9ad861edee - For some old Cyrix CPUs, %cr2 is clobbered by interrupts. This 
problem is worked around by using an interrupt gate for the page
   fault handler.  This code was originally made for NetBSD/pc98 by
   Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already
   been in PC98 tree.  Because of this bug, trap_fatal cannot show
   correct page fault address if %cr2 is obtained in this function.
   Therefore, trap_fatal uses the value from trap() function.
-  The trap handler always enables interruption when buggy application
   or kernel code has disabled interrupts and then trapped.  This code
   was prepared by Bruce Evans <bde@FreeBSD.org>.

88a92ff10e Even though BIOS writer's guide recommends cpuid instruction of Cyrix 
6x86MX CPU is enabled (BIOS should not disable it), some BIOS disables
it via CCR4.  In this case, cpu variable becomes CPU_486 and
identblue() is called.  Because Cyrix 6x86MX has MSR and doesn't have
MSR1002, wrmsr instruction generates general protection fault.

and only I/O access (undocumented) can do that.  If PG_N is used,

9caaadb63a Changed the way that the exec image header is read to be filesystem- 
centric rather than VM-centric to fix a problem with errors not being
detectable when the header is read.
Killed exech_map as a result of these changes.
There appears to be no performance difference with this change.
