Log Message:
Kenter local_apic_va to a fake physical page, because our x86
implementation expects this va to be valid even if no lapic is
present; which probably is a bug in itself, but let's just reproduce
the old behavior and rehide that bug.
This change (and the subsequent fix for the build break) breaks the installation process when running under pkgsrc/emulators/qemu-2.7.0nb1
Booting the install media image gets as far as the end of device auto-configuration, and hangs after reporting the boot device and /path/to/modules. It never gets to starting the init(8) process.
Reverting this fix (and the build break fix) restores the ability to finish booting, and actually gets into sysinst.
I don't know what the correct fix is, but I think we should revert this commit (at least for amd64, not sure about i386) until it is better understood and can be fixed properly.
This problem doesn't seem to be affecting the rel-eng amd64 test-bed, probably because it is likely running an older version of qemu?
XXX Note that this is not the only problem with amd64 on -HEAD. The rel-eng test-bed has not had a successful install for several days. It seems to "hang" and time-out while running 'progress cp /usr/mdec/boot /mnt2/boot' command. (My own system, after reverting the lapic changes, hangs at the exact same place.) Perhaps I should start a separate thread for this 2nd issue?
