Some virtio device drivers (9p) need to translate high virtual addresses
to physical addresses, which are inserted into the virtqueue for
processing by userspace.
This patch exports the kmap_to_page symbol, so that the affected drivers
can be compiled as modules.

Hi,
we are currently implementing a suspend to RAM like low
().
This is often because armpmu_register lacks a __init
annotation or the annotation of armpmu_init is wrong.
Just drop the __init marking on armpmu_init() because
armpmu_register() no longer has an __init marking.
