This patch adds user_access() which can be used to gracefully handle page faults that may happen when accessing user memory. It is used by arch_cpu_user{memcpy, memset, strlcpy}() to allow using optimized functions from the standard library. Currently only x64 uses this, but nothing really is arch specific here.
