The patch titled
um: fix errno usage
has been removed from the -mm tree. Its filename was
uml-fix-errno-usage.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: um: fix errno usage
From: Paolo 'Blaisorblade' Giarrusso <blaisorblade@xxxxxxxx>
Avoid reusing userspace errno twice - it can be cleared by libc code
everywhere (in particular printk() does clear it in my setup).
