Subject: Shadow code printing adjustments.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14891
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/%22bookmarks://%22Dat/%22http:/www.example.com/cgi/%22https:/%22bookmarks:/%22Dat?a=commitdiff_plain;h=02f2086e5477b9fe0456f969d64894ee05a8f707;p=xen.git

Shadow code printing adjustments.

Messages prior to BUG() should always be displayed, not just when
DEBUG_TRACE_DUMP is defined (which by default it isn't). Convert them
from SHADOW_PRINTK() to SHADOW_ERROR().
