SVN rev 215708 on 2010-11-22 20:46:38Z by bschmidt
Resurrect amd64 support.
- Many drivers on amd64 are picking system uptime, interrupt time and ticks
via global data structure instead of calling functions for performance
reasons. For now just patch such address so driver will not trigger page
fault when trying to access such data. In future, additional callout may
be added to update data in periodic intervals.
- On amd64 we need to allocate "shadow space" on stack before calling any
function.
