Merge commit '517ffce4e1a03aea979fe3a18a3dd1761a24fafb' into arch-sparc
Backmerge from the point in mainline where a trivial conflict had been introduced (arch/sparc/kernel/sys_sparc_64.c had grown sys_kern_features() right after where kernel_execve() used to be) Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
