 * Sharing the TLB between multiple VPEs means that the
 * "random" index selection function is not allowed to
 * select the current value of the Index register. To
 * avoid additional TLB pressure, the Index registers
 * are "parked" with an non-Valid value.

#define PARKED_INDEX    ((unsigned int)0x80000000)

 * Define low-level interrupt mask for IPIs, if necessary.
 * By default, use SW interrupt 1, which requires no external
 * hardware support, but which works only for single-core
 * MIPS MT systems.
