Subject: NOUPSTREAM: ANDROID: kernel: Core kernel related vendor hooks

  - Add the hook to apply vendor's performance tune for owner
    of rwsem.

  - Add the hook for the waiter list of rwsem to allow
    vendor perform waiting queue enhancement

  - ANDROID_VENDOR_DATA added to rw_semaphore

[CPNOTE: 27/05/21] Lee: Vendor related code - maintain forever

Squash:
  NOUPSTREAM: ANDROID: workqueue: add vendor hook for wq lockup information
  NOUPSTREAM: ANDROID: printk: add vendor hook for console flush
  NOUPSTREAM: ANDROID: vendor_hooks: Add hook for jiffies updates
  NOUPSTREAM: ANDROID: sched_clock: Add vendor hook to print epoch values
  NOUPSTREAM: ANDROID: sched/cpuset: Add vendor hook to change tasks affinity
  NOUPSTREAM: ANDROID: tracing: Add restricted vendor hooks for preemptirq events
  NOUPSTREAM: ANDROID: ftrace: vendor hook for ftrace dump on oops
  NOUPSTREAM: ANDROID: cgroup: Add vendor hook to the cgroup
  NOUPSTREAM: ANDROID: Add vendor hooks when syscall prctl finished
  NOUPSTREAM: ANDROID: timer: Add vendor hook for timer calc index
  ANDROID: cgroup: Add android_rvh_cgroup_force_kthread_migration
  ANDROID: kernel: Add restricted vendor hook in creds
  ANDROID: module: Add vendor hook
  ANDROID: syscall_check: add vendor hook for bpf syscall
  ANDROID: Re-apply vendor hooks for information of blocked tasks
  ANDROID: Re-apply vendor hooks for rt_mutex information of blocked tasks
  Revert "ANDROID: timer: Add vendor hook for timer calc index"
