  Log:
  Support crash dumps > 4GB in size on 32 bit platforms.  _kvm_kvatop()
  returned an lseek offset in a "u_long *" value, which can't express >4GB
  offsets on 32 bit machines (eg: PAE).  Change to "off_t *" for all.
  
  Support ELF crashdumps on i386 and amd64.
  
  Support PAE crashdumps on i386.  This is done by auto-detecting the
  presence of the IdlePDPT which means that PAE is active.
  
  I used Marcel's _kvm_pa2off strategy and ELF header reader for ELF support
  on amd64.  Paul Saab ported the amd64 changes to i386 and we implemented
  the PAE support from there.
  
  Note that gdb6 in the src tree uses whatever libkvm supports.  If you want
  to debug an old crash dump, you might want to keep an old libkvm.so handy
  and use LD_PRELOAD or the like.  This does not detect the old raw dump
  format.
