2008-04-30SGI Altix mmtimer: allow larger number of timers per nodeDimitri Sivanich
The purpose of this patch to the SGI Altix specific mmtimer (posix timer) driver is to allow a virtually infinite number of timers to be set per node. Timers will now be kept on a sorted per-node list and a single node-based hardware comparator is used to trigger the next timer.

2008-04-30tty_ioctl: soft carrier handlingAlan Cox
First cut at moving the soft carrier handling knowledge entirely into the core code. One or two drivers still needed to snoop these functions to track CLOCAL internally. Instead make TIOCSSOFTCAR generate the same driver calls as other termios ioctls changing the clocal flag. This allows us to remove any driver knowledge and special casing. Also while we are at it we can fix the error handling.

2008-04-30Resume TTY on SUSP and fix CRNL order in N_TTY line disciplineJoe Peterson
Refine these behaviors in the N_TTY line discipline: 1) Handle the signal characters consistently when received in a stopped TTY so that SUSP (typically ctrl-Z) behaves like INTR and QUIT in resuming a stopped TTY. 2) Adjust the order in which the IGNCR/ICRNL/INLCR processing is applied to be more logical and consistent with the behavior of other Unix systems.

2008-04-30redo locking of tty->pgrpAlan Cox
Historically tty->pgrp and friends were pid_t and the code "knew" they were safe. The change to pid structs opened up a few races and the removal of the BKL in places made them quite hittable.

2008-04-30vt_ioctl: Prepare for BKL push downAlan Cox
This one could do with some eyeballs on it. In theory it simply wraps the ioctl handler in lock/unlock_kernel ready for the lock/unlocks to be pushed into specific switch values. To do that means changing the code to return via a common exit path not all over the place as it does now, hence the big diff Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
