2012-04-26mISDN: DSP scheduling fix (version 2)Karsten Keil2-2/+4
dsp_spl_jiffies need to be the same datatype as jiffies (which is ulong). If not, on 64 bit systems it will fallback to schedule the DSP every jiffie tic as soon jiffies become > 2^32. Signed-off-by: Karsten Keil <kkeil@linux-pingi.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-04-23bnx2x: add afex supportBarak Witkowski14-57/+1081
Following patch adds afex multifunction support to the driver (afex multifunction is based on vntag header) and updates FW version used to 7.2.51. Support includes the following: 1. Configure vif parameters in firmware (default vlan, vif id, default priority, allowed priorities) according to values received from NIC. 2. Configure FW to strip/add default vlan according to afex vlan mode. 3. Notify link up to OS only after vif is fully initialized. 4. Support vif list set/get requests and configure FW accordingly. 5. Supply afex statistics upon request from NIC. 6. Special handling to L2 interface in case of FCoE vif.

Moving to interrupts instead of polling fpr TX completions Avoiding situations where skb can be held in by the driver for a long time (till timer expires). The change is also necessary for supporting BQL. Removing comp_lock that was required because we could handle TX completions from several contexts: Interrupts, timer, polling.

2012-04-24md: fix possible corruption of array metadata on shutdown.NeilBrown1-1/+2
commit c744a65c1e2d59acc54333ce8 md: don't set md arrays to readonly on shutdown. removed the possibility of a 'BUG' when data is written to an array that has just been switched to read-only, but also introduced the possibility that the array metadata could be corrupted. If, when md_notify_reboot gets the mddev lock, the array is in a state where it is assembled but hasn't been started (as can happen if the personality module is not available, or in other unusual situations), then incorrect metadata will be written out making it impossible to re-assemble the array. So only call __md_stop_writes() if the array has actually been activated. This patch is needed for any stable kernel which has had the above commit applied.

2012-04-24md: don't call ->add_disk unless there is good reason.NeilBrown1-2/+2
Commit 7bfec5f35c68121e7b18 md/raid5: If there is a spare and a want_replacement device, start replacement. cause md_check_recovery to call ->add_disk much more often. Instead of only when the array is degraded, it is now called whenever md_check_recovery finds anything useful to do, which includes updating the metadata for clean<->dirty transition. This causes unnecessary work, and causes info messages from ->add_disk to be reported much too often. So refine md_check_recovery to only do any actual recovery checking (including ->add_disk) if MD_RECOVERY_NEEDED is set.

Although the network interface is down, the RX packets number which could be observed by ifconfig may keep on increasing. This is because the WORK scheduled in netvsc_set_multicast_list() may be executed after netvsc_close(). That means the rndis filter may be re-enabled by do_set_multicast() even if it was closed by netvsc_close(). By canceling possible WORK before close the rndis filter, the issue could be never happened.

2012-04-21ks8851: Fix mutex deadlock in ks8851_net_stop()Stephen Boyd1-5/+6
There is a potential deadlock scenario when the ks8851 driver is removed. The interrupt handler schedules a workqueue which acquires a mutex that ks8851_net_stop() also acquires before flushing the workqueue. Previously lockdep wouldn't be able to find this problem but now that it has the support we can trigger this lockdep warning by rmmoding the driver after an ifconfig up. Fix the possible deadlock by disabling the interrupts in the chip and then release the lock across the workqueue flushing. The mutex is only there to proect the registers anyway so this should be ok. ======================================================= [ INFO: possible circular locking dependency detected ] 3.0.21-00021-g8b33780-dirty #2911 ------------------------------------------------------- rmmod/125 is trying to acquire lock: ((&ks->irq_work)){+.+...}, at: [<c019e0b8>] flush_work+0x0/0xac but task is already holding lock: (&ks->lock){+.+...}, at: [<bf00b850>] ks8851_net_stop+0x64/0x138 [ks8851] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #1 (&ks->lock){+.+...}: [<c01b89c8>] __lock_acquire+0x940/0x9f8 [<c01b9058>] lock_acquire+0x10c/0x130 [<c083dbec>] mutex_lock_nested+0x68/0x3dc [<bf00bd48>] ks8851_irq_work+0x24/0x46c [ks8851] [<c019c580>] process_one_work+0x2d8/0x518 [<c019cb98>] worker_thread+0x220/0x3a0 [<c01a2ad4>] kthread+0x88/0x94 [<c0107008>] kernel_thread_exit+0x0/0x8 -> #0 ((&ks->irq_work)){+.+...}: [<c01b7984>] validate_chain+0x914/0x1018 [<c01b89c8>] __lock_acquire+0x940/0x9f8 [<c01b9058>] lock_acquire+0x10c/0x130 [<c019e104>] flush_work+0x4c/0xac [<bf00b858>] ks8851_net_stop+0x6c/0x138 [ks8851] [<c06b209c>] __dev_close_many+0x98/0xcc [<c06b2174>] dev_close_many+0x68/0xd0 [<c06b22ec>] rollback_registered_many+0xcc/0x2b8 [<c06b2554>] rollback_registered+0x28/0x34 [<c06b25b8>] unregister_netdevice_queue+0x58/0x7c [<c06b25f4>] unregister_netdev+0x18/0x20 [<bf00c1f4>] ks8851_remove+0x64/0xb4 [ks8851] [<c049ddf0>] spi_drv_remove+0x18/0x1c [<c0468e98>] __device_release_driver+0x7c/0xbc [<c0468f64>] driver_detach+0x8c/0xb4 [<c0467f00>] bus_remove_driver+0xb8/0xe8 [<c01c1d20>] sys_delete_module+0x1e8/0x27c [<c0105ec0>] ret_fast_syscall+0x0/0x3c other info that might help us debug this: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(&ks->lock); lock((&ks->irq_work)); lock(&ks->lock); lock((&ks->irq_work)); *** DEADLOCK *** 4 locks held by rmmod/125: #0: (&__lockdep_no_validate__){+.+.+.}, at: [<c0468f44>] driver_detach+0x6c/0xb4 #1: (&__lockdep_no_validate__){+.+.+.}, at: [<c0468f50>] driver_detach+0x78/0xb4 #2: (rtnl_mutex){+.+.+.}, at: [<c06b25e8>] unregister_netdev+0xc/0x20 #3: (&ks->lock){+.+...}, at: [<bf00b850>] ks8851_net_stop+0x64/0x138 [ks8851] Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: David S.

2012-04-21caif: include linux/io.hArnd Bergmann1-0/+4
The caif_shmcore requires io.h in order to use ioremap, so include that explicitly to compile in all configurations. Also add a note about the use of ioremap(), which is not a proper way to map a DMA buffer into kernel space. It's not completely clear what the intention is for using ioremap, but it is clear that the result of ioremap must not simply be accessed using kernel pointers but should use readl/writel or memcopy_{to,from}io. Assigning the result of ioremap to a regular pointer that can also be set to something else is not ok.

2012-04-21drivers/net: add missing __devexit_p() annotationsArnd Bergmann3-3/+3
Drivers that refer to a __devexit function in an operations structure need to annotate that pointer with __devexit_p so replace it with a NULL pointer when the section gets discarded.

The davinci_emac driver can be a module, so the symbols it needs from the cpdma driver must be exported. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-21pch_gbe: remove suspicious commentRichard Cochran1-1/+0
The time stamping code in this driver appears to have been copied from the ixp4xx_eth.c driver, including this timing comment. I had actually measured the time stamp delay on an IXP425, but I really doubt that this value also applies here. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2012-04-21pch_gbe: run the ptp bpf just once per packetRichard Cochran1-3/+1
This patch fixes code which needlessly ran the BPF twice per packet. Instead, we just run the classifier once and test whether the packet is any kind of PTP event message. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-04-21pch_gbe: correct receive time stamp filteringTakahiro Shimizu2-4/+20
This patch fixes the driver so that multicast PTP event messages can be recognized by the hardware time stamping unit. The station address register must be set according to the desired transport type.
