    MIPS: Outline udelay and fix a few issues. · 5636919b
    Ralf Baechle authored
    Outlining fixes the issue were on certain CPUs such as the R10000 family
    the delay loop would need an extra cycle if it overlaps a cacheline
    boundary.
    
    The rewrite also fixes build errors with GCC 4.4 which was changed in
    way incompatible with the kernel's inline assembly.
    
    Relying on pure C for computation of the delay value removes the need for
    explicit.  The price we pay is a slight slowdown of the computation - to
    be fixed on another day.
