Subject: Remove DOM0_PHYSICAL_MEMORY_MAP dom0 op.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~16047^2~4
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/success//%22http:/www.example.com/cgi/success/?a=commitdiff_plain;h=25ea2bde5146aa375e215ff82915060b7141cef7;p=xen.git

Remove DOM0_PHYSICAL_MEMORY_MAP dom0 op.

The addition of the e820 style memory_op sub calls make this operation
obsolete.
