* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6: [PATCH] Driver core: Fix prefix driver links in /sys/module by bus-name
Fix sched profiling typo, introduced by the sleep profiling patch. This bug caused profile=sched to not work. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
In the kernels later than 2.6.19 there is a regression that makes swsusp fail if the resume device is not explicitly specified. It can be fixed by adding an additional parameter to mm/swapfile.c:swap_type_of() allowing us to pass the (struct block_device *) corresponding to the first available swap back to the caller.

The parsing of some kernel parameters seem to enable irq's at a stage that irq's are not supposed to be enabled (Particularly the ide kernel parameters). Having irq's enabled before the irq controller is initialized might lead to a kernel panic. This patch only detects this behaviour and warns about wich parameter caused it.

Modules may have drivers with the same name on different buses. This patch fixes this problem. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
Commit b2b2cbc4b2a2f389442549399a993a8306420baf introduced a user- visible change: ->pdeath_signal is sent only when the entire thread group exits. While this change is imho good, it may break things. So restore the old behaviour for now. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> To: Albert Cahalan <acahalan@gmail.com> Cc: Eric W.

Remove the __resched_legal() check: it is conceptually broken. The biggest problem it had is that it can mask buggy cond_resched() calls. A cond_resched() call is only legal if we are not in an atomic context, with two narrow exceptions: - if the system is booting - a reacquire_kernel_lock() down() done while PREEMPT_ACTIVE is set But __resched_legal() hid this and just silently returned whenever these primitives were called from invalid contexts. (Same goes for cond_resched_locked() and cond_resched_softirq()). Furthermore, the __legal_resched(0) call was buggy in that it caused unnecessarily long softirq latencies via cond_resched_softirq(). (which is only called from softirq-off sections, hence the code did nothing.) The fix is to resurrect the efficiency of the might_sleep checks and to only allow the narrow exceptions.
