CA-123096: Disable apic-v for all hosts
Nuke unreferenced patch.  It is quite broken

--HG--
extra : rebase_source : a7bd0af897f3dfeafd570fba643a31ffff05a7fa
Fold 'disable-apic-v' into 'tweak-cmline-defaults'
More debugging in check_lock
CA-123148 - Remove debugging.  It was fixed by previous race condition fix
Merge by b2bmerge!
Remove double newline.  This removes a spurious '#012' from appearing via syslog
Fix comments.  They were wrong.  (Noticed while discussing one of these bugs on xen-devel)
