v2 of a previous posting.

v1->v2:
	- Added additional patch to remove sparc32 useless __KERNEL__
	  guard

v1: https://lore.kernel.org/lkml/20200915093203.16934-1-lorenzo.pieralisi@arm.com

Original cover letter
---

Fix the empty pci_iounmap() implementation that is causing memory leaks on
!CONFIG_GENERIC_IOMAP configs relying on asm-generic/io.h.

A small tweak is required on sparc32 to pull in some declarations,
hopefully nothing problematic, subject to changes as requested.

Previous tentatives:

Arnd, David, Bjorn,

I have got review/test tags, is it OK if we merge this series please ?

Can we pull it in the PCI tree or you want it to go via a different
route upstream ?

Please let me know.

Thanks,
Lorenzo

Going through the PCI tree sounds good to me, but I can
take it through the asm-generic tree if Bjorn doesn't want to
pick it up there.

Bjorn, can we pull this series into PCI tree please - if that's OK
with you ?

Thanks,
