Similar to the problems I fixed for posix_fallocate <http://sourceware.org/ml/libc-ports/2008-12/msg00007.html> and fallocate <http://sourceware.org/ml/libc-ports/2009-05/msg00031.html>, MIPS64 posix_advise also needs fixes to use the correct syscall interfaces. Although the existing n32 posix_fadvise64 is OK, getting posix_fadvise from syscalls.list does not work correctly, as this function is supposed to return an error code instead of storing it in errno as the generic syscall implementations from syscalls.list do.
