Hi Nishanth,

[auto build test results on v4.3-rc3 -- if it's inappropriate base, please ignore]

config: arm64-allmodconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

All error/warnings (new ones prefixed by >>):

>> drivers/block/nvme-core.c:45:23: fatal error: asm/iommu.h: No such file or directory
    #include <asm/iommu.h>
                          ^
