Trying to use makedumpfile on a Xen Dom0 ELF file currently fails, but there
are in fact only a few missing pieces. 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.

Petr Tesarik (2):
  Earlier initialization of dom0_mapnr
  Get Dom0 max_pfn using pfn_mfn_frame_list if max_pfn unavailable
