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

Module Name:    src
Committed By:   maxv
Date:           Mon Jul 27 09:24:28 UTC 2015

Modified Files:
        src/sys/kern: subr_kmem.c
        src/sys/uvm: files.uvm
Removed Files:
        src/sys/uvm: uvm_kmguard.c uvm_kmguard.h

Log Message:
Several changes and improvements in KMEM_GUARD:
 - merge uvm_kmguard.{c,h} into subr_kmem.c. It is only user there, and
   makes it more consistent. Also, it allows us to enable KMEM_GUARD
   without enabling DEBUG.
 - rename uvm_kmguard_XXX to kmem_guard_XXX, for consistency
 - improve kmem_guard_alloc() so that it supports allocations bigger than
   PAGE_SIZE
 - remove the canary value, and use directly the kmem header as underflow
   pattern.
 - fix some comments

(The UAF fifo is disabled for the moment; we actually need to register
the va and its size, and add a weight support not to consume too much
memory.)
