sched/wait: Fix the signal handling fix

2015-12-13T22:30:59Z

Jan Stancek reported that I wrecked things for him by fixing things for Vladimir :/ His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which should not be possible, however my previous patch made this possible by unconditionally checking signal_pending(). We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.

kernel: remove stop_machine() Kconfig dependency

2015-12-12T18:15:34Z

Currently the full stop_machine() routine is only enabled on SMP if module unloading is enabled, or if the CPUs are hotpluggable. This leads to configurations where stop_machine() is broken as it will then only run the callback on the local CPU with irqs disabled, and not stop the other CPUs or run the callback on them. For example, this breaks MTRR setup on x86 in certain configs since ea8596bb2d8d379 ("kprobes/x86: Remove unused text_poke_smp() and text_poke_smp_batch() functions") as the MTRR is only established on the boot CPU. This patch removes the Kconfig option for STOP_MACHINE and uses the SMP and HOTPLUG_CPU config options to compile the correct stop_machine() for the architecture, removing the false dependency on MODULE_UNLOAD in the process.

mm: kmemleak: mark kmemleak_init prototype as __init

2015-12-12T18:15:34Z

The kmemleak_init() definition in mm/kmemleak.c is marked __init but its prototype in include/linux/kmemleak.h is marked __ref since commit a6186d89c913 ("kmemleak: Mark the early log buffer as __initdata"). This causes a section mismatch which is reported as a warning when building with clang -Wsection, because kmemleak_init() is declared in section .ref.text but defined in .init.text. Fix this by marking kmemleak_init() prototype __init. Signed-off-by: Nicolas Iooss Signed-off-by: Catalin Marinas Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

USB: add quirk for devices with broken LPM

2015-12-11T23:40:51Z

Some USB device / host controller combinations seem to have problems with Link Power Management. For example, Steinar found that his xHCI controller wouldn't handle bandwidth calculations correctly for two video cards simultaneously when LPM was enabled, even though the bus had plenty of bandwidth available. This patch introduces a new quirk flag for devices that should remain disabled for LPM, and creates quirk entries for Steinar's devices. Signed-off-by: Alan Stern Reported-by: Steinar H.
