sys_stat() and friends, instead use do_sys_stat() and do_sys_fstat() that write the answer into a kernel buffer (on stack) that can be converted to the correct form and written the userspace. I've test compiled a few kernels, and tested i386 netbsd1.6 ls. Given I think I've fixed some bugs, it might be 50-50 with new ones.
