There are several missing things at the driver, preventing, for example,
the code to start/stop DMA to actually work. Fix them before implementing
a routine to store data at the audio buffers.

This is a new driver for the Windows Media Center Edition/eHome
Infrared Remote transceiver devices. Its a port of the current
lirc_mceusb driver to ir-core, and currently lacks transmit support,
but will grow it back soon enough... This driver also differs from
lirc_mceusb in that it borrows heavily from a simplified IR buffer
decode routine found in Jon Smirl's earlier ir-mceusb port.
This driver has been tested on the original first-generation MCE IR
device with the MS vendor ID, as well as a current-generation device
with a Topseed vendor ID. Every receiver supported by lirc_mceusb
should work equally well. Testing was done primarily with RC6 MCE
remotes, but also briefly with a Hauppauge RC5 remote, and all works
as expected.
v2: fix call to ir_raw_event_handle so repeats work as they should.

This is the RC6 keymap for the Windows Media Center Edition remotes
that come bundled with MCE/eHome Infrared Remote transceivers. Tested
with 3 different variants of the remote, but its possible there are
still some additional keys missing, but its simple enough to add them
in later...
This patch also adds an IR_TYPE_ALL convenience macro to make life
easier for receivers that support all IR protocols.

Rather than registering all IR protocol decoders as enabled when bringing
up a new device, only enable the IR protocol decoder that matches the
keymap being loaded. Additional decoders can be enabled on the fly by
those that need to, either by twiddling sysfs bits or by using the
ir-keytable util from v4l-utils.
Functional testing done with the mceusb driver, and it behaves as expected,
only the rc6 decoder is enabled, keys are all handled properly, etc.

Self-NAK. The only place we actually *care* about the retval from a
RUN_DECODER() call is in __ir_input_register(), and currently, its
looking for retval < 0, which is currently never possible. When we're
running the decoders, either they fail and return -EINVAL or they
succeed and return 0, and in the register case, we get either a
negative error (ex: -ENOMEM from rc6) or 0, so with the above, _sumrc
will *always* be 0 in the two cases I'm looking at. The third place
where RUN_DECODER gets called (decoder unregister) doesn't care about
the retval either. New patch below, including updated comments about
the macro.

other choice
The tuple got from unique_tuple() doesn't need to be really unique, so the
check for the unique tuple isn't necessary, when there isn't any other
choice. Eliminating the unnecessary nf_nat_used_tuple() can save some CPU
cycles too.

Right now, there's no clear separation between the uid that owns the
credentials used to do the mount and the overriding owner of the files
on that mount.
Add a separate cred_uid field that is set to the real uid
of the mount user. Unlike the linux_uid, the uid= option does not
override this parameter. The parm is sent to cifs.upcall, which can then
preferentially use the creduid= parm instead of the uid= parm for
finding credentials.
This is not the only way to solve this. We could try to do all of this
in kernel instead by having a module parameter that affects what gets
passed in the uid= field of the upcall. That said, we have a lot more
flexibility to change things in userspace so I think it probably makes
sense to do it this way.

Add a mount option 'fsc' to enable local caching on CIFS.
I considered adding a separate debug bit for caching, but it appears that
debugging would be relatively easier with the normal CIFS_INFO level.
As the cifs-utils (userspace) changes are not done yet, this patch enables
'fsc' by default to enable testing.

Define inode-level data storage objects (managed by cifsInodeInfo structs).
Each inode-level object is created in a super-block level object and is itself
a data storage object in to which pages from the inode are stored.
The inode object is keyed by UniqueId. The coherency data being used is
LastWriteTime, LastChangeTime and end of file reported by the server.
