Change the indicator from 0xffffffff in the "event_id" member to zero in the "cntr_mask" member. This removes the need to initialize entries that are unsupported. This also solves a problem where the number of entries in the table was increased based on a globel enum used for all platforms, but the new unsupported entries were not added for mips. This was leaving new table entries of all zeros that we not marked UNSUPPORTED. Signed-off-by:

We can save an instruction in the TLB Refill path for kernel mappings by aligning swapper_pg_dir on a 64K boundary. The address of swapper_pg_dir can be generated with a single LUI instead of LUI/{D}ADDUI. The alignment of __init_end is bumped up to 64K so there are no holes between it and swapper_pg_dir, which is placed at the very beginning of .bss. The alignment of invalid_pmd_table and invalid_pte_table can be relaxed to PAGE_SIZE. We do this by using __page_aligned_bss, which has the added benefit of eliminating alignment holes in .bss.

I've maintained this patch, originally from Thiemo Seufer in 2004, for a really long time, but I think it's time for it to get a look at for possible inclusion. I have had no problems with it across various SGI systems over the years. To quote the post here: http://www.linux-mips.org/archives/linux-mips/2004-12/msg00000.html "the atomic functions use so far memory references for the inline assembler to access the semaphore. This can lead to additional instructions in the ll/sc loop, because newer compilers don't expand the memory reference any more but leave it to the assembler. The appended patch uses registers instead, and makes the ll/sc arguments more explicit. In some cases it will lead also to better register scheduling because the register isn't bound to an output any more." Signed-off-by:

Pull i2c-embedded changes from Wolfram Sang: "The changes for i2c-embedded include: - massive rework of the omap driver - massive rework of the at91 driver. In fact, the old driver gets removed; I am okay with this approach since the old driver was depending on BROKEN and its limitations made it practically unusable, so people used bitbanging instead. But even if there are users, there is no platform_data or module parameter which would need to be converted. It is just another driver doing I2C transfers, just way better. Modifications of arch/arm/at91 related files have proper acks from the maintainer. - new driver for R-Car I2C - devicetree and generic_clock conversions and fixes - usual driver fixes and changes. The rework patches have come a long way and lots of people have been involved in creating/testing them. Most patches have been in linux-next at least since 3.6-rc5. A few have been added in the last week, I have to admit. An unexpected (but welcome :)) peak in private life is the cause for that. The "late" patches shouldn't cause any merge conflicts and I will have a special eye on them during the stabilization phase. This is an exception and I want to have the patches in place properly in time again for the next kernels." * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (44 commits) MXS: Implement DMA support into mxs-i2c i2c: add Renesas R-Car I2C driver i2c: s3c2410: use clk_prepare_enable and clk_disable_unprepare ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints i2c: nomadik: Add Device Tree support to the Nomadik I2C driver i2c: algo: pca: Fix chip reset function for PCA9665 i2c: mpc: Wait for STOP to hit the bus i2c: davinci: preparation for switch to common clock framework omap-i2c: fix incorrect log message when using a device tree i2c: omap: sanitize exit path i2c: omap: switch over to autosuspend API i2c: omap: remove unnecessary pm_runtime_suspended check i2c: omap: switch to threaded IRQ support i2c: omap: remove redundant status read i2c: omap: get rid of the "complete" label i2c: omap: resize fifos before each message i2c: omap: simplify IRQ exit path i2c: omap: always return IRQ_HANDLED i2c: omap: simplify errata check i2c: omap: bus: add a receiver flag ...

In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING mount pending flag is not cleared. One effect of this is when using the "browse" option, directory entry attributes show up with all "?"s due to the incorrect callback and subsequent failure return (when in fact no callback should be made).

Commit 6b8029fa ("rtc: kconfig: remove unnecessary dependencies") removed various 'depends on RTC_CLASS' dependencies but also removed a few 'default RTC_CLASS' statements, which actually changed default behavior. This resulted in the various RTC interfaces (sysfs, proc, dev) all being disabled by default, even when RTC_CLASS is enabled: # CONFIG_RTC_INTF_SYSFS is not set # CONFIG_RTC_INTF_PROC is not set # CONFIG_RTC_INTF_DEV is not set which is different from previous behavior (all of these where enabled.) To fix, add back the 'default RTC_CLASS' statments to each of the RTC_INTF_* options. I noticed this because some RTC tests started failing on my TI OMAP platforms because /dev/rtc0 was not present anymore, even though the driver was present and RTC_CLASS was enabled. Signed-off-by:

The virq_disabled flag tracks the userspace view of INTx masking across interrupt mode changes, but we're not consistently applying this to the interrupt and masking handler notion of the device. Currently if the user sets DisINTx while in MSI or MSIX mode, then returns to INTx mode (ex. rebooting a qemu guest), the hardware has DisINTx+, but the management of INTx thinks it's enabled, making it impossible to actually clear DisINTx. Fix this by updating the handler state when INTx is re-enabled. Cc: stable@vger.kernel.org Signed-off-by:

Pull pwm changes from Thierry Reding: "All legacy PWM providers have now been moved to the PWM subsystem. The plan for 3.8 is to adapt all board files to provide a lookup table for PWM devices in order to get rid of the global namespace. Subsequently, users of the legacy pwm_request() and pwm_free() functions can be migrated to the new pwm_get() and pwm_put() functions. Once this has been completed, the legacy API and the compatibility code in the core can be removed. In addition to the above, these changes also add support for configuring the polarity of a PWM signal (currently only supported on ECAP and EHRPWM) and include a much needed rework of the i.MX driver. Managed functions to obtain and release a PWM device (devm_pwm_get() and devm_pwm_put()) have been added and the pwm-backlight driver has been updated to use them. If the PWM subsystem hasn't been enabled, dummy functions are provided that allow the subsystem to safely compile out. Some common checks on input parameters have been moved to the core and removed from the drivers. Finally, a small fix corrects the description of the PWM specifier's second cell in the device tree representation." * tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm: (23 commits) pwm: dt: Fix description of second PWM cell pwm: Check for negative duty-cycle and period pwm: Add Ingenic JZ4740 support MIPS: JZ4740: Export timer API pwm: Move PUV3 PWM driver to PWM framework unicore32: pwm: Use managed resource allocations unicore32: pwm: Remove unnecessary indirection unicore32: pwm: Use module_platform_driver() unicore32: pwm: Properly remap memory-mapped registers pwm-backlight: Use devm_pwm_get() instead of pwm_get() pwm: Move AB8500 PWM driver to PWM framework pwm: Fix compilation error when CONFIG_PWM is not defined pwm: i.MX: fix clock lookup pwm: i.MX: use per clock unconditionally pwm: i.MX: add devicetree support pwm: i.MX: Use module_platform_driver pwm: i.MX: add functions to enable/disable pwm. pwm: i.MX: remove unnecessary if in pwm_[en|dis]able pwm: i.MX: factor out SoC specific functions pwm: pwm-tiehrpwm: Add support for configuring polarity of PWM ...

The highlights include: - target: Simplify fabric sense data length handling (roland) - qla2xxx: Fix endianness of task management response code (roland) - target: fix truncation of mode data, support zero allocation length (paolo) - target: Properly support zero-length commands in normal processing path (paolo) - iscsi-target: Correctly set 0xffffffff field within ISCSI_OP_REJECT PDU (ronnie + nab) - iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG demo-mode (ronnie + nab) - target/file: Re-enable optional fd_buffered_io=1 operation (nab + hch) - iscsi-target: Add MaxXmitDataSegmenthLength forr target -> initiator MDRSL declaration (nab) - target: Add target_submit_cmd_map_sgls for SGL fabric memory passthrough (nab + hch) - tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls (hch + nab) - tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls (nab + hch) The last series for adding a new target_submit_cmd_map_sgls() fabric caller (as requested by hch) that accepts pre-allocated SGL memory (using existing logic), along with converting tcm_loop + tcm_vhost has only been in -next for the last days, but has gotten enough review +testing and is clear enough a mechanical change that I think it's reasonable to merge for -rc1 code. Thanks again to everyone who contributed this round! Extra special thanks to Roland (PureStorage) for tracking down the qla2xxx target TMR response code endian issue, and to Paolo (Redhat) for resolving the long standing zero-length CDB issues within target-core between virtual and pSCSI backends." * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (44 commits) iscsi-target: Bump defaults for nopin_timeout + nopin_response_timeout values iscsit: proper endianess conversions iscsit: use the itt_t abstract type iscsit: add missing endianess conversion in iscsit_check_inaddr_any iscsit: remove incorrect unlock in iscsit_build_sendtargets_resp iscsit: mark various functions static target/iscsi: precedence bug in iscsit_set_dataout_sequence_values() target/usb-gadget: strlen() doesn't count the terminator target/usb-gadget: remove duplicate initialization tcm_vhost: Convert I/O path to use target_submit_cmd_map_sgls target: Add control CDB READ payload zero work-around tcm_loop: Convert I/O path to use target_submit_cmd_map_sgls target: Add target_submit_cmd_map_sgls for SGL fabric memory passthrough iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG demo-mode iscsi-target: Change iscsi_target_seq_pdu_list.c to honor MaxXmitDataSegmentLength iscsi-target: Add MaxXmitDataSegmentLength connection recovery check iscsi-target: Convert incoming PDU payload checks to MaxXmitDataSegmentLength iscsi-target: Enable MaxXmitDataSegmentLength operation in login path iscsi-target: Add base MaxXmitDataSegmentLength code target/file: Re-enable optional fd_buffered_io=1 operation ...

Pull networking updates from David Miller: 1) UAPI changes for networking from David Howells 2) A netlink dump is an operation we can sleep within, and therefore we need to make sure the dump provider module doesn't disappear on us meanwhile. Fix from Gao Feng. 3) Now that tunnels support GRO, we have to be more careful in skb_gro_reset_offset() otherwise we OOPS, from Eric Dumazet. 4) We can end up processing packets for VLANs we aren't actually configured to be on, fix from Florian Zumbiehl. 5) Fix routing cache removal regression in redirects and IPVS. The core issue on the IPVS side is that it wants to rewrite who the nexthop is and we have to explicitly accomodate that case. From Julian Anastasov. 6) Error code return fixes all over the networking drivers from Peter Senna Tschudin. 7) Fix routing cache removal regressions in IPSEC, from Steffen Klassert. 8) Fix deadlock in RDS during pings, from Jeff Liu. 9) Neighbour packet queue can trigger skb_under_panic() because we do not reset the network header of the SKB in the right spot. From Ramesh Nagappa. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (61 commits) RDS: fix rds-ping spinlock recursion netdev/phy: Prototype of_mdio_find_bus() farsync: fix support for over 30 cards be2net: Remove code that stops further access to BE NIC based on UE bits pch_gbe: Fix build error by selecting all the possible dependencies. e1000e: add device IDs for i218 ixgbe/ixgbevf: Limit maximum jumbo frame size to 9.5K to avoid Tx hangs ixgbevf: Set the netdev number of Tx queues UAPI: (Scripted) Disintegrate include/linux/tc_ematch UAPI: (Scripted) Disintegrate include/linux/tc_act UAPI: (Scripted) Disintegrate include/linux/netfilter_ipv6 UAPI: (Scripted) Disintegrate include/linux/netfilter_ipv4 UAPI: (Scripted) Disintegrate include/linux/netfilter_bridge UAPI: (Scripted) Disintegrate include/linux/netfilter_arp UAPI: (Scripted) Disintegrate include/linux/netfilter/ipset UAPI: (Scripted) Disintegrate include/linux/netfilter UAPI: (Scripted) Disintegrate include/linux/isdn UAPI: (Scripted) Disintegrate include/linux/caif net: fix typo in freescale/ucc_geth.c vxlan: fix more sparse warnings ...
