[PATCH 08/24] alpha: select ARCH_HAS_FAST_MULTIPLIER

[Matt Turner]

All Alpha CPUs have hardware integer multiply (MULL/MULQ). EV4 and EV5
implement it in microcode; EV56 and later have fast single-cycle
multiply. Since no EV4 system is likely to run a modern kernel, select
this unconditionally to enable multiply-based fast paths in hweight and
string routines.
