The kernel is aligned at SEGMENT_SIZE and this is the size populated in the PE
headers:
arch/arm64/kernel/efi-header.S: .long SEGMENT_ALIGN // SectionAlignment
EFI_KIMG_ALIGN is defined as: (SEGMENT_ALIGN > THREAD_ALIGN ? SEGMENT_ALIGN :
THREAD_ALIGN)
So it depends on THREAD_ALIGN. On newer builds this message started to appear
even though the loader is taking into account the PE header (which is stating
SEGMENT_ALIGN).
