Hi Nishanth,

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

config: sparc64-allyesconfig (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=sparc64 

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

   drivers/block/nvme-core.c: In function 'nvme_configure_admin_queue':
>> drivers/block/nvme-core.c:1717:2: error: implicit declaration of function 'dma_get_page_shift' [-Werror=implicit-function-declaration]
     unsigned page_shift = dma_get_page_shift(dev->dev);
