Hash: SHA1

I have an application I'm building which requires OS support to allow  
a user-space function to fill a page on page-faults.  Ideally, I  
could reserve a chunk of address space but not back it with memory,  
and then on fault my handler would serve out data from some small  
cache of user-managed physical pages.

My google-fu has been weak in finding such a system-level API in any  
OS.  Has this got a name I should be searching on?  I can't believe  
no-one has implemented user-level page replacement.

Thanks,
    Paul
