Pull sparc updates from David Miller: 1) Kill off support for sun4c and Cypress sun4m chips. And as a result we were able to also kill off that ugly btfixup thing that required multi-stage links of the final vmlinux image in the Kbuild system. This should make the kbuild maintainers really happy. Thanks a lot to Sam Ravnborg for his tireless efforts to get this going. 2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot cleaner, it should be able to fall in line and modernize in this area too. 3) Make sparc32 use generic clockevents, from Tkhai Kirill. [ I fixed up the BPF rules, and tried to clean up the build rules too.

Pull networking changes from David Miller: 1) Get rid of the error prone NLA_PUT*() macros that used an embedded goto. 2) Kill off the token-ring and MCA networking drivers, from Paul Gortmaker. 3) Reduce high-order allocations made by datagram AF_UNIX sockets, from Eric Dumazet. 4) Add PTP hardware clock support to IGB and IXGBE, from Richard Cochran and Jacob Keller. 5) Allow users to query timestamping capabilities of a card via ethtool, from Richard Cochran. 6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part of this is that we can now have BPF filters not attached to sockets, and the loadbalancing function is calculated using one. 7) Francois Romieu went through the network drivers removing gratuitous uses of netdev->base_addr, perhaps some day we can remove it completely but it's used for ISA probing still. 8) Add a BPF JIT for sparc. I know, who cares, right? :-) 9) Move networking sysctl registry away from using the compatability mode interfaces in the sysctl code. From Eric W Biederman. 10) Pavel Emelyanov added a way to save and restore TCP socket state via TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as well as a way to forcefully bind a socket to a port via the sk->sk_reuse value SK_FORCE_REUSE. There is also a TCP_REPAIR_OPTIONS which allows to reinstante the TCP options enabled on the connection. 11) Several enhancements from Eric Dumazet that, in particular, can enhance splice performance on TCP sockets significantly. a) Reset the offset of the per-socket sendmsg page when we know we're the only use of the page in linear_to_page(). b) Add facilities such that skb->data can be backed a page rather than SLAB kmalloc'd memory. In particular devices which were receiving into linear RX buffers can now end up providing paged data. The big result is that code like splice and GRO do not have to copy any more. 12) Allow a pure sender to more gracefully handle ACK backlogs in TCP. What can happen at high rates is that the sender hasn't grown his receive buffer limits at all (he's not receiving data so really doesn't need to), but the non-data ACKs consume receive buffer space. sk_add_backlog() is too aggressive in dropping frames in this case, so relax it's requirements by using the receive buffer plus the send buffer limit as the backlog limit instead of just the former. Also from Eric Dumazet. 13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and Chris Elston. 14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng. Basically, we can start fast retransmit before hiting the dupack threshold under certain conditions. 15) New CODEL active queue management packet scheduler, from Eric Dumazet based upon initial work by Dave Taht. Basically, the big feature is that packets are dropped (or ECN bits are set) based upon how long packets live in the queue, rather than the queue length (which is what RED uses). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1341 commits) drivers/net/stmmac: seq_file fix memory leak ipv6/exthdrs: strict Pad1 and PadN check USB: qmi_wwan: Add ZTE (Vodafone) K3520-Z USB: qmi_wwan: Add ZTE (Vodafone) K3765-Z USB: qmi_wwan: Make forced int 4 whitelist generic net/ipv4: replace simple_strtoul with kstrtoul net/ipv4/ipconfig: neaten __setup placement net: qmi_wwan: Add Vodafone/Huawei K5005 support net: cdc_ether: Add ZTE WWAN matches before generic Ethernet ipv6: use skb coalescing in reassembly ipv4: use skb coalescing in defragmentation net: introduce skb_try_coalesce() net:ipv6:fixed space issues relating to operators. net:ipv6:fixed a trailing white space issue. ipv6: disable GSO on sockets hitting dst_allfrag tg3: use netdev_alloc_frag() API net: napi_frags_skb() is static ppp: avoid false drop_monitor false positives ipv6: bool/const conversions phase2 ipx: Remove spurious NULL checking in ipx_ioctl(). ...

2012-05-21xhci: Fix compile with CONFIG_USB_SUSPEND=nSarah Sharp
The USB 2.0 Link PM code is conditionally compiled when CONFIG_USB_SUSPEND=y. I believe that's a mistake, since Link PM is not directly related to USB device suspend and Link PM is implemented without relying on any of the suspend code in the USB core. For now, keep the USB 2.0 Link PM code conditionally compiled if CONFIG_USB_SUSPEND=y. This patch does move the code to implement USB 3.0 Link PM out of the xHCI driver #ifdefs for CONFIG_USB_SUSPEND and moves it into a section dependent on CONFIG_PM. The USB core functions for USB 3.0 Link PM are already conditionally compiled when CONFIG_PM=y. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>

This teaches vfs_fstat() to use the appropriate f[get|put]_light functions, allowing it to avoid some unnecessary locking for the common case. More noticeably, it also cleans up and simplifies the "getname_flags()" function, which now relies on the architecture strncpy_from_user() doing all the user access checks properly, instead of hacking around the fact that on x86 it didn't use to do it right (see commit 92ae03f2ef99: "x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). * vfs-cleanups: VFS: make vfs_fstat() use f[get|put]_light() VFS: clean up and simplify getname_flags() x86: make word-at-a-time strncpy_from_user clear bytes at the end

This makes cp_new_stat() a bit more readable, and avoids having to memset() the whole structure just to fill in a couple of padding fields. This is another result of me looking at code generation of functions that show up high on certain kernel profiles, and just going "Oh, let's just clean that up". Architectures that don't supply the #define to fill just the padding fields will still fall back to memset(). * stat-cleanups: vfs: don't force a big memset of stat data just to clear padding fields vfs: de-crapify "cp_new_stat()" function
2012-05-21Merge branch 'vm-cleanups' (unmap_vma() interface cleanup)Linus Torvalds
This series sanitizes the interface to unmap_vma(). The crazy interface annoyed me no end when I was looking at unmap_single_vma(), which we can spend quite a lot of time in (especially with loads that have a lot of small fork/exec's: shell scripts etc). Moving the nr_accounted calculations to where they belong at least clarifies things a little. I hope to come back to look at the performance of this later, but if/when I get back to it I at least don't have to see the crazy interfaces any more. * vm-cleanups: vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces vm: simplify unmap_vmas() calling convention

2012-05-21Merge tag 'isci-for-3.5' into miscJames Bottomley
isci update for 3.5 1/ Rework remote-node-context (RNC) handling for proper management of the silicon state machine in error handling and hot-plug conditions. Further details below, suffice to say if the RNC is mismanaged the silicon state machines may lock up. 2/ Refactor the initialization code to be reused for suspend/resume support 3/ Miscellaneous bug fixes to address discovery issues and hardware compatibility. RNC rework details from Jeff Skirvin: In the controller, devices as they appear on a SAS domain (or direct-attached SATA devices) are represented by memory structures known as "Remote Node Contexts" (RNCs). These structures are transferred from main memory to the controller using a set of register commands; these commands include setting up the context ("posting"), removing the context ("invalidating"), and commands to control the scheduling of commands and connections to that remote device ("suspensions" and "resumptions"). There is a similar path to control RNC scheduling from the protocol engine, which interprets the results of command and data transmission and reception. In general, the controller chooses among non-suspended RNCs to find one that has work requiring scheduling the transmission of command and data frames to a target. Likewise, when a target tries to return data back to the initiator, the state of the RNC is used by the controller to determine how to treat the incoming request. As an example, if the RNC is in the state "TX/RX Suspended", incoming SSP connection requests from the target will be rejected by the controller hardware. When an RNC is "TX Suspended", it will not be selected by the controller hardware to start outgoing command or data operations (with certain priority-based exceptions). As mentioned above, there are two sources for management of the RNC states: commands from driver software, and the result of transmission and reception conditions of commands and data signaled by the controller hardware. As an example of the latter, if an outgoing SSP command ends with a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will transition to the "TX Suspended" state, and this is signaled by the controller hardware in the status to the completion of the pending command as well as signaled in a controller hardware event. Examples of the former are included in the patch changelogs. Driver software is required to suspend the RNC in a "TX/RX Suspended" condition before any outstanding commands can be terminated. Failure to guarantee this can lead to a complete hardware hang condition. Earlier versions of the driver software did not guarantee that an RNC was correctly managed before I/O termination, and so operated in an unsafe way. Further, the driver performed unnecessary contortions to preserve the remote device command state and so was more complicated than it needed to be. A simplifying driver assumption is that once an I/O has entered the error handler path without having completed in the target, the requirement on the driver is that all use of the sas_task must end. Beyond that, recovery of operation is dependent on libsas and other components to reset, rediscover and reconfigure the device before normal operation can restart. In the driver, this simplifying assumption meant that the RNC management could be reduced to entry into the suspended state, terminating the targeted I/O request, and resuming the RNC as needed for device-specific management such as an SSP Abort Task or LUN Reset Management request.

2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.

2012-05-21UBI: modify ubi_wl_flush function to clear work queue for a lnumJoel Reardon
This patch modifies ubi_wl_flush to force the erasure of particular volume id / logical eraseblock number pairs. Previous functionality is preserved when passing UBI_ALL for both values. The locations where ubi_wl_flush were called are appropriately changed: ubi_leb_erase only flushes for the erased LEB, and ubi_create_volume forces only flushing for its volume id. External code can call this new feature via the new function ubi_flush() added to kapi.c, which simply passes through to ubi_wl_flush(). This was tested by disabling the call to do_work in ubi thread, which results in the work queue remaining unless explicitly called to remove. UBIFS was changed to call ubifs_leb_change 50 times for four different LEBs. Then the new function was called to clear the queue: passing wrong volume ids / lnum, correct ones, and finally UBI_ALL for both to ensure it was finally all cleard. The work queue was dumped each time and the selective removal of the particular LEB numbers was observed. Extra checks were enabled and ubifs's integck was also run.

2012-05-21UBI: introduce UBI_ALL constantArtem Bityutskiy
Joel will use it in his 'ubi_flush()' extention to specify all eraseblocks. Also amend the comment for UBI_UNKNOWN - it is used beyond attaching info structure now. Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
2012-05-21UBI: add lnum and vol_id to struct ubi_workJoel Reardon
This is part of a multipart patch to allow UBI to force the erasure of particular logical eraseblock numbers. In this patch, the volume id and LEB number are added to ubi_work data structure, and both are also passed as a parameter to schedule erase to set it appropriately. Whenever ubi_wl_put_peb is called, the lnum is also passed to be forwarded to schedule erase. Later, a new ubi_sync_lnum will be added to execute immediately all work related to that lnum. This was tested by outputting the vol_id and lnum during the schedule of erasure. The ubi thread was disabled and two ubifs drives on separate partitions repeated changed a small number of LEBs. The ubi module was readded, and all the erased LEBs, corresponding to the volumes, were added to the schedule erase queue.

2012-05-21UBI: add volume id struct ubi_ainf_pebJoel Reardon
This patch adds the volume id to struct ubi_ainf_peb when scanning the LEBs at startup. PEBs now added to the erase queue will know their original LEB number and volume id, if available, and will be -1 otherwise (for instance, if the VID header is unreadable). This was tested by creating an ubi device with 3 volumes and disabiling the ubi_thread's do_work functionality. The different ubi volumes were formatted to ubifs and had files created and erased. The ubi modules was reloaded and the list of LEB's added to the erased list was outputted, confirming the volume ids and LEB numbers were appropriate.
