4c56fcdead Removed the cast to a pointer in the definition of PS_STRINGS and
adjusted related casts to match (only in the kernel in this commit).
The pointer was only wanted in one place in kern_exec.c.  Applications
should use the kern.ps_strings sysctl instead of PS_STRINGS, so they
shouldn't notice this change.

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  This code was originally made for NetBSD/pc98 by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>.

582e52862a - hw.machine_arch returns cpu architecture type.
- moved definition of MACHINE_ARCH from cpu.h to parm.h as alpha.
- Added definitions of _MACHINE and _MACHINE_ARCH.
- Added hw.ispc98. The hw.ispc98 is 1 in PC98 kernel and is 0 in
  IBM-PC kernel.

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.

cf478d7b45 Don't use PG_N if EPSON PC-486HX/HG/HA (PC-9801 compatible) are
detected.  These machine cannot make L2 cache write-through by PG_N,
and only I/O access (undocumented) can do that.  If PG_N is used,
system hangs.
