da17295d91 Calling shmdt(2) before calling shmat(2) would crash the system because
p->p_vmspace->vm_shm would be NULL. Protected the rest of the cases where
that might happen too. This was the reason why sunxdoom would panic the
system in SVR4 emulation.

3748c1aef7 try to insure that the 'default' address for shm segments is the same
from process to process.  It apparently is on SysV systems, and some
programs depend on this.  Suggested by  John Birrell <jb@werple.mira.net.au>.

1a5a3c9199 Extracted all of the compat_xxx routines, and created a library [libcompat]
for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy
or worth eliminating (yet).

fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile.
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by
	    COMPAT_HPUX. There should be a better way...
rest: Add #ifdef COMPAT_HPUX where needed

3938d6ba02 initialize shmmax to `# of pages' at compile time; multiply by NBPG at
boot time (in shminit). This supports architecture families with varying
values for NBPG, and does not break ipcs.

a128c34f9c From: Guido van Rooij <guido@gvr.win.tue.nl>
when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.
