      32-bit Kernel. · b4016e9c
      Kevin Bracey authored
      Details:
        The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
        set to TRUE.
        If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
        although some internal changes have taken place to minimise compile
        switches between the two cases. See Docs.32bit for more technical info.
      
        The hardest part was the flood-fill...
      
      Other changes:
        Pointer shape changes now take place on the next VSync, rather than actually
        WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
        down by 5% now :)
      
        Lots of really crusty pre-IOMD code removed.
      
      Admin:
        Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
        will need to see a lot of use to iron out difficulties. I'd like anyone who
        has a non-frozen project to at least attempt using this Kernel.

      OS_ReadSysInfo 2 now reports whether the IIC bus is fast (in bit 24 of R2), and whether I/O clocks should be stopped when idling the processor (bit 25).
      
      OS_Byte 19 is a bit more careful in its use of Portable_Idle - an edge case
      where the vsync interrupt was already pending now returns immediately.
