that's a gcc bug; probably arm specific even?

It's gcc 4.01... the kautobuild folk are going to try gcc 4.04 instead.

Actually, given that it also appears with gcc 3.3, I'd like to request
that the change (along with all the other const __devinitdata's) are
backed out.
The comments I'm hearing about gcc 4.1 on ARM indicate that it's a case
of "there be big beasts there, don't touch with a barge pole". To quote
some comments about gcc 4.1 on ARM:
"yeah, 4.1 is quite bad on arm. it's supposed to have all the EABI bits,
but it can't even build itself without ICEing and segfaulting left right
and center"
"the debian arm failures with gcc 4.1 are just scary. the current gcc
4.1s miscompile even very basic for/while loops"
which probably leaves ARM folk with a very narrow set of working gcc
versions.
So, I've no idea at present which gcc version we should be considering
nominating as "the sole gcc version the kernel supports".

ok that's entirely reasonable and I'm perfectly ok with that.

Just a data point...
My ARM GCCs are configured for the default arm-linux ABI,
not the EABI, and gcc-4.0.3 and gcc-4.1 both appear to be
solid for user-space code; they also bootstrap themselves
(on an ARM) just fine. I haven't used them for kernels however.
On the other hand, gcc-3.3.6 and gcc-3.4.6 both require several
add-on patches to fix incorrect code generation, and even then
there are a couple of known unfixed bugs (PR25133 and PR26463 in
particular; PR25133 can be worked around but PR26463 scares me).
