rGc7e0b94b7de7: riscv vmm: consider hart_mask_base argument in the SBI IPI handler.

Summary

From the spec

Any SBI function, requiring a hart mask, must take the following two arguments:

unsigned long hart_mask is a scalar bit-vector containing hartids
unsigned long hart_mask_base is the starting hartid from which the bit-vector must be computed.

hart_mask_base can be set to -1 to indicate that hart_mask shall be ignored and all available harts must be considered.

PS: I'll fix the TODO below, I just don't remember why did I put it there. Probably it is not needed anymore
