        src/sys/arch/amd64/amd64: cpu.c machdep.c vm_machdep.c

Log Message:
Make the IDT read-only. It's only mapped R/W when really needed. Could
catch disasters such as overwriting it. Should probably be made
conditional on DIAGNOSTIC later, but there's no time-critical code
involved here.

Move the double fault stack away from the IPI stack. It's now shared
between CPUs, but that's not a big deal; double faults are fatal
and can't be recovered from.
