branch 'uaccess' (batched user access infrastructure) Expose an interface to allow users to mark several accesses together as being user space accesses, allowing batching of the surrounding user space access markers (SMAP on x86, PAN on arm64, domain register switching on arm). This is currently only used for the user string lenth and copying functions, where the SMAP overhead on x86 drowned the actual user accesses (only noticeable on newer microarchitectures that support SMAP in the first place, of course). * user access batching branch: Use the new batched user accesses in generic user string handling Add 'unsafe' user access functions for batched accesses x86: reorganize SMAP handling in user space accesses # < /opt/cross/arcv2-buildroot-2015.08.1/bin/arc-buildroot-linux-uclibc-gcc --version # < git log --format=%s --max-count=1
