2013-01-11ARM: integrator: move syscon remap for AP PCIv3Linus Walleij
The Integrator/AP syscon remapping was done in the .setup() function rather than .preinit() which is wrong - .preinit() is called before .setup() and the former also use the syscon base and cause a crash since it was not yet remapped.

2013-01-11ath9k: fix rx flush handlingFelix Fietkau
Right now the rx flush is not doing anything useful on AR9003+, as it only works if the buffers in the rx FIFO have not been purged yet, as is done by ath_stoprecv. To fix this, always call ath_flushrecv from within ath_stoprecv before the FIFO is emptied, but still after the hw receive path has been stopped. This ensures that frames received (and ACKed by the hardware) shortly before a reset will be seen by the software, which should improve A-MPDU session stability.

2013-01-11ath9k: add a better fix for the rx tasklet vs rx flush raceFelix Fietkau
Ensure that the rx tasklet is no longer running when entering the reset path. Also remove the distinction between flush and no-flush frame processing. If a frame has been received and ACKed by the hardware, the stack needs to see it, so that the BA receive window does not go out of sync.

There is corner case in which we include zero rates in supported rates TLV based on previous IBSS network history, which leads to association failure.

2013-01-11mm: compaction: Partially revert capture of suitable high-order pageMel Gorman
Eric Wong reported on 3.7 and 3.8-rc2 that ppoll() got stuck when waiting for POLLIN on a local TCP socket. It was easier to trigger if there was disk IO and dirty pages at the same time and he bisected it to commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available"). The intention of that patch was to improve high-order allocations under memory pressure after changes made to reclaim in 3.6 drastically hurt THP allocations but the approach was flawed. For Eric, the problem was that page->pfmemalloc was not being cleared for captured pages leading to a poor interaction with swap-over-NFS support causing the packets to be dropped. However, I identified a few more problems with the patch including the fact that it can increase contention on zone->lock in some cases which could result in async direct compaction being aborted early. In retrospect the capture patch took the wrong approach. What it should have done is mark the pageblock being migrated as MIGRATE_ISOLATE if it was allocating for THP and avoided races that way. While the patch was showing to improve allocation success rates at the time, the benefit is marginal given the relative complexity and it should be revisited from scratch in the context of the other reclaim-related changes that have taken place since the patch was first written and tested. This patch partially reverts commit 1fb3f8ca "mm: compaction: capture a suitable high-order page immediately when it is made available".

When the driver is built-in, the missing semicolon after structure initializer is "compensated" by MODULE_DEVICE_TABLE() macro being empty and so the initializer using the trailing semicolon on the next line; when the driver is built as a module, compilation error ensues, and as the 'davinci_all_defconfig' has the NAND driver modular, this error prevents DaVinci family kernel from building...

2013-01-11f2fs: add f2fs_balance_fs in several interfacesJaegeuk Kim
The f2fs_balance_fs() is to check the number of free sections and decide whether it needs to conduct cleaning or not. If there are not enough free sections, the cleaning job should be started. In order to control an amount of free sections even under high utilization, f2fs should call f2fs_balance_fs at all the VFS interfaces that are able to produce dirty pages. This patch adds the function calls in the missing interfaces as follows. 1. f2fs_setxattr() The f2fs_setxattr() produces dirty node pages so that we should call f2fs_balance_fs() either likewise doing in other VFS interfaces such as f2fs_lookup(), f2fs_mkdir(), and so on. 2. f2fs_sync_file() We should guarantee serving free sections for syncing metadata during fsync. Previously, there is no space check before triggering checkpoint and sync_node_pages. Therefore, if a bunch of fsync calls are triggered under 100% of FS utilization, f2fs is able to be faced with no free sections, resulting in BUG_ON(). 3. f2fs_sync_fs() Before calling write_checkpoint(), we should guarantee that there are minimum free sections. 4. f2fs_write_inode() f2fs_write_inode() is also able to produce dirty node pages.

2013-01-10target: Fix use-after-free in LUN RESET handlingRoland Dreier
If a backend IO takes a really long then an initiator might abort a command, and then when it gives up on the abort, send a LUN reset too, all before we process any of the original command or the abort. (The abort will wait for the backend IO to complete too) When the backend IO final completes (or fails), the abort handling will proceed and queue up a "return aborted status" operation. Then, while that's still pending, the LUN reset might find the original command still on the LUN's list of commands and try to return aborted status again, which leads to a use-after free when the first se_tfo->queue_status call frees the command and then the second se_tfo->queue_status call runs. Fix this by removing a command from the LUN state_list when we first are about to queue aborted status; we shouldn't do anything LUN-related after we've started returning status, so this seems like the correct thing to do.

2013-01-10target: Fix missing CMD_T_ACTIVE bit regression for pending WRITEsRoland Dreier
This patch fixes a regression bug introduced during v3.6.x code with the following commit to drop transport_add_cmd_to_queue(), which originally re-set CMD_T_ACTIVE during pending WRITE I/O submission: commit af8772926f019b7bddd7477b8de5f3b0f12bad21 Author: Christoph Hellwig <hch@infradead.org> Date: Sun Jul 8 15:58:49 2012 -0400 target: replace the processing thread with a TMR work queue The following sequence happens for write commands (or any other commands with a data out phase): - The transport calls target_submit_cmd(), which sets CMD_T_ACTIVE in cmd->transport_state and sets cmd->t_state to TRANSPORT_NEW_CMD. - Things go on transport_generic_new_cmd(), which notices that the command needs to transfer data, so it sets cmd->t_state to TRANSPORT_WRITE_PENDING and calls transport_cmd_check_stop(). - transport_cmd_check_stop() clears CMD_T_ACTIVE in cmd->transport_state and returns in the normal case. - Then we continue on to call ->se_tfo->write_pending(). - The data comes back from the initiator, and the transport calls target_execute_cmd(), which sets cmd->t_state to TRANSPORT_PROCESSING and calls into the backend to actually write the data. At this point, the backend might take a long time to complete the command, since it has to do real IO. If an abort request comes in for this command at this point, it will not wait for the command to finish since CMD_T_ACTIVE is not set. Then when the command does finally finish, we blow up with use-after-free. Avoid this by setting CMD_T_ACTIVE in target_execute_cmd() so that transport_wait_for_tasks() waits for the command to finish executing. This matches the behavior from before commit 1389533ef944 ("target: remove transport_generic_handle_data"), when data was signaled via transport_generic_handle_data(), which set CMD_T_ACTIVE because it called transport_add_cmd_to_queue().

2013-01-10net: ethernet: xilinx: Do not use NO_IRQ in axienetMichal Simek
This driver is used on Microblaze and will be used on Arm Zynq. Microblaze doesn't define NO_IRQ and no IRQ is 0. Arm still uses NO_IRQ as -1 and there is no option to connect IRQ to irq 0. That's why <= 0 is only one option how to find out undefined IRQ. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10net: ethernet: xilinx: Do not use axienet on PPCMichal Simek
Axi ethernet can't be used on PPC because it is little endian IP and PPC is big endian. This system can't be designed. Signed-off-by: Michal Simek <michal.simek@xilinx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-01-10bnx2x: Allow management traffic after boot from SANBarak Witkowski
As part of the previous driver unload flow, whenever bnx2x is loaded after the UNDI driver it closes all Rx traffic. However, this leads to management traffic also being stopped until the network interface associated with one of its functions gets loaded. To remedy this, management traffic is re-opened once the 'cleaning' after the previous driver ends.

2013-01-10bnx2x: Fix fastpath structures when memory allocation failsYuval Mintz
When allocating Tx queues, if for some reason (e.g., lack of memory) allocation fails, driver will incorrectly calculate the pointers of the various queues. This patch repositions all pointers in such a case to point at sequential structures in memory, allowing the bnx2x macros to be used correctly when accessing them.

2013-01-10bfin_mac: Restore hardware time-stamping dependency on BF518Lars-Peter Clausen
Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware time-stamping is only available on BF518 though. Since the Kconfig entry is 'default y', just updateing your kernel source and running `make defconfig` will result in the the following build errors: drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’ drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’ drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’ drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’ ... This patch adds back the dependency on BF518, and since it does not make sense to expose this config option when the blackfin MAC driver is not enabled also restore the dependency on BFIN_MAC.

2013-01-10tun: avoid owner checks on IFF_ATTACH_QUEUEMichael S. Tsirkin
At the moment, we check owner when we enable queue in tun. This seems redundant and will break some valid uses where fd is passed around: I think TUNSETOWNER is there to prevent others from attaching to a persistent device not owned by them. Here the fd is already attached, enabling/disabling queue is more like read/write. Signed-off-by: Michael S.

2013-01-10tuntap: refuse to re-attach to different tun_structStefan Hajnoczi
Multiqueue tun devices support detaching a tun_file from its tun_struct and re-attaching at a later point in time. This allows users to disable a specific queue temporarily. ioctl(TUNSETIFF) allows the user to specify the network interface to attach by name. This means the user can attempt to attach to interface "B" after detaching from interface "A". The driver is not designed to support this so check we are re-attaching to the right tun_struct. Failure to do so may lead to oops. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
