These patches prepare i386 for paravirtualization by moving privileged and sensitive instructions into the BSP. The pc386 should operate as before, and no BSP is currently being provided for any particular hypervisor. We attempted to make the i386 similar to the paravirtualized sparc. Note that a paravirtualized i386 BSP still requires additional changes to newlib to deal with the use of cli/sti in longjmp, but otherwise should work if the BSP itself avoids privileged and sensitive instructions.
