Xen devel - Sep 2006 - PATCH (ACM): keep binary stream aligned

Hi,

I am currently porting ACM to xen/ia64.
Because ia64 can''t handle unaligned accesses, the binary policy file
should be
aligned.  This patch fixes this issue.
(There is the same issue within xen/acm for dumping feature.  A patch will 
follow).

Tested on xen/ia64.

Tristan.

Great news Tristan!  We do not have ia64 systems available for testing but 
we are very interested in how your ACM port is going.

Thanks. Please submit the patch for creating the dump in the ACM (if you 
have one) as well.

I tried the tools/security patch on my laptop and it works fine on my x86 
Xen.

Please make sure the ''alignment-hole'' in the policy reference
is filled
deterministically (e.g., with \''0''). The same source policy
should always
yield the same binary policy.

Thanks
Reiner

Yes, that''s the reason why I have added a memset!
