The patch titled
ehca_irq: misc cpuinit section annotations and #ifdef cleanups
has been removed from the -mm tree. Its filename was
ehca_irq-misc-cpuinit-section-annotations-and-ifdef-cleanups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: ehca_irq: misc cpuinit section annotations and #ifdef cleanups
From: Satyam Sharma <satyam@xxxxxxxxxxxxx>
* Replace {un}register_cpu_notifier with {un}register_hotcpu_notifier
thereby losing a couple of #ifdef HOTPLUG_CPU pairs.
* Move comp_pool_callback_nb declaration to below that of callback
function so that initialization of .notifier_call and .priority can
occur at build time itself and not runtime.
* Mark the notifier_block (and callback function, and another static
function used by it) as __cpuinit{data} for the sake of consistency
and remove enclosing #ifdef. (This may increase size for modular
build of this module, however, because these are no longer dropped
unconditionally now.)
