This reverts commit 983e6b2636f0099dbac1874c9e885bbe1cf2df05 which is
commit 8a2f11878771da65b8ac135c73b47dae13afbd62 upstream.

It wasn't needed and caused a build break on s390, so just revert it
entirely.

[ Upstream commit 8a2f11878771da65b8ac135c73b47dae13afbd62 ]

After redefining alloc_pages, all uses of that name are being replaced.
Change the conflicting names to prevent preprocessor from replacing them
when it's not intended.

commit 6472036581f947109b20664121db1d143e916f0b upstream.

Make sure to start the kthread to check the power button on qemu as
well if the power button address was provided.
This fixes the qemu built-in system_powerdown runtime command.

commit 6ad6e15a9c46b8f0932cd99724f26f3db4db1cdf upstream.

Firmware returns the physical address of the power switch,
so need to use gsc_writel() instead of direct memory access.

Clean up the code, e.g. make proc_mckinley_root static, drop the now
empty mckinley header file and remove some unneeded ifdefs around procfs

Fixes: 77e0ddf097d6 ("parisc: ccio-dma: Create private runway procfs root entry")

Create an own procfs "runway" root entry for the CCIO driver.
No need to share it with the sba_iommu driver, as only one
of those busses can be active in one machine anyway.
