The patch titled
um: mark both consoles as CON_ANYTIME
has been removed from the -mm tree. Its filename was
uml-mark-both-consoles-as-con_anytime.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: um: mark both consoles as CON_ANYTIME
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
Since both UML consoles do not use percpu variables, they may be called when
the cpu is still offline, and they may be marked CON_ANYTIME (this is
documented in kernel/printk.c, grep for CON_ANYTIME to find mentions of this).
Works well in testing done with lock debug enabled, should be safe but is not
needed for next release.
This would probably help also stderr_console.c, but this is yet to test.
