commit: 17229c19e5bf0b5dc8b68dc4ca4e7012e7da4747 [4620/4884] mips: remove extraneous asm-generic/iomap.h include
config: mips-allnoconfig (https://download.01.org/0day-ci/archive/20231205/202312051917.ldwRetjX-lkp@intel.com/config)
compiler: clang version 17.0.0 (https://github.com/llvm/llvm-project.git 4a5ac14ee968ff0ad5d2cc1ffa0299048db4c88a)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20231205/202312051917.ldwRetjX-lkp@intel.com/reproduce)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp@intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202312051917.ldwRetjX-lkp@intel.com/
Note: the linux-next/master HEAD 0f5f12ac05f36f117e793656c3f560625e927f1b builds fine.
It may have been fixed somewhere.

This patch depends on the asm-generic/io.h cleanup series by
Jiaxun Yang and Baoquan He, which I have in my asm-generic
tree.
I've added my patch on top now, as it fits the general idea,
so this can be dropped from -mm (and not merged into the mips
tree).
