The infiniband address handle can be triggered to resolve an ipv6
address in response to MAD packets, regardless of the ipv6
module being disabled via the kernel command line argument.
That will cause a call into the ipv6 routing code, which is not
initialized, and a conseguent oops.
This commit addresses the above issue replacing the direct lookup
call with an indirect one via the ipv6 stub, which is properly
initialized according to the ipv6 status (e.g. if ipv6 is
disabled, the routing lookup fails gracefully)

Many PCI host controller drivers aren't prepared to have their devices
unbound from them forcefully (e.g., through /sys/.../<driver>/unbind), as
they don't provide any driver .remove callback, where they'd detach the
root bus, release resources, etc. Keeping the driver built in (i.e., not a
loadable module) is not enough; and providing no .remove callback just
means we don't do any teardown.
To rule out the possibility of unbinding a device via sysfs, we need to set
the ".suppress_bind_attrs" field.
I found the suspect drivers via the following search:
git grep -l platform_driver $(git grep -L -e '\.remove' -e suppress_bind_attrs drivers/pci/)
Then I inspected them to ensure that
(a) they set up a PCI bus in their probe() and
(b) they don't have a remove() callback for undoing the setup

According to errata i870, access to the PCIe slave port that are not 32-bit
aligned will result in incorrect mapping to TLP Address and Byte enable
fields.
Accessing non 32-bit aligned data causes incorrect data in the target

The runtime power management functions are called from the reset handler even
if CONFIG_PM is disabled, leading to a link error:
drivers/staging/built-in.o: In function `atomisp_reset':
(.text+0x4cd1c): undefined reference to `atomisp_runtime_suspend'
drivers/staging/built-in.o: In function `atomisp_reset':

drivers/staging/built-in.o: In function `atomisp_reset':
(.text+0x4cd77): undefined reference to `atomisp_runtime_resume'
Removing the #ifdef around the PM functions avoids the problem, and
lets us simplify it further. The __maybe_unused annotation is needed
to ensure the compiler can silently drop the unused callbacks.
