drm/i915/vbt: split out defaults that are set when there is no VBT

2017-06-14T13:06:05Z

commit bb1d132935c2f87cd261eb559759fe49d5e5dc43 upstream. The main thing are the DDI ports. If there's a VBT that says there are no outputs, we should trust that, and not have semi-random defaults. Unfortunately, the defaults have resulted in some Chromebooks without VBT to rely on this behaviour, so we split out the defaults for the missing VBT case.

drm/i915/vbt: don't propagate errors from intel_bios_init()

2017-06-14T13:06:05Z

commit 665788572c6410b7efadc2e3009c5d830b6d8ef9 upstream. We don't use the error return for anything other than reporting and logging that there is no VBT. We can pull the logging in the function, and remove the error status return. Moreover, if we needed the information for something later on, we'd probably be better off storing the bit in dev_priv, and using it where it's needed, instead of using the error return. While at it, improve the comments.

serial: sh-sci: Fix panic when serial console and DMA are enabled

2017-06-14T13:06:04Z

commit 3c9101766b502a0163d1d437fada5801cf616be2 upstream. This patch fixes an issue that kernel panic happens when DMA is enabled and we press enter key while the kernel booting on the serial console. * An interrupt may occur after sci_request_irq(). * DMA transfer area is initialized by setup_timer() in sci_request_dma() and used in interrupt. If an interrupt occurred between sci_request_irq() and setup_timer() in sci_request_dma(), DMA transfer area has not been initialized yet. So, this patch changes the order of sci_request_irq() and sci_request_dma(). Fixes: 73a19e4c0301 ("serial: sh-sci: Add DMA support.")

drivers: char: mem: Fix wraparound check to allow mappings up to the end

2017-06-14T13:06:04Z

commit 32829da54d9368103a2f03269a5120aa9ee4d5da upstream. A recent fix to /dev/mem prevents mappings from wrapping around the end of physical address space. However, the check was written in a way that also prevents a mapping reaching just up to the end of physical address space, which may be a valid use case (especially on 32-bit systems). This patch fixes it by checking the last mapped address (instead of the first address behind that) for overflow.

drm/nouveau/tmr: fully separate alarm execution/pending lists

2017-06-14T13:06:04Z

commit b4e382ca7586a63b6c1e5221ce0863ff867c2df6 upstream. Reusing the list_head for both is a bad idea. Callback execution is done with the lock dropped so that alarms can be rescheduled from the callback, which means that with some unfortunate timing, lists can get corrupted. The execution list should not require its own locking, the single function that uses it can only be called from a single context. Signed-off-by: Ben Skeggs Signed-off-by: Greg Kroah-Hartman

drm/vmwgfx: Make sure backup_handle is always valid

2017-06-14T13:06:04Z

commit 07678eca2cf9c9a18584e546c2b2a0d0c9a3150c upstream. When vmw_gb_surface_define_ioctl() is called with an existing buffer, we end up returning an uninitialized variable in the backup_handle. The fix is to first initialize backup_handle to 0 just to be sure, and second, when a user-provided buffer is found, we will use the req->buffer_handle as the backup_handle.

drm/vmwgfx: limit the number of mip levels in vmw_gb_surface_define_ioctl()

2017-06-14T13:06:03Z

commit ee9c4e681ec4f58e42a83cb0c22a0289ade1aacf upstream. The 'req->mip_levels' parameter in vmw_gb_surface_define_ioctl() is a user-controlled 'uint32_t' value which is used as a loop count limit. This can lead to a kernel lockup and DoS. Add check for 'req->mip_levels'.
