[SUNRPC]: svc_{get,put}nl()
* add svc_getnl(): Take network-endian value from buffer, convert to host-endian and return it. * add svc_putnl(): Take host-endian value, convert to network-endian and put it into a buffer. * annotate svc_getu32()/svc_putu32() as dealing with network-endian. * convert to svc_getnl(), svc_putnl(). [AV: in large part it's a carved-up Alexey's patch] Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S.
