commit 5dc5616e upstream. Stage 1 translation is controlled by two sets of page tables (TTBR0 and TTBR1) which grow up and down from zero respectively in the ARMv8 translation regime. For the SMMU, we only care about TTBR0 and, in the case of a 48-bit virtual space, we expect to map virtual addresses 0x0 through to 0xffff_ffff_ffff. Given that some masters may be incapable of emitting virtual addresses targetting TTBR1 (e.g. because they sit on a 48-bit bus), the SMMU architecture allows bit 47 to be sign-extended, halving the virtual range of TTBR0 but allowing TTBR1 to be used. This is controlled by the SEP field in TTBCR2. The SMMU driver incorrectly enables this sign-extension feature, which causes problems when userspace addresses are programmed into a master device with the SMMU expecting to map the incoming transactions via TTBR0; if the top bit of address is set, we will instead get a translation fault since TTBR1 walks are disabled in the TTBCR. This patch fixes the issue by disabling sign-extension of a fixed virtual address bit and instead basing the behaviour on the upstream bus size: the incoming address is zero extended unless the upstream bus is only 49 bits wide, in which case bit 48 is used as the sign bit and is replicated to the upper bits.

commit 1bf1b431 upstream. This patch fixes a bug in put_pasid_state_wait that appeared in kernel 4.0 The bug is that pasid_state->count wasn't decremented before entering the wait_event. Thus, the condition in wait_event will never be true. The fix is to decrement (atomically) the pasid_state->count before the wait_event. Signed-off-by:

commit 820f9f14 upstream. This is needed to support lazily umounting locked mounts. Because the entire unmounted subtree needs to stay together until there are no users with references to any part of the subtree. To support this guarantee that the fs_pin m_list and s_list nodes are initialized by initializing them in init_fs_pin allowing for the possibility that pin_insert_group does not touch them. Further use hlist_del_init in pin_remove so that there is a hlist_unhashed test before the list we attempt to update the previous list item. Signed-off-by:

commit cd4a4017 upstream. The only users of collect_mounts are in audit_tree.c In audit_trim_trees and audit_add_tree_rule the path passed into collect_mounts is generated from kern_path passed an audit_tree pathname which is guaranteed to be an absolute path. In those cases collect_mounts is obviously intended to work on mounted paths and if a race results in paths that are unmounted when collect_mounts it is reasonable to fail early. The paths passed into audit_tag_tree don't have the absolute path check. But are used to play with fsnotify and otherwise interact with the audit_trees, so again operating only on mounted paths appears reasonable. Avoid having to worry about what happens when we try and audit unmounted filesystems by restricting collect_mounts to mounts that appear in the mount tree. Signed-off-by:

commit 1d0a0b2f upstream. ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6 For physical addresses, since the address may exceed 32-bit address range after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT and ACPI_FORMAT_UINT64() instead of ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT(). This patch also removes above replaced macros as there are no users. This is a preparation to switch acpi_physical_address to 64-bit on 32-bit kernel builds.

commit 6d3fd3cc upstream. ACPICA commit 154f6d074dd38d6ebc0467ad454454e6c5c9ecdf There are code pieces converting pointers using "(acpi_physical_address) x" or "ACPI_CAST_PTR (t, x)" formats, this patch cleans up them. Known issues: 1. Cleanup of "(ACPI_PHYSICAL_ADDRRESS) x" for a table field For the conversions around the table fields, it is better to fix it with alignment also fixed. So this patch doesn't modify such code. There should be no functional problem by leaving them unchanged. Link: https://github.com/acpica/acpica/commit/154f6d07Signed-off-by:

commit bc26d4d0 upstream. A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND) on /dev/sequencer with TMR_ECHO midi event. In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning. Compile tested only. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

commit bad4371d upstream. f9fd54f2 ("mmc: sh_mmcif: Use msecs_to_jiffies() for host->timeout") changed the timeout value from 1000 jiffies to 1s. In the case where HZ is 1000 the values are the same. However, for smaller HZ values the timeout is now smaller, 1s instead of 10s in the case of HZ=100. Since the timeout occurs in spite of a normal data transfer a timeout of 10s seems more appropriate. This restores the previous timeout in the case where HZ=100 and results in an increase over the previous timeout for larger values of HZ.

commit c5272a28 upstream. Way back, when the world was a simpler place and there was no war, no evil, and no kernel bugs, there was just a single pinctrl lock. That was how the world was when (57291ce2 pinctrl: core device tree mapping table parsing support) was written. In that case, there were instances where the pinctrl mutex was already held when pinctrl_register_map() was called, hence a "locked" parameter was passed to the function to indicate that the mutex was already locked (so we shouldn't lock it again). A few years ago in (42fed7ba pinctrl: move subsystem mutex to pinctrl_dev struct), we switched to a separate pinctrl_maps_mutex. ...but (oops) we forgot to re-think about the whole "locked" parameter for pinctrl_register_map(). Basically the "locked" parameter appears to still refer to whether the bigger pinctrl_dev mutex is locked, but we're using it to skip locks of our (now separate) pinctrl_maps_mutex. That's kind of a bad thing(TM). Probably nobody noticed because most of the calls to pinctrl_register_map happen at boot time and we've got synchronous device probing. ...and even cases where we're asynchronous don't end up actually hitting the race too often. ...but after banging my head against the wall for a bug that reproduced 1 out of 1000 reboots and lots of looking through kgdb, I finally noticed this. Anyway, we can now safely remove the "locked" parameter and go back to a war-free, evil-free, and kernel-bug-free world.

commit 3916e3fd upstream. Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz) as a BTO option, both versions used dual channel LVDS even though the smaller one would have fit into a single channel. Notes: Bug report showing that the MacBookPro8,2 with 1440x900 uses dual channel LVDS (this lead to it being hardcoded in intel_lvds.c by Daniel Vetter with commit 618563e3): https://bugzilla.kernel.org/show_bug.cgi?id=42842 If i915.lvds_channel_mode=2 is missing even though the machine needs it, every other vertical line is white and consequently, only the left half of the screen is visible (verified by myself on a MacBookPro9,1). Forum posting concerning a MacBookPro6,2 with 1440x900, author is using i915.lvds_channel_mode=2 on the kernel command line, proving that the machine uses dual channels: https://bbs.archlinux.org/viewtopic.php?id=185770 Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all MacBook Pro "A1286" models, and that model number encompasses the MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's driven with dual channel LVDS: http://www.ebay.com/itm/-/400690878560 http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286 http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones with i915 graphics and dual channel LVDS, so that list should be complete. And the 8,2 is already in intel_lvds.c. Possible motivation to use dual channel LVDS even on the 1440x900 models: Reduce the number of different parts, i.e. use identical logic boards and display cabling on both versions and the only differing component is the panel.

commit fdb68e09 upstream. Since commit 844b03f2 we make sure that after vblank irq off, we return the last valid (vblank count, vblank timestamp) pair to clients, e.g., during modesets, which is good. An overlooked side effect of that commit for kms drivers without support for precise vblank timestamping is that at vblank irq enable, when we update the vblank counter from the hw counter, we can't update the corresponding vblank timestamp, so now we have a totally mismatched timestamp for the new count to confuse clients. Restore old client visible behaviour from before Linux 3.17, but zero out the timestamp at vblank counter update (instead of disable as in original implementation) if we can't generate a meaningful timestamp immediately for the new vblank counter. This will fix this regression, so callers know they need to retry again later if they need a valid timestamp, but at the same time preserves the improvements made in the commit mentioned above.

commit 102bcb6e upstream. If we use a combination of VMODE and I2C4 for retention modes, eventually the off idle power consumption will creep up by about 23mW, even during off mode with I2C4 always staying enabled. Turns out this is because of erratum i531 "Extra Power Consumed When Repeated Start Operation Mode Is Enabled on I2C Interface Dedicated for Smart Reflex (I2C4)" as pointed out by Nishanth Menon <nm@ti.com>. Let's fix the issue by adding i2c_cfg_clear_mask for the bits to clear when initializing the I2C4 adapter so we can clear SREN bit that drives the I2C4 lines low otherwise when there is no traffic.
