mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW.
- remove unnecessary UVMHIST_DECL's.

mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

thorpej 36780f9243 Make shmexit() and shmfork() take struct vmspace *'s, not struct proc *'s,
and update internal interfaces appropriately.

drochner 593f9e43c2 Fix error handling - call wakeup() in error case too. 1997-10-09 08:35:13 +00:00
drochner fa79dfb77e Use a swap pager backed VM object for sysV shm instead of kernel VM.
Mostly from FreeBSD.

christos 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.

cgd 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>.

christos 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).

pk 1e52ad70a9 We need some compat_10 routines if COMPAT_SUNOS is on (PR #1008). 1995-06-05 12:56:54 +00:00
christos 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

deraadt 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.

cgd 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.
