OK, seems reasonable. Eric Biederman solved this by having NOTE/ENDNOTE (or something like that) in his "bzImage with ELF header" patch, but I don't remember it being used in any way which is incompatible with using a CPP macro.

I can't find that patch, does NOTE/ENDNOTE just do the push/pop .note
section?

That would solve the problem with the first argument of the macro being
a string but the final argument could still be for .asciz note contents.

It looks like:

.macro note name, type
.balign 4
.int 2f - 1f # n_namesz
.int 4f - 3f # n_descsz
.int \type # n_type
.balign 4
1: .asciz "\name"
2: .balign 4
3:
.endm
.macro enote
4: .balign 4
.endm

so it allows you to put arbitrary stuff in the desc part of the note. The downside is that its a little more cumbersome syntactically for the common case.
