[PATCH] ARM: KVM: Fix unaligned unmap_range leak

by Christoffer Dall

The unmap_range function did not properly cover the case when the start address was not aligned to PMD_SIZE or PUD_SIZE and an entire pte table or pmd table was cleared, causing us to leak memory when incrementing the addr. The fix is to always move onto the next page table entry boundary instead of adding the full size of the VA range covered by the corresponding table level entry.

[PATCH 0/6] Tegra: Use cpufreq-cpu0 driver

by Viresh Kumar

Hi Stephen, This is the first attempt to get rid of tegra-cpufreq driver. This patchset tries to add supporting infrastructure for tegra to use cpufreq-cpu0 driver. I don't have hardware to test it and so is compiled tested only.. Few bits may be missing as I couldn't think of all aspects and so may need your help getting them fixed. Once this is tested by you, I would like to take it through my ARM cpufreq tree if nobody else has a problem with it. Thanks -- Viresh.

[PATCH] drm/agp: Fix build for non-AGP platforms

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Commit 28ec711 (drm/agp: move AGP cleanup paths to drm_agpsupport.c) broke the build for platforms which do not have AGP since it moved the AGP cleanup code inside an #ifdef __OS_HAS_AGP which are referenced unconditionally in drm_drv.c. This causes build failures for embedded SoCs which use DRM but do not have AGP. Fix this by providing stub static inlines in the header.

Do you know what the observable symptoms of this are? As this is a fix which needs to get into LSK I've added the linaro-kernel list to the cc so it has more public visibility.
