drivers/gpu/drm/tegra/gem.c:144:10: error: implicit declaration of function
'vmap'; did you mean 'kmap'?
Hi Laurent,
First bad commit (maybe != root cause):
tree: git://linuxtv.org/pinchartl/media.git drm/du/compile-test
head: e5afcf496f9bd487419c7ee0c258da75d0d1dae6
commit: 38c621b82b0e47d9fd0ce837b3c0f8c5c8156727 [11/12] drm/tegra: Enable COMPILE_TEST on all architectures
config: parisc-allyesconfig (attached as .config)
compiler: hppa-linux-gcc (GCC) 10.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git remote add pinchartl-media git://linuxtv.org/pinchartl/media.git
git fetch --no-tags pinchartl-media drm/du/compile-test
git checkout 38c621b82b0e47d9fd0ce837b3c0f8c5c8156727
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-10.3.0 make.cross ARCH=parisc
If you fix the issue, kindly add following tag as appropriate
