Subject: [PATCH v2 0/2] x86/tsx: Improve handling of the tsx= kernel parameter

Parse the tsx= kernel parameter with early_param(), so it is not
reported as unknown.

Changes from v1:
* make tsx_ctrl_state local to tsx.c
* use early_param() instead of core_param()

Petr Tesarik (2):
  x86/tsx: Make tsx_ctrl_state static
  x86/tsx: Get the tsx= command line parameter with early_param()
