#     powerpc/32s: Simplify calculation of segment register content
#     
#     segment register has VSID on bits 8-31.
#     Bits 4-7 are reserved, there is no requirement to set them to 0.
#     
#     VSIDs are calculated from VSID of SR0 by adding 0x111.
#     
#     Even with highest possible VSID which would be 0xFFFFF0,
#     adding 16 times 0x111 results in 0x1001100.
#     
#     So, the reserved bits are never overflowed, no need to clear
#     the reserved bits after each calculation.
