Xen devel - Oct 2007 - [PATCH][x86-PAE] Avoid overflow in xc_domain_dumpcore_via_callback()

Hi.

On x86-PAE systems, guest domains can have memory larger
than 4GB.
When trying to get xendump of such a guest, nr_pages * PAGE_SIZE
exceeds 2^32, so "filesz" is not calculated properly
in xc_domain_dumpcore_via_callback().
As a result, the crash utility cannot access to the
string table section and cannot read the dumpfile.

Attached patch fixes this bug.


Thanks,
Daisuke Nishimura.
