SubjectRe: [PATCH 3/8] parisc: turn GET_IOC into an inline function
Hi Christoph,

I love your patch! Yet something to improve:

[auto build test ERROR on hp-parisc/for-next]
[also build test ERROR on v5.0-rc2 next-20190114]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/Christoph-Hellwig/parisc-don-t-include-asm-cacheflush-h-in-asm-dma-mapping-h/20190115-034634
base: https://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git for-next
config: parisc-b180_defconfig (attached as .config)
compiler: hppa-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
GCC_VERSION=7.2.0 make.cross ARCH=parisc

All errors (new ones prefixed by >>):

In file included from drivers/parisc/hppb.c:26:0:
