commit 78fd6dcf upstream. We currently have the SCTLR_EL2.A bit set, trapping unaligned accesses at EL2, but we're not really prepared to deal with it. So far, this has been unnoticed, until GCC 7 started emitting those (in particular 64bit writes on a 32bit boundary). Since the rest of the kernel is pretty happy about that, let's follow its example and set SCTLR_EL2.A to zero. Modern CPUs don't really care. Reported-by:

commit d68c1f7f upstream. __do_hyp_init has the rather bad habit of ignoring RES1 bits and writing them back as zero. On a v8.0-8.2 CPU, this doesn't do anything bad, but may end-up being pretty nasty on future revisions of the architecture. Let's preserve those bits so that we don't have to fix this later on.

commit d4912215 upstream.

It can't be reproduced easily. Commit 0b6ac343 (KVM: nVMX: Correct handling of exception injection) mentioned that "KVM wants to inject page-faults which it got to the guest. This function assumes it is called with the exit reason in vmcs02 being a #PF exception". Commit e011c663 (KVM: nVMX: Check all exceptions for intercept during delivery to L2) allows to check all exceptions for intercept during delivery to L2. However, there is no guarantee the exit reason is exception currently, when there is an external interrupt occurred on host, maybe a time interrupt for host which should not be injected to guest, and somewhere queues an exception, then the function nested_vmx_check_exception() will be called and the vmexit emulation codes will try to emulate the "Acknowledge interrupt on exit" behavior, the warning is triggered. Reusing the exit reason from the L2->L0 vmexit is wrong in this case, the reason must always be EXCEPTION_NMI when injecting an exception into L1 as a nested vmexit.

commit 282bf1fe upstream. These devices feature multiple interfaces/endpoints: a legacy BIOS/boot interface (endpoint 0x81), as well as 2 corsair-specific keyboard interfaces (endpoint 0x82, 0x83 IN/0x03 OUT) and an RGB LED control interface (endpoint 0x84 IN/0x04 OUT) Because the extra 3 interfaces are not of subclass USB_INTERFACE_SUBCLASS_BOOT, HID_QUIRK_NOGET is not automatically set on them and a 10s timeout per-endpoint (30s per device) occurs initialising reports on boot. We configure HID_QUIRK_NO_INIT_REPORTS for these devices. Additionally the left-side G1-G18 macro keys on the K95RGB generate output on the un-opened 0x82/0x83 endpoints which causes the keyboard to stop responding waiting for this event to be collected. We enable HID_QUIRK_ALWAYS_POLL to prevent this situation from occurring. Signed-off-by:

commit c14022bf upstream. The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID 1a2c:0027 does not seem to be handling the reports initialization very well. This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel when connected, and a delay before its initialization. It can also cause the hang the system. This patch adds the quirk for this device, which causes the delay to disappear. It is named as "USB Keykoard2" because the "USB Keykoard" already exists. Signed-off-by:

commit b6ad9a26 upstream. The WiiU adapter from Mayflash (see http://www.mayflash.com/Products/NINTENDOWiiU/W009.html) is not working correctly. The "XInput" mode works fine, the controller is recognized as a xbox controller. But it is only possible to connect one controller with this method. In "DInput" mode the device is recognized as some kind of mouse input but no joystick is created. This commit will change this behavior with HID_QUIRK_MULTI_INPUT to split the device into 4 input devices so that it will also create joysticks in /dev/input/js*. Signed-off-by:

commit d6ea2f88 upstream. The raphnet.net 4nes4snes and 2nes2snes multi-joystick adapters use a single HID report descriptor with one report ID per controller. This has the effect that the inputs of otherwise independent game controllers get packed in one large joystick device. With this patch each controller gets its own /dev/input/jsX device, which is more natural and less confusing than having all inputs going to the same place. Signed-off-by:

commit 70b69cfb upstream. Based on a patch from: Nikolai Kondrashov <Nikolai.Kondrashov@redhat.com> Most of the tablets handled by hid-uclogic already use MULTI_INPUT. For the ones which are not quirked in usbhid/hidquirks, they have a custom report descriptor which contains only one report per HID interface. For those tablets HID_QUIRK_MULTI_INPUT is transparent. According to https://github.com/DIGImend/tablets, the only problematic tablet currently handled by hid-uclogic is the TWHA60 v3. This tablet presents different report descriptors from the ones currently quirked. This is not a problem per se, given that this tablet is not supported currently in this version (it needs the same command as a Huion to start forwarding events). Reviewed-by:

commit ba4a648f upstream. In commit 8c272261 ("powerpc/numa: Enable USE_PERCPU_NUMA_NODE_ID"), we switched to the generic implementation of cpu_to_node(), which uses a percpu variable to hold the NUMA node for each CPU. Unfortunately we neglected to notice that we use cpu_to_node() in the allocation of our percpu areas, leading to a chicken and egg problem. In practice what happens is when we are setting up the percpu areas, cpu_to_node() reports that all CPUs are on node 0, so we allocate all percpu areas on node 0. This is visible in the dmesg output, as all pcpu allocs being in group 0: pcpu-alloc: [0] 00 01 02 03 [0] 04 05 06 07 pcpu-alloc: [0] 08 09 10 11 [0] 12 13 14 15 pcpu-alloc: [0] 16 17 18 19 [0] 20 21 22 23 pcpu-alloc: [0] 24 25 26 27 [0] 28 29 30 31 pcpu-alloc: [0] 32 33 34 35 [0] 36 37 38 39 pcpu-alloc: [0] 40 41 42 43 [0] 44 45 46 47 To fix it we need an early_cpu_to_node() which can run prior to percpu being setup. We already have the numa_cpu_lookup_table we can use, so just plumb it in. With the patch dmesg output shows two groups, 0 and 1: pcpu-alloc: [0] 00 01 02 03 [0] 04 05 06 07 pcpu-alloc: [0] 08 09 10 11 [0] 12 13 14 15 pcpu-alloc: [0] 16 17 18 19 [0] 20 21 22 23 pcpu-alloc: [1] 24 25 26 27 [1] 28 29 30 31 pcpu-alloc: [1] 32 33 34 35 [1] 36 37 38 39 pcpu-alloc: [1] 40 41 42 43 [1] 44 45 46 47 We can also check the data_offset in the paca of various CPUs, with the fix we see: CPU 0: data_offset = 0x0ffe8b0000 CPU 24: data_offset = 0x1ffe5b0000 And we can see from dmesg that CPU 24 has an allocation on node 1: node 0: [mem 0x0000000000000000-0x0000000fffffffff] node 1: [mem 0x0000001000000000-0x0000001fffffffff] Fixes: 8c272261 ("powerpc/numa: Enable USE_PERCPU_NUMA_NODE_ID") Signed-off-by:
