Fix dumping in kdump format with non-aligned memory Hi, dump.c:get_next_page expects GuestPhysBlock to be page-aligned, and crashes over memory regions such as "tpm-crb-cmd". Teach it to handle non-aligned regions too, by using a caller pre-allocated filled up page as necessary. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2120480 v2: - drop some unnecessary changes in the first patch - use pre-allocated caller memory, instead of allocating in get_next_page() - fix some comment
