commit fdf35a6b upstream. I noticed that the VT switch doesn't work any longer with a Dell laptop with 1366x768 eDP when the machine is connected with a DP monitor. It behaves as if VT were switched, but the graphics remain frozen. Actually the keyboard works, so I could switch back to VT7 again. I tried to track down the problem, and encountered a long story until we reach to this error: - The machine is booted with video=1366x768 option (the distro installer seems to add it as default). - Recently, drm_helper_probe_single_connector_modes() deals with cmdline modes, and it tries to create a new mode when no matching mode is found. - The drm_mode_create_from_cmdline_mode() creates a mode based on either CVT of GFT according to the given cmdline mode; in our case, it's 1366x768. - Since both CVT and GFT can't express the width 1366 due to alignment, the resultant mode becomes 1368x768, slightly larger than the given size. - Later on, the atomic commit is performed, and in drm_atomic_check_only(), the size of each plane is checked. - The size check of 1366x768 fails due to the above, and eventually the whole VT switch fails. Back in the history, we've had a manual fix-up of 1368x768 in various places via c09dedb7 ("drm/edid: Add a workaround for 1366x768 HD panel"), but they have been all in drm_edid.c at probing the modes from EDID. For addressing the problem above, we need a similar hack to the mode newly created from cmdline, manually adjusting the width when the expected size is 1366 while we get 1368 instead.

commit 7d9e8f71 upstream. Generally, taking an unexpected exception should be a fatal event, and bad_mode is intended to cater for this. However, it should be possible to contain unexpected synchronous exceptions from EL0 without bringing the kernel down, by sending a SIGILL to the task. We tried to apply this approach in commit 9955ac47 ("arm64: don't kill the kernel on a bad esr from el0"), by sending a signal for any bad_mode call resulting from an EL0 exception. However, this also applies to other unexpected exceptions, such as SError and FIQ. The entry paths for these exceptions branch to bad_mode without configuring the link register, and have no kernel_exit. Thus, if we take one of these exceptions from EL0, bad_mode will eventually return to the original user link register value. This patch fixes this by introducing a new bad_el0_sync handler to cater for the recoverable case, and restoring bad_mode to its original state, whereby it calls panic() and never returns. The recoverable case branches to bad_el0_sync with a bl, and returns to userspace via the usual ret_to_user mechanism. Signed-off-by:

commit 90f92c63 upstream. The following patch was sketched by Russell in response to my crashes on the PB11MPCore after the patch for software-based priviledged no access support for ARMv8.1. See this thread: http://marc.info/?l=linux-arm-kernel&m=144051749807214&w=2 I am unsure what is going on, I suspect everyone involved in the discussion is. I just want to repost this to get the discussion restarted, as I still have to apply this patch with every kernel iteration to get my PB11MPCore Realview running. Testing by Neil Armstrong on the Oxnas NAS has revealed that this bug exist also on that widely deployed hardware, so we are probably currently regressing all ARM11MPCore systems.

commit 43849785 upstream. Read access to the SPI flash are broken on da850-evm, i.e. the data read is not what is actually programmed on the flash. According to the datasheet for the M25P64 part present on the da850-evm, if the SPI frequency is higher than 20MHz then the READ command is not usable anymore and only the FAST_READ command can be used to read data. This commit specifies in the DTS that we should use FAST_READ command instead of the READ command. Tested-by:

commit ddc37832 upstream. On APQ8060, the kernel crashes in arch_hw_breakpoint_init, taking an undefined instruction trap within write_wb_reg. This is because Scorpion CPUs erroneously appear to set DBGPRSR.SPD when WFI is issued, even if the core is not powered down. When DBGPRSR.SPD is set, breakpoint and watchpoint registers are treated as undefined. It's possible to trigger similar crashes later on from userspace, by requesting the kernel to install a breakpoint or watchpoint, as we can go idle at any point between the reset of the debug registers and their later use. This has always been the case. Given that this has always been broken, no-one has complained until now, and there is no clear workaround, disable hardware breakpoints and watchpoints on Scorpion to avoid these issues.

commit ce1ca7d2 upstream. In rdma_read_chunk_frmr() when ib_post_send() fails, the error code path invokes ib_dma_unmap_sg() to unmap the sg list. It then invokes svc_rdma_put_frmr() which in turn tries to unmap the same sg list through ib_dma_unmap_sg() again. This second unmap is invalid and could lead to problems when the iova being unmapped is subsequently reused. Remove the call to unmap in rdma_read_chunk_frmr() and let svc_rdma_put_frmr() handle it.

commit 1cb51a15 upstream. When replaying the journal it can happen that a journal entry points to a garbage collected node. This is the case when a power-cut occurred between a garbage collect run and a commit. In such a case nodes have to be read using the failable read functions to detect whether the found node matches what we expect. One corner case was forgotten, when the journal contains an entry to remove an inode all xattrs have to be removed too. UBIFS models xattr like directory entries, so the TNC code iterates over all xattrs of the inode and removes them too. This code re-uses the functions for walking directories and calls ubifs_tnc_next_ent(). ubifs_tnc_next_ent() expects to be used only after the journal and aborts when a node does not match the expected result. This behavior can render an UBIFS volume unmountable after a power-cut when xattrs are used. Fix this issue by using failable read functions in ubifs_tnc_next_ent() too when replaying the journal.

commit 51ebfc92 upstream. A PCI-to-PCIe bridge (a "reverse bridge") has a PCI or PCI-X primary interface and a PCI Express secondary interface. The PCIe interface is a Downstream Port that originates a Link. See the "PCI Express to PCI/PCI-X Bridge Specification", rev 1.0, sections 1.2 and A.6. The bug report below involves a PCI-to-PCIe bridge and a PCIe switch below the bridge: 00:1e.0 Intel 82801 PCI Bridge to [bus 01-0a] 01:00.0 Pericom PI7C9X111SL PCIe-to-PCI Reversible Bridge to [bus 02-0a] 02:00.0 Pericom Device 8608 [PCIe Upstream Port] to [bus 03-0a] 03:01.0 Pericom Device 8608 [PCIe Downstream Port] to [bus 0a] 01:00.0 is configured as a PCI-to-PCIe bridge (despite the name printed by lspci). As we traverse a PCIe hierarchy, device connections alternate between PCIe Links and internal Switch logic. Previously we did not recognize that 01:00.0 had a secondary link, so we thought the 02:00.0 Upstream Port *did* have a secondary link. In fact, it's the other way around: 01:00.0 has a secondary link, and 02:00.0 has internal Switch logic on its secondary side. When we thought 02:00.0 had a secondary link, the pci_scan_slot() -> only_one_child() path assumed 02:00.0 could have only one child, so 03:00.0 was the only possible downstream device. But 03:00.0 doesn't exist, so we didn't look for any other devices on bus 03. Booting with "pci=pcie_scan_all" is a workaround, but we don't want users to have to do that. Recognize that PCI-to-PCIe bridges originate links on their secondary interfaces.

commit 78794d18 upstream. Context expiry times are in units of seconds since boot, not unix time. The use of get_seconds() here therefore sets the expiry time decades in the future. This prevents timely freeing of contexts destroyed by client RPC_GSS_PROC_DESTROY requests. We'd still free them eventually (when the module is unloaded or the container shut down), but a lot of contexts could pile up before then.

commit 0b59970e upstream. Remove the warning print of "can't use of GFP_NOIO" to avoid prints in each QP creation when devices aren't supporting IB_QP_CREATE_USE_GFP_NOIO. This print become more annoying when the IPoIB interface is configured to work in connected mode. Fixes: 09b93088 ('IB: Add a QP creation flag to use GFP_NOIO allocations') Signed-off-by:
