2011-11-11tuner_xc2028: Allow selection of the frequency adjustment code for XC3028Mauro Carvalho Chehab
commit 9bed77ee2fb46b74782d0d9d14b92e9d07f3df6e upstream. This device is not using the proper demod IF. Instead of using the IF macro, it is specifying a IF frequency. This doesn't work, as xc3028 needs to load an specific SCODE for the tuner. In this case, there's no IF table for 5 MHz.

2011-11-11uvcvideo: Set alternate setting 0 on resume if the bus has been resetMing Lei
commit d59a7b1dbce8b972ec2dc9fcaaae0bfa23687423 upstream. If the bus has been reset on resume, set the alternate setting to 0. This should be the default value, but some devices crash or otherwise misbehave if they don't receive a SET_INTERFACE request before any other video control request.

Following on Herton's patch "fb: avoid possible deadlock caused by fb_set_suspend" which moves lock_fb_info() out of fb_set_suspend() to its callers, correct sh-mobile's locking around call to fb_set_suspend() and the same sort of deaklocks with console_lock() due to order of taking the lock. console_lock() must be taken while fb_info is already locked and fb_info must be locked while calling fb_set_suspend().

2011-11-11fb: avoid possible deadlock caused by fb_set_suspendHerton Ronaldo Krzesinski
commit 9e769ff3f585db8f978f9113be83d36c7e3965dd upstream. A lock ordering issue can cause deadlocks: in framebuffer/console code, all needed struct fb_info locks are taken before acquire_console_sem(), in places which need to take console semaphore. But fb_set_suspend is always called with console semaphore held, and inside it we call lock_fb_info which gets the fb_info lock, inverse locking order of what the rest of the code does. This causes a real deadlock issue, when we write to state fb sysfs attribute (which calls fb_set_suspend) while a framebuffer is being unregistered by remove_conflicting_framebuffers, as can be shown by following show blocked state trace on a test program which loads i915 and runs another forked processes writing to state attribute: Test process with semaphore held and trying to get fb_info lock: .. fb-test2 D 0000000000000000 0 237 228 0x00000000 ffff8800774f3d68 0000000000000082 00000000000135c0 00000000000135c0 ffff880000000000 ffff8800774f3fd8 ffff8800774f3fd8 ffff880076ee4530 00000000000135c0 ffff8800774f3fd8 ffff8800774f2000 00000000000135c0 Call Trace: [<ffffffff8141287a>] __mutex_lock_slowpath+0x11a/0x1e0 [<ffffffff814142f2>] ? _raw_spin_lock_irq+0x22/0x40 [<ffffffff814123d3>] mutex_lock+0x23/0x50 [<ffffffff8125dfc5>] lock_fb_info+0x25/0x60 [<ffffffff8125e3f0>] fb_set_suspend+0x20/0x80 [<ffffffff81263e2f>] store_fbstate+0x4f/0x70 [<ffffffff812e7f70>] dev_attr_store+0x20/0x30 [<ffffffff811c46b4>] sysfs_write_file+0xd4/0x160 [<ffffffff81155a26>] vfs_write+0xc6/0x190 [<ffffffff81155d51>] sys_write+0x51/0x90 [<ffffffff8100c012>] system_call_fastpath+0x16/0x1b .. modprobe process stalled because has the fb_info lock (got inside unregister_framebuffer) but waiting for the semaphore held by the test process which is waiting to get the fb_info lock: .. modprobe D 0000000000000000 0 230 218 0x00000000 ffff880077a4d618 0000000000000082 0000000000000001 0000000000000001 ffff880000000000 ffff880077a4dfd8 ffff880077a4dfd8 ffff8800775a2e20 00000000000135c0 ffff880077a4dfd8 ffff880077a4c000 00000000000135c0 Call Trace: [<ffffffff81411fe5>] schedule_timeout+0x215/0x310 [<ffffffff81058051>] ? get_parent_ip+0x11/0x50 [<ffffffff814130dd>] __down+0x6d/0xb0 [<ffffffff81089f71>] down+0x41/0x50 [<ffffffff810629ac>] acquire_console_sem+0x2c/0x50 [<ffffffff812ca53d>] unbind_con_driver+0xad/0x2d0 [<ffffffff8126f5f7>] fbcon_event_notify+0x457/0x890 [<ffffffff814144ff>] ? _raw_spin_unlock_irqrestore+0x1f/0x50 [<ffffffff81058051>] ? get_parent_ip+0x11/0x50 [<ffffffff8141836d>] notifier_call_chain+0x4d/0x70 [<ffffffff8108a3b8>] __blocking_notifier_call_chain+0x58/0x80 [<ffffffff8108a3f6>] blocking_notifier_call_chain+0x16/0x20 [<ffffffff8125dabb>] fb_notifier_call_chain+0x1b/0x20 [<ffffffff8125e6ac>] unregister_framebuffer+0x7c/0x130 [<ffffffff8125e8b3>] remove_conflicting_framebuffers+0x153/0x180 [<ffffffff8125eef3>] register_framebuffer+0x93/0x2c0 [<ffffffffa0331112>] drm_fb_helper_single_fb_probe+0x252/0x2f0 [drm_kms_helper] [<ffffffffa03314a3>] drm_fb_helper_initial_config+0x2f3/0x6d0 [drm_kms_helper] [<ffffffffa03318dd>] ? drm_fb_helper_single_add_all_connectors+0x5d/0x1c0 [drm_kms_helper] [<ffffffffa037b588>] intel_fbdev_init+0xa8/0x160 [i915] [<ffffffffa0343d74>] i915_driver_load+0x854/0x12b0 [i915] [<ffffffffa02f0e7e>] drm_get_pci_dev+0x19e/0x360 [drm] [<ffffffff8141821d>] ? sub_preempt_count+0x9d/0xd0 [<ffffffffa0386f91>] i915_pci_probe+0x15/0x17 [i915] [<ffffffff8124481f>] local_pci_probe+0x5f/0xd0 [<ffffffff81244f89>] pci_device_probe+0x119/0x120 [<ffffffff812eccaa>] ? driver_sysfs_add+0x7a/0xb0 [<ffffffff812ed003>] driver_probe_device+0xa3/0x290 [<ffffffff812ed1f0>] ? __driver_attach+0x0/0xb0 [<ffffffff812ed29b>] __driver_attach+0xab/0xb0 [<ffffffff812ed1f0>] ? __driver_attach+0x0/0xb0 [<ffffffff812ebd3e>] bus_for_each_dev+0x5e/0x90 [<ffffffff812ecc2e>] driver_attach+0x1e/0x20 [<ffffffff812ec6f2>] bus_add_driver+0xe2/0x320 [<ffffffffa03aa000>] ? i915_init+0x0/0x96 [i915] [<ffffffff812ed536>] driver_register+0x76/0x140 [<ffffffffa03aa000>] ? i915_init+0x0/0x96 [i915] [<ffffffff81245216>] __pci_register_driver+0x56/0xd0 [<ffffffffa02f1264>] drm_pci_init+0xe4/0xf0 [drm] [<ffffffffa03aa000>] ? i915_init+0x0/0x96 [i915] [<ffffffffa02e84a8>] drm_init+0x58/0x70 [drm] [<ffffffffa03aa094>] i915_init+0x94/0x96 [i915] [<ffffffff81002194>] do_one_initcall+0x44/0x190 [<ffffffff810a066b>] sys_init_module+0xcb/0x210 [<ffffffff8100c012>] system_call_fastpath+0x16/0x1b .. fb-test2 which reproduces above is available on kernel.org bug #26232. To solve this issue, avoid calling lock_fb_info inside fb_set_suspend, and move it out to where needed (callers of fb_set_suspend must call lock_fb_info before if needed). So far, the only place which needs to call lock_fb_info is store_fbstate, all other places which calls fb_set_suspend are suspend/resume hooks that should not need the lock as they should be run only when processes are already frozen in suspend/resume.

2011-11-11genirq: Add IRQF_RESUME_EARLY and resume such IRQs earlierIan Campbell
commit 9bab0b7fbaceec47d32db51cd9e59c82fb071f5a upstream. This adds a mechanism to resume selected IRQs during syscore_resume instead of dpm_resume_noirq. Under Xen we need to resume IRQs associated with IPIs early enough that the resched IPI is unmasked and we can therefore schedule ourselves out of the stop_machine where the suspend/resume takes place.

2011-11-11md/raid5: fix bug that could result in reads from a failed device.NeilBrown
commit 355840e7a7e56bb2834fd3b0da64da5465f8aeaa upstream. This bug was introduced in 415e72d034c50520ddb7ff79e7d1792c1306f0c9 which was in 2.6.36. There is a small window of time between when a device fails and when it is removed from the array. During this time we might still read from it, but we won't write to it - so it is possible that we could read stale data. We didn't need the test of 'Faulty' before because the test on In_sync is sufficient. Since we started allowing reads from the early part of non-In_sync devices we need a test on Faulty too. This is suitable for any kernel from 2.6.36 onwards, though the patch might need a bit of tweaking in 3.0 and earlier.

commit bee460be8c691c544e84ed678280ace6153104c6 upstream. The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7.

commit ac06697c79bad09e44a8b1d52104014016fb90de upstream. PHY errors relevant for ANI are always tracked by hardware counters, the bits that allow them to pass through the rx filter are independent of that. Enabling PHY errors in the rx filter often creates lots of useless DMA traffic and might be responsible for some of the rx dma stop failure warnings.

commit a8b43c00ef06aec49b9fe0a5bad8a6a320e4d27b upstream. At least some OHCI hardware (such as the MCP89) fails to flag any change in the host status register or the port status registers when receiving a remote wakeup while in D3 state. This results in the controller being resumed but no device state change being noticed, at which point the controller is put back to sleep again. Since there doesn't seem to be any reliable way to identify the state change, just unconditionally resume the hub. It'll be put back to sleep in the near future anyway if there are no active devices attached to it.

commit 6b20fa9aaf0c2f69ee6f9648e20ab2be0206705e upstream. This patch fixes a bug with the handling of REPORT TARGET PORT GROUPS containing a smaller allocation length than the payload requires causing memory writes beyond the end of the buffer. This patch checks for the minimum 4 byte length for the response payload length, and also checks upon each loop of T10_ALUA(su_dev)->tg_pt_gps_list to ensure the Target port group and Target port descriptor list is able to fit into the remaining allocation length. If the response payload exceeds the allocation length length, then rd_len is still increments to indicate to the initiator that the payload has been truncated.
