Subject: [PATCH core/percpu REPOST] linker script: add missing VMLINUX_SYMBOL

The newly added PERCPU_*() macros define and use __per_cpu_load but
VMLINUX_SYMBOL() was missing from usages causing build failures on
archs where linker visible symbol is different from C symbols
(e.g. blackfin).

Just realized this was reply to a private mail.  Restoring cc list
and resending.

Thanks.
