  Log:
  Protect all modifications to paging_in_progress with splvm().  The i386
  managed to avoid corruption of this variable by luck (the compiler used a
  memory read-modify-write instruction which wasn't interruptable) but other
  architectures cannot.
  
  With this change, I am now able to 'make buildworld' on the alpha (sfx: the
  crowd goes wild...)
