[Xen-devel] user mode access to kernel memory

["Jan Beulich" <JBeulich@xxxxxxxxxx>]

Tools like crash want to read /proc/mem to get access to RAM. This isn't
allowed under Xen due to the physical/machine address spaces being
distinct. I wonder, however, why this also isn't permitted through
privcmd (or really, why direct_remap_pfn_range() rejects DOMID_SELF,
but permits the resolved domain ID to be passed).

Thanks, Jan
