Subject: [PATCH 0/3] Add __ioread32_copy() and use it
Date: Wed, 16 Sep 2015 04:55:46 +0200	[thread overview]
Message-ID: <20150916025546.GE1747@two.firstfloor.org> (raw)

Compiler.

> LTO enabled?

Yes it's for LTO.  The optimization allows the compiler to drop unused
functions, which is very popular with users (a lot use it to get smaller
kernel images)
