powerpc: Add compat_sys_truncate The truncate syscall has a signed long parameter, so when using a 32- bit userspace with a 64-bit kernel the argument is zero-extended instead of sign-extended. Adding the compat_sys_truncate function fixes the issue. This was noticed during an LSB truncate test failure. The test was checking for the correct error number set when truncate is called with a length of -1. The test can be found at: http://bzr.linuxfoundation.org/lsb/devel/runtime-test?cmd=inventory;rev=stewb%40linux-foundation.org-20090626205411-sfb23cc0tjj7jzgm;path=modules/vsx-pcts/tset/POSIX.os/files/truncate/ BenH: Added compat_sys_ftruncate() as well, same issue.
