* [PATCH] fix deadlock in drivers/pci/msi.cIngo Molnar2006-01-31
| | | | | | | | | | The lock validator caught another one: drivers/pci/msi.c is accessing &irq_desc[i].lock with interrupts enabled (!). The fix is to disable interrupts properly. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fix uidhash_lock <-> RCU deadlockIngo Molnar2006-01-31
| | | | | | | | | | | RCU task-struct freeing can call free_uid(), which is taking uidhash_lock - while other users of uidhash_lock are softirq-unsafe. The fix is to always take the uidhash_spinlock in a softirq-safe manner. Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: Paul E.

| * [BLOCK] elevator: allow default scheduler to potentially be modularNate Diller2006-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jens has decided that allowing the default scheduler to be a module is a bug, and should not be allowed under kconfig. However, I find that scenario useful for debugging, and wish for the kernel to be able to handle this situation without OOPSing, if I enable such an option in the .config directly. This patch dynamically checks for the presence of the compiled-in default, and falls back to no-op, emitting a suitable error message, when the default is not available Tested for a range of boot options on 2.6.16-rc1-mm2.

| * [BLOCK] elevator: default choice selectionNate Diller2006-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My previous default iosched patch did a poor job dealing with the 'elevator=' boot-time option. The old behavior falls back to the compiled-in default if the requested one is not registered at boot time. This patch dynamically evaluates which default to use, and emits a suitable error message when the requested scheduler is not available. It also does the 'as' -> 'anticipatory' conversion before elevator registration, which along with a modified registration function, allows it to correctly indicate which default scheduler is in use. Tested for a range of boot options on 2.6.16-rc1-mm2. Signed-off-by: Nate Diller <nate.diller@gmail.com> Signed-off-by: Jens Axboe <axboe@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ipw2100 driver misunderstood the parameter of txpower. Tx Power off means turn off the radio, but the driver interpret it as "can't set txpower". So when getting the txpower, it sets disabled=1 to the iwconifg tool in managed mode. And the tool will display "Tx Power off" when disabled=1. Now, in managed mode, iwconfig will not show "TX Power" if the radio is not switched off. It will only display "Tx Power off" only if the radio is killed. Signed-off-by: Hong Liu <hong.liu@intel.com> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.

[same as recent IPv4 IGMPv3 fix] 2) Remove 2 redundant "group_type" checks (can't be IPV6_ADDR_ANY within that loop, so checks are always true) 3) change an is_in() "return 0" to "return type == MLD2_MODE_IS_INCLUDE". It should always be "0" to get here, but it improves code locality to not assume it, and if some race allowed otherwise, doing the check would return the correct result.

That patch change these and the problem appear to be gone for me at least... I also fixed an mdelay -> msleep while I was at it to the pmac feature code that is called when toggling the PHY reset line since sungem doesn't call it in an atomic context anymore.
