commit e7e034e1 upstream. The RTC control register should be enabled in the process of initializing. Without this patch, I failed to enable RTC in Hisilicon Hi3620 SoC. The register mapping section in RTC is always read as zero. So I doubt that ST guys may already enable this register in bootloader. So they won't meet this issue. Signed-off-by:

commit bc5bd37c upstream. Pavel Roskin reported that DRM_IOCTL_MODE_GETCONNECTOR was overwritting the 4 bytes beyond the end of its structure with a 32-bit userspace running on a 64-bit kernel. This is due to the padding gcc inserts as the drm_mode_get_connector struct includes a u64 and its size is not a natural multiple of u64s. 64-bit kernel: sizeof(drm_mode_get_connector)=80, alignof=8 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 32-bit userspace: sizeof(drm_mode_get_connector)=76, alignof=4 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 Fortuituously we can insert explicit padding to the tail of our structures without breaking ABI.

commit cac6a5ae upstream. ACPI has _BCM and _BQC methods to set and query the backlight brightness, respectively. The ACPI opregion has variables BCLP and CBLV to hold the requested and current backlight brightness, respectively. The BCLP variable has range 0..255 while the others have range 0..100. This means the _BCM method has to scale the brightness for BCLP, and the gfx driver has to scale the requested value back for CBLV. If the _BQC method uses the CBLV variable (apparently some implementations do, some don't) for current backlight level reporting, there's room for rounding errors. Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values that were passed to _BCM, presuming the _BCM simply uses bclp = (in * 255) / 100 for scaling to BCLP.

commit f7929f34 upstream. Hello, got another card with "too bright" problem: Sapphire Radeon VE 7000 DDR (VGA+S-Video) lspci -vnn: 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV100 QY [Radeon 7000/VE] [1002:5159] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Sapphire Radeon VE 7000 DDR [174b:7c28] The patch below fixes the problem for this card. But I don't like the blacklist, couldn't some heuristic be used instead? The interesting thing is that the manufacturer is the same as the other card needing the same quirk. I wonder how many different types are broken this way. The "wrong" ps2_pdac_adj value that comes from BIOS on this card is 0x300. ==================== drm/radeon: Add primary dac adj quirk for Sapphire Radeon VE 7000 DDR Values from BIOS are wrong, causing too bright colors.

commit dc652f90 upstream. Backlight cleanup in the eDP connector destroy callback caused the backlight device to be removed on some systems that first initialized LVDS and then attempted to initialize eDP. Prevent multiple backlight initializations, and ensure backlight cleanup is only done once by moving it to modeset cleanup. A small wrinkle is the introduced asymmetry in backlight setup/cleanup. This could be solved by adding refcounting, but it seems overkill considering that there should only ever be one backlight device.

commit 7bd90909 upstream. Following the documentation of the Legacy Backlight Brightness (LBB) Register in the configuration space of some Intel PCI graphics adapters, setting the LBB register with the value 0x0 causes the backlight to be turned off, and 0xFF causes the backlight to be set to 100% intensity (http://download.intel.com/embedded/processors/Whitepaper/324567.pdf). The Acer Aspire 5734Z, however, turns the backlight off at 0xFF and sets it to maximum intensity at 0. In consequence, the screen of this systems becomes dark at an early boot stage which makes it unusable. The same inversion applies to the BLC_PWM_CTL I915 register. This problem was introduced in kernel version 2.6.38 when the PCI device of this system was first supported by the i915 KMS module. This patch adds a parameter to the i915 module to enable inversion of the brightness variable (i915.invert_brightness). Signed-off-by:

commit e7d841ca upstream. Before queuing the flip but crucially after attaching the unpin-work to the crtc, we continue to setup the unpin-work. However, should the hardware fire early, we see the connected unpin-work and queue the task. The task then promptly runs and unpins the fb before we finish taking the required references or even pinning it... Havoc. To close the race, we use the flip-pending atomic to indicate when the flip is finally setup and enqueued. So during the flip-done processing, we can check more accurately whether the flip was expected. v2: Add the appropriate mb() to ensure that the writes to the page-flip worker are complete prior to marking it active and emitting the MI_FLIP. On the read side, the mb should be enforced by the spinlocks. Signed-off-by:

commit 3a2d63f8 upstream. There are two problems with shutdown in the NBD driver. 1: Receiving the NBD_DISCONNECT ioctl does not sync the filesystem. This patch adds the sync operation into __nbd_ioctl()'s NBD_DISCONNECT handler. This is useful because BLKFLSBUF is restricted to processes that have CAP_SYS_ADMIN, and the NBD client may not possess it (fsync of the block device does not sync the filesystem, either). 2: Once we clear the socket we have no guarantee that later reads will come from the same backing storage. The patch adds calls to kill_bdev() in __nbd_ioctl()'s socket clearing code so the page cache is cleaned, lest reads that hit on the page cache will return stale data from the previously-accessible disk. Example: # qemu-nbd -r -c/dev/nbd0 /dev/sr0 # file -s /dev/nbd0 /dev/stdin: # UDF filesystem data (version 1.5) etc. # qemu-nbd -d /dev/nbd0 # qemu-nbd -r -c/dev/nbd0 /dev/sda # file -s /dev/nbd0 /dev/stdin: # UDF filesystem data (version 1.5) etc. While /dev/sda has: # file -s /dev/sda /dev/sda: x86 boot sector; etc. Signed-off-by:

commit f8b84043 upstream. This patch reworks the UEFI anti-bricking code, including an effective reversion of cc5a080c and 31ff2f20. It turns out that calling QueryVariableInfo() from boot services results in some firmware implementations jumping to physical addresses even after entering virtual mode, so until we have 1:1 mappings for UEFI runtime space this isn't going to work so well. Reverting these gets us back to the situation where we'd refuse to create variables on some systems because they classify deleted variables as "used" until the firmware triggers a garbage collection run, which they won't do until they reach a lower threshold. This results in it being impossible to install a bootloader, which is unhelpful. Feedback from Samsung indicates that the firmware doesn't need more than 5KB of storage space for its own purposes, so that seems like a reasonable threshold. However, there's still no guarantee that a platform will attempt garbage collection merely because it drops below this threshold. It seems that this is often only triggered if an attempt to write generates a genuine EFI_OUT_OF_RESOURCES error. We can force that by attempting to create a variable larger than the remaining space. This should fail, but if it somehow succeeds we can then immediately delete it. I've tested this on the UEFI machines I have available, but I don't have a Samsung and so can't verify that it avoids the bricking problem. Signed-off-by:

commit a93bc0c6 upstream. [Problem] efi_pstore creates sysfs entries, which enable users to access to NVRAM, in a write callback. If a kernel panic happens in an interrupt context, it may fail because it could sleep due to dynamic memory allocations during creating sysfs entries. [Patch Description] This patch removes sysfs operations from a write callback by introducing a workqueue updating sysfs entries which is scheduled after the write callback is called. Also, the workqueue is kicked in a just oops case. A system will go down in other cases such as panic, clean shutdown and emergency restart. And we don't need to create sysfs entries because there is no chance for users to access to them. efi_pstore will be robust against a kernel panic in an interrupt context with this patch.
