[PATCH v3 0/2] x86/tsx: Improve handling of the tsx= kernel parameter

[Petr Tesarik <ptesarik@suse.com>]

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

As a side note, it was not necessary to defer the handling of
tsx=auto. Contrary to Pawan's claim, cpu_set_bug_bits() is called
from setup_arch() via early_cpu_init() and early_identify_cpu() before
parse_early_param(). But it is a nice cleanup, nevertheless, and I
learned something about parsing the command line. Cf. the NAK here:
https://lore.kernel.org/all/20251009185134.fb4evjrk76rwxv37@desk/

Changes from v2:
* compile-time initialization with the configured default
* defer tsx=auto handling to tsx_init()
* add more detail to the commit message

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()
