This patchset changes synchronize_rcu to call_rcu in update_shadow.

Patch 1 enables the CFI sanitization for cfi.c and 
bypass __cfi_slowpath_diag.
It is the prerequisite for using call_rcu in cfi.c.

Patch 2 changes synchronize_rcu to call_rcu and
free old cfi shadow in rcu cb

Changes in v2:
 - Remove _run_cfi_check,add __nocfi to __cfi_slowpath_diag directly
 - Rename _cfi_shadow_free_rcu to free_shadow

Haibo Li (2):
  cfi: enable sanitize for cfi.c
  cfi: free old cfi shadow asynchronously
