2015-05-09ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for exynos5250-snowJavier Martinez Canillas
The Marvell mwifiex driver prevents the system to enter into a suspend state if the card power is not preserved during a suspend/resume cycle. So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow. Add the keep-power-in-suspend Power Management property to the SDIO/MMC node so the mwifiex suspend handler doesn't fail and the system is able to enter into a suspend state.

2015-05-09ARM: dts: Make DP a consumer of DISP1 power domain on Exynos5420Javier Martinez Canillas
Commit ea08de16eb1b ("ARM: dts: Add DISP1 power domain for exynos5420") added a device node for the Exynos5420 DISP1 power domain but dit not make the DP controller a consumer of that power domain. This causes an "Unhandled fault: imprecise external abort" error if the exynos-dp driver tries to access the DP controller registers and the PD was turned off. This lead to a kernel panic and a complete system hang. Make the DP controller device node a consumer of the DISP1 power domain to ensure that the PD is turned on when the exynos-dp driver is probed.

2015-05-08iio: adc: cc10001: Fix the channel number mappingNaidu Tellapati
When some of the ADC channels are reserved for remote CPUs, the scan index and the corresponding channel number doesn't match. This leads to convesion on the incorrect channel during triggered capture. Fix this by using a scan index to channel mapping encoded in the iio_chan_spec for this purpose while starting conversion on a particular ADC channel in trigger handler. Also, the channel_map is not really used anywhere but in probe(), so no need to keep track of it. Remove it from device structure. While here, add 1 to number of channels to register timestamp channel with the IIO core.

2015-05-08serial: omap: Fix error handling in probeSemen Protsenko
There is pm_qos_add_request() being executed on serial_omap_probe(), which stores "&up->pm_qos_request" from omap-serial driver to "pm_qos_array[PM_QOS_CPU_DMA_LATENCY]->constraints". If serial_omap_probe() fails after pm_qos_add_request() (e.g. on uart_add_one_port() call), pm_qos_array still keeping pm_qos_request struct from omap-serial driver, which is not valid anymore (since driver failed). This leads further to kernel crash on pm_qos_update_target(), executing from some completely different driver. We were observing this while trying to run audio playback while having one of omap-serial driver instances failed on uart_add_one_port() call: Unable to handle kernel paging request at virtual address fffffffc Backtrace: (plist_add) from (pm_qos_update_target) (pm_qos_update_target) from (pm_qos_add_request) (pm_qos_add_request) from (snd_pcm_hw_params) (snd_pcm_hw_params) from (snd_pcm_common_ioctl1) (snd_pcm_common_ioctl1) from (snd_pcm_playback_ioctl1) (snd_pcm_playback_ioctl1) from (snd_pcm_playback_ioctl) (snd_pcm_playback_ioctl) from (do_vfs_ioctl) (do_vfs_ioctl) from (SyS_ioctl) (SyS_ioctl) from (ret_fast_syscall) This patch adds pm_qos_remove_request() on fail path in serial_omap_probe() in order to fix this issue.

2015-05-08drm/tegra: Don't use vblank_disable_immediate on incapable driver.Mario Kleiner
Tegra would not only need a hardware vblank counter that increments at leading edge of vblank, but also support for instantaneous high precision vblank timestamp queries, ie. a proper implementation of dev->driver->get_vblank_timestamp(). Without these, there can be off-by-one errors during vblank disable/enable if the scanout is inside vblank at en/disable time, and additionally clients will never see any useable vblank timestamps when querying via drmWaitVblank ioctl. This would negatively affect swap scheduling under X11 and Wayland.

2015-05-08perf/x86/intel: Fix SLM cache event listKan Liang
iTLB-load-misses and LLC-load-misses count incorrectly on SLM. There is no ITLB.MISSES support on SLM. Event PAGE_WALKS.I_SIDE_WALK should be used to count iTLB-load-misses. This event counts when an instruction (I) page walk is completed or started. Since a page walk implies a TLB miss, the number of TLB misses can be counted by counting the number of pagewalks. DMND_DATA_RD counts both demand and DCU prefetch data reads. However, LLC-load-misses should only count demand reads. There is no way to not include prefetches with a single counter on SLM. So the LLC-load-misses support should be removed on SLM.

2015-05-08sched/core: Fix regression in cpuset_cpu_inactive() for suspendOmar Sandoval
Commit 3c18d447b3b3 ("sched/core: Check for available DL bandwidth in cpuset_cpu_inactive()"), a SCHED_DEADLINE bugfix, had a logic error that caused a regression in setting a CPU inactive during suspend. I ran into this when a program was failing pthread_setaffinity_np() with EINVAL after a suspend+wake up. A simple reproducer: $ ./a.out sched_setaffinity: Success $ systemctl suspend $ ./a.out sched_setaffinity: Invalid argument ... where ./a.out is: #define _GNU_SOURCE #include <errno.h> #include <sched.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> int main(void) { long num_cores; cpu_set_t cpu_set; int ret; num_cores = sysconf(_SC_NPROCESSORS_ONLN); CPU_ZERO(&cpu_set); CPU_SET(num_cores - 1, &cpu_set); errno = 0; ret = sched_setaffinity(getpid(), sizeof(cpu_set), &cpu_set); perror("sched_setaffinity"); return ret ? EXIT_FAILURE : EXIT_SUCCESS; } The mistake is that suspend is handled in the action == CPU_DOWN_PREPARE_FROZEN case of the switch statement in cpuset_cpu_inactive(). However, the commit in question masked out CPU_TASKS_FROZEN from the action, making this case dead. The fix is straightforward.

2015-05-08sched: Handle priority boosted tasks proper in setscheduler()Thomas Gleixner

2015-05-08md/raid5: fix handling of degraded stripes in batches.NeilBrown
There is no need for special handling of stripe-batches when the array is degraded. There may be if there is a failure in the batch, but STRIPE_DEGRADED does not imply an error. So don't set STRIPE_BATCH_ERR in ops_run_io just because the array is degraded. This actually causes a bug: the STRIPE_DEGRADED flag gets cleared in check_break_stripe_batch_list() and so the bitmap bit gets cleared when it shouldn't. So in check_break_stripe_batch_list(), split the batch up completely - again STRIPE_DEGRADED isn't meaningful. Also don't set STRIPE_BATCH_ERR when there is a write error to a replacement device. This simply removes the replacement device and requires no extra handling. Signed-off-by: NeilBrown <neilb@suse.de>
2015-05-08md/raid5: fix allocation of 'scribble' array.NeilBrown
As the new 'scribble' array is sized based on chunk size, we need to make sure the size matches the largest of 'old' and 'new' chunk sizes when the array is undergoing reshape. We also potentially need to resize it even when not resizing the stripe cache, as chunk size can change without changing number of devices. So move the 'resize' code into a separate function, and consider old and new sizes when allocating.

2015-05-07ACPI / init: Fix the ordering of acpi_reserve_resources()Rafael J. Wysocki
Since acpi_reserve_resources() is defined as a device_initcall(), there's no guarantee that it will be executed in the right order with respect to the rest of the ACPI initialization code. On some systems this leads to breakage if, for example, the address range that should be reserved for the ACPI fixed registers is given to the PCI host bridge instead if the race is won by the wrong code path. Fix this by turning acpi_reserve_resources() into a void function and calling it directly from within the ACPI initialization sequence.

2015-05-07drivers: CCI: fix used_mask init in validate_group()Mark Salter
Currently in validate_group(), there is a static initializer for fake_pmu.used_mask which is based on CPU_BITS_NONE but the used_mask array size is based on CCI_PMU_MAX_HW_EVENTS. CCI_PMU_MAX_HW_EVENTS is not based on NR_CPUS, so CPU_BITS_NONE is not correct and will cause a build failure if NR_CPUS is set high enough to make CPU_BITS_NONE larger than used_mask.
