Detail:
 * Stopped calling the broken abort fixup code when running under VMSAv6.
   Might be desirable to update it, possibly farmed out to a separate module -
   still need to think about this.
 * Unaligned load optimisations can now be disabled by the global NoUnaligned
   flag for testing purposes.
 * Extended OS_ReadUnsigned to permit reading of 64-bit unsigned integers.
   See Docs.ReadUnsigned for more details. Also sped it up by using MLA
   (or UMLAL) for most digits rather than repeated addition.
 * Bugfix is OS_GSRead: an uninitialised r0 was being passed to
   OS_ReadUnsigned, causing undesirable effects on rare occasions.
Admin:
  Tested on a rev B7 beagleboard.

Version 5.35, 4.79.2.98.2.8. Tagged as 'Kernel-5_35-4_79_2_98_2_8'

Detail:
  * Merged in the change to RISC OS 4.02 kernel that moved the GSTrans
    workspace out of scratch space.
  * Fixed a few bugs in callback postponement, and interrupt holes in
    callback dispatch. See Docs.CallbackChange for full info.
  * Fixed SystemSizeCMOS to SysHeapCMOS - wouldn't build as was.
  * Added an export of a C version of Hdr:HALDevice, based on the Hdr2H
    translation but with an additional struct definition. Required by
    SoundControl 1.00.
  * Added some additional location and ID allocations to Hdr:HALDevice.
    Required by today's HAL and SoundControl.
Admin:
  Partially tested.

Version 5.35, 4.79.2.56. Tagged as 'Kernel-5_35-4_79_2_56'

Detail:
  Lots of changes since last version, at least the following:
  * Updated OS timestamp, removed alpha status
  * Negative INKEY OS version changed to &AA
  * GraphicsV is now alocated vector number &2A
  * ROM moved up to &FC000000
  * Max application slot increased to 512 Mbytes (for now)
  * Max size of RMA increased to 256 Mbytes
  * RMA is now first-created dynamic area (so it gets lowest address after
    top of application slot)
  * OS_Memory 10 reimplemeted
  * New OS_ReadSysInfo 6 values 18-22 added
  * OS_ReadSysInfo 8 gains flag bit to indicate soft power-off
  * Misc internal top-bit-set-address fixes
  * *ChangeDynamicArea can take sizes in megabytes or gigabytes
  * Magic word "&off" in R0 passed to OS_Reset powers down if possible
  * Added acceleration: block copy; CLS; text window scroll up; rectangle
    fill
  * Disabled LED flashing in page mode (liable to crash)
  * Masked sprite plot and VDU 5 text avoids reading the screen if poss...

Look for LongCommandLine flag, command line size currently
set at 1k.
For HAL/32bit builds, the kernel buffer space is at high
(top bit set) address, which may break some code using signed
comparisons. So *beware* that there may be some latent
bugs in old kernel code using these buffers, not yet found.
One such bug, in s.Arthur2 found and fixed.
Tested moderately on ARM9 desktop build.
Lovely to reimplement things I did two and half years ago.

Version 5.35, 4.79.2.37. Tagged as 'Kernel-5_35-4_79_2_37'

* 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'

*Set Sys$Year would scramble the time. It would also fail to internationalise the error generated by *Set Year 20000.

Tested on a 32-bit system - changes grafted back on to 26-bit Kernel.

Version 5.08. Tagged as 'Kernel-5_08'

Version 4.84. Tagged as 'Kernel-4_84'

Bandwidth limit for 7500FE fixed.
RO371Timings flag set to :LNOT:STB
