Hi,
The commit ae7486a2b734ee03 (iwlwifi: fix Kconfig issues) in 3.17-rc1
breaks iwlwifi for kernels built without support for modules
(CONFIG_MODULES=n).
It changes the dependencies of IWLDVM and IWLMVM from
depends on IWLWIFI
to
depends on m
(while enclosing the whole set of options in 'if IWLWIFI').
Why that dependency on 'm' for apparently mandatory feature of the driver
(without DVM and MVM, Kconfig comment says
"WARNING: iwlwifi is useless without IWLDVM or IWLMVM"
Up until 3.16 it was very well possible to operate iwlwifi built-in
in a kernel without support for modules, either by building firmware
into the kernel, or as needed re-binding the driver to the PCI device
once filesystems were mounted.
Removing those two 'depend on m' iwlwifi works fine for a 7260
wireless card.

I know - you are not the first to report that - I have already 2
versions of the exact same patch fixing this.
But I am currently travelling and I'll handle later.
