commit 7a98948f upstream. The vblank waits in intel_tv_detect_type() are timing out for some reason. This is a regression caused removing seemingly useless vblank waits from the modeset seqeuence in: commit 56ef52ca Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Thu May 8 19:23:15 2014 +0300 drm/i915: Kill vblank waits after pipe enable on gmch platforms So it turns out they weren't all entirely useless. Apparently the pipe has to go through one full frame before we enable the TV port. Add a vblank wait to intel_enable_tv() to make sure that happens. Another approach was attempted by placing the vblank wait just after enabling the port. The theory behind that attempt was that we need to let the port stay enabled for one full frame before disabling it again during load detection. But that didn't work, and we definitely must have the vblank wait before enabling the port. Cc: Alan Bartlett <ajb@elrepo.org> Tested-by:

commit bbe1c274 upstream. The __init annotations for the DMI callback functions are wrong as this code can be called even after the module has been initialized, e.g. like this: # echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove # modprobe i915 # echo 1 > /sys/bus/pci/rescan The first command will remove the PCI device from the kernel's device list so the second command won't see it right away. But as it registers a PCI driver it'll see it on the third command. If the system happens to match one of the DMI table entries we'll try to call a function in long released memory and generate an Oops, at best. Fix this by removing the bogus annotation. Modpost should have caught that one but it ignores section reference mismatches from the .rodata section. :/ Fixes: 25e341cf ("drm/i915: quirk away broken OpRegion VBT") Fixes: 8ca4013d ("CHROMIUM: i915: Add DMI override to skip CRT...")

commit e15693ef upstream. cfq_group_service_tree_add() is applying new_weight at the beginning of the function via cfq_update_group_weight(). This actually allows weight to change between adding it to and subtracting it from children_weight, and triggers WARN_ON_ONCE() in cfq_group_service_tree_del(), or even causes oops by divide error during vfr calculation in cfq_group_service_tree_add(). The detailed scenario is as follows: 1. Create blkio cgroups X and Y as a child of X. Set X's weight to 500 and perform some I/O to apply new_weight. This X's I/O completes before starting Y's I/O. 2. Y starts I/O and cfq_group_service_tree_add() is called with Y. 3. cfq_group_service_tree_add() walks up the tree during children_weight calculation and adds parent X's weight (500) to children_weight of root. children_weight becomes 500. 4. Set X's weight to 1000. 5. X starts I/O and cfq_group_service_tree_add() is called with X. 6. cfq_group_service_tree_add() applies its new_weight (1000). 7. I/O of Y completes and cfq_group_service_tree_del() is called with Y. 8. I/O of X completes and cfq_group_service_tree_del() is called with X. 9. cfq_group_service_tree_del() subtracts X's weight (1000) from children_weight of root. children_weight becomes -500. This triggers WARN_ON_ONCE(). 10. Set X's weight to 500. 11. X starts I/O and cfq_group_service_tree_add() is called with X. 12. cfq_group_service_tree_add() applies its new_weight (500) and adds it to children_weight of root. children_weight becomes 0. Calcularion of vfr triggers oops by divide error. weight should be updated right before adding it to children_weight. Reported-by:

commit 7a9744cb upstream. When a driver is set up without the jack detection explicitly (either by passing a model option or via a specific fixup), the pin powermap of IDT/STAC codecs is set up wrongly, resulting in the silence output. It's because of a logic failure in stac_init_power_map(). It tries to avoid creating a callback for the pins that have other auto-hp and auto-mic callbacks, but the check is done in a wrong way at a wrong time. The stac_init_power_map() should be called after creating other jack detection ctls, and the jack callback should be created only for jack-detectable widgets. This patch fixes the check in stac_init_power_map() and its callee at the right place, after snd_hda_gen_build_controls(). Reported-by:

commit 4ce97dbf upstream. Epoll on trace_pipe can sometimes hang in a weird case. If the ring buffer is empty when we set waiters_pending but an event shows up exactly at that moment we can miss being woken up by the ring buffers irq work. Since ring_buffer_empty() is inherently racey we will sometimes think that the buffer is not empty. So we don't get woken up and we don't think there are any events even though there were some ready when we added the watch, which makes us hang. This patch fixes this by making sure that we are actually on the wait list before we set waiters_pending, and add a memory barrier to make sure ring_buffer_empty() is going to be correct.

commit 6721f28a upstream. There is a race condition in at91_do_twi_xfer when signals arrive. If a signal is recieved while waiting for a transfer to complete wait_for_completion_interruptible_timeout() will return -ERESTARTSYS. This is not handled correctly resulting in interrupts still being enabled and a transfer being in flight when we return. Symptoms include a range of oopses and bus lockups. Oopses can happen when the transfer completes because the interrupt handler will corrupt the stack. If a new transfer is started before the interrupt fires the controller will start a new transfer in the middle of the old one, resulting in confused slaves and a locked bus. To avoid this, use wait_for_completion_io_timeout instead so that we don't have to deal with gracefully shutting down the transfer and disabling the interrupts. Signed-off-by:

commit 75b81f33 upstream. The driver was not bound checking the received length byte to ensure it was within the the buffer size that is allocated for SMBus blocks. This resulted in buffer overflows whenever an invalid length byte was received. It also failed to ensure the length byte was not zero. If it received zero, it would end up in an infinite loop as the at91_twi_read_next_byte function returned immediately without allowing RHR to be read to clear the RXRDY interrupt. Tested agaisnt a SMBus compliant battery. Signed-off-by:

commit 0ce4bc1d upstream. The "clock-frequency" DT property is listed as optional, However, the current code stores the return value of of_property_read_u32 in the return code of mv64xxx_of_config, but then forgets to clear it after setting the default value of "clock-frequency". It is then passed out to the main probe function, resulting in a probe failure when "clock-frequency" is missing. This patch checks and then throws away the return value of of_property_read_u32, instead of storing it and having to clear it afterwards. This issue was discovered after the property was removed from all sunxi DTs. Fixes: 4c730a06 ("i2c: mv64xxx: Set bus frequency to 100kHz if clock-frequency is not provided") Signed-off-by:

commit 05e0127f upstream. The architecture specifies that when the processor wakes up from a WFE or WFI instruction, the instruction is considered complete, however we currrently return to EL1 (or EL0) at the WFI/WFE instruction itself. While most guests may not be affected by this because their local exception handler performs an exception returning setting the event bit or with an interrupt pending, some guests like UEFI will get wedged due this little mishap. Simply skip the instruction when we have completed the emulation. Acked-by:

commit 3d8afe30 upstream. The arm64 interrupt migration code on cpu offline calls irqchip.irq_set_affinity() with the argument force=true. Originally this argument had no effect because it was not used by any interrupt chip driver and there was no semantics defined. This changed with commit 01f8fa4f ("genirq: Allow forcing cpu affinity of interrupts") which made the force argument useful to route interrupts to not yet online cpus without checking the target cpu against the cpu online mask. The following commit ffde1de6 ("irqchip: gic: Support forced affinity setting") implemented this for the GIC interrupt controller. As a consequence the cpu offline irq migration fails if CPU0 is offlined, because CPU0 is still set in the affinity mask and the validation against cpu online mask is skipped to the force argument being true. The following first_cpu(mask) selection always selects CPU0 as the target. Commit 601c9421("arm64: use cpu_online_mask when using forced irq_set_affinity") intended to fix the above mentioned issue but introduced another issue where affinity can be migrated to a wrong CPU due to unconditional copy of cpu_online_mask. As with for arm, solve the issue by calling irq_set_affinity() with force=false from the CPU offline irq migration code so the GIC driver validates the affinity mask against CPU online mask and therefore removes CPU0 from the possible target candidates. Also revert the changes done in the commit 601c9421 as it's no longer needed. Tested on Juno platform. Fixes: 601c9421("arm64: use cpu_online_mask when using forced irq_set_affinity") Signed-off-by:

This patch updates the flushing code so that we: (1) Unconditionally zero the tpidr_el0 register (since this is fully context switched for native tasks and zeroed for compat tasks) (2) Zero the tp_value state in thread_info before clearing the tpidrr0_el0 register for compat tasks (since this is only writable by the set_tls compat syscall and therefore not fully switched). A missing compiler barrier is also added to the compat set_tls syscall. Acked-by:

commit d856f32a upstream. As reported by Dan Aloni, commit f8567a38 ("aio: fix aio request leak when events are reaped by userspace") introduces a regression when user code attempts to perform io_submit() with more events than are available in the ring buffer. Reverting that commit would reintroduce a regression when user space event reaping is used. Fixing this bug is a bit more involved than the previous attempts to fix this regression. Since we do not have a single point at which we can count events as being reaped by user space and io_getevents(), we have to track event completion by looking at the number of events left in the event ring. So long as there are as many events in the ring buffer as there have been completion events generate, we cannot call put_reqs_available(). The code to check for this is now placed in refill_reqs_available(). A test program from Dan and modified by me for verifying this bug is available at http://www.kvack.org/~bcrl/20140824-aio_bug.c .

commit a9ecdc0f upstream. In case the Device Tree blob passed by the boot agent supplies both an 'interrupts-extended' and an 'interrupts' property in order to allow for older kernels to be usable, prefer the new-style 'interrupts-extended' property which conveys a lot more information. This allows us to have bootloaders willingly maintaining backwards compatibility with older kernels without entirely deprecating the 'interrupts' property. Update the bindings documentation to describe a situation where both the 'interrupts-extended' and the 'interrupts' property are present, and which one takes precedence over the other. Acked-by:

Withtout this, ring initialization fails reliabily during resume with [drm:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001 head ffffff8804 tail 00000000 start 000e4000 This is not a complete fix, but it is verified to make the ring initialization failures during resume much less likely. We were not able to root-cause this bug (likely HW-specific to Gen4 chips) yet. This is therefore used as a ducttape before problem is fully understood and proper fix created, so that people don't suffer from completely unusable systems in the meantime.
