* mm: pass correct mm when growing stackHugh Dickins2009-04-161-1/+1
| | | | | | | | | | | | | | | | | Tetsuo Handa reports seeing the WARN_ON(current->mm == NULL) in security_vm_enough_memory(), when do_execve() is touching the target mm's stack, to set up its args and environment. Yes, a UMH_NO_WAIT or UMH_WAIT_PROC call_usermodehelper() spawns an mm-less kernel thread to do the exec. And in any case, that vm_enough_memory check when growing stack ought to be done on the target mm, not on the execer's mm (though apart from the warning, it only makes a slight tweak to OVERCOMMIT_NEVER behaviour).

* Revert "kobject: don't block for each kobject_uevent".Hugh Dickins2009-04-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f520360d93cdc37de5d972dac4bf3bdef6a7f6a7. Tetsuo Handa, running a kernel with CONFIG_DEBUG_PAGEALLOC=y and CONFIG_UEVENT_HELPER_PATH=/sbin/hotplug, has been hitting RCU detected CPU stalls: it's been spinning in the loop where do_execve() counts up the args (but why wasn't fixup_exception working? dunno). The recent change, switching kobject_uevent_env() from UMH_WAIT_EXEC to UMH_NO_WAIT, is broken: the exec uses args on the local stack here, and an env which is kfreed as soon as call_usermodehelper() returns. It very much needs to wait for the exec to be done. An alternative would be to keep the UMH_NO_WAIT, and complicate the code to allocate and free these resources correctly? but no, as GregKH pointed out when making the commit, CONFIG_UEVENT_HELPER_PATH="" is a much better optimization - though some distros are still saying /sbin/hotplug in their .config, yet with no such binary in their initrd or their root.

* Add block_write_full_page_endio for passing endio handlerChris Mason2009-04-162-11/+37
| | | | | | | | | | | | | | | | block_write_full_page doesn't allow the caller to control what happens when the IO is over. This adds a new call named block_write_full_page_endio so the buffer head end_io handler can be provided by the caller. This will be used by the ext3 data=guarded mode to do i_size updates in a workqueue based end_io handler. end_buffer_async_write is also exported so it can be called to do the dirty work of managing page writeback for the higher level end_io handler.

| * phylib: Add interrupt source check function to M88E1121R driverAnatolij Gustschin2009-04-131-0/+13
| | | | | | | | | | | | | | | | | | | | | | Add did_interrupt() function to check if a PHY port really caused an interrupt. This is needed in the case of shared PHY interrupt pin configuration to stop interrupt event processing for PHY ports which didn't cause an interrupt.

| * phylib: Allow early-out in phy_changeAnatolij Gustschin2009-04-132-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Marvell 88E1121R Dual PHY device can be hardware-configured to use shared interrupt pin for both PHY ports. For such PHY configurations using shared PHY interrupt phy_interrupt() handler will also schedule a work for PHY port which didn't cause an interrupt. This patch adds a possibility for PHY drivers to provide did_interrupt() function which reports if the PHY (or a PHY port in a multi-PHY device) generated an interrupt. This function is called in phy_change() as phy_change() shouldn't proceed if it is invoked for a PHY which didn't cause an interrupt. So check for interrupt originator in phy_change() to allow early-out. Signed-off-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: David S. Miller <davem@davemloft.net>

You have to use the original setting mechanism to be correct on all architectures. The attached patch fixes parisc.

| * | Bonding: fix zero address hole bug in arp_ip_target listBrian Haley2009-04-133-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a zero address hole bug in the bonding arp_ip_target list that was causing the bond to ignore ARP replies (bugz 13006). Instead of just setting the array entry to zero, we now copy any additional entries down one slot, putting the zero entry at the end. With this change we can now have all the loops that walk the array stop when they hit a zero since there will be no addresses after it.
