Jérôme Duval b25103cc9c kernel: generic user_memcpy() should clear_ac after the fault handler returns ...

the AC flag in eflags/rflags, pushed in the iframe by the CPU, is kept intact after handling the exception, since the fault handler is run with the faulted iframe and does a simple jump. The AC flag would otherwise be set until the syscall returns to userland.
