I reset my build tree to commit 9d67df654092 ("Merge remote-tracking
branch 'block/for-next'") and the build failed with:
ERROR: ".local_clock" [drivers/vhost/vhost_net.ko] undefined!
ERROR: ".local_clock" [drivers/misc/cxl/cxl.ko] undefined!
:-(
So I did a "make mrproper" and did the build again.
That built correctly.
Then I reset the tree to commit b087ce990625 ("Merge remote-tracking
branch 'input/next'"), did a "make mrproper", "make ppc64_defconfig",
"make" and that built correctly. So I fast forwarded back to the block
tree merge and did "make ppc64_defconfig" and "make" and that failed
with:
ERROR: ".blk_queue_write_cache" [drivers/block/virtio_blk.ko] undefined!
ERROR: ".blk_queue_write_cache" [drivers/block/ps3disk.ko] undefined!
ERROR: ".blk_queue_write_cache" [drivers/block/nbd.ko] undefined!
Doing the revert made it build, then doing "reset --hard HEAD^" (i.e.
undoing the revert) also kept the build working.
These builds all have a separate object directory and are powerpc64le
hosted powerpc64be cross builds and use "make -j80".
