Linus Torvalds ef6900acc8 Tracing fixes for 5.10-rc6
- Use correct timestamp variable for ring buffer write stamp update
  - Fix up before stamp and write stamp when crossing ring buffer sub
    buffers
  - Keep a zero delta in ring buffer in slow path if cmpxchg fails
  - Fix trace_printk static buffer for archs that care
  - Fix ftrace record accounting for ftrace ops with trampolines
  - Fix DYNAMIC_FTRACE_WITH_DIRECT_CALLS dependency
  - Remove WARN_ON in hwlat tracer that triggers on something that is OK
  - Make "my_tramp" trampoline in ftrace direct sample code global
  - Fixes in the bootconfig tool for better alignment management
