2015-05-14sched / idle: Call idle_set_state() from cpuidle_enter_state()Rafael J. Wysocki
Introduce a wrapper function around idle_set_state() called sched_idle_set_state() that will pass this_rq() to it as the first argument and make cpuidle_enter_state() call the new function before and after entering the target state. At the same time, remove direct invocations of idle_set_state() from call_cpuidle(). This will allow the invocation of default_idle_call() to be moved from call_cpuidle() to cpuidle_enter_state() safely and call_cpuidle() to be simplified a bit as a result. Signed-off-by: Rafael J.

2015-05-14netfilter: add netfilter ingress hook after handle_ing() under unique static keyPablo Neira
This patch adds the Netfilter ingress hook just after the existing tc ingress hook, that seems to be the consensus solution for this. Note that the Netfilter hook resides under the global static key that enables ingress filtering. Nonetheless, Netfilter still also has its own static key for minimal impact on the existing handle_ing(). * Without this patch: Result: OK: 6216490(c6216338+d152) usec, 100000000 (60byte,0frags) 16086246pps 7721Mb/sec (7721398080bps) errors: 100000000 42.46% kpktgend_0 [kernel.kallsyms] [k] __netif_receive_skb_core 25.92% kpktgend_0 [kernel.kallsyms] [k] kfree_skb 7.81% kpktgend_0 [pktgen] [k] pktgen_thread_worker 5.62% kpktgend_0 [kernel.kallsyms] [k] ip_rcv 2.70% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_internal 2.34% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_sk 1.44% kpktgend_0 [kernel.kallsyms] [k] __build_skb * With this patch: Result: OK: 6214833(c6214731+d101) usec, 100000000 (60byte,0frags) 16090536pps 7723Mb/sec (7723457280bps) errors: 100000000 41.23% kpktgend_0 [kernel.kallsyms] [k] __netif_receive_skb_core 26.57% kpktgend_0 [kernel.kallsyms] [k] kfree_skb 7.72% kpktgend_0 [pktgen] [k] pktgen_thread_worker 5.55% kpktgend_0 [kernel.kallsyms] [k] ip_rcv 2.78% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_internal 2.06% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_sk 1.43% kpktgend_0 [kernel.kallsyms] [k] __build_skb * Without this patch + tc ingress: tc filter add dev eth4 parent ffff: protocol ip prio 1 \ u32 match ip dst 4.3.2.1/32 Result: OK: 9269001(c9268821+d179) usec, 100000000 (60byte,0frags) 10788648pps 5178Mb/sec (5178551040bps) errors: 100000000 40.99% kpktgend_0 [kernel.kallsyms] [k] __netif_receive_skb_core 17.50% kpktgend_0 [kernel.kallsyms] [k] kfree_skb 11.77% kpktgend_0 [cls_u32] [k] u32_classify 5.62% kpktgend_0 [kernel.kallsyms] [k] tc_classify_compat 5.18% kpktgend_0 [pktgen] [k] pktgen_thread_worker 3.23% kpktgend_0 [kernel.kallsyms] [k] tc_classify 2.97% kpktgend_0 [kernel.kallsyms] [k] ip_rcv 1.83% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_internal 1.50% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_sk 0.99% kpktgend_0 [kernel.kallsyms] [k] __build_skb * With this patch + tc ingress: tc filter add dev eth4 parent ffff: protocol ip prio 1 \ u32 match ip dst 4.3.2.1/32 Result: OK: 9308218(c9308091+d126) usec, 100000000 (60byte,0frags) 10743194pps 5156Mb/sec (5156733120bps) errors: 100000000 42.01% kpktgend_0 [kernel.kallsyms] [k] __netif_receive_skb_core 17.78% kpktgend_0 [kernel.kallsyms] [k] kfree_skb 11.70% kpktgend_0 [cls_u32] [k] u32_classify 5.46% kpktgend_0 [kernel.kallsyms] [k] tc_classify_compat 5.16% kpktgend_0 [pktgen] [k] pktgen_thread_worker 2.98% kpktgend_0 [kernel.kallsyms] [k] ip_rcv 2.84% kpktgend_0 [kernel.kallsyms] [k] tc_classify 1.96% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_internal 1.57% kpktgend_0 [kernel.kallsyms] [k] netif_receive_skb_sk Note that the results are very similar before and after. I can see gcc gets the code under the ingress static key out of the hot path. Then, on that cold branch, it generates the code to accomodate the netfilter ingress static key.

In ACPI processor drivers, we use direct comparisons of cpu logical id with -1 which are error prone in case logical cpuid is accidentally assinged an error code and prevents us from returning an error-encoding cpuid directly in some cases. So introduce invalid_logical_cpuid() to identify cpu with invalid logical cpu num, then it will be used to replace the direct comparisons with -1.

Four minor merge conflicts: 1) qca_spi.c renamed the local variable used for the SPI device from spi_device to spi, meanwhile the spi_set_drvdata() call got moved further up in the probe function. 2) Two changes were both adding new members to codel params structure, and thus we had overlapping changes to the initializer function. 3) 'net' was making a fix to sk_release_kernel() which is completely removed in 'net-next'. 4) In net_namespace.c, the rtnl_net_fill() call for GET operations had the command value fixed, meanwhile 'net-next' adjusted the argument signature a bit.

2015-05-13usb: add bus type for USB ULPIHeikki Krogerus
UTMI+ Low Pin Interface (ULPI) is a commonly used PHY interface for USB 2.0. The ULPI specification describes a standard set of registers which the vendors can extend for their specific needs. ULPI PHYs provide often functions such as charger detection and ADP sensing and probing. There are two major issues that the bus type is meant to tackle: Firstly, ULPI registers are accessed from the controller. The bus provides convenient method for the controller drivers to share that access with the actual PHY drivers. Secondly, there are already platforms that assume ULPI PHYs are runtime detected, such as many Intel Baytrail based platforms. They do not provide any kind of hardware description for the ULPI PHYs like separate ACPI device object that could be used to enumerate a device from.

Add support for the AXP22x PMIC devices to the existing AXP20x driver. This includes the AXP221 and AXP223, which are identical except for the external data bus. Only AXP221 is added for now. AXP223 will be added after it's Reduced Serial Bus (RSB) interface is supported. AXP22x defines a new set of registers, power supplies and regulators, but most of the API is similar to the AXP20x ones. A new irq chip definition is used, even though the available interrupts on AXP22x is a subset of those on AXP20x. This is done so the interrupt numbers match those on the datasheet. This patch only enables the interrupts, system power-off function, and PEK sub-device. The regulator driver must first support different variants before we enable it from the mfd driver.

2015-05-13ktime: Fix ktime_divns to do signed divisionJohn Stultz
It was noted that the 32bit implementation of ktime_divns() was doing unsigned division and didn't properly handle negative values. And when a ktime helper was changed to utilize ktime_divns, it caused a regression on some IR blasters. See the following bugzilla for details: https://bugzilla.redhat.com/show_bug.cgi?id=1200353 This patch fixes the problem in ktime_divns by checking and preserving the sign bit, and then reapplying it if appropriate after the division, it also changes the return type to a s64 to make it more obvious this is expected. Nicolas also pointed out that negative dividers would cause infinite loops on 32bit systems, negative dividers is unlikely for users of this function, but out of caution this patch adds checks for negative dividers for both 32-bit (BUG_ON) and 64-bit(WARN_ON) versions to make sure no such use cases creep in.

2015-05-12net: deinline netif_tx_stop_all_queues(), remove WARN_ON in ↵Denys Vlasenko
netif_tx_stop_queue() These functions compile to 60 bytes of machine code each. With this .config: http://busybox.net/~vda/kernel_config there are 617 calls of netif_tx_stop_queue() and 49 calls of netif_tx_stop_all_queues() in vmlinux. To fix this, remove WARN_ON in netif_tx_stop_queue() as suggested by davem, and deinline netif_tx_stop_all_queues().

2015-05-13crypto: aead - Convert top level interface to new styleHerbert Xu
This patch converts the top-level aead interface to the new style. All user-level AEAD interface code have been moved into crypto/aead.h. The allocation/free functions have switched over to the new way of allocating tfms. This patch also removes the double indrection on setkey so the indirection now exists only at the alg level. Apart from these there are no user-visible changes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-05-12PM / sleep: Add macro to define common noirq system PM callbacksGrygorii Strashko
The same approach is used as for the existing SET_SYSTEM_SLEEP_PM_OPS, but for noirq callbacks. New SET_NOIRQ_SYSTEM_SLEEP_PM_OPS, defined for CONFIG_PM_SLEEP, will point ->suspend_noirq, ->freeze_noirq and ->poweroff_noirq to the same function. Vice versa happens for ->resume_noirq, ->thaw_noirq and ->restore_noirq.
