sys/arch/i386/i386: cpu.c
Log message:
Only read/write cr4 if we have a bit to set after testing the various
cpuid based flags.
Unlike amd64 there is no CR4_DEFAULT used here, cr4 does not exist
on most/all? 486s and cr4 access traps on Cyrix 5x86 processors.
Should fix a regression introduced in rev 1.65 encountered
by 'Ppractivus' on a 5x86.
