Subject: [PATCH 1/5] V5 ia64 SPARSEMEM - Kconfig and Makefile
Date: Tue, 04 Oct 2005 19:13:37 +0000 [thread overview]
Message-ID: <20051004191337.GQ25483@localhost.localdomain> (raw)
The patch modifies the Kconfig file to introduce the new memory model
options and other related SPARSEMEM changes. There is also a minor change
in the Makefile.
