[PATCH v2 0/3] Fix pci_iounmap() on !CONFIG_GENERIC_IOMAP

[Lorenzo Pieralisi]

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.
