With the following two patches, I was able to produce a dump even with high dump levels (-d17 and -d31). Needless to say, this can reduce the size of Dom0 dumps considerably. Changes in v2: * Call get_machdep_info() after cache_init(), so it can use readmem(VADDR, ...) This now works for me after reverting commit ebe2fa3a.
