Build results: total: 172 pass: 170 fail: 2 Failed builds: powerpc:defconfig powerpc:ppc6xx_defconfig Qemu test results: total: 315 pass: 315 fail: 0
Same build error as with v4.4.y, plus:
arch/powerpc/platforms/pseries/hotplug-memory.c: In function ‘dlpar_memory’: arch/powerpc/platforms/pseries/hotplug-memory.c:782:9: error: ‘rc’ may be used uninitialized in this function
which I completely fail to understand. It doesn't seeem to affect any other kernel version, and it looks like it is another compiler bug. I'll see if I can find out how to avoid it (other than reverting to an older version of gcc). Not a concern for now.
The problem seems to be related to dependencies. It is addressed upstream with commit 2b800f7c0c6c ("powerpc/cell: Drop select of MEMORY_HOTPLUG"). After this patch is applied, MEMORY_HOTPLUG is no longer enabled with powerpc:defconfig, and the problem is no longer seen.
Copying Michael to see if there is any concern about having this patch applied to v4.9.y.
