Nathan Chancellor 33806e7cb8 x86/Kconfig: Drop check for -mabi=ms for CONFIG_EFI_STUB ... A recent change in LLVM made CONFIG_EFI_STUB unselectable because it no longer pretends to support -mabi=ms, breaking the dependency in Kconfig. Lack of CONFIG_EFI_STUB can prevent kernels from booting via EFI in certain circumstances. This check was added by 8f24f8c2fc ("efi/libstub: Annotate firmware routines as __efiapi") to ensure that __attribute__((ms_abi)) was available, as -mabi=ms is not actually used in any cflags. According to the GCC documentation, this attribute has been supported since GCC 4.4.7. The kernel currently requires GCC 5.1 so this check is not necessary; even when that change landed in 5.6, the kernel required GCC 4.9 so it was unnecessary then as well. Clang supports __attribute__((ms_abi)) for all versions that are supported for building the kernel so no additional check is needed. Remove the 'depends on' line altogether to allow CONFIG_EFI_STUB to be selected when CONFIG_EFI is enabled, regardless of compiler.
