preserve_crunch_context() calls __copy_to_user() which expects the
destination address to be in __user space. setup_sigframe() properly
passes the destination address.
restore_crunch_context() calls __copy_from_user() which expects the
source address to be in __user space. restore_sigframe() properly
passes the source address.
This fixes {preserve/restore}_crunch_context() to accept the
address as __user space and resolves the following sparse warnings:
