We don't set the type (I/O, memory, etc.) of resources added by
__request_region(), which leads to confusing messages like this:
address space collision: [io 0x1000-0x107f] conflicts with ACPI CPU throttle [??? 0x00001010-0x00001015 flags 0x80000000]
Set the type of a new resource added by __request_region() (used by
request_region() and request_mem_region()) to the type of its parent. This
makes the resource tree internally consistent and fixes messages like the
above, where the ACPI CPU throttle resource really is an I/O port region,
but request_region() didn't fill in the type, so %pR didn't know how to
print it.
Sample dmesg showing the issue at the link below.

Paul reported that after f75b99d5a77d ("PCI: Enforce bus address limits in
resource allocation") on a 32-bit kernel (CONFIG_PHYS_ADDR_T_64BIT not
set), intel-gtt complained "can't ioremap flush page - no chipset
flushing". In addition, other PCI resource allocations, e.g., for bridge
windows, failed.
This happens because we incorrectly skip bus resources of
[mem 0x00000000-0xffffffff] because we think they are of size zero.
When resource_size_t is 32 bits wide, resource_size() on
[mem 0x00000000-0xffffffff] returns 0 because (r->end - r->start + 1)
overflows.
Therefore, we can't use "resource_size() == 0" to decide that allocation
from this resource will fail. allocate_resource() should fail anyway if it
can't satisfy the address constraints, so we should just depend on that.
A [mem 0x00000000-0xffffffff] bus resource is obviously not really valid,
but we do fall back to it as a default when we don't have information about
host bridge apertures.

The generic pci_enable_resources() does essentially the same thing as the
code in the s390 version of pcibios_enable_device().
There are differences, but I don't think any of them are a problem. The
generic code:
- Checks everything up to PCI_NUM_RESOURCES, not PCI_BAR_COUNT (6), so
we'll now check the ROM resource, IOV resources, and bridge windows.
- Checks for res->flags & IORESOURCE_UNSET. The s390 code never sets
IORESOURCE_UNSET, so this isn't a problem.
- Checks res->parent. The s390 pcibios_add_device() calls
pci_claim_resource() on all BARs (except ROM, IOV, and bridge windows)
so this isn't a problem either.

We don't need anything arch-specific in pcibios_enable_device(), so drop
the arch implementation and use the default generic one.
Note: pci_enable_resources() checks that r->parent is non-NULL, which
basically checks that pci_claim_resource() or request_resource() has been
called for each BAR. I don't see where that happens for tile, but this
patch doesn't change that behavior, so if it worked before, it should still
work.

Don't enable memory or I/O decoding if we haven't assigned or claimed the
BAR's resource.
If we enable decoding for a BAR that hasn't been assigned an address, we'll
likely cause bus conflicts. This declines to enable decoding for resources
with IORESOURCE_UNSET.
Note that drivers can use pci_enable_device_io() or pci_enable_device_mem()
if they only care about specific types of BARs. In that case, we don't
bother checking whether the corresponding resources are assigned or
claimed.

It is possible that pairing fails after we've already received remote
identity information. One example of such a situation is when
re-encryption using the LTK fails. In this case the hci_conn object has
already been updated with the identity address but user space does not
yet know about it (since we didn't notify it of the new IRK yet).
To ensure user space doesn't get a Pair Device command response with an
unknown address always use the same address in the response as was used
for the original command.

When performing SMP pairing with MITM protection one side needs to
enter the passkey while the other side displays to the user what needs
to be entered. Nowhere in the SMP specification does it say that the
displaying side needs to any kind of confirmation of the passkey, even
though a code comment in smp.c implies this.
This patch removes the misleading comment and converts the code to use
the passkey notification mgmt event instead of the passkey confirmation
mgmt event.

This netdev op allows the PF driver to control the virtual link state of
the VF devices. This can be used to deny naughty VF drivers access to
the wire, or to allow VFs (regardless of temperament) to communicate
with each other over the device's internal switch even though external
link is down.
Add the actual ndo function, and modify vc_notify_link_state to check
the link status of each VF before sending a message in the case when
physical link changes state.

On 2.4Ghz band, the channels overlap since the delta
between different channels is 5Mhz while the width of the
receiver is 20Mhz (at least).
This means that we can hear beacons or probe responses from
adjacent channels. These frames will have a significant
lower RSSI which will feed all kinds of logic with inaccurate
data. An obvious example is the roaming algorithm that will
think our AP is getting weak and will try to move to another
AP.
In order to avoid this, update the signal only if the frame
has been heard on the same channel as the one advertised by
the AP in its DS / HT IEs.
We refrain from updating the values only if the AP is
already in the BSS list so that we will still have a valid
(but inaccurate) value if the AP was heard on an adjacent
channel only.
To achieve this, stop taking the channel from DS / HT IEs
in mac80211. The DS / HT IEs is taken into account to
discard the frame if it was received on a disabled channel.
This can happen due to the same phenomenon: the frame is
sent on channel 12, but heard on channel 11 while channel
12 can be disabled on certain devices. Since this check
is done in cfg80211, stop even checking this in mac80211.
