Subject: ia64 broken by transparent huge pages - other arches too?
Date: Fri, 14 Jan 2011 09:50:45 -0800 [thread overview]
Message-ID: <4d308cf5394566ccc@agluck-desktop.sc.intel.com> (raw)
Didn't Andrew make some rash promise at kernel summit about stopping
eating if "-mm" wasn't included in linux-next by the end of November?
Must be getting pretty hungry by now.
The transparent huge page code just arrived in the merge window
without having been in linux-next. I see this error when trying
to build for ia64 from Linus' tree this morning:

Looks like arch/*/include/pgtable.h needs to define __pmd() but only x86
was blessed with it.
