I've requested a change for UPDATING:
The kerrnel option I386_CPU is now mutually exclusive with the
other cpu types. If you have an i386 system, be sure that it
only had this line. Remove it for all other configurations.
Note that this does not remove i386 support. The actual commit message
follows:
Modified files:
sys/i386/conf NOTES
sys/i386/i386 identcpu.c machdep.c pmap.c support.s
sys/pc98/conf GENERIC
sys/pc98/i386 machdep.c
Log:
Stop doing runtime checking on i386 cpus for cpu class. The cpu is
slow enough as it is, without having to constantly check that it really
is an i386 still. It was possible to compile out the conditionals for
faster cpus by leaving out 'I386_CPU', but it was not possible to
unconditionally compile for the i386. You got the runtime checking whether
you wanted it or not. This change makes I386_CPU mutually exclusive with
the other cpu types, and tidies things up a little in the process.
