The Tilera hypervisor shipped in releases up through MDE 4.1 launches the client operating system (i.e. Linux) at privilege level 1 (PL1). Starting with MDE 4.2, as part of the work to enable KVM, the Tilera hypervisor launches Linux at PL2 instead. This commit makes the KERNEL_PL option default to 2 for tilegx, while still saying at 1 for tilepro, which doesn't have an updated hypervisor. It also explains how and when you might want to choose another value. In addition, we change a small buglet in the on-chip Ethernet driver, where we were failing to use the KERNEL_PL constant in an API call. To make the transition cleaner, this change also provides the updated hv_init() API for the new hypervisor that supports announcing Linux's compiled-in PL, so the hypervisor can generate a suitable error in the case of a mismatched hypervisor and Linux binary.
