Recent versions of objcopy (e.g. from Fedora 37) complain:

Seems like we can silence these warnings by properly specifying
program headers in the linker script.

Applied to kvm-x86 next, thanks!
Thanks for picking it up!
On the topic of annoying warnings, this one is also quite annoying:
ld: warning: setjmp64.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
I thought "-z noexecstack" would make it go away, but either I'm wrong or I'm not
getting the flag set in the right place.
I never saw that warning here before, but I'm currently also still using an
older version of GCC and binutils here since my development machine is still
using RHEL 8 ...
Anyway, does this happen for the normal builds, or for the efi builds? I can
see a .note.GNU-stack entry in x86/efi/elf_x86_64_efi.lds ... maybe we need
something similar in x86/flat.lds ?
