* pci/deletion:
PCI: Remove from bus_list and release resources in pci_release_dev()
PCI: Move pci_proc_attach_device() to pci_bus_add_device()

PCI: Move device_del() from pci_stop_dev() to pci_destroy_dev()

Previously we removed the pci_dev from the bus_list and released its
resources in pci_destroy_dev(). But that's too early: it's possible to
call pci_destroy_dev() twice for the same device (e.g., via sysfs), and
that will cause an oops when we try to remove it from bus_list the second
time.
We should remove it from the bus_list only when the last reference to the
pci_dev has been released, i.e., in pci_release_dev().

4f535093cf ("PCI: Put pci_dev in device tree as early as possible")
moved pci_proc_attach_device() from pci_bus_add_device() to
pci_device_add().
This moves it back to pci_bus_add_device(), essentially reverting that
part of 4f535093cf. This makes it symmetric with pci_stop_dev(),
where we call pci_proc_detach_device() and pci_remove_sysfs_dev_files()
and set dev->is_added = 0.

To be consistent with 4bff674990 ("PCI: Move device_del() from
pci_stop_dev() to pci_destroy_dev()", this changes pci_stop_root_bus()
to use device_release_driver() instead of device_del().
This also changes pci_remove_root_bus() to use device_unregister()
instead of put_device() so it corresponds with the device_register()
call in pci_create_root_bus().

aer_set_firmware_first() searches the HEST for an error source descriptor
matching the specified PCI device. It uses the apei_hest_parse() iterator
to call aer_hest_parse() for every descriptor in the HEST.
Previously, aer_hest_parse() incorrectly assumed every descriptor was for a
PCIe error source. This patch adds a check to avoid that error.

pci_setup_bridge_io() accessed PCI_IO_BASE and PCI_IO_LIMIT using dword
(32-bit) reads and writes, which also access the Secondary Status register.
Since the Secondary Status register is in the upper 16 bits of the dword,
and we preserved those upper 16 bits, this had the effect of clearing any
of the write-1-to-clear bits that happened to be set in the Secondary
Status register.
That's not what we want, so use word (16-bit) accesses to update only
PCI_IO_BASE and PCI_IO_LIMIT.

pci_bridge_check_ranges() determines whether the bridge supports an I/O
aperture and a prefetchable memory aperture.
Previously, if the I/O aperture was unsupported, disabled, or configured at
[io 0x0000-0x0fff], we wrote 0xf0 to PCI_IO_BASE and PCI_IO_LIMIT, which,
if the bridge supports it, enables the I/O aperture at [io 0xf000-0xffff].
The enabled aperture may conflict with other devices in the system.
Similarly, we wrote 0xfff0 to PCI_PREF_MEMORY_BASE and
PCI_PREF_MEMORY_LIMIT, which enables the prefetchable memory aperture at
[mem 0xfff00000-0xffffffff], and that may also conflict with other devices.
All we need to know is whether the base and limit registers are writable,
so we can use values that leave the apertures disabled, e.g., PCI_IO_BASE =
0xf0, PCI_IO_LIMIT = 0xe0, PCI_PREF_MEMORY_BASE = 0xfff0,
PCI_PREF_MEMORY_LIMIT = 0xffe0.
Writing non-zero values to both the base and limit registers means we
detect whether either or both are writable, as we did before.

Add a flag to tell the PCI subsystem that kernel is shutting down in
preparation to kexec a kernel. Add code in PCI subsystem to use this flag
to clear Bus Master bit on PCI devices only in case of kexec reboot.
This fixes a power-off problem on Acer Aspire V5-573G and likely other
machines and avoids any other issues caused by clearing Bus Master bit on
PCI devices in normal shutdown path. The problem was introduced by
b566a22c23 ("PCI: disable Bus Master on PCI device shutdown").

The emulated bridge does not support interrupts, so it should return the
value 0 for Interrupt Line and Interrupt Pin. This indicates that
interrupts are not supported.
Since Max_Lat and Min_Gnt are also in the same 32-bit word, we return
0 for them, which means "do not care."
This corrects an error message from the kernel:
pci 0000:00:01.0: of_irq_parse_pci() failed with rc=135
Which is due to the default return of 0xFFFFFFFF indicating that
interrupts are supported.
The error message regression was caused by 16b84e5a50 ("of/irq: Create

(PF driver .probe() method -> pci_enable_sriov() -> add VFs -> VF driver
.probe method).
961da7fb6b22 ("PCI: Avoid unnecessary CPU switch when calling driver

If we are already on a CPU local to the device, call the driver .probe()
method directly without using work_on_cpu().
This is a workaround for a lockdep warning in the following scenario:
pci_call_probe
work_on_cpu(cpu, local_pci_probe, ...)
driver .probe
pci_enable_sriov
...
pci_bus_add_device
...
pci_call_probe
work_on_cpu(cpu, local_pci_probe, ...)
It would be better to fix PCI so we don't call VF driver .probe() methods
from inside a PF driver .probe() method, but that's a bigger project.

Pull DRM fixes from Dave Airlie:
"I was going to leave this until post -rc1 but sysfs fixes broke
hotplug in userspace, so I had to fix it harder, otherwise a set of
pulls from intel, radeon and vmware,
The vmware/ttm changes are bit larger but since its early and they are
unlikely to break anything else I put them in, it lets vmware work
with dri3"

Pull networking fixes from David Miller:
1) Fix memory leaks and other issues in mwifiex driver, from Amitkumar
Karwar.
2) skb_segment() can choke on packets using frag lists, fix from
Herbert Xu with help from Eric Dumazet and others.
3) IPv4 output cached route instantiation properly handles races
involving two threads trying to install the same route, but we
forgot to propagate this logic to input routes as well. Fix from
Alexei Starovoitov.
4) Put protections in place to make sure that recvmsg() paths never
accidently copy uninitialized memory back into userspace and also
make sure that we never try to use more that sockaddr_storage for
building the on-kernel-stack copy of a sockaddr. Fixes from Hannes
Frederic Sowa.
5) R8152 driver transmit flow bug fixes from Hayes Wang.
6) Fix some minor fallouts from genetlink changes, from Johannes Berg
and Michael Opdenacker.

from under us. Fix from Daniel Borkmann.
