* SVSHAPE0-3 for REMAP purposes, re-shaping Vector loops
* SVREMAP for applying specific shapes to specific registers
-If SVSTATE is all zeros then SV is disabled and the contents of the
-other SPRs SVSHAPE/SVREMAP are ignored.
-
-For Privilege Levels (trap handling) there are the following SPRs,
-where x may be u, s or h for User, Supervisor or Hypervisor
-Modes respectively:
-
-* (x)eSTATE (useful for saving and restoring during context switch,
- and for providing fast transitions)
-
-The u/s SPRs are treated and handled exactly like their (x)epc
-equivalents. On entry to or exit from a privilege level, the contents
-of its (x)SVSRR0 are swapped with SVSTATE.

# SVSTATE
This is a standard SPR that (REMAP aside) contains sufficient information for a
