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.

4fe88fe637 Restore support for executing BSD/OS binaries on the i386 by passing 
the address of the ps_strings structure to the process via %ebx.
For other kinds of binaries, %ebx is still zeroed as before.

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  This code was originally made for NetBSD/pc98 by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

- 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.
