Hmm, if CONFIG_DEBUG_BOOT_PARAMS is not set, then kexec-tools should fail getting efi_info, so I will fix kexec-tools patch about this. Also CONFIG_EFI_RUNTIME_MAP should select CONFIG_DEBUG_BOOT_PARAMS. In future will try to move the boot params data out of debugfs. > > I see a bunch of section mismatch warnings, > > WARNING: arch/x86/platform/efi/built-in.o(.text+0xd1e): Section mismatch in reference from the function efi_map_regions_fixed() to the function .init.text:efi_map_region_fixed() > The function efi_map_regions_fixed() references > the function __init efi_map_region_fixed(). > This is often because efi_map_regions_fixed lacks a __init > annotation or the annotation of efi_map_region_fixed is wrong. > > WARNING: arch/x86/platform/efi/built-in.o(.text+0xd2a): Section mismatch in reference from the function efi_map_regions_fixed() to the variable .init.data:efi_phys > The function efi_map_regions_fixed() references > the variable __initdata efi_phys. > This is often because efi_map_regions_fixed lacks a __initdata > annotation or the annotation of efi_phys is wrong. > > WARNING: arch/x86/platform/built-in.o(.text+0xd1e): Section mismatch in reference from the function efi_map_regions_fixed() to the function .init.text:efi_map_region_fixed() > The function efi_map_regions_fixed() references > the function __init efi_map_region_fixed(). > This is often because efi_map_regions_fixed lacks a __init > annotation or the annotation of efi_map_region_fixed is wrong. > > WARNING: arch/x86/platform/built-in.o(.text+0xd2a): Section mismatch in reference from the function efi_map_regions_fixed() to the variable .init.data:efi_phys > The function efi_map_regions_fixed() references > the variable __initdata efi_phys. > This is often because efi_map_regions_fixed lacks a __initdata > annotation or the annotation of efi_phys is wrong. > > WARNING: arch/x86/built-in.o(.text+0x7c357): Section mismatch in reference from the function parse_efi_setup() to the function .init.text:early_memremap() > The function parse_efi_setup() references > the function __init early_memremap(). > This is often because parse_efi_setup lacks a __init > annotation or the annotation of early_memremap is wrong. > > WARNING: arch/x86/built-in.o(.text+0x7c390): Section mismatch in reference from the function parse_efi_setup() to the function .init.text:early_iounmap() > The function parse_efi_setup() references > the function __init early_iounmap(). > This is often because parse_efi_setup lacks a __init > annotation or the annotation of early_iounmap is wrong. > > WARNING: arch/x86/built-in.o(.text+0x7c5ce): Section mismatch in reference from the function efi_map_regions_fixed() to the function .init.text:efi_map_region_fixed() > The function efi_map_regions_fixed() references > the function __init efi_map_region_fixed(). > This is often because efi_map_regions_fixed lacks a __init > annotation or the annotation of efi_map_region_fixed is wrong. > > WARNING: arch/x86/built-in.o(.text+0x7c5da): Section mismatch in reference from the function efi_map_regions_fixed() to the variable .init.data:vdso32_sysenter_end > The function efi_map_regions_fixed() references > the variable __initdata vdso32_sysenter_end. > This is often because efi_map_regions_fixed lacks a __initdata > annotation or the annotation of vdso32_sysenter_end is wrong.
