Hi guys,

If I build an arm64 kernel, then simply hit make again without changing
anything, I find that efi-stub.o is rebuilt every time (with an annoying
warning too, but I think you already know about that):

Yep, I had noticed that as well. The reason is that it depends on
generated header files, which it shouldn't. There's already a patch
queued in Matt Fleming's tree for this:
https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/commit/?h=next&id=86b2eb8cdffda7eef07b1d6e5464491df1e86ee9

It sounds like that commit should actually be put into my 'urgent'
branch and sent to tip asap instead of being queued up for the next
merge window.

Objections?
