Subject: [PATCH 1/2]: Powerpc: Fix EHCA driver on relocatable kernel
Date: Thu, 19 Aug 2010 23:08:09 -0500 [thread overview]
Message-ID: <20100820040809.GS16505@us.ibm.com> (raw)
Some modules (like eHCA) want to map all of kernel memory, for this to
work with a relocated kernel, we need to export kernstart_addr so
modules can use PHYSICAL_START and memstart_addr so they could use
MEMORY_START. Note that the 32bit code already exports these symbols.
