[PATCH 2/2] ARC: mm: fix new code about cache aliasing

Manual/partial revert of 8690bbcf3b70 ("Introduce cpu_dcache_is_aliasing() across all architectures") Current generation of ARCv2/ARCv3 based HSxx cores are only PIPT (to software at least). Legacy ARC700 cpus could be VIPT aliasing (based on cache geometry and PAGE_SIZE) however recently that s

recent kernel warning

Alexey, Can you have someone look at the following kernel warning:   DTC arch/arc/boot/dts/hsdk.dtb ../arch/arc/boot/dts/hsdk.dts:207.23-235.5: Warning (interrupt_provider): /soc/ethernet@8000: '#interrupt-cells' found, but node is not an interrupt provider arch/arc/boot/dts/hsdk.dtb: Warning

[PATCH v2 0/3] arch: Remove fbdev dependency from video helpers

Make architecture helpers for display functionality depend on general video functionality instead of fbdev. This avoids the dependency on fbdev and makes the functionality available for non-fbdev code. Patch 1 replaces the variety of Kconfig options that control the Makefiles with CONFIG_VIDEO. Mo

[PATCH v2 3/3] arch: Rename fbdev header and source files

The per-architecture fbdev code has no dependencies on fbdev and can be used for any video-related subsystem. Rename the files to 'video'. Use video-sti.c on parisc as the source file depends on CONFIG_STI_CORE. Further update all includes statements, includ guards, and Makefiles. Also update a fe

[PATCH v2 1/3] arch: Select fbdev helpers with CONFIG_VIDEO

Various Kconfig options selected the per-architecture helpers for fbdev. But none of the contained code depends on fbdev. Standardize on CONFIG_VIDEO, which will allow to add more general helpers for video functionality. CONFIG_VIDEO protects each architecture's video/ directory. This allows for t

[PATCH v2 2/3] arch: Remove struct fb_info from video helpers

The per-architecture video helpers do not depend on struct fb_info or anything else from fbdev. Remove it from the interface and replace fb_is_primary_device() with video_is_primary_device(). The new helper is similar in functionality, but can operate on non-fbdev devices. Signed-off-by: Thomas Zi
