[ARM] Fix sys_sendto and sys_recvfrom 6-arg syscalls
Rather than providing more wrappers for 6-arg syscalls, arrange for them to be supported as standard. This just means that we always store the 6th argument on the stack, rather than in the wrappers. This means we eliminate the wrappers for: * sys_futex * sys_arm_fadvise64_64 * sys_mbind * sys_ipc Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
