[patch v2 0/2] x86/dumpstack: Prevent access to foreign tasks user space

[Thomas Gleixner]

This is the second version of the patch to prevent access to a foreign
tasks user space in copy_code(). It addresses the review comments from
Boris and adds a new patch which provides documentation for
copy_from_user_nmi() to avoid further confusion about it's usage.
