Subject: Redefine {un}register_hotcpu_notifier() !HOTPLUG_CPU stubs
X-Git-Tag: v2.6.24-rc1~335
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=761bb431908e84d1793c5eb6c2ae2cc4926bed3e;p=pandora-kernel.git

Redefine {un}register_hotcpu_notifier() !HOTPLUG_CPU stubs

The return of the present "do {} while" based stub definition of
register_hotcpu_notifier() cannot be checked.  This makes the stub
asymmetric w.r.t.  the real HOTPLUG_CPU=y implementation that is
int-returning.  So let us redefine this to be consistent with the full
version.  Also do the same for unregister_hotcpu_notifier().

We cannot define these as static inline functions due to an existing GCC
bug (#33172).  So define as macros that return appropriately instead (int
'0' for the register_hotcpu_notifier case and void for
unregister_hotcpu_notifier).
