Subject: Add the new names of RETPOLINE, CPU_SRSO, SLS
X-Git-Tag: v0.6.10~63
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=86b67f39d3846fddb4419689c0e2d3ff35876cc5;hp=9d1c4cf0068065842f838125245ead146bf247b6;p=kconfig-hardened-check.git

Add the new names of RETPOLINE, CPU_SRSO, SLS

Since Linux v6.9 they are renamed:
  RETPOLINE -> MITIGATION_RETPOLINE
  CPU_SRSO -> MITIGATION_SRSO
  SLS -> MITIGATION_SLS

Refers to #127, #117
