2017-06-20gpio: mvebu: change compatible string for PWM supportRalph Sennhauser1-3/+3
As it turns out more than just Armada 370 and XP support using GPIO lines as PWM lines. For example the Armada 38x family has the same hardware support. As such "marvell,armada-370-xp-gpio" for the compatible string is a misnomer. Change the compatible string to "marvell,armada-370-gpio" before the driver makes it out of the -rc stage. This also follows the practice of using only the first device family supported as part of the name. Also update the documentation and comments in the code accordingly.

2017-06-19mm: larger stack guard gap, between vmasHugh Dickins1-0/+7
Stack guard page is a useful feature to reduce a risk of stack smashing into a different mapping. We have been using a single page gap which is sufficient to prevent having stack adjacent to a different mapping. But this seems to be insufficient in the light of the stack usage in userspace. E.g. glibc uses as large as 64kB alloca() in many commonly used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX] which is 256kB or stack strings with MAX_ARG_STRLEN. This will become especially dangerous for suid binaries and the default no limit for the stack size limit because those applications can be tricked to consume a large portion of the stack and a single glibc call could jump over the guard page. These attacks are not theoretical, unfortunatelly. Make those attacks less probable by increasing the stack guard gap to 1MB (on systems with 4k pages; but make it depend on the page size because systems with larger base pages might cap stack allocations in the PAGE_SIZE units) which should cover larger alloca() and VLA stack allocations. It is obviously not a full fix because the problem is somehow inherent, but it should reduce attack space a lot. One could argue that the gap size should be configurable from userspace, but that can be done later when somebody finds that the new 1MB is wrong for some special case applications. For now, add a kernel command line option (stack_guard_gap) to specify the stack gap size (in page units). Implementation wise, first delete all the old code for stack guard page: because although we could get away with accounting one extra page in a stack vma, accounting a larger gap can break userspace - case in point, a program run with "ulimit -S -v 20000" failed when the 1MB gap was counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK and strict non-overcommit mode. Instead of keeping gap inside the stack vma, maintain the stack guard gap as a gap between vmas: using vm_start_gap() in place of vm_start (or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few places which need to respect the gap - mainly arch_get_unmapped_area(), and and the vma tree's subtree_gap support for that.

https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux into drm-next sun4i-drm changes for 4.13 An unusually big pull request for this merge window, with three notable features: - V3s display engine support. This is especially notable because it uses a different display engine used on the newer Allwinner SoCs (H3, A64 and the likes) that will be quite easily supported now. - HDMI support for the old Allwinner SoCs. This is enabled only on the A10s for now, but should be really easy to extend to deal with A10, A20 and A31 - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3, etc.). It currently ignores the second pipeline, but we can use the dual-pipelines bindings. This will be useful to enable the display pipeline while we work on the dual-pipeline. * tag 'sunxi-drm-for-4.13' of https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux: (27 commits) drm/sun4i: Add compatible for the A10s pipeline drm/sun4i: Add HDMI support dt-bindings: display: sun4i: Add allwinner,tcon-channel property dt-bindings: display: sun4i: Add HDMI display bindings drm/sun4i: Ignore the generic connectors for components drm/sun4i: tcon: multiply the vtotal when not in interlace drm/sun4i: tcon: Change vertical total size computation inconsistency drm/sun4i: tcon: Fix tcon channel 1 backporch calculation drm/sun4i: tcon: Switch mux on only for composite drm/sun4i: tcon: Move the muxing out of the mode set function drm/sun4i: tcon: Add channel debug drm/sun4i: tcon: add support for V3s TCON drm/sun4i: Add compatible string for V3s display engine drm/sun4i: add support for Allwinner DE2 mixers drm/sun4i: add a Kconfig option for sun4i-backend drm/sun4i: abstract a engine type drm/sun4i: return only planes for layers created dt-bindings: add bindings for DE2 on V3s SoC drm/sun4i: backend: Clarify sun4i_backend_layer_enable debug message drm/sun4i: Set TCON clock inside sun4i_tconX_mode_set ...

2017-06-01dt-bindings: display: sun4i: Add allwinner,tcon-channel propertyMaxime Ripard1-4/+7
The Allwinner Timings Controller has two, mutually exclusive, channels. When the binding has been introduced, it was assumed that there would be only a single user per channel in the system. While this is likely for the channel 0 which only connects to LCD displays, it turns out that the channel 1 can be connected to multiple controllers in the SoC (HDMI and TV encoders for example). And while the simultaneous use of HDMI and TV outputs cannot be achieved, switching from one to the other at runtime definitely sounds plausible. Add an extra property, allwinner,tcon-channel, to specify for a given endpoint which TCON channel it is connected to, while falling back to the previous mechanism if that property is missing.

There is a patch hitting drivers/firmware/* that I was uncertain to who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's review tags on it and I trust them both 100% to do the right thing for Intel platform drivers. Summary: - Make a few Intel Chromebooks with Cherryview DMI firmware work smoothly. - A fix for some bogus allocations in the generic group management code. - Some GPIO descriptor lookup table stubs. Merged through the pin control tree for administrative reasons. - Revert the "bi-directional" and "output-enable" generic properties: we need more discussions around this.
