Subject: [PATCH 5/6] Add new READ_MOSTLY_DATA(align) linker script macro.
Date: Thu, 30 Apr 2009 15:32:35 -0400 [thread overview]
Message-ID: <1241119956-31453-6-git-send-email-tabbott@mit.edu> (raw)
In-Reply-To: <1241119956-31453-5-git-send-email-tabbott@mit.edu>
This patch is preparation for replacing most ".data.read_mostly" in
the kernel with macros, so that the section name can later be changed
without having to touch a lot of the kernel.
The long-term goal here is to be able to change the kernel's magic
section names to those that are compatible with -ffunction-sections
-fdata-sections. This requires renaming all magic sections with names
of the form ".data.foo".
