From db6a5cef7f474a5bad476a31f4e4c69a69fab8b1 Mon Sep 17 00:00:00 2001 From: Satyam Sharma Date: Tue, 2 Oct 2007 13:39:45 -0700 Subject: [PATCH] [IA64] tree-wide: Misc __cpu{initdata, init, exit} annotations * palinfo.c: palinfo_cpu_notifier is a CPU hotplug notifier_block, and can be marked __cpuinitdata, and the callback function palinfo_cpu_callback() itself can be marked __cpuinit. create_palinfo_proc_entries() is only called from __cpuinit callback or general __init code, therefore a candidate for __cpuinit itself. remove_palinfo_proc_entries() is only called from __cpuinit callback or general __exit code, therefore a candidate for __cpuexit. * salinfo.c: The CPU hotplug notifier_block can be __cpuinitdata. The callback salinfo_cpu_callback() is incorrectly marked __devinit -- it must be __cpuinit instead. * topology.c: cache_sysfs_init() is only called at device_initcall() time so marking it as __cpuinit is wrong and wasteful. It should be unconditionally __init. Also cleanup reference to hotplug notifier callback function from this function and replace with cache_add_dev(), which could also enable us to use other tricks to replace __cpuinit{data} annotations, as recently discussed on this list. cache_shared_cpu_map_setup() is only ever called from __cpuinit-marked functions hence both its definitions (SMP or !SMP) are candidates for __cpuinit itself. Also all_cpu_cache_info can be __cpuinitdata because only referenced from __cpuinit code.
