  Log:
  Fix overflow, which was causing endless loops when 32bit machine had more
  than 2GB of RAM. This was because our physmem is long and 'physmem*PAGESIZE'
  can be negative for more than 2GB of memory.

  Reported by:    Andrey V. Elsukov <bu7cher at yandex.ru>

  It is not yet tested by Andrey, so there can be other problems, but this
  was definiately a bug, so I'm committing a fix now.
