If a transaction that contains a file descriptor fails on a later object, the new file descriptor needs to be closed. If this is a binder file descriptor we would deadlock in flush. If there were no other references to the file at this point release would also be called. Signed-off-by:

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:
