[PATCH v3 0/4] PF: Add handling for new adverse event thresholds

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

We want to extend our macro-based KLV list definitions with new
information about the version from which given KLV is supported.

Instead of using magic version like 0.0.0 for legacy KLVs, add
utility IF_ARGS macro that can be used in code generators to emit
different code based on the presence of any additional arguments.

This series cherry-picks one patch from the EGS series [1] and
can be merged separately.

v1: https://patchwork.freedesktop.org/series/158874/#rev1
v2: https://patchwork.freedesktop.org/series/158874/#rev2
    new patch with GUC_FIRMWARE_VER_AT_LEAST macro
v3: alternate implementation of IF_ARGS macro for older GCC
    as kernel test robot reported errors on GCC 8.5.0 and
    same errors were seen locally on 9.5.0 but not on 10.1.0
