memory-hotplug: suppress "Trying to free nonexistent resource <XXXXXXXXXXXXXXXX-YYYYYYYYYYYYYYYY>" warning
When our x86 box calls __remove_pages(), release_mem_region() shows many
warnings. And x86 box cannot unregister iomem_resource.
"Trying to free nonexistent resource <XXXXXXXXXXXXXXXX-YYYYYYYYYYYYYYYY>"
release_mem_region() has been changed to be called in each
PAGES_PER_SECTION by commit de7f0cba9678 ("memory hotplug: release
memory regions in PAGES_PER_SECTION chunks"). Because powerpc registers
iomem_resource in each PAGES_PER_SECTION chunk. But when I hot add
memory on x86 box, iomem_resource is register in each _CRS not
PAGES_PER_SECTION chunk. So x86 box unregisters iomem_resource.
The patch fixes the problem.
