1. We don't really need such a big on-stack buffer when sending the
teardown_packet: vmbus_sendpacket() here only uses sizeof(struct
pci_message).
2. In the hot-remove case (PCI_EJECT), after we send PCI_EJECTION_COMPLETE
to the host, the host will send a RESCIND_CHANNEL message to us and the
host won't access the per-channel ringbuffer any longer, so we needn't send
PCI_RESOURCES_RELEASED/PCI_BUS_D0EXIT to the host, and we shouldn't expect
the host's completion message of PCI_BUS_D0EXIT, which will never come.
3. We should send PCI_BUS_D0EXIT after hv_send_resources_released().

During enumeration with multi-function EP devices, access to the
configuration space of a non-existent function results in an unsupported
request being returned as expected. By default the PAXB-based iProc PCIe
controller forwards this as an APB error to the host system and that causes
an exception, which is undesired.
Disable this undesired behaviour and let the kernel PCI stack deal with an
access to the non-existent function, in which case a vendor ID of 0xffff is
returned and handled gracefully.

The iProc PCIe driver is currently using type IPROC_PCIE_PAXB for the
following SoCs: NS, NSP, Cygnus, NS2, and Pegasus. In fact, the BCMA-based
NS uses a legacy PAXB controller that is slightly different from the PAXB
controller used in the rest of SoCs, e.g., some registers are missing and
it does not require software configuration of outbound/inbound address
mapping.
Add a new type, IPROC_PCIE_PAXB_BCMA, to allow us to properly support the
BCMA-based NS along with other iProc-based SoCs going forward.

During initialization, the current iProc PCIe host driver resets PAXC and
the downstream internal endpoint device that PAXC connects to. If the
endpoint device is already loaded with firmware and has started running
from the bootloader stage, this downstream reset causes the endpoint device
to stop working.

As the number of iProc PCIe core registers starts to grow and differ
between different revisions of the iProc PCIe controllers, the
current way of populating each individual unsupported register with
value 'IPROC_PCIE_REG_INVALID' with a table entry has become a bit
messy and is difficult to scale up in the future.
Improve the current driver by populating the invalid entries with code
instead of through individual table entries. This helps to avoid a
significant number of invalid table entries when support for the next
revision of the iProc controller is added.

One some systems, the firmware does not allow certain PCI devices to be put
in deep D-states. This can cause problems for wakeup signalling, if the
device does not support PME# in the deepest allowed suspend state. For
example, Pierre reports that on his system, ACPI does not permit his xHCI
host controller to go into D3 during runtime suspend -- but D3 is the only
state in which the controller can generate PME# signals. As a result, the
controller goes into runtime suspend but never wakes up, so it doesn't work
properly. USB devices plugged into the controller are never detected.
If the device relies on PME# for wakeup signals but is not capable of
generating PME# in the target state, the PCI core should accurately report
that it cannot do wakeup from runtime suspend. This patch modifies the
pci_dev_run_wake() routine to add this check.

pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory. But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst. The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.

This is a variant of pci_alloc_irq_vectors() that allows passing a struct
irq_affinity to provide fine-grained IRQ affinity control.
For now this means being able to exclude vectors at the beginning or end of
the MSI vector space, but it could also be used for any other quirks needed
in the future (e.g. more vectors than CPUs, or excluding CPUs from the
spreading).

If we're using a shadow copy of a PCI device ROM, the shadow copy is in RAM
and the device never sees accesses to it and doesn't respond to it. We
don't have to route the shadow range to the PCI device, and the device
doesn't have to claim the range.
Previously we treated the shadow copy as though it were the ROM BAR, and we
failed to claim it because the region wasn't routed to the device:
pci 0000:01:00.0: Video device with shadowed ROM at [mem 0x000c0000-0x000dffff]
pci_bus 0000:01: Allocating resources
pci 0000:01:00.0: can't claim BAR 6 [mem 0x000c0000-0x000dffff]: no compatible bridge window
The failure path of pcibios_allocate_dev_rom_resource() cleared out the
resource start address, which also caused the following ioremap() warning:
WARNING: CPU: 0 PID: 116 at /build/linux-akdJXO/linux-4.8.0/arch/x86/mm/ioremap.c:121 __ioremap_caller+0x1ec/0x370

Handle an option ROM shadow copy as RAM, without trying to insert it into
the iomem resource tree.
This fixes a regression caused by 0c0e0736acad ("PCI: Set ROM shadow
location in arch code, not in PCI core"), which appeared in v4.6. The
regression causes video device initialization to fail. This was reported
on AMD Turks, but it likely affects others as well.

Commit cc7cc02bada8 ("PCI: Query platform firmware for device power
state") augmented struct pci_platform_pm_ops with a ->get_state hook and
implemented it for acpi_pci_platform_pm, the only pci_platform_pm_ops
existing till v4.7.
However v4.8 introduced another pci_platform_pm_ops for Intel Mobile
Internet Devices with commit 5823d0893ec2 ("x86/platform/intel-mid: Add
Power Management Unit driver"). It is missing the ->get_state hook,
which is fatal since pci_set_platform_pm() enforces its presence. Andy
Shevchenko reports that without the present commit, such a device
"crashes without even a character printed out on serial console and
reboots (since watchdog)".
Retrofit mid_pci_platform_pm with the missing callback to fix the
breakage.

Only interfaces used from outside the driver, e.g., those called by the
DesignWare core, need to accept pointers to the generic struct pcie_port.
Internal interfaces can accept pointers to the device-specific struct,
which makes them more straightforward. No functional change intended.
