commit: 4eeef098b43242ed145c83fba9989d586d707589 powerpc/44x: Remove STDBINUTILS kconfig option
date: 4 months ago
config: powerpc-randconfig-r012-20210609 (attached as .config)
compiler: powerpc-linux-gcc (GCC) 9.3.0
That's a BTRFS issue, and not directly linked to the above mentioned commit. Before that commit the
problem was already present.
Problem is that with 256k PAGE_SIZE, following BUILD_BUG() pops up:
BUILD_BUG_ON((BTRFS_MAX_COMPRESSED % PAGE_SIZE) != 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 linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
