[Xen-devel] [PATCH] x86/nops: Switch to the P6 nops as a compile-time default

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Along with c/s d7128e735031 switching the runtime choice of best nops, switch
the compile-time default to P6 nops.  This is more efficient on most
processors for alternative points which add/remove code, rather than switch
between two different pieces of code.
