Subject: arm64: cache: Merge cachetype.h into cache.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02f7760e6e5c3d726cd9622749cdae17c571b9a3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm64: cache: Merge cachetype.h into cache.h

cachetype.h and cache.h are small and both obviously related to caches.
Merge them together to reduce clutter.
