fields we need
individually.

This clean-up shrinks cx88-i2c.o by 33% and cx88-vp3054-i2c.o by 49%
(x86_64).

V4L/DVB (5813): TUNER_TEA5761 kconfig fixes

The following doesn't make much sense:
drivers/media/video/Kconfig:
...
config TUNER_TEA5761
        tristate "TEA 5761 radio tuner (EXPERIMENTAL)"
...
drivers/media/video/Makefile:
...
ifneq ($(CONFIG_TUNER_TEA5761),)
  tuner-objs += tea5761.o
endif
...
With this setup, TUNER_TEA5761=m is equivalent to TUNER_TEA5761=y.
This patch therefore changes TUNER_TEA5761 to a bool.
The missing dependency on EXPERIMENTAL the prompt text indicates also
gets added by this patch.
Additionally, the Makefile entry can now be written in a more compact way.
