aer_hest_parse() and aer_hest_parse_aff() are almost identical. We use
aer_hest_parse() to check the ACPI_HEST_FIRMWARE_FIRST flag for a specific
device, and we use aer_hest_parse_aff() to check to see if any device sets
the flag.
This drops aer_hest_parse_aff() and enhances aer_hest_parse() so it

aer_set_firmware_first() searches the HEST for an error source descriptor

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").

Make pcie-io-aperture and the IO port MBUS ID in ranges optional. If not
provided the bridge reports to Linux that IO space mapping is not supported
and refuses to configure an IO MBUS window.
This allows both complete disable (do not specify pcie-io-aperture) and
per-port disable (do not specify a IO target ranges entry for the port).
Most PCIe devices these days do not require IO support to function, so
having an option to disable it in the driver is useful.

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

There are no writable bits in the secondary status register, only RO and
RW1C (write-1-to-clear) bits. The driver never sets any of the RW1C bits,
so the status register should always be 0, just remove the set from the
write path.
Someday the RW1C bits should be copied/cleared directly from registers in
the HW.

(Mika Westerberg sees them too in his tests).
Some investigation documented in kernel bug #65281 led me to the
conclusion that the source of the problem is the device_del() in
pci_stop_dev() as it now causes the sysfs directory of the device to be
removed recursively along with all of its subdirectories. That includes
the sysfs directory of the device's subordinate bus (dev->subordinate) and
its "power" group.
Consequently, when pci_remove_bus() is called for dev->subordinate in
pci_remove_bus_device(), it calls device_unregister(&bus->dev), but at this
point the sysfs directory of bus->dev doesn't exist any more and its
"power" group doesn't exist either. Thus, when dpm_sysfs_remove() called
from device_del() tries to remove that group, it triggers the above
warning.
That indicates a logical mistake in the design of
pci_stop_and_remove_bus_device(), which causes bus device objects to be
left behind their parents (bridge device objects) and can be fixed by
moving the device_del() from pci_stop_dev() into pci_destroy_dev(), so
pci_remove_bus() can be called for the device's subordinate bus before the
device itself is unregistered from the hierarchy. Still, the driver, if
any, should be detached from the device in pci_stop_dev(), so use
device_release_driver() directly from there.

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

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"
