This prevents breaking fget_light if a single threaded application allows incoming file descriptors (in replies or on nodes). Should also prevent inserting a file in the wrong files_struct if the receving process execs in the middle of a transaction (between task_get_unused_fd_flags and task_fd_install). Signed-off-by:

Commit 46e0bb9c ("sched: Print sched_group::__cpu_power in sched_domain_debug") produces a messy dmesg output while attempting to print the sched_group::__cpu_power for each group in the sched_domain hierarchy. Fix this by avoid printing the __cpu_power for default cases. (i.e, __cpu_power == SCHED_LOAD_SCALE). [ Impact: reduce syslog clutter ] Reported-by:

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).

This reverts commit f520360d. 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.

The legacy old IDE ioctl API for this is a bit primitive so we try and map stuff sensibly onto it. - Set PIO over DMA devices to report 32bit - Add ability to change the PIO32 settings if the controller permits it - Add that functionality into the sff drivers - Add that functionality into the VLB legacy driver - Turn on the 32bit PIO on the ninja32 and add support there Signed-off-by:

When pata_legacy can't detect any device, it unregisters the platform_device and fails detection. However, it forgets to detach ata host triggering weird failures as the host later gets freed by devres while still attached. Fix it. Signed-off-by:

WDC WD1600JS-62MHB5 successfully hits the window between ATA/ATAPI-7 and Serial ATA II standards and reports 3c/c3 signature which now is assigned to SEMB. Make ata_dev_classify() report ATA_DEV_SEMB on the sig and let ata_dev_read_id() work around it by trying IDENTIFY once. This fixes bko#11579. Signed-off-by:

This patch correctly sets BAU memory mapped registers to point to the sending activation descriptor table and target payload table. The "Broadcast Assist Unit" is used for TLB shootdown in UV. The memory mapped registers that point to sending and receiving memory structures contain node numbers. In one case the __pa() function did not provide the node id of memory on blade zero in configurations where that id is nonzero. In another case, it was assumed that memory was allocated on the local node. That assumption is not true in a configuration in which the node has no memory. Tested on the UV hardware simulator.

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.

Prevent ixgbe from putting the adapter into D3 during shutdown except when we're going to power off the system, since doing that may generally cause problems with kexec to happen (such problems were observed for igb and forcedeth). For this purpose seperate ixgbe_shutdown() from ixgbe_suspend() and use the appropriate PCI PM callbacks in both of them. Signed-off-by:
