Subject: [for-linus][PATCH 0/6] tracing: Fixes for 5.14-rc4

Various tracing fixes:

- Fix NULL pointer dereference caused by an error path

- Give histogram calculation fields a size, otherwise it breaks synthetic
  creation based on them.

- Reject strings being used for number calculations.

- Fix recordmcount.pl warning on llvm building RISC-V allmodconfig

- Fix the draw_functrace.py script to handle the new trace output

- Fix warning of smp_processor_id() in preemptible code
