Merge tag 'objtool_urgent_for_v5.15_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull objtool fixes from Borislav Petkov:

 - Remove an extra section.len member in favour of section.sh_size

 - Align .altinstructions section creation with the kernel's by creating
   them with entry size of 0

 - Fix objtool to convert a reloc symbol to a section offset and not to
   not warn about not knowing how

* tag 'objtool_urgent_for_v5.15_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  objtool: Remove redundant 'len' field from struct section
  objtool: Make .altinstructions section entry size consistent
  objtool: Remove reloc symbol type checks in get_alt_entry()
