Pull arm64 fixes from Will Deacon:
 "Three arm64 fixes.

  The main one is a fix to the way in which we evaluate the macro
  arguments to our uaccess routines, which we _think_ might be the root
  cause behind some unkillable tasks we've seen in the Android arm64 CI
  farm (testing is ongoing). In any case, it's worth fixing.

  Other than that, we've toned down an over-zealous VM_BUG_ON() and
  fixed ftrace stack unwinding in a bunch of cases.

  Summary:

   - Evaluate uaccess macro arguments outside of the critical section

   - Tighten up VM_BUG_ON() in pmd_populate_kernel() to avoid false positive

   - Fix ftrace stack unwinding using HAVE_FUNCTION_GRAPH_RET_ADDR_PTR"
