[SPARC64]: Fix most sparse warnings in arch/sparc64/kernel/sys_sparc.c
Sparse still doesn't like the funny cast we make from a scalar to a "union semun" (which is correct by the C language and in particular works with the sparc64 calling conventions, but sparse doesn't grok that yet). Signed-off-by: David S. Miller <davem@davemloft.net>
