[Xen-devel] [PATCH] Page scrubbing

["Christoph Egger" <Christoph.Egger@xxxxxxx>]

Hi!

Make scrub_heap_pages() print from where to where
it scrubs pages.

Signed-off-by: Christoph Egger <Christoph.Egger@xxxxxxx>


This patch uncovers a strange behaviour on 32bit.
On 64bit I get this:

(XEN) Scrubbing Free RAM 0xffff830000100000 -> 0xffff83003fff0000: ....done.

On 32bit I get this:

(XEN) Scrubbing Free RAM 0xffc00000 -> 
0xdefb0000: .............................done.

On 64bit the scrubber goes up, but on 32bit it goes down.
Is this behaviour expected?
