Merge tag 'staging-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver tree merge from Greg Kroah-Hartman: "Here's the big staging tree merge for 3.8-rc1 There's a lot of patches in here, the majority being the comedi rework/cleanup that has been ongoing and is causing a huge reduction in overall code size, which is amazing to watch. We also removed some older drivers (telephony and rts_pstor), and added a new one (fwserial which also came in through the tty tree due to tty api changes, take that one if you get merge conflicts.) The iio and ipack drivers are moving out of the staging area into their own part of the kernel as they have been cleaned up sufficiently and are working well. Overall, again a reduction of code: 768 files changed, 31887 insertions(+), 82166 deletions(-) All of this has been in the linux-next tree for a while.

- DESCRIPTION
- Returns the current system time in a low and a high part. The low part
- is expressed in microseconds. The high part is incremented when the low
- part wraps to provide an extended range.
+ Although the time is expressed in microseconds the actual resolution is
+ platform dependent and can be less. It is recommended that the
+ resolution is at least 10 milliseconds.
- The caller may provide a NULL pointer as the high parameter. In this case
- the function just returns the low part and ignores the high parameter.
+PARAMETERS
+ high - Pointer to variable that will receive the high part of the
+ current system time. Passing NULL is valid.
- Although the time is expressed in microseconds the actual resolution is
- platform dependent and can be less. It is recommended that the
- resolution is at least 10 milliseconds.

- PARAMETERS
- high - Pointer to variable that will receive the high part of the

-
- RETURNS
- Low part of current system time in microseconds.

+ Low part of current system time in microseconds.
