Subject: mm: improve message in populate physmap when the domain is direct mapped
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=3f3a26badbe9e980c759e2246cb248ceef018968;p=people%2Fliuw%2Flibxenctrl-split%2Fxen.git

mm: improve message in populate physmap when the domain is direct mapped

The current domain and the domain pointed by the variable "d" are not
the same.

However, when it's not possible to get a reference on the page, the
target domain ID is not printed. This makes the message difficult to
understand.

Improve the message by printing the target domain ID.
