V4L/DVB (8108): Fix open/close race in saa7134

The saa7134 driver uses a (non-atomic) variable in an attempt to
only allow one opener of the device (how it deals with sending
the fd over unix sockets I don't know).

Unfortunately, the release function first decrements this variable,
and THEN goes on to disable more of the device. This allows for
a race where another opener of the device comes in after the decrement of
the variable, configures the hardware just to then see the hardware
be disabled by the rest of the release function.

This patch makes the release function use the same lock as the open
function to protect the hardware as well as the variable (which now
at least has some locking to protect it).

used by both xen and kvm (pvclock-abi.h).

It also adds some helper functions to read system time and
wall clock time from a paravirtual clocksource (pvclock.[ch]).
They are based on the xen code.  They are enabled using

Subsequent patches of this series will put the code in use.

[GFS2] fix gfs2 block allocation (cleaned up)

This patch fixes bz 450641.

This patch changes the computation for zero_metapath_length(), which it
renames to metapath_branch_start(). When you are extending the metadata
tree, The indirect blocks that point to the new data block must either
diverge from the existing tree either at the inode, or at the first
indirect block. They can diverge at the first indirect block because the
inode has room for 483 pointers while the indirect blocks have room for
509 pointers, so when the tree is grown, there is some free space in the
first indirect block. What metapath_branch_start() now computes is the
height where the first indirect block for the new data block is located.
It can either be 1 (if the indirect block diverges from the inode) or 2
(if it diverges from the first indirect block).
