2014-09-01ASoC: simple-card: Fix bug of wrong decrement DT node's refcountXiubo Li
DAI links's cpu_of_node's and codec_of_node's refcounts shouldn't be decremented immediately at the end of the probe() fucntion. Because we will still use them before the audio card is removed. Signed-off-by: Xiubo Li <Li.Xiubo@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2014-09-01Revert "arm64: cpuinfo: print info for all CPUs"Will Deacon
It turns out that vendors are relying on the format of /proc/cpuinfo, and we've even spotted out-of-tree hacks attempting to make it look identical to the format used by arch/arm/. That means we can't afford to churn this interface in mainline, so revert the recent reformatting of the file for arm64 pending discussions on the list to find out what people actually want.

This patch refactors the digital port connected check out of the g4x detection path and reuses it in the hpd pulse path.

His device tree is like below: +-1c.4-[02]--+-00.0 JMicron Technology Corp. JMB363 SATA/IDE Controller | \-00.1 JMicron Technology Corp. JMB363 SATA/IDE Controller After investigation, we found the the Micron chip 363 included one SATA controller(0000:02:00.0) and one PATA controller(0000:02:00.1), these two controllers do not have parent-children relationship, but the PATA controller only can be powered on after the SATA controller has finished the powering on. If we enabled the async noirq(), then the below error is hit during noirq phase: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 Here for JMicron chip 363/361, we need forcedly to disable the async method.

2014-09-01arm64: fix bug for reloading FPSIMD state after cpu power offLeo Yan
Now arm64 defers reloading FPSIMD state, but this optimization also introduces the bug after cpu resume back from low power mode. The reason is after the cpu has been powered off, s/w need set the cpu's fpsimd_last_state to NULL so that it will force to reload FPSIMD state for the thread, otherwise there has the chance to meet the condition for both the task's fpsimd_state.cpu field contains the id of the current cpu, and the cpu's fpsimd_last_state per-cpu variable points to the task's fpsimd_state, so finally kernel will skip to reload the context during it return back to userland.

Sierra Wireless Direct IP devices using the 68A3 product ID can be configured for modes including a CDC ECM class function. The known example uses interface numbers 12 and 13 for the ECM control and data interfaces respectively, consistent with CDC MBIM function interface numbering on other Sierra devices. It seems cleaner to restrict this driver to the ff/ff/ff vendor specific interfaces rather than increasing the already long interface number blacklist. This should be more future proof if Sierra adds more class functions using interface numbers not yet in the blacklist.

So fix this for SCSI and add the required sysfs attributes for reading the IPL loadparm and for setting the loadparm for re-IPL. With this patch the following two sysfs attributes are introduced: - /sys/firmware/ipl/loadparm (for system that have been IPLed from SCSI) - /sys/firmware/reipl/fcp/loadparm Because the loadparm is now available for SCSI and CCW it is moved now from "struct ipl_block_ccw" to the generic "struct ipl_list_hdr".

2014-08-30fix EBUSY on umount() from MNT_SHRINKABLEAl Viro
We need the parents of victims alive until namespace_unlock() gets to dput() of the (ex-)mountpoints. However, that screws up the "is it busy" checks in case when we have shrinkable mounts that need to be killed. Solution: go ahead and decrement refcounts of parents right in umount_tree(), increment them again just before dropping rwsem in namespace_unlock() (and let the loop in the end of namespace_unlock() finally drop those references for good, as we do now). Parents can't get freed until we drop rwsem - at least one reference is kept until then, both in case when parent is among the victims and when it is not. So they'll still be around when we get to namespace_unlock(). Cc: stable@vger.kernel.org # 3.12+ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2014-08-29net: sctp: fix ABI mismatch through sctp_assoc_to_state helperDaniel Borkmann
Since SCTP day 1, that is, 19b55a2af145 ("Initial commit") from lksctp tree, the official <netinet/sctp.h> header carries a copy of enum sctp_sstat_state that looks like (compared to the current in-kernel enumeration): User definition: Kernel definition: enum sctp_sstat_state { typedef enum { SCTP_EMPTY = 0, <removed> SCTP_CLOSED = 1, SCTP_STATE_CLOSED = 0, SCTP_COOKIE_WAIT = 2, SCTP_STATE_COOKIE_WAIT = 1, SCTP_COOKIE_ECHOED = 3, SCTP_STATE_COOKIE_ECHOED = 2, SCTP_ESTABLISHED = 4, SCTP_STATE_ESTABLISHED = 3, SCTP_SHUTDOWN_PENDING = 5, SCTP_STATE_SHUTDOWN_PENDING = 4, SCTP_SHUTDOWN_SENT = 6, SCTP_STATE_SHUTDOWN_SENT = 5, SCTP_SHUTDOWN_RECEIVED = 7, SCTP_STATE_SHUTDOWN_RECEIVED = 6, SCTP_SHUTDOWN_ACK_SENT = 8, SCTP_STATE_SHUTDOWN_ACK_SENT = 7, }; } sctp_state_t; This header was later on also placed into the uapi, so that user space programs can compile without having <netinet/sctp.h>, but the shipped with <linux/sctp.h> instead. While RFC6458 under 8.2.1.Association Status (SCTP_STATUS) says that sstat_state can range from SCTP_CLOSED to SCTP_SHUTDOWN_ACK_SENT, we nevertheless have a what it appears to be dummy SCTP_EMPTY state from the very early days. While it seems to do just nothing, commit 0b8f9e25b0aa ("sctp: remove completely unsed EMPTY state") did the right thing and removed this dead code. That however, causes an off-by-one when the user asks the SCTP stack via SCTP_STATUS API and checks for the current socket state thus yielding possibly undefined behaviour in applications as they expect the kernel to tell the right thing. The enumeration had to be changed however as based on the current socket state, we access a function pointer lookup-table through this. Therefore, I think the best way to deal with this is just to add a helper function sctp_assoc_to_state() to encapsulate the off-by-one quirk.

2014-08-29net: attempt a single high order allocationEric Dumazet
In commit ed98df3361f0 ("net: use __GFP_NORETRY for high order allocations") we tried to address one issue caused by order-3 allocations. We still observe high latencies and system overhead in situations where compaction is not successful. Instead of trying order-3, order-2, and order-1, do a single order-3 best effort and immediately fallback to plain order-0. This mimics slub strategy to fallback to slab min order if the high order allocation used for performance failed. Order-3 allocations give a performance boost only if they can be done without recurring and expensive memory scan. Quoting David : The page allocator relies on synchronous (sync light) memory compaction after direct reclaim for allocations that don't retry and deferred compaction doesn't work with this strategy because the allocation order is always decreasing from the previous failed attempt. This means sync light compaction will always be encountered if memory cannot be defragmented or reclaimed several times during the skb_page_frag_refill() iteration.
