sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice()
moves data to a pipe, with the input being a user address range instead.
This uses an approach suggested by Linus, where we can hold partial ranges
inside the pages[] map. Hopefully this will be useful for network
receive support as well.

Providing more accurate coordinates for thumb press requires additional
steps in the filtering logic:
- Ignore samples found invalid by the debouncing logic, or the ones that
have out of bound pressure value.
- Add a parameter to repeat debouncing, so that more then two consecutive
good readings are required for a valid sample.

Move some inclusion of private header files and the definition of

Signed-off-by: David Woodhouse <dwmw2@infradead.org>
Currently, unifdef removes the comment which starts on the same line as

Move the comment onto a separate line.

It only really needs to define a few constants and include <asm/mman.h>
when it's used by userspace. Move the rest within #ifdef __KERNEL__

It was unconditionally including a whole bunch of headers which aren't
user-visible, and also exposing a lot of private internal stuff of its
own. Also fix some legacy character set to UTF-8 while we're at it.

It doesn't need to include i2c.h, because a forward declaration of
struct i2c_adapter is perfectly sufficient. And it can be inside
#ifdef __KERNEL__ along with the kernel-internal structure definition.

Some (?) non-x86 architectures require 8byte alignment for u_int64_t

There are some bugs in the current implementation of the SIOCSIWAP wext,
for example that when you do it twice and it fails, it may still try
another access point for some reason. This patch fixes this by introducing
a new flag that tells the association code that the bssid that is in use
was fixed by the user and shouldn't be deviated from.

machine_is() was always returning 0 when used in a module, because
we weren't exporting the machine definitions. This was why sound

The current PCI error recovery system keeps track of the number of PCI card
resets, and refuses to bring a card back up if this number is too large.
The goal of doing this was to avoid an infinite loop of resets if a card is
obviously dead. However, if the failures are rare, but the machine has a
high uptime, this mechanism might still be triggered; this is too harsh.
This patch will avoids this problem by decrementing the fail count after an
hour. Thus, as long as a pci card BSOD's less than 6 times an hour, it
will continue to be reset indefinitely. If it's failure rate is greater
than that, it will be taken off-line permanently.
This patch is larger than it might otherwise be because it changes
indentation by removing a pointless while-loop. The while loop is not
needed, as the handler is invoked once fo each event (by schedule_work());
the loop is leftover cruft from an earlier implementation.
