Modified Files:
        src/sys/fs/tmpfs: tmpfs_vnops.c

Log Message:
Make tmpfs_getpages behave as genfs_getpages by ignoring the input pages
array's contents and returning all the requested pages.  Otherwise there
are problems (accessing invalid memory) when the a_m vector is passed
uninitialized as the NFS server code does.  Fixes PR kern/34959.

Note that this is not a "real" fix.  While this makes tmpfs's getpages
operation consistent with the behavior of other file systems, it does
not resolve the different semantics between uvn_get and uao_get as
described in PR kern/32166.  I'm adding a comment in the code mentioning
exactly this so that it can be reviewed when this last problem is
addressed.
