commit f3aec8f3 upstream. The mvebu-devbus driver had a serious bug, which lead to a 8 bits bus width declared in the Device Tree being considered as a 16 bits bus width when configuring the hardware. This bug in mvebu-devbus driver was compensated by a symetric mistake in the Armada XP DB Device Tree: a 8 bits bus width was declared, even though the hardware actually has a 16 bits bus width connection with the NOR flash. Now that we have fixed the mvebu-devbus driver to behave according to its Device Tree binding, this commit fixes the problematic Device Tree files as well. This bug was introduced in commit b484ff42 ('ARM: mvebu: Add support for NOR flash device on Armada XP-DB board') which was merged in v3.11. Signed-off-by:

commit cf7eb979 upstream. This is another great example of trainwreck engineering: commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support) added support for using EDMA on peripherals which have no direct EDMA event mapping. The code compiles and does not explode in your face, but that's it. 1) Reading an u16 array from an u32 device tree array simply does not work. Even if the function is named "edma_of_read_u32_to_s16_array". It merily calls of_property_read_u16_array. So the resulting 16bit array will have every other entry = 0. 2) The DT entry for the xbar registers related to xbar has length 0x10 instead of the real length: 0xfd0 - 0xf90 = 0x40. Not a real problem as it does not cross a page boundary, but wrong nevertheless. 3) But none of this matters as the mapping never happens: After reading nonsense edma_of_read_u32_to_s16_array() invalidates the first array entry pair, so nobody can ever notice the braindamage by immediate explosion. Seems the QA criteria for this code was solely not to explode when someone adds edma-xbar-event-map entries to the DT. Goal achieved, congratulations! Not really helpful if someone wants to use edma on a device which requires a xbar mapping. Fix the issues by: - annotating the device tree entry with "/bits/ 16" as documented in the of_property_read_u16_array kernel doc - make the size of the xbar register mapping correct - invalidating the end of the array and not the start This convoluted mess wants to be completely rewritten as there is no point to keep the xbar_chan array memory and the iomapping of the xbar regs around forever. Marking the xbar mapped channels as used should be done right there. But that's a different issue and this patch is small enough to make it work and allows a simple backport for stable.

commit 788296b2 upstream. Commit 54397d85 ("ARM: kirkwood: Relocate PCIe device tree nodes") moved the pcie-controller nodes for the Kirkwood SoCs to the mbus bus node. For some reason, two boards were not properly converted and have their pci-controller nodes still in the ocp bus node. As the corresponding SoC pcie-controller does not exist anymore, it is likely that pcie is broken on those boards since above commit. Fix it by moving the pcie related nodes to the correct location.

commit 62376251 upstream. This reverts commit 0bf1457f ("mm: vmscan: do not swap anon pages just because free+file is low") because it introduced a regression in mostly-anonymous workloads, where reclaim would become ineffective and trap every allocating task in direct reclaim. The problem is that there is a runaway feedback loop in the scan balance between file and anon, where the balance tips heavily towards a tiny thrashing file LRU and anonymous pages are no longer being looked at. The commit in question removed the safe guard that would detect such situations and respond with forced anonymous reclaim. This commit was part of a series to fix premature swapping in loads with relatively little cache, and while it made a small difference, the cure is obviously worse than the disease. Revert it.

commit 49e068f0 upstream. The compaction freepage scanner implementation in isolate_freepages() starts by taking the current cc->free_pfn value as the first pfn. In a for loop, it scans from this first pfn to the end of the pageblock, and then subtracts pageblock_nr_pages from the first pfn to obtain the first pfn for the next for loop iteration. This means that when cc->free_pfn starts at offset X rather than being aligned on pageblock boundary, the scanner will start at offset X in all scanned pageblock, ignoring potentially many free pages. Currently this can happen when a) zone's end pfn is not pageblock aligned, or b) through zone->compact_cached_free_pfn with CONFIG_HOLES_IN_ZONE enabled and a hole spanning the beginning of a pageblock This patch fixes the problem by aligning the initial pfn in isolate_freepages() to pageblock boundary. This also permits replacing the end-of-pageblock alignment within the for loop with a simple pageblock_nr_pages increment. Signed-off-by:

commit d5c9fde3 upstream. It is possible for "limit - setpoint + 1" to equal zero, after getting truncated to a 32 bit variable, and resulting in a divide by zero error. Using the fully 64 bit divide functions avoids this problem. It also will cause pos_ratio_polynom() to return the correct value when (setpoint - limit) exceeds 2^32. Also uninline pos_ratio_polynom, at Andrew's request. Signed-off-by:

commit 50c6e282 upstream. Various filesystems don't bother checking for a NULL ACL in posix_acl_equiv_mode, and thus can dereference a NULL pointer when it gets passed one. This usually happens from the NFS server, as the ACL tools never pass a NULL ACL, but instead of one representing the mode bits. Instead of adding boilerplat to all filesystems put this check into one place, which will allow us to remove the check from other filesystems as well later on. Signed-off-by:

commit 3c49aa85 upstream. This reverts commit d2bee8fb. Enabling autosuspend for Intel Bluetooth devices has been shown to not work reliable. It does work for some people with certain combinations of USB host controllers, but for others it puts the device to sleep and it will not wake up for any event. These events can be important ones like HCI Inquiry Complete or HCI Connection Request. The events will arrive as soon as you poke the device with a new command, but that is not something we can do in these cases. Initially there were patches to the xHCI USB controller that fixed this for some people, but not for all. This could be well a problem somewhere in the USB subsystem or in the USB host controllers or just plain a hardware issue somewhere. At this moment we just do not know and the only safe action is to revert this patch. Signed-off-by:

commit 09da1f34 upstream. When we're performing reauthentication (in order to elevate the security level from an unauthenticated key to an authenticated one) we do not need to issue any encryption command once authentication completes. Since the trigger for the encryption HCI command is the ENCRYPT_PEND flag this flag should not be set in this scenario. Instead, the REAUTH_PEND flag takes care of all necessary steps for reauthentication. Signed-off-by:

commit 9eb1fbfa upstream. Commit 1c2e0041 introduced an event handler for the encryption key refresh complete event with the intent of fixing some LE/SMP cases. However, this event is shared with BR/EDR and there we actually want to act only on the auth_complete event (which comes after the key refresh). If we do not do this we may trigger an L2CAP Connect Request too early and cause the remote side to return a security block error. Signed-off-by:

commit c1db30a2 upstream. Some OHCI controllers from ATI/AMD seem to have difficulty with "global" USB suspend, that is, suspending an entire USB bus without setting the suspend feature for each port connected to a device. When we try to resume the child devices, the controller gives timeout errors on the unsuspended ports, requiring resets, and can even cause ohci-hcd to hang; see http://marc.info/?l=linux-usb&m=139514332820398&w=2 and the following messages. This patch fixes the problem by adding a new quirk flag to ohci-hcd. The flag causes the ohci_rh_suspend() routine to suspend each unsuspended, enabled port before suspending the root hub. This effectively converts the "global" suspend to an ordinary root-hub suspend. There is no need to unsuspend these ports when the root hub is resumed, because the child devices will be resumed anyway in the course of a normal system resume ("global" suspend is never used for runtime PM). This patch should be applied to all stable kernels which include commit 0aa2832d (USB: use "global suspend" for system sleep on USB-2 buses) or a backported version thereof. Signed-off-by:

commit d183c819 upstream. Per reference manuals of Freescale P1020 and P2020 SoCs, USB controller present in these SoCs has bit 17 of USBx_CONTROL register marked as Reserved - there is no PHY_CLK_VALID bit there. Testing for this bit in ehci_fsl_setup_phy() behaves differently on two P1020RDB boards available here - on one board test passes and fsl-usb init succeeds, but on other board test fails, causing fsl-usb init to fail. This patch changes ehci_fsl_setup_phy() not to test PHY_CLK_VALID on controller version 1.6 that (per manual) does not have this bit. Signed-off-by:

commit cbfbbabb upstream. The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.
