[Qemu-devel] RFC: [1/11] EFAULT patch

[Stuart Anderson]

This first part contains the additions to the existing infrastructure
needed to implement the new interfaces used in the rest of the patch.

In exec.c, page_check_range() has been added to take an address and a
size and and check to see if it is contained in a valid page that
belongs to the target. A flag is passed t indicate wether read or write
access should be checked.

In qemu.h, the access_ok macro has been given a real implemention, and
implementations of copy_from_user() and copy_to_user() have been added.
