Detail:
  s/ChangeDyn:
    - Apply various optimisations to OS_ChangeDynamicArea to reduce the execution time when performing large grows/shrinks.
    - Optimisations can be toggled on/off with FastCDA_* flags for debugging.
    - On a 1GHz 512MB BB-xM, the initial *FreePool call now takes 0.15s instead of 13.46s. On a 512MB Iyonix the time has dropped from 1.18s to 0.23s.
    - Growing screen memory (on BB-xM) has also seen significant gains - between 2x and 4x speedup, depending on what state the source pages are in.
    - Added/updated documentation for a few functions and made more use of ROUTs for safety
  s/ARM600, s/VMSAv6:
    - Update BangCamUpdate, etc. to add support for the PageFlags_Unsafe flag that OS_ChangeDynamicArea uses to bypass cache/TLB maintenance in some situations
    - Avoid BangCamUpdate calling BangL2PT to map out the page if the page isn't mapped in (avoids unnecessary cache/TLB flush)
  s/ArthurSWIs:
    - Add extra ASSERT for safety
  s/AMBcontrol/memory
    - Fix incorrect assumption that the usable size of a heap block is always 8 less than the value stored in the header. Even with the old 8 byte aligned allocations the usable size will always be 4 bytes less than the value in the header. This code would have resulted in some slight memory wasteage, as AMBcontrol will have always tried growing the block four bytes bigger than needed.

Version 5.35, 4.79.2.146. Tagged as 'Kernel-5_35-4_79_2_146'

Version 5.35, 4.79.2.12. Tagged as 'Kernel-5_35-4_79_2_12'

* Added ARM_IMB and ARM_IMBRange SWIs as recommended by ARMv5.
* Some early prototype HAL bits popped in - a lot of source restructuring still
  to come.
* New debug target creates an AIF image with debug information, and translates
  this into an ASCII object file for the 16702B logic analyser.

Version 5.35, 4.79.2.1. Tagged as 'Kernel-5_35-4_79_2_1'

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.

Version 5.23. Tagged as 'Kernel-5_23'
