Subject: [PATCH 0/6] x86: Clean ups after minimum support compiler version
 bump

Hi x86 folks,

Here is a small series of clean ups that I noticed after PeterZ made a
comment about '-mskip-rax-setup' being supported with all compiler
versions that x86 requires to build (GCC 8.1+ and LLVM 15+). This has
seen a build with GCC 8, GCC 15, LLVM 15, and LLVM 21.

Nathan Chancellor (6):
      x86/build: Remove cc-option for GCC retpoline flags
      x86/build: Remove cc-option from stack alignment flags
      x86/build: Clean up stack alignment flags in CC_FLAGS_FPU
      x86/build: Remove cc-option from -mno-fp-ret-in-387
      x86/build: Remove cc-option from -mskip-rax-setup
      x86/Kconfig: Clean up LLVM version checks in IBT configurations
