Hi all,
After merging the akpm-current tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
mm/memory_hotplug.c: In function 'move_pfn_range_to_zone':
mm/memory_hotplug.c:772:24: error: 'ZONE_DEVICE' undeclared (first use in this function)
772 | if (zone_idx(zone) == ZONE_DEVICE) {
| ^~~~~~~~~~~
Caused by commit
e821cf25cfee ("mm: teach pfn_to_online_page() about ZONE_DEVICE section collisions")
I applied the patch from Randy Dunlap for today.
That, however, lead to this warning:
mm/memory_hotplug.c:730:13: warning: 'section_taint_zone_device' defined but not used [-Wunused-function]
730 | static void section_taint_zone_device(unsigned long pfn)
| ^~~~~~~~~~~~~~~~~~~~~~~~~

I sent this one as an alternate:

I have used that today instead of Randy's patch, thanks.
