xieliujie 09f3b2441a ANDROID: vendor_hooks: Add hooks for oem percpu-rwsem optimaton ...

Recently we have discovered many lag issues caused by percpu_rwsem
lock-holding tasks not being scheduled for a long time. we need to
identify them and provide appropriate scheduling protection in our
oem scheduler.
To support this, we add one hook below:
	trace_android_vh_percpu_rwsem_wq_add
