0665a2b628 Increased stack size to 8MB just to be on the real safe side. 1993-09-01 09:38:32 +00:00

b722f788aa Changed trap.c so that a panic will occur if we do not have hardware
FP and we try to call the emulator when it is not compiled in.
Removed the #if defined(i486) || defined(i387) that use to call the
panic if we did not have a math emulator.
Removed an extranious include of i386/i386/math_emu.h from math_emulate.c.

3d93ce434a prefixed inline functions' parameter names with _ and declared
the return type explicitly.

fec9785d4c Corrected off by 2 error in DELAY macro (it was delaying for 2 * value).

773148e7ce Removed one more reverence to the old Adaptec 1542b as.c driver, one less
dependent for autoconf.c.

f604686b22 Moved _eintr{names,cnt} so that vmstat -i does not report all the debugging
stuff of the fast interrupt code.

95c4372f76 From guido@gvr.win.tue.nl Sat Aug 7 06:58:04 1993
I posted some patches on the 386bsd_patchkit list to prohibit io access.
Because of a noninitialised filed in the tss, this was possible.
It is included below as the patch to machdep.c
However, when you do this *necessary* fix (security), it will be
impossible form within user space to do io.

therefor, I included another fix: when you open /dev/io, you
get the access. Of course you can rewrite it to use another minor
and thus giving access to the iospace when /dev/mem is opened, e.g.

NOTE: The /dev/io entry has not been added to /dev/MAKEDEV yet.
The patch is in NetBSD.

06eedd4f1f Removed the asking for a root file system when booting from floppy as that
is now handled by the new boot blocks immediatly after the kernel is loaded.

ed0c248040 * Applied fixes from Bruce Evans to fix COW bugs, >1MB kernel loading,
profiling, and various protection checks that cause security holes
  and system crashes.
* Changed min/max/bcmp/ffs/strlen to be static inline functions
  - included from cpufunc.h in via systm.h. This change
  improves performance in many parts of the kernel - up to 5% in the
  networking layer alone. Note that this requires systm.h to be included
  in any file that uses these functions otherwise it won't be able to
  find them during the load.
* Fixed incorrect call to splx() in if_is.c
* Fixed bogus variable assignment to splx() in if_ed.c

6509993121 Added volatile void to cpu_exit() in the hope that it would
stop warning about returning from gcc.

It hasn't but the declaration is still correct.

f23626f7ea Updated kernel files to move occurances of "struct args" syscall
argument definitions outside of the function parameter list.  This is
to reduce the copious warning messages that (non-Jolitz) gcc produces.
Also fixed some bogus variable declarations and casts to make the
compiler happy.

25bd556275 Modified attach printf's so that the output is compatible with the "new"
way of doing things. There still remain several drivers that need to
be updated.  Also added a compile-time option to pccons to switch the
control and caps-lock keys (REVERSE_CAPS_CTRL) - added for my personal
sanity.

kernel, ps and w for this to work!

be449bcfcc Added (protection) around negative constants, in case a program wants
to use the negative of that constant.

#define NEG_NUM -3
#define SAFE_NEG_NUM (-3)

i = -NEG_NUM;		/* Error --3 */
j = -SAFE_NEG_NUM	/* Okay -(-3) */
