2012-12-03libata: implement ata_platform_remove_one()Brian Norris
This relatively simple boiler-plate code is repeated in several platform drivers. We should implement a common version in libata. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2012-12-03libata: check SATA_SETTINGS log with HW Feature CtrlShane Huang
NCQ capability was used to check availability of SATA Settings page from Identify Device Data Log, which contains DevSlp timing variables. It does not work on some HDDs and leads to error messages. IDENTIFY word 78 bit 5(Hardware Feature Control) should be used. Quoting SATA spec 3.1: If Hardware Feature Control is supported, then: a) IDENTIFY DEVICE data word 78 bit 5 (see 13.2.1.18) shall be set to one; b) the SET FEATURES Select Hardware Feature Control subcommand shall be supported (see 13.3.8); c) page 08h of the Identify Device Data log (see 13.7.7) shall be supported; This patch is not tested on SATA HDD with DevSlp supported.

2012-12-03libata: restore acpi disable functionalityAaron Lu
Commit 66fa7f215 "libata-acpi: improve ACPI disabling" introdcued the behaviour of disabling ATA ACPI if ata_acpi_on_devcfg failed the 2nd time, but commit 30dcf76ac dropped this behaviour and this caused problem for Dimitris Damigos, where his laptop can not resume correctly. The bugzilla page for it is: https://bugzilla.kernel.org/show_bug.cgi?id=49331 The problem is, ata_dev_push_id will fail the 2nd time it is invoked, and due to disabling ACPI code is dropped, ata_acpi_on_devcfg which calls ata_dev_push_id will keep failing and eventually made the device disabled. This patch restores the original behaviour, if acpi failed the 2nd time, disable acpi functionality for the device(and we do not event need to add a debug message for this as it is still there ;-).

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu Conflicts: arch/x86/kernel/ptrace.c Pull the latest RCU tree from Paul E. McKenney: " The major features of this series are: 1. A first version of no-callbacks CPUs. This version prohibits offlining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU=y. Relaxing this constraint is in progress, but not yet ready for prime time. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/724, and are at branch rcu/nocb. 2. Changes to SRCU that allows statically initialized srcu_struct structures. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/296, and are at branch rcu/srcu. 3. Restructuring of RCU's debugfs output. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/341, and are at branch rcu/tracing. 4. Additional CPU-hotplug/RCU improvements, posted to LKML at https://lkml.org/lkml/2012/10/30/327, and are at branch rcu/hotplug. Note that the commit eliminating __stop_machine() was judged to be too-high of risk, so is deferred to 3.9. 5. Changes to RCU's idle interface, most notably a new module parameter that redirects normal grace-period operations to their expedited equivalents. These were posted to LKML at https://lkml.org/lkml/2012/10/30/739, and are at branch rcu/idle. 6. Additional diagnostics for RCU's CPU stall warning facility, posted to LKML at https://lkml.org/lkml/2012/10/30/315, and are at branch rcu/stall. The most notable change reduces the default RCU CPU stall-warning time from 60 seconds to 21 seconds, so that it once again happens sooner than the softlockup timeout. 7. Documentation updates, which were posted to LKML at https://lkml.org/lkml/2012/10/30/280, and are at branch rcu/doc. A couple of late-breaking changes were posted at https://lkml.org/lkml/2012/11/16/634 and https://lkml.org/lkml/2012/11/16/547. 8. Miscellaneous fixes, which were posted to LKML at https://lkml.org/lkml/2012/10/30/309, along with a late-breaking change posted at Fri, 16 Nov 2012 11:26:25 -0800 with message-ID <20121116192625.GA447@linux.vnet.ibm.com>, but which lkml.org seems to have missed. These are at branch rcu/fixes. 9. Finally, a fix for an lockdep-RCU splat was posted to LKML at https://lkml.org/lkml/2012/11/7/486. This is at rcu/next.

The immediate use case for this is that it will allow us to ensure that a pppoatm queue is woken after it has to drop a packet due to the sock being locked. Note that 'release_cb' is called when the socket is *unlocked*. This is not to be confused with vcc_release() — which probably ought to be called vcc_close().

2012-11-30net: move inet_dport/inet_num in sock_commonEric Dumazet
commit 68835aba4d9b (net: optimize INET input path further) moved some fields used for tcp/udp sockets lookup in the first cache line of struct sock_common. This patch moves inet_dport/inet_num as well, filling a 32bit hole on 64 bit arches and reducing number of cache line misses in lookups. Also change INET_MATCH()/INET_TW_MATCH() to perform the ports match before addresses match, as this check is more discriminant. Remove the hash check from MATCH() macros because we dont need to re validate the hash value after taking a refcount on socket, and use likely/unlikely compiler hints, as the sk_hash/hash check makes the following conditional tests 100% predicted by cpu. Introduce skc_addrpair/skc_portpair pair values to better document the alignment requirements of the port/addr pairs used in the various MATCH() macros, and remove some casts. The namespace check can also be done at last. This slightly improves TCP/UDP lookup times. IP/TCP early demux needs inet->rx_dst_ifindex and TCP needs inet->min_ttl, lets group them together in same cache line. With help from Ben Hutchings & Joe Perches. Idea of this patch came after Ling Ma proposal to move skc_hash to the beginning of struct sock_common, and should allow him to submit a final version of his patch. My tests show an improvement doing so.

This is an abstraction of some RCU code that use such tracking to implement its userspace extended quiescent state.

2012-11-30ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.hTony Lindgren
Based on earlier discussions[1] we attempted to find a suitable location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP: DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion to dmaengine is complete. Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

2012-11-30cfg80211: fix BSS struct IE access racesJohannes Berg
When a BSS struct is updated, the IEs are currently overwritten or freed. This can lead to races if some other CPU is accessing the BSS struct and using the IEs concurrently. Fix this by always allocating the IEs in a new struct that holds the data and length and protecting access to this new struct with RCU. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-11-30mfd: tps65910: Remove unused dataKim, Milo
The 'io_mutex' is not used anywhere. The regmap API supports the mutex internally, so no additional mutex is required. And 'domain' private data is unnecessary because the irq domain is already registered by using regmap_add_irq_chip().
