christos 4d9a6e0930 - Pass the Elf32_Ehdr in the linux probe function, and use it!
Since linux binaries are (mostly) always compiled with gcc, look for
the gcc signature in the .comment section header: "\0 GCC: (GNU) ".
I've changed the probe order in kern/exec_elf.c to probe for linux ELF
binaries first and fall back to SVR4 binaries. This makes statically
linked binaries work for both linux and svr4. Note that gcc-compiled
svr4 binaries, still contain the operating system signature first and
then the GCC signature, so there is no conflict. Yes this is a hack.

mycroft ad790f628e Turn off the trace flag when delivering a signal. 1996-04-12 08:44:35 +00:00
mycroft 48643c6605 Export [gs]et_vflags(), and always use them when saving/restoring registers
in VM86 mode.
Allow changing of *all* PSL bits in VM86 mode; some applications don't work
right otherwise, and all the nasty bits are virtualized anyway.
Make sure PSL_VIF, PSL_VIP, and PSL_VM don't show up in the user's view of
the PSL.

fvdl 82079ba5b3 Work around calling the NetBSD fcntl(F_{G,S}ETOWN) for now; it is too
