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 possible
  * Framestore made USR mode accessible
  * Fix for VDU 5,127 bug - now relies on font definitions being in extreme
    quarters of memory, rather than bottom half
  * Allocated 64-bit OS_Convert... SWIs
  * IIC errors use allocated error numbers
  * Looks for Dallas RTC before Philips RTC because we're using a Philips
    NVRAM device with the same ID
  * Fix to bug that meant the oscillator in the Dallas RTC wasn't enabled
  * Default mouse type (USB) changed to allocated number
  * Ram disc max size increased to 128 Mbytes (Ursula merge) and made
    cacheable for StrongARMs (not XScale)
  * Branch through zero handler now works in USR mode, by use of a
    trampoline in the system stack to allow PC-relative register storage
  * Address exception handler changed to not use 0 as workspace
  * OS_Memory 13 extended to allow specification of cacheability and access
    privileges
  * Added OS_Memory 16 to return important memory addresses
  * RISCOS_MapInIO() takes cacheable flag in bit 3, access permissions in
    bits 10 and 11, doubly-mapped flag in bit 20, and access permissions
    specified flag in bit 21
  * Bug fix in last version for application abort handlers didn't quite
    work; register shuffle required
  * "Module is not 32-bit compatible" error now reports the module name
  * Default configured language changed from 10 to 11 (now Desktop again)

Version 5.35, 4.79.2.51. Tagged as 'Kernel-5_35-4_79_2_51'

Version 5.35, 4.79.2.48. Tagged as 'Kernel-5_35-4_79_2_48'

Check-in of the few last-minute changes for the Customer L demo. Nothing exciting, apart from an extended touchscreen API.

Version 5.35, 4.79.2.13. Tagged as 'Kernel-5_35-4_79_2_13'

Detail:
  When Machine=Phoebe the Kernel failed to build due to use of OSVersionID.
  Commented out this line.  Other machine settings unaffected.
Admin:
  Tested on Ursula build: Products/Ursula/modules (tag Ursula010a).

Version 5.19. Tagged as 'Kernel-5_19'

STB and NC builds. Remerged correctly.

Version 5.16. Tagged as 'Kernel-5_16'

  Ensured that M_Phoebe builds set UtilityModule version to 4.00
Detail:
  The softload utility relies on the existence of the extra reason codes
    to OS_ReadSysInfo introduced in Ursula.  The main kernel now supports
    these too (they are simply interfaces to read kernel capabilities and
    configuration - eg. addresses and sizes of UND and SVC mode stacks)
  Avoid OS_ReadSysInfo 9 - ROL have used it for reading the ROM personality
    information (and it's not in our kernel)
  Added some of the new macros into Copro15ops required by the ABT dump
    area code (returned by OS_ReadSysInfo 7) and added the code into ARM600
    to store abort information there.
Admin:
  Required by softload utility for Ursula builds.
  Tested on Risc PC.

Version 5.15. Tagged as 'Kernel-5_15'

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

Version 4.64. Tagged as 'Kernel-4_64'

Not fully tested on all hardware permutations.
