parent[PATCH] powerpc: Fix database regression due to scheduler changes (diff)
[PATCH] Avoid use of uninitialised spinlock in EEH.
If the kernel supports both G5 and pSeries, and CONFIG_EEH is enabled, eeh_init() is (quite reasonably) never called when we boot on a G5. Yet eeh_check_failure() still gets called. We should avoid doing that if !eeh_subsystem_enabled. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
