Subject: [PATCH] [PATCH] fix vm_events_fold_cpu() build breakage
fix vm_events_fold_cpu() build breakage
2.6.20-rc1 does not build properly if CONFIG_VM_EVENT_COUNTERS is set
and CONFIG_HOTPLUG is unset:
CC init/version.o
LD init/built-in.o
LD .tmp_vmlinux1
mm/built-in.o: In function `page_alloc_cpu_notify':
page_alloc.c:(.text+0x56eb): undefined reference to `vm_events_fold_cpu'
make: *** [.tmp_vmlinux1] Error 1
[akpm@osdl.org: cleanup]
