Subject: [PATCH 3.11 038/208] scripts/link-vmlinux.sh: only filter kernel symbols for arm

3.11.10.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ming Lei <tom.leiming@...il.com>

commit 7122c3e9154b5d9a7422f68f02d8acf050fad2b0 upstream.

Actually CONFIG_PAGE_OFFSET isn't same with PAGE_OFFSET, so
it isn't easy to figue out PAGE_OFFSET defined in header
file from scripts.

Because CONFIG_PAGE_OFFSET may not be defined in some ARCHs(
64bit ARCH), or defined as bogus value in !MMU case, so
this patch only applys the filter on ARM when CONFIG_PAGE_OFFSET
is defined as the original problem is only on ARM.
