2015-01-07pinctrl: st: Add irq_disable hook to st_gpio_irqchipPatrice CHOTARD
Currently disable_irq() doesn't work for pinctrl-st driver, due to missing irq_disable hook in the driver. disable_irq() is required only for level-triggered interrupts, which is not the case normally.

2015-01-07pinctrl: st: avoid multiple mutex lockFrancesco VIRLINZI
Using the sysfs inteface to inspect the pins configuration the system can walk around a path which acquires the same mutex twice. On STiH407 platform, for example : cat /sys/kernel/debug/pinctrl/920f080.pin-controller-front0/pinconf-pins hangs the kernel and never returns. With this patch the mutex is temporary freed.

2015-01-07gpio: dln2: fix issue when an IRQ is unmasked then enabledOctavian Purdila
As noticed during suspend/resume operations, the IRQ can be unmasked then disabled in suspend and eventually enabled in resume, but without being unmasked. The current implementation does not take into account interactions between mask/unmask and enable/disable interrupts, and thus in the above scenarios the IRQs remain unactive. To fix this we removed the enable/disable operations as they fallback to mask/unmask anyway. We also remove the pending bitmaks as it is already done in irq_data (i.e. IRQS_PENDING).

2015-01-07s390/timex: fix get_tod_clock_ext() inline assemblyChen Gang
For C language, it treats array parameter as a pointer, so sizeof for an array parameter is equal to sizeof for a pointer, which causes compiler warning (with allmodconfig by gcc 5): ./arch/s390/include/asm/timex.h: In function 'get_tod_clock_ext': ./arch/s390/include/asm/timex.h:76:32: warning: 'sizeof' on array function parameter 'clk' will return size of 'char *' [-Wsizeof-array-argument] typedef struct { char _[sizeof(clk)]; } addrtype; ^ Can use macro CLOCK_STORE_SIZE instead of all related hard code numbers, which also can avoid this warning. And also add a tab to CLOCK_TICK_RATE definition to match coding styles. [heiko.carstens@de.ibm.com]: Chen's patch actually fixes a bug within the get_tod_clock_ext() inline assembly where we incorrectly tell the compiler that only 8 bytes of memory get changed instead of 16 bytes. This would allow gcc to generate incorrect code. Right now this doesn't seem to be the case.

When the driver was polling with interrupts disabled the hardware will occasionally not write back descriptors. This patch causes the driver to detect this situation and force an interrupt to fire which will flush the stuck descriptor. Does not conflict with napi because if we are already polling the napi_schedule is ignored. Additionally the extra interrupts are rate limited, so don't cause a burden to the CPU.

2015-01-06netfilter: conntrack: fix race between confirmation and flushPablo Neira Ayuso
Commit 5195c14c8b27c ("netfilter: conntrack: fix race in __nf_conntrack_confirm against get_next_corpse") aimed to resolve the race condition between the confirmation (packet path) and the flush command (from control plane). However, it introduced a crash when several packets race to add a new conntrack, which seems easier to reproduce when nf_queue is in place. Fix this race, in __nf_conntrack_confirm(), by removing the CT from unconfirmed list before checking the DYING bit. In case race occured, re-add the CT to the dying list This patch also changes the verdict from NF_ACCEPT to NF_DROP when we lose race. Basically, the confirmation happens for the first packet that we see in a flow. If you just invoked conntrack -F once (which should be the common case), then this is likely to be the first packet of the flow (unless you already called flush anytime soon in the past). This should be hard to trigger, but better drop this packet, otherwise we leave things in inconsistent state since the destination will likely reply to this packet, but it will find no conntrack, unless the origin retransmits. The change of the verdict has been discussed in: https://www.marc.info/?l=linux-netdev&m=141588039530056&w=2 Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2015-01-06mm: propagate error from stack expansion even for guard pageLinus Torvalds
Jay Foad reports that the address sanitizer test (asan) sometimes gets confused by a stack pointer that ends up being outside the stack vma that is reported by /proc/maps. This happens due to an interaction between RLIMIT_STACK and the guard page: when we do the guard page check, we ignore the potential error from the stack expansion, which effectively results in a missing guard page, since the expected stack expansion won't have been done. And since /proc/maps explicitly ignores the guard page (commit d7824370e263: "mm: fix up some user-visible effects of the stack guard page"), the stack pointer ends up being outside the reported stack area. This is the minimal patch: it just propagates the error. It also effectively makes the guard page part of the stack limit, which in turn measn that the actual real stack is one page less than the stack limit. Let's see if anybody notices. We could teach acct_stack_growth() to allow an extra page for a grow-up/grow-down stack in the rlimit test, but I don't want to add more complexity if it isn't needed.

2015-01-06drm: imx: imx-hdmi: convert imx-hdmi to drm_bridge modeAndy Yan
IMX6 and Rockchip RK3288 and JZ4780 (Ingenic Xburst/MIPS) use the interface compatible Designware HDMI IP, but they also have some lightly differences, such as phy pll configuration, register width, 4K support, clk useage, and the crtc mux configuration is also platform specific. To reuse the imx hdmi driver, convert it to drm_bridge handle encoder in imx-hdmi_pltfm.c, as most of the encoder operation are platform specific such as crtc select and panel format set This patch depends on Russell King's patch: drm: imx: convert imx-drm to use the generic DRM OF helper http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2014-July/053484.html Signed-off-by: Andy Yan <andy.yan@rock-chips.com> Signed-off-by: Yakir Yang <ykk@rock-chips.com> Tested-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC globally in the IPU_CONF register, but the DC is used by multiple clients on different DC channels. So make sure to only disable/enable the DC globally based on a use counter. Signed-off-by: Steve Longerbeam <steve_longerbeam@mentor.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

2015-01-06virtio_pci: document why we defer kfreeMichael S. Tsirkin
The reason we defer kfree until release function is because it's a general rule for kobjects: kfree of the reference counter itself is only legal in the release function. Previous patch didn't make this clear, document this in code. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2015-01-06virtio_pci: defer kfree until release callbackSasha Levin
A struct device which has just been unregistered can live on past the point at which a driver decides to drop it's initial reference to the kobject gained on allocation. This implies that when releasing a virtio device, we can't free a struct virtio_device until the underlying struct device has been released, which might not happen immediately on device_unregister(). Unfortunately, this is exactly what virtio pci does: it has an empty release callback, and frees memory immediately after unregistering the device. This causes an easy to reproduce crash if CONFIG_DEBUG_KOBJECT_RELEASE it enabled. To fix, free the memory only once we know the device is gone in the release callback.
