Hello,
Current hypervisor code/build produces an invalid binary when linked
with lld 8 (llvm linker). This is because lld 8 places orphaned sections
at the beginning of the output file, thus displacing the multiboot
headers.
In order to build a correct image with lld 8 make sure there are no
orphaned sections, and also add a build-time check to assert the
multiboot headers are present between the offset boundary given in the
specification.
Roger Pau Monne (4):
xz: use initconst for hypervisor build
x86/linker: use DECL_SECTION uniformly
x86/linker: add a reloc section to ELF binary
x86: check for multiboot{1,2} header presence
