Subject: [PATCH 0/2] x86/e820: Use pr_debug to avoid spamming dmesg log with
 debug messages

e820 emits quite some debug messages to the dmesg log. Let's restrict
this to cases where the debug output is actually requested. Switch to
pr_debug() for this purpose and make sure by checking the return code
that pr_cont() is only called if applicable. This would currently fail
if dynamic debugging is enabled because dynamic_pr_debug() has no
return value. So let's change this first.
