Hi.  As  far as I can tell,  PTRS_PER_PMD will evaluate to  512 when a
32-bit binary in userland makes a system call or has a page fault,
since TIF_32BIT will be set in the thread flags.

I suppose that means that for every second-level page table associated
with a 32-bit binary's process, there are (2048 - 512) unused
pmd entries.  Is that correct?
