Ripping out /dev/mem support

[Corinna Vinschen]

Hi guys,


what do you think about ripping out support for /dev/mem? It's an
entire fhandler which just doesn't make sense anymore due to lack of
support in the OS. The only remaining supported OS, which allows to
access \Device\PhysicalMemory from user space is Windows XP 32 bit. Not
even XP64 or 2003 allowed it anymore, not to mention Vista and later.
Keeping it up for a single, dying OS and for questionable purposes
doesn't make a lot of sense, IMHO.

This would only make sense if all systems support it, which requires to
write a device driver kind of like ioperm. Worse, it would have to be
signed for 64 bit systems.
