This requires an architecture specific compat routine as u64s are passed in odd/even (high/low) register pairs on ppc32. Signed-off-by: Stephen Rothwell <redacted> --- arch/powerpc/kernel/sys_ppc32.c | 9 +++++++++ include/asm-powerpc/systbl.h | 1 + include/asm-powerpc/unistd.h | 3 ++- 3 files changed, 12 insertions(+), 1 deletions(-) David, the other two missing syscalls were wired up in the previous patch set I sent today. Thanks for your patch to push us along. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
