11e2bfb4b6 Sync with sys/i386/i386/machdep.c revision 1.339. 
New function getmemsize_pc98 is added in this commit, since PC98 is
quite different in obtaining memory size from IBM-PC.  Many lines of
this function is shareable with IBM-PC's getmemsize function, but
sharing needs many #ifdef PC98 statements.  Therefore, I gave up
sharing code with IBM-PC's and just added new function.

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  This code was originally made for NetBSD/pc98 by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

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.
