taskstats: use real microsecond granularity for CPU times

2010-10-28T01:03:17Z

The taskstats interface uses microsecond granularity for the user and system time values. The conversion from cputime to the taskstats values uses the cputime_to_msecs primitive which effectively limits the granularity to milliseconds. Add the cputime_to_usecs primitive for architectures that have better, more precise CPU time values. Remove cputime_to_msecs primitive because there are no more users left.

mm: remove pte_*map_nested()

2010-10-26T23:52:08Z

Since we no longer need to provide KM_type, the whole pte_*map_nested() API is now redundant, remove it.

ioctl: Use asm-generic/ioctls.h on ia64 (enables termiox)

2010-10-22T17:20:00Z

This patch converts ia64 to use asm-generic/ioctls.h instead of its own version. The differences between the arch-specific version and the generic version are as follows: - The generic version adds TIOCSRS485 and TIOCGRS485, which are unused by any driver available on this architecture. - The generic version adds support for termiox Cc: Tony Luck Cc: Fenghua Yu Signed-off-by: Jeff Mahoney Signed-off-by: Greg Kroah-Hartman
