ARM: uaccess: provide uaccess_save_and_enable() and uaccess_restore()
Provide uaccess_save_and_enable() and uaccess_restore() to permit control of userspace visibility to the kernel, and hook these into the appropriate places in the kernel where we need to access userspace. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
