It turned out that pci_remap_iospace() wasn't undone when the driver's
probe failed, and since devm_phy_optional_get() returned -EPROBE_DEFER,
the probe was retried, finally causing the BUG due to trying to remap
already remapped pages.
The V3 Semiconductor PCI driver has the same issue.
Replace devm_pci_remap_iospace() with its devm_ managed version to fix
the bug.

driver was left disabled, the kernel crashed with this BUG:

Code: f9004ba2 54000080 aa0003fb 17ffff48 (d4210000)
It turned out that pci_remap_iospace() wasn't undone when the driver's
probe failed, and since devm_phy_optional_get() returned -EPROBE_DEFER,
the probe was retried, finally causing the BUG due to trying to remap
already remapped pages.
The X-Gene PCI controller driver has the same issue.
Replace pci_remap_iospace() with the devm_ managed version so that the
pages get unmapped automagically on any probe failure.

PCI: rcar: Clean up PHY init on failure
If the Gen3 PHY fails to power up, the code does not undo the
initialization caused by phy_init(). Add the missing failure

PCI: rcar: Shut the PHY down in failpath
If anything fails past phy_init_fn() and the system is a Gen3 with
a PHY, the PHY will be left on and inited. This is caused by the
phy_init_fn, which is in fact a pointer to rcar_pcie_phy_init_gen3()
function, which starts the PHY, yet has no counterpart in the failpath.
Add that counterpart.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull more overflow updates from Kees Cook:
"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of
manual whitespace updates in the patches as well.
Summary:
- Error path bug fix for overflow tests (Dan)
- Additional struct_size() conversions (Matthew, Kees)
- Explicitly reported overflow fixes (Silvio, Kees)
- Add missing kvcalloc() function (Kees)
- Treewide conversions of allocators to use either 2-factor argument
variant when available, or array_size() and array3_size() as needed

PCI: Collect all native drivers under drivers/pci/controller/
Native PCI drivers for root complex devices were originally all in drivers/pci/host/. Some of these devices can also be operated in endpoint mode. Drivers for endpoint mode didn't seem to fit in the "host" directory, so we put both the root complex and endpoint drivers in per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc. These per-device directories contain trivial Kconfig and Makefiles and clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and collect all the device-specific drivers there. No functional change intended.
