The patch titled
intel_cacheinfo: Misc section annotation fixes / cleanups
has been removed from the -mm tree. Its filename was
intel_cacheinfo-misc-section-annotation-fixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: intel_cacheinfo: Misc section annotation fixes / cleanups
From: Satyam Sharma <satyam@xxxxxxxxxxxxx>
cache_sysfs_init() is only ever called at device_initcall() time. Marking it
__cpuinit is quite wrong, and wasteful when HOTPLUG_CPU=y. It must be __init.
cache_shared_cpu_map_setup() and cache_remove_shared_cpu_map(), OTOH, are
functions called from another function that is __cpuinit. But the !CONFIG_SMP
empty-body stubs of these functions are unconditionally marked __init, which
is actively wrong, and will lead to oops. But we never saw this oops, because
they always managed to get inlined in their callsites, by virtue of being
empty-body stubs! They should still be __cpuinit, of course.
assocs[], levels[] and types[] are only referenced from function that is
__cpuinit. So these are candidates for being marked __cpuinitdata.
