The original zcache in staging was a "demo" version, and this new zcache
is a significant rewrite. While certain disagreements were being resolved,
both "old zcache" and "new zcache" needed to reside in the staging tree
simultaneously. In order to minimize code change and churn, the newer
version of zcache was temporarily merged into the "ramster" staging driver
which, prior to that, had at one time heavily leveraged the older version
of zcache. So, recently, "new zcache" resided in the ramster directory.
Got that? No? Sorry, temporary political compromises are rarely pretty.
The older version of zcache is no longer being maintained and has now
been removed from the staging tree. So now the newer version of zcache
can rightfully reclaim sole possession of the name "zcache".

staging: comedi: introduce addi_watchdog driver
Many of the ADDI-DATA drivers have a "watchdog" subdevice that can
be used to monitor digital output activity. All the digital outputs
are released (set to 0) if the digital outputs are not accessed, or
the watchdog it not pinged, before the timeout of the watchdog
occurs. The only difference in the drivers for the watchdog subdevice
is the base address used to talk to the watchdog registers.
Instead of duplicating the code needed to support this watchdog,
introduce a helper module, similar to the 8255 module. This module
will be select'ed by the drivers that can use it.

staging: comedi: comedi_buf: factor out common comedi_buf_write_alloc_* code
The only difference between comedi_buf_write_alloc() and the *_strict()
version is that the *_strict() one will only allocate the chunk if it
can completely fulfill the request.
Factor out the common code and add a flag parameter to indicate the 'strict'
usage. Change the exported functions so they are just wrappers around the
common function.
Cleanup the common function a bit and use the comedi_buf_write_n_available()
helper to determine the number of bytes available.
comedi_buf_write_n_available() is not used outside this module so make it
static. Since the only caller is __comedi_buf_write_alloc(), which will
always have a valid async pointer and already has a memory barrier, we
can remove the unnecessary (async == NULL) test as well as the smp_mb().
Also, the rounding of the sample size can be removed since the caller
does not need it.

staging: comedi: comedi_buf: factor out new buffer allocation code
The function comedi_buf_alloc() first frees any allocated buffer then,
optionally, allocates a new buffer.
Factor out the new buffer allocation code to a new function. This
allows reducing the indent level and makes the code a bit cleaner.
Also, cleanup to factored out code to make it a bit more concise.
Use a local variable for the current comedi_buf_page being allocated.
This cleans up the ugly line breaks used to keep the lines < 80 chars.
Move the #ifdef'ery for the page protection determination out of the
vmap() call.
