Use the 32-bit compat keyctl() syscall wrapper on Sparc64 for Sparc32 binary compatibility. Without this, keyctl(KEYCTL_INSTANTIATE_IOV) is liable to malfunction as it uses an iovec array read from userspace - though the kernel should survive this as it checks pointers and sizes anyway. I think all the other keyctl() function should just work, provided (a) the top 32-bits of each 64-bit argument register are cleared prior to invoking the syscall routine, and the 32-bit address space is right at the 0-end of the 64-bit address space. Most of the arguments are 32-bit anyway, and so for those clearing is not required. Signed-off-by: David Howells <dhowells@redhat.com cc: "David S.
