2013-06-01parport_pc: disable PARPORT_PC_SUPERIO on parisc architectureHelge Deller
If enabled, CONFIG_PARPORT_PC_SUPERIO scans on PC-like hardware for various super-io chips by accessing i/o ports in a range which will crash any parisc hardware at once. In addition, parisc has it's own incompatible superio chip (CONFIG_SUPERIO), so if we disable PARPORT_PC_SUPERIO completely for parisc we can avoid that people by accident enable the parport_pc superio option too.

resources (v2) commit dc7dce280a Author: Bjorn Helgaas <bhelgaas@google.com> Date: Fri Oct 28 16:27:27 2011 -0600 parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus resources Supply root bus resources to pci_create_root_bus() so they're correct immediately. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. added tests for elmmio_space.start while it should use elmmio_space.flags. This for example led to incorrect resource assignments and a non-working stifb framebuffer on most parisc machines.

2013-05-31iscsi-target: Fix iscsit_free_cmd() se_cmd->cmd_kref shutdown handlingNicholas Bellinger
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>

2013-05-30aerdrv: Move cper_print_aer() call out of interrupt contextLance Ortiz
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.

2013-05-29ib_srpt: Call target_sess_cmd_list_set_waiting during shutdown_sessionNicholas Bellinger
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.

2013-05-29target: Re-instate sess_wait_list for target_wait_for_sess_cmdsNicholas Bellinger
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.

2013-05-29clk: samsung: Add CLK_IGNORE_UNUSED flag for the sysreg clocksSylwester Nawrocki
Currently no driver *) handles the sysreg clock, with an assumption that this clock is always left in its default state (enabled). 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. To restore the previous behaviour disable masking the sysreg clock off in the clock core by default. *) Except the Exynos4x12 FIMC-IS driver, which will be modified to not touch the sysreg clock.

2013-05-29clk: ux500: clk-sysctrl: handle clocks with no parentsFabio Baltieri
Fix clk_reg_sysctrl() to set main clock registers of new struct clk_sysctrl even if the registered clock has no parents. This fixes an issue where "ulpclk" was registered with all clk->reg_* fields uninitialized, causing a -EINVAL error from clk_prepare().

2013-05-29radeon: use max_bus_speed to activate gen2 speedsKleber Sacilotto de Souza
radeon currently uses a drm function to get the speed capabilities for the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard method of performing this detection and this patch changes it to use the max_bus_speed attribute.

2013-05-29drm/radeon: narrow scope of Apple re-POST hackAlex Deucher
This narrows the scope of the apple re-POST hack added in: drm/radeon: re-POST the asic on Apple hardware when booted via EFI That patch prevents UVD from working on macs when booted in EFI mode. The original patch fixed macbook2,1 systems which were r5xx and hence have no UVD. Limit the hack to those systems to prevent UVD breakage on newer systems.

Newer asics have variable numbers of crtcs. Use that rather than the asic family to determine which crtcs to check. This avoids checking non-existent crtcs or missing crtcs on certain asics.
