Subject: [PATCH 34/42] ACPICA: Events: Uses common_notify for address space handlers
ACPICA commit 5ea0fb75fdf1aa7c0aba067dfa4d5dc3a9279461
The address space handlers can be attached to not only Device but also
Processor/thermal_zone objects, so it is better to use their common
class 'CommonNotify' instead. Lv Zheng.
