From: Thomas Zimmermann Date: Fri, 12 Jan 2024 09:44:38 +0000 (+0100) Subject: x86/efi: Implement arch_ima_efi_boot_mode() in source file X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=785ddc8b6bebd958a5b6fb7b6b4aa6584c2f0cb2;p=linux.git x86/efi: Implement arch_ima_efi_boot_mode() in source file The x86 implementation of arch_ima_efi_boot_mode() uses the global boot_param state. Move it into a source file to clean up the header. Avoid potential rebuilds of unrelated source files if boot_params changes.
