Patch 1 adds aarch64 implementations of cl_flush() and sb() in fill_buf.c so cache flushes are no longer silent no-ops. Patch 2 teaches detect_vendor() about aarch64 (which exposes no vendor_id in /proc/cpuinfo) and lets arch_supports_noncont_cat() return true for ARM, fixing spurious L3_NONCONT_CAT failures. Changes since v4: - Drop v4 patch 1/3, which was applied to linux-kselftest/next. - Rebase the remaining patches onto linux-kselftest/next and renumber v4 patches 2/3 and 3/3 as patches 1/2 and 2/2. No code changes to the remaining patches.
