  Hash : 4ed6f7c2
  Message : Delete the last emulation callbacks: we're Just ELF, so declare exec_elf_fixup() and coredump_elf() in <sys/exec_elf.h> and call them and the MD setregs() directly in kern_exec.c and kern_sig.c Also delete e_name[] (only used by sysctl), e_errno (unused), and e_syscallnames[] (only used by SYSCALL_DEBUG) and constipate syscallnames to 'const char *const[]' ok kettenis@
