[PATCH] i386: need to pass virtual address to smp_read_mpc()
I'm seeing a kernel panic on an ES7000-600 when booting in virtual wire
mode. The panic happens because smp_read_mpc() is passed a physical
address, and it should be virtual. I tested the attached patch on the
ES7000-600 and on a 2 cpu Dell box, and saw no problems on either.
