Re: Zero page

mrg@ pointed out (off-list) that sparc allocates such a page per-cpu.  Per-CPU
zeroed-page is for performance when used as a source of zeroes.  In my case,
the page is used to redirect user pages to unallocated blocks in a file.
What matters here is to reduce memory consumption.  So I've decided to
allocated a single page only "options XIP".

(I'll revisit to unify such an MD zeroed-page interface later.)
