The patch titled
markers: define the linker macro EXTRA_RWDATA
has been removed from the -mm tree. Its filename was
markers-define-the-linker-macro-extra_rwdata.patch
This patch was dropped because an updated version will be merged
------------------------------------------------------
Subject: markers: define the linker macro EXTRA_RWDATA
From: Mathieu Desnoyers <mathieu.desnoyers@xxxxxxxxxx>
Defines the linker macro EXTRA_RWDATA for the marker data section. It puts
the marker data in a separate section that will not pollute the normal .data
section, which minimize the cache impact. Markers need such a special section
because they define a lot of spreaded and small data structures at multiple
sites.
This patch also creates the __markers_strings section (ro marker strings) and
makes sure the __markers section is aligned by putting it before the
__ksymtab_strings (not after).
