alpha: fix osf_wait4() breakage
kernel_wait4() expects a userland address for status - it's only rusage that goes as a kernel one (and needs a copyout afterwards) [ Also, fix the prototype of kernel_wait4() to have that __user annotation - Linus ] Fixes: 92ebce5ac55d ("osf_wait4: switch to kernel_wait4()") Cc: stable@kernel.org # v4.13+ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
