For the iwlwifi one, Emmanuel says:

"Not all the firmware know how to handle the HOT_SPOT_CMD.
Make sure that the firmware will know this command before

"These two patches are needed to fix a regression introduced when
driver rtl8821ae was moved from staging to the regular wireless tree."

TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets.
If the socket is of family AF_INET6, call ipv6_recv_error instead
of ip_recv_error.

This change is more complex than a single branch due to the loadable
ipv6 module. It reuses a pre-existing indirect function call from
ping. The ping code is safe to call, because it is part of the core
ipv6 module and always present when AF_INET6 sockets are active.

Some VF drivers use the upper byte of "param1" (the qp count field)
in mlx4_qp_reserve_range() to pass flags which are used to optimize
the range allocation.

Under the current code, if any of these flags are set, the 32-bit
count field yields a count greater than 2^24, which is out of range,
and this VF fails.

As these flags represent a "best-effort" allocation hint anyway, they may
safely be ignored. Therefore, the PF driver may simply mask out the bits.

This reverts commit 85c8555f ("KVM: check for !is_zero_pfn() in
kvm_is_mmio_pfn()") and renames the function to kvm_is_reserved_pfn.

The problem being addressed by the patch above was that some ARM code
based the memory mapping attributes of a pfn on the return value of
kvm_is_mmio_pfn(), whose name indeed suggests that such pfns should
be mapped as device memory.

However, kvm_is_mmio_pfn() doesn't do quite what it says on the tin,
and the existing non-ARM users were already using it in a way which
suggests that its name should probably have been 'kvm_is_reserved_pfn'
from the beginning, e.g., whether or not to call get_page/put_page on
it etc. This means that returning false for the zero page is a mistake
and the patch above should be reverted.

Instead of using kvm_is_mmio_pfn() to decide whether a host region

function kvm_is_device_pfn() that disregards RAM pages with the

memory.

If we detect another vCPU is running we just exit and return 0 as if we
succesfully created the VGIC, but the VGIC wouldn't actual be created.

This shouldn't break in-kernel behavior because the kernel will not
observe the failed the attempt to create the VGIC, but userspace could
be rightfully confused.

When running on a system with a GICv3, we currenly don't allow the guest
to access the system register interface of the GICv3.  We do this by
clearing the ICC_SRE_EL2.Enable, which causes all guest accesses to
ICC_SRE_EL1 to trap to EL2 and causes all guest accesses to other ICC_
registers to cause an undefined exception in the guest.

However, we currently don't handle the trap of guest accesses to
ICC_SRE_EL1 and will spill out a warning.  The trap just needs to handle
the access as RAZ/WI, and a guest that tries to prod this register and
set ICC_SRE_EL1.SRE=1, must read back the value (which Linux already
does) to see if it succeeded, and will thus observe that ICC_SRE_EL1.SRE
was not set.

Add the simple trap handler in the sorted table of the system registers.

Currently if using a 48-bit VA, tearing down the hyp page tables (which
can happen in the absence of a GICH or GICV resource) results in the
rather nasty splat below, evidently becasue we access a table that
doesn't actually exist.

Commit 38f791a4 (arm64: KVM: Implement 48 VA support for KVM EL2
and Stage-2) added a pgd_none check to __create_hyp_mappings to account
for the additional level of tables, but didn't add a corresponding check
to unmap_range, and this seems to be the source of the problem.

This patch adds the missing pgd_none check, ensuring we don't try to
access tables that don't exist.

 "This series fix a nasty issue with radeon adapters on powerpc servers,
  it's all CC'ed stable and has the relevant maintainers ack's/reviews.

  Basically, some (radeon) adapters have issues with MSI addresses above
  1T (only support 40-bits).  We had powerpc specific quirk but it only
  listed a specific revision of an adapter that we shipped with our
  machines and didn't properly handle the audio function which some
  distros enable nowadays.

  So we made the quirk generic and fixed both the graphic and audio
  drivers properly to use it.

  Without that, ppc64 server machines will crash at boot with a radeon
  adapter.

  Note: This has been brewing for a while, it just needed a last respin
  which got delayed due to us moving ozlabs to a new location in town
  and other such things taking priority"

If TX channels are set to 4 and RX channels are set to less than 4,
using ethtool -L, the driver will try to initialize more RX channels
than it has allocated, causing an oops.

This fix only initializes the RX ring if it has been allocated.

After commit ca777eff ("tcp: remove dst refcount false sharing for
prequeue mode") we have to relax check against skb dst in
tcp_v[46]_send_reset() if prequeue dropped the dst.

If a socket is provided, a full lookup was done to find this socket,
so the dst test can be skipped.

This reverts commit 5195c14c.

If the conntrack clashes with an existing one, it is left out of
the unconfirmed list, thus, crashing when dropping the packet and
releasing the conntrack since golden rule is that conntracks are
always placed in any of the existing lists for traceability reasons.

====================
Fix outer UDP checksums for IPv6 VXLAN tunnels

In testing against an older kernel I found a couple issues in the IPv6
VXLAN tunnel checksum logic for the outer UDP checksum.

First the default transitioned from using an outer checksum to not using
one.  Second, sometime after that the checksum inputs were changed
resulting the checksum not being correct if it were computed.

These two issues prevented a ping from the newer kernel to the older one.
With these two changes applied I verified I was able to send traffic over
the VXLAN tunnel to a link partner on an older kernel.

The boolean flip fix can be submitted for 3.17 stable as well since the
patch that introduced the issue was included in that kernel.

In "vxlan: Call udp_sock_create" there was a logic error that resulted in
the default for IPv6 VXLAN tunnels going from using checksums to not using
checksums.  Since there is currently no support in iproute2 for setting
these values it means that a kernel after the change cannot talk over a IPv6
VXLAN tunnel to a kernel prior the change.

The UDP checksum calculation for VXLAN tunnels is currently using the
socket addresses instead of the actual packet source and destination
addresses.  As a result the checksum calculated is incorrect in some
cases.

Also uh->check was being set twice, first it was set to 0, and then it is
set again in udp6_set_csum.  This change removes the redundant assignment
to 0.

The xpad wireless endpoint is not a bulk endpoint on my devices, but
rather an interrupt one, so the USB core complains when it is submitted.
I'm guessing that the author really did mean that this should be an
interrupt urb, but as there are a zillion different xpad devices out
there, let's cover out bases and handle both bulk and interrupt
endpoints just as easily.
