From: Tim Abbott Date: Tue, 23 Jun 2009 23:59:36 +0000 (-0400) Subject: Add new __init_task_data macro to be used in arch init_task.c files. X-Git-Tag: firefly_0821_release~13503^2~5 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=857eceebd2803c9a3459f784acf45e5266921e4d;p=firefly-linux-kernel-4.4.55.git Add new __init_task_data macro to be used in arch init_task.c files. This patch is preparation for replacing most ".data.init_task" 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".
