2018-04-17drm/exynos: Move GEM BOs to drm_framebufferDaniel Stone1-35/+4
Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those.

2018-04-16MIPS: memset.S: EVA & fault support for small_memsetMatt Redfearn1-1/+6
The MIPS kernel memset / bzero implementation includes a small_memset branch which is used when the region to be set is smaller than a long (4 bytes on 32bit, 8 bytes on 64bit). The current small_memset implementation uses a simple store byte loop to write the destination. There are 2 issues with this implementation: 1. When EVA mode is active, user and kernel address spaces may overlap. Currently the use of the sb instruction means kernel mode addressing is always used and an intended write to userspace may actually overwrite some critical kernel data. 2. If the write triggers a page fault, for example by calling __clear_user(NULL, 2), instead of gracefully handling the fault, an OOPS is triggered. Fix these issues by replacing the sb instruction with the EX() macro, which will emit EVA compatible instuctions as required. Additionally implement a fault fixup for small_memset which sets a2 to the number of bytes that could not be cleared (as defined by __clear_user).

2018-04-16Merge branch 'mm-rst' into docs-nextJonathan Corbet72-2211/+2610
Mike Rapoport says: These patches convert files in Documentation/vm to ReST format, add an initial index and link it to the top level documentation. There are no contents changes in the documentation, except few spelling fixes. The relatively large diffstat stems from the indentation and paragraph wrapping changes. I've tried to keep the formatting as consistent as possible, but I could miss some places that needed markup and add some markup where it was not necessary. [jc: significant conflicts in vm/hmm.rst]
