      Improved the error cacheing. · 3976268c
      Stewart Brodie authored
        Removed DriversInKernel conditional.
      Detail:
        If the territory changes or the resource file changes, the kernel
          will now decache all the cached error blocks so that next time
          they are required, they will be looked up again.
        The error cacheing is now a kernel build option and is always set
          to on.
        Removed one of the 5 error messages to be cached - it never seems
          to happen.  The remaining 4 are more frequent.
      Admin:
        Tested in Ursula build.
        Cannot be used with HdrSrc 0.94.  HdrSrc 0.95 and later is required
          (or HdrSrc 0.93 and earlier subject to other kernel requirements)
        Requires MessageTrans 0.42 or later for correct operation when a
          replacement messages file is loaded.

        RPCEm update.
      * Register allocation in default ErrorV handler fixed - problems occured when
        callbacks were triggered on way out.
      * OS_Byte 19 didn't manipulate interrupt disable flag correctly in 26-bit
        builds.
      * Stray bit of debugging left in sprite code many years ago removed.

      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.
