2013-06-12input: ti_am335x_tsc: ACK the HW_PEN irq in ISRSebastian Andrzej Siewior1-0/+6
The interrupt source IRQENB_HW_PEN is enabled in suspend and suposed to be used as a wake up source. Once this interrupt source is unmaksed, the devices ends up in ISR and never continues. This change ACKs the interrupt and disables it so the system does not freeze. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
2013-06-12input: ti_am335x_adc: use only FIFO0 and clean up a littleSebastian Andrzej Siewior2-38/+42
The driver programs a threshold of "coordinate_readouts" say 5. The REG_FIFO0THR registers says it should it be programmed to "threshold minus one". The driver does not expect just 5 coordinates but 5 * 2 + 2. Multiplied by two because 5 for X and 5 for Y and plus 2 because we have two Z. The whole thing kind of works because It reads the 5 coordinates for X and Y from FIFO0 and FIFO1 and the last element in each FIFO is ignored within the loop and read later. Nothing guaranties that FIFO1 is ready by the time it is read. In fact I could see that that FIFO1 reaturns for Y channels 8,9, 10, 12, 6 and for Y channel 7 for Z. The problem is that channel 7 and channel 12 got somehow mixed up. The other Problem is that FIFO1 is also used by the IIO part leading to wrong results if both (tsc & adc) are used. The patch tries to clean up the whole thing a little: - Remove the +1 and -1 in REG_STEPCONFIG, REG_STEPDELAY and its counter part in the for loop. This is just confusing. - Use only FIFO0 in TSC. The fifo has space for 64 entries so should be fine. - Read the whole FIFO in one function and check the channel. - in case we dawdle around, make sure we only read a multiple of our coordinate set. On the second interrupt we will cleanup the remaining enties. Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

Current code has hard coded value written to step enable bits. Now the bits are updated based on how many steps are needed to be configured got from platform data. The user needs to take care not to exceed the count more than 16. While using ADC and TSC one should take care to set this parameter correctly.

2013-06-12mfd: input: iio: ti_am335x_adc: use one structure for ti_tscadc_devSebastian Andrzej Siewior3-13/+16
The mfd driver creates platform data for the child devices and it is the ti_tscadc_dev struct. This struct is copied for the two devices. The copy of the structure makes a common lock in this structure a little less usefull. Therefore the platform data is not a pointer to the structure and the same structure is used. While doing the change I noticed that the suspend/resume code assumes the wrong pointer for ti_tscadc_dev and this has been fixed as well.

2013-05-31iscsi-target: Fix iscsit_free_cmd() se_cmd->cmd_kref shutdown handlingNicholas Bellinger4-26/+50
With the introduction of target_get_sess_cmd() referencing counting for ISCSI_OP_SCSI_CMD processing with iser-target, iscsit_free_cmd() usage in traditional iscsi-target driver code now needs to be aware of the active I/O shutdown case when a remaining se_cmd->cmd_kref reference may exist after transport_generic_free_cmd() completes, requiring a final target_put_sess_cmd() to release iscsi_cmd descriptor memory. This patch changes iscsit_free_cmd() to invoke __iscsit_free_cmd() before transport_generic_free_cmd() -> target_put_sess_cmd(), and also avoids aquiring the per-connection queue locks for typical fast-path calls during normal ISTATE_REMOVE operation. Also update iscsit_free_cmd() usage throughout iscsi-target to use the new 'bool shutdown' parameter. This patch fixes a regression bug introduced during v3.10-rc1 in commit 3e1c81a95, that was causing the following WARNING to appear: [ 257.235153] ------------[ cut here]------------ [ 257.240314] WARNING: at kernel/softirq.c:160 local_bh_enable_ip+0x3c/0x86() [ 257.248089] Modules linked in: vhost_scsi ib_srpt ib_cm ib_sa ib_mad ib_core tcm_qla2xxx tcm_loop tcm_fc libfc iscsi_target_mod target_core_pscsi target_core_file target_core_iblock target_core_mod configfs ipv6 iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi loop acpi_cpufreq freq_table mperf kvm_intel kvm crc32c_intel button ehci_pci pcspkr joydev i2c_i801 microcode ext3 jbd raid10 raid456 async_pq async_xor xor async_memcpy async_raid6_recov raid6_pq async_tx raid1 raid0 linear igb hwmon i2c_algo_bit i2c_core ptp ata_piix libata qla2xxx uhci_hcd ehci_hcd mlx4_core scsi_transport_fc scsi_tgt pps_core [ 257.308748] CPU: 1 PID: 3295 Comm: iscsi_ttx Not tainted 3.10.0-rc2+ #103 [ 257.316329] Hardware name: Intel Corporation S5520HC/S5520HC, BIOS S5500.86B.01.00.0057.031020111721 03/10/2011 [ 257.327597] ffffffff814c24b7 ffff880458331b58 ffffffff8138eef2 ffff880458331b98 [ 257.335892] ffffffff8102c052 ffff880400000008 0000000000000000 ffff88085bdf0000 [ 257.344191] ffff88085bdf00d8 ffff88085bdf00e0 ffff88085bdf00f8 ffff880458331ba8 [ 257.352488] Call Trace: [ 257.355223] [<ffffffff8138eef2>] dump_stack+0x19/0x1f [ 257.360963] [<ffffffff8102c052>] warn_slowpath_common+0x62/0x7b [ 257.367669] [<ffffffff8102c080>] warn_slowpath_null+0x15/0x17 [ 257.374181] [<ffffffff81032345>] local_bh_enable_ip+0x3c/0x86 [ 257.380697] [<ffffffff813917fd>] _raw_spin_unlock_bh+0x10/0x12 [ 257.387311] [<ffffffffa029069c>] iscsit_free_r2ts_from_list+0x5e/0x67 [iscsi_target_mod] [ 257.396438] [<ffffffffa02906c5>] iscsit_release_cmd+0x20/0x223 [iscsi_target_mod] [ 257.404893] [<ffffffffa02977a4>] lio_release_cmd+0x3a/0x3e [iscsi_target_mod] [ 257.412964] [<ffffffffa01d59a1>] target_release_cmd_kref+0x7a/0x7c [target_core_mod] [ 257.421712] [<ffffffffa01d69bc>] target_put_sess_cmd+0x5f/0x7f [target_core_mod] [ 257.430071] [<ffffffffa01d6d6d>] transport_release_cmd+0x59/0x6f [target_core_mod] [ 257.438625] [<ffffffffa01d6eb4>] transport_put_cmd+0x131/0x140 [target_core_mod] [ 257.446985] [<ffffffffa01d6192>] ? transport_wait_for_tasks+0xfa/0x1d5 [target_core_mod] [ 257.456121] [<ffffffffa01d6f11>] transport_generic_free_cmd+0x4e/0x52 [target_core_mod] [ 257.465159] [<ffffffff81050537>] ? __migrate_task+0x110/0x110 [ 257.471674] [<ffffffffa02904ba>] iscsit_free_cmd+0x46/0x55 [iscsi_target_mod] [ 257.479741] [<ffffffffa0291edb>] iscsit_immediate_queue+0x301/0x353 [iscsi_target_mod] [ 257.488683] [<ffffffffa0292f7e>] iscsi_target_tx_thread+0x1c6/0x2a8 [iscsi_target_mod] [ 257.497623] [<ffffffff81047486>] ? wake_up_bit+0x25/0x25 [ 257.503652] [<ffffffffa0292db8>] ? iscsit_ack_from_expstatsn+0xd5/0xd5 [iscsi_target_mod] [ 257.512882] [<ffffffff81046f89>] kthread+0xb0/0xb8 [ 257.518329] [<ffffffff81046ed9>] ? kthread_freezable_should_stop+0x60/0x60 [ 257.526105] [<ffffffff81396fec>] ret_from_fork+0x7c/0xb0 [ 257.532133] [<ffffffff81046ed9>] ? kthread_freezable_should_stop+0x60/0x60 [ 257.539906] ---[ end trace 5520397d0f2e0800 ]--- Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

2013-05-31iscsi-target: fix heap buffer overflow on errorKees Cook2-6/+6
If a key was larger than 64 bytes, as checked by iscsi_check_key(), the error response packet, generated by iscsi_add_notunderstood_response(), would still attempt to copy the entire key into the packet, overflowing the structure on the heap. Remote preauthentication kernel memory corruption was possible if a target was configured and listening on the network.

2013-05-31target/file: Fix off-by-one READ_CAPACITY bug for !S_ISBLK exportNicholas Bellinger1-5/+6
This patch fixes a bug where FILEIO was incorrectly reporting the number of logical blocks (+ 1) when using non struct block_device export mode. It changes fd_get_blocks() to follow all other backend ->get_blocks() cases, and reduces the calculated dev_size by one dev->dev_attrib.block_size number of bytes, and also fixes initial fd_block_size assignment at fd_configure_device() time introduced in commit 0fd97ccf4.

2013-05-30aerdrv: Move cper_print_aer() call out of interrupt contextLance Ortiz4-22/+9
The following warning was seen on 3.9 when a corrected PCIe error was being handled by the AER subsystem. WARNING: at .../drivers/pci/search.c:214 pci_get_dev_by_id+0x8a/0x90() This occurred because a call to pci_get_domain_bus_and_slot() was added to cper_print_pcie() to setup for the call to cper_print_aer(). The warning showed up because cper_print_pcie() is called in an interrupt context and pci_get* functions are not supposed to be called in that context. The solution is to move the cper_print_aer() call out of the interrupt context and into aer_recover_work_func() to avoid any warnings when calling pci_get* functions.

2013-05-30ib_srpt: Call target_sess_cmd_list_set_waiting during shutdown_sessionNicholas Bellinger2-8/+25
Given that srpt_release_channel_work() calls target_wait_for_sess_cmds() to allow outstanding se_cmd_t->cmd_kref a change to complete, the call to perform target_sess_cmd_list_set_waiting() needs to happen in srpt_shutdown_session() Also, this patch adds an explicit call to srpt_shutdown_session() within srpt_drain_channel() so that target_sess_cmd_list_set_waiting() will be called in the cases where TFO->shutdown_session() is not triggered directly by TCM.

2013-05-30target: Re-instate sess_wait_list for target_wait_for_sess_cmdsNicholas Bellinger1-4/+14
Switch back to pre commit 1c7b13fe652 list splicing logic for active I/O shutdown with tcm_qla2xxx + ib_srpt fabrics. The original commit was done under the incorrect assumption that it's safe to walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting() during session shutdown. So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to allow wait_for_completion() + TFO->release_cmd() to occur without having to walk ->sess_cmd_list after the list_splice. Also add a check to exit if target_sess_cmd_list_set_waiting() has already been called, and add a WARN_ON to check for any fabric bug where new se_cmds are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already been set.

Before commit 6e6aac7590f902d14d90bace3fd499 ARM: EXYNOS: Migrate clock support to common clock framework the sysreg clock was not even defined and hence wasn't handled explicitly in the kernel.
