Do we really need even more extra checks, and a function that is not
inlined anymore ?
virt_addr_valid() used to be pretty simple. Some
No functional change in this patch. This was done so that
the previous change (commit ac790d09885d ("powerpc/memhotplug:
Add add_pages override for PPC")) can be easily backported.

The of_iomap() function returns NULL on failure, it never returns

As far as I can tell, that is not needed, as long as every configuration
sets a specific -mcpu= option,
for_each_compatible_node() will automaitically increase and decrease
the refcount of the device_node object. There is no need to call
additional of_node_get(). It is better to keep the original meaning
of refcounting as there is no any new reference created.

In fsl_setup_msi_irqs(), we should use of_node_put() for the
refernece 'np' returned by of_parse_phandle() which increases
the refcount.
