François Revol	02283e080c	M68K: drop the custom C arch_cpu_user_mem*() for the default impl ... I didn't notice there was a C++ version that didn't require writing asm. I'll have to write them anyway for speed someday.	2016-07-20 21:57:19 +02:00
Paweł Dziepak	95e97463d2	kernel: add generic wrapper for accessing user memory ... 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.
