CVS commit: src/sys/kern

["Maxime Villard" <maxv%netbsd.org@localhost>]

Module Name:    src
Committed By:   maxv
Date:           Wed Jun 25 16:35:13 UTC 2014

Modified Files:
        src/sys/kern: subr_kmem.c

Log Message:
1) Make clear that we want the space allocated for the KMEM_SIZE header to be
   aligned, by using kmem_roundup_size(). There's no functional difference with
   the current MAX().

2) If there isn't enough space in the page padding for the red zone, allocate
   one more page, not just 2 bytes. We only poison 1 or 2 bytes in this page,
   depending on the space left in the previous page. That way 'allocsz' is
   properly aligned. Again, there's no functional difference since the shift
   already handles it correctly.
