2007-02-11[PATCH] Char: isicom, remove tty_{hang,wake}up bottomhalvesJiri Slaby
- tty_hangup() itself schedules work, so there is no need to schedule hangup in the driver - tty_wakeup(): it's safe to call it while in atomic, so that its schedule_work might be also wiped out Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-11[PATCH] vt: refactor console SAK processingEric W. Biederman
This does several things. - It moves looking up of the current foreground console into process context where we can safely take the semaphore that protects this operation. - It uses the new flavor of work queue processing. - This generates a factor of do_SAK, __do_SAK that runs immediately. - This calls __do_SAK with the console semaphore held ensuring nothing else happens to the console while we process the SAK operation. - With the console SAK processing moved into process context this patch removes the xchg operations that I used to attempt to attomically update struct pid, because of the strange locking used in the SAK processing. With SAK using the normal console semaphore nothing special is needed. Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Eric W.

Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the Help message. It was previously done via X, but X is already used for Xmon on ppc & powerpc platforms and this collision needs to be avoided. All callers of register_sysrq_key() are now marked in the sysrq op/key table. I didn't mark 'h' as Help because Help is just printed for any unknown key, such as '?'.

As per Hugh Dickins: "Nadia Derbey has reported that mmap of /dev/kmem no longer works with the kernel virtual address as offset, and Franck has confirmed that his patch came from a misunderstanding of what an offset means to /dev/kmem - whereas his patch description seems to say that he was correcting the offset on a few plaforms, there was no such problem to correct, and his patch was in fact changing its API on all platforms."

2006-12-22[AGPGART] fix detection of aperture size versus GTT size on G965Eric Anholt
On the G965, the GTT size may be larger than is required to cover the aperture. (In fact, on all hardware we've seen, the GTT is 512KB to the aperture's 256MB). A previous commit forced the aperture size to 512MB on G965 to match GTT, which would likely result in hangs at best if users tried to rely on agpgart's aperture size information. Instead, we use the resource length for the aperture size and the system's reported GTT size when available for the GTT size. Because the MSAC registers which had been read for aperture size detection on i9xx chips just cause a change in the resource size, we can use generic code for aperture detection on all i9xx.

2006-12-22[AGPGART] Remove unnecessary flushes when inserting and removing pages.Thomas Hellstrom
This patch is to speed up flipping of pages in and out of the AGP aperture as needed by the new drm memory manager. A number of global cache flushes are removed as well as some PCI posting flushes. The following guidelines have been used: 1) Memory that is only mapped uncached and that has been subject to a global cache flush after the mapping was changed to uncached does not need any more cache flushes. Neither before binding to the aperture nor after unbinding. 2) Only do one PCI posting flush after a sequence of writes modifying page entries in the GATT.
