That removes some relocations that otherwise appear due to the usage of the start and __efi64_mb2_start symbols in the multiboot2 header. No functional change intended. Signed-off-by: Roger Pau Monné Reviewed-by: Jan Beulich --- We could also place the multiboot header in it's own isolated section and skip such section for relocations generation in mkreloc, but it seems best to just remove the code if it's unused. --- xen/arch/x86/xen.lds.S | 3 +++ 1 file changed, 3 insertions(+) diff --git a/xen/arch/x86/xen.lds.S b/xen/arch/x86/xen.lds.S index d4dd6434c466..ad908539f38a 100644 --- a/xen/arch/x86/xen.lds.S +++ b/xen/arch/x86/xen.lds.S @@ -61,6 +61,9 @@ SECTIONS __image_base__ = .; #else . = __image_base__; + /DISCARD/ : { + *(.text.header) + } #endif #if 0
