This is a workaround for the case edge-triggered irq's. Several users
seem to have broken configurations sharing edge-triggered irq's. To avoid
losing IRQ's, reshedule if more work arrives.
The changes to netdevice.h are to extract the part that puts device
back in list into separate inline.

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.

BKL does not protect against races if the task may sleep between
checking and setting a value. So move checking of file->private_data
near to setting it in fuse_fill_super().

A deadlock was possible, when the last reference to the superblock was
held due to a background request containing a file reference.
Releasing the file would release the vfsmount which in turn would
release the superblock. Since sbput_sem is held during the fput() and
fuse_put_super() tries to acquire this same semaphore, a deadlock
results.
The solution is to move the fput() outside the region protected by
sbput_sem.

This reverts 73ce8355c2 commit.
It was wrong, because it didn't take into account the requirement,
that iput() for background requests must be performed synchronously
with ->put_super(), otherwise active inodes may remain after unmount.
The right solution is to keep the sbput_sem and perform iput() within
the locked region, but move fput() outside sbput_sem.

Make the move_from_pipe() actors return number of bytes processed, then
move_from_pipe() can decide more cleverly when to move on to the next

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.

Patch from Richard Purdie
The AAPCS says that enums can be variably sized depending on the range
of valid values. This is not the accepted behaviour under linux so for
compatibility gcc has an aapcs-linux target, the main difference being
that enums are always of type int. Change the ARM Makefile to use this
target.

If nf_ct_l3proto_find_get() fails to get the refcount of
nf_ct_l3proto_generic, nf_ct_l3proto_put() will drop the refcount
too far.
This gets rid of '.me = THIS_MODULE' of nf_ct_l3proto_generic so that
nf_ct_l3proto_find_get() doesn't try to get refcount of it.
It's OK because its symbol is usable until nf_conntrack.ko is unloaded.
This also kills unnecessary NULL pointer check as well.
__nf_ct_proto_find() allways returns non-NULL pointer.

The MMC layer gives us two parts for the timeout calculation - a fixed
timeout in nanoseconds, and a card clock-speed dependent part.
The PXA MMC hardware allows for a timeout based on the fixed host clock
speed only. This resulted in some cards being given a short timeout,
and therefore failing to work.
