Hi Barry,
I love your patch! Perhaps something to improve:
[auto build test WARNING on arm64/for-next/core]
[also build test WARNING on linus/master v5.7]
[cannot apply to next-20200602]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
url: https://github.com/0day-ci/linux/commits/Barry-Song/support-per-numa-CMA-for-ARM-server/20200603-104821
base: https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core
config: i386-randconfig-s002-20200602 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-13) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.1-244-g0ee050a8-dirty
# save the attached .config to linux build tree
make W=1 C=1 ARCH=i386 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
If you fix the issue, kindly add following tag as appropriate
Reported-by: kbuild test robot <lkp@intel.com>
sparse warnings: (new ones prefixed by >>)
>> kernel/dma/contiguous.c:40:12: sparse: sparse: symbol 'dma_contiguous_pernuma_area' was not declared. Should it be static?
>> kernel/dma/contiguous.c:278:50: sparse: sparse: invalid access below 'dma_contiguous_pernuma_area' (-4 4)
Please review and possibly fold the followup patch.
