If anyone has any objections, please let me know. ------------------ From: Helge Deller commit d24449864da5838936669618356b0e30ca2999c3 upstream. Currently the glibc isn't yet ported to 64-bit for hppa, so there is no usable userspace available yet. But it's possible to manually build a static 64-bit binary and run that for testing. One such 64-bit test program is available at http://ftp.parisc-linux.org/src/64bit.tar.gz and it shows various issues with the existing 64-bit syscall path in the kernel. This patch fixes those issues.
