Staging: udlfb: explicit dependencies and warnings
Specify Kconfig dependencies, and include warnings for building as a module
udlfb is dependent on FB_DEFERRED_IO, FB_SYS_*, and FB_MODE_HELPERS
Because many kernels do not include defio (which cannot be built
as a module), yet users want to be able to build udlfb as a module later,
udlfb has ifdefs and these dependency warnings to help udlfb build with or
without certain dependencies, but also print warnings for any lost function.
Even though this kind of flexibility isn't common, we've gotten feedback
from a significant portion of users that they were frustrated without it.

Staging: udlfb: Support for fbdev mmap clients (defio)
Add support for fbdev mmap clients who don't send damage ioctls
Because DisplayLink devices are out on the other end of usb, their
"framebuffer" is just normal system memory. So memory mapped writes
don't automatically trigger anything. So up to this point, standard
fbdev clients who rely on mmap() will get an unchanging screen.
This patch makes udlfb a client of Jaya Kumar's defio framework - which sets
up page fault triggers, and those faults are accumulated and sent to udlfb
on a defferred basis, to process as damage notifications for the framebuffer.
Because this involves more overhead than a notification directly from
the application (e.g. just passing on X DAMAGE extension notifications),
a sysfs attribute is provided by udlfb to control defio support.
/sys/class/graphics/fb*/use_defio - writing a "0" to this file before
calling mmap() causes defio to not be initialized - instead udlfb
will rely on getting damage notifications directly through the damage ioctl.
There are unsolved rendering problems with defio (horizontal dead regions
on framebuffer, that accumulate over time) which still needs a fix.

pages. So, remove redundant logic for the same in ramzswap_write().

Staging: ramzswap: Return proper error code on device create failure
Currently, we return 0 if create_device() fails and 1 otherwise.
Now, proper error code is returned from create_device() and the
same is propagated as module error code from ramzswap_init().
Also added some cleanups for ramzswap_init(), improving function
structure.

ramzswap block size needs to be set equal to PAGE_SIZE to
avoid receiving any unaligned block I/O requests (happens
due to readahead logic during swapon). These unaligned

Staging: ramzswap: Use lock for 64-bit stats
64-bit stats corruption was observed when ramzswap was
used on SMP systems. To prevent this, use separate spinlock
to protect these stats.
Also, replace stat_*() with rzs_stat*() to avoid possible
conflict with core kernel code.
Eventually, these will be converted to per-cpu counters
if this driver finds use on large scale systems and this
locking is found to affect scalability.
