Since USER_PTRS_PER_PGD depends on TASK_SIZE and thus on the current
thread, it must not be used in code that can be called in the context
switch path (otherwise the 32-bitness of the outgoing task is used
here rather then the 32-bitness of the incoming one, possibly
resulting in large parts of the page tables not getting converted to
read-only).
