Removed obsoletes EMUL_NO_BSD_ASYNCIO_PIPE and EMUL_NO_SIGIO_ON_READ flags. Async I/O OS specifities should now handled in OS specific code. Linux has been done, but other emulation should be handled. See case LINUX_F_SETFL in sys/compat/linux/common/linux_file.c:linux_sys_fcntl() for more details. The data that has been collected yet: Net Free Open Linux SunOS AIX OSF1 Darwin send SIGIO to write end of pipe Y N N N N N Y Y send SIGIO to read end of pipe Y Y N N N ? Y ? send SIGIO to write end of socket Y Y Y N N Y Y Y send SIGIO to read end of socket Y Y Y Y Y ? Y ?

/* $NetBSD: osf1_exec.c,v 1.24 2001/06/16 21:44:30 manu Exp $ */
exec internals have been moved (and improved) to osf1_exec.c. Not much there yet, but more to come.

restructure struct emul and execsw, in preparation to make emulations LKMable: * move all exec-type specific information from struct emul to execsw[] and provide single struct emul per emulation * elf: - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry per emulation and contains pointer to respective probe function - interp is allocated via MALLOC() rather than on stack - elf_args structure is allocated via MALLOC() rather than malloc() * ecoff: the per-emulation hooks moved from alpha and mips specific code to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per emulation supporting ecoff with appropriate probe function * the makecmds/probe functions don't set emulation, pointer to emulation is part of appropriate execsw[] entry * constify couple of structures

add e_path (emulation path) to struct emul, which replaces emulation-specific *_emul_path variables change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed change explicit emul_find() calls in probe functions to get the emulation path from the checked exec switch entry's emulation remove no longer needed header files add e_flags and e_syscall to struct emul; these are unsed and empty for now

Introduce 2 new flags in types.h: * __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by e_syscall_intern, which is called at key places in the kernel. This can be used to set a MD syscall handler pointer. This obsoletes and replaces the *_HAS_SEPARATED_SYSCALL flags. * __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in struct emul are omitted.
