Xen devel - Dec 2005 - [PATCH] If copy_to_user fails, return EFAULT

Tony Breeds and Rusty''s patches to add make check and make fullcheck 
allow you to run portions of the hypervisor under valgrind.  While doing 
this, I noticed that there are a lot of places in dom0_ops.c that we''re
either not checking the return value of copy_to_user or returning EINVAL 
instead of EFAULT.

The attach patch makes sure wherever we call copy_to_user we check for 
error and return EFAULT.

Regards,

Anthony Liguor
