Subject: [RFC v2 4/7] asm/sections: add a generic push_section_tbl()
Date: Fri, 19 Feb 2016 05:45:56 -0800 [thread overview]
Message-ID: <1455889559-9428-5-git-send-email-mcgrof@kernel.org> (raw)
In-Reply-To: <1455889559-9428-1-git-send-email-mcgrof@kernel.org>
With a generic linker tables solution in place we
need a general asm solution for declaring entries
with asm. The first easy target is to cover the C
asm declarations, guard the header file for now
and define a first generic entry push_section_tbl()
to be used later for custom linker table annotations.
