cgd 0f2ecb72f6 lots of changes: prototype migration, move lots of variables, definitions,
and structure elements around.  kill some unnecessary type and macro
definitions.  standardize clock handling.  More changes than you'd want.

mycroft fbd4257135 Put `#ifdef notyet' around some code which is currently defunct. 1993-08-14 10:02:30 +00:00
andrew 22dff5862a Removed the user area protection gunk I painstakingly removed in revision
1.9.  It has not been necessary since then due to a segment fixup made to
machdep.c that prevents access to anything above MAX_VMUSER_ADDRESS.

*is* necessary, so put it back in...  it's in an #ifdef i386 part anyway.

andrew aa381d0e73 vm_protect() of the user area is no longer required for i386 machines; the
protection is implemented by adjusting the bounds of the user segment
descriptors.

mycroft d94e5eecbb Fix some off-by-one errors. 1993-06-29 13:47:05 +00:00
andrew 5705dde7e9 Disallow access to the user pages, where the kernel stack is stored. This
is effected in useracc(), and also by a vm_protect() in vm_fork() for i386
CPUs.  Without the latter a write to the user area, say USRSTACK+1000,
would hang a 386-based system.
