In rtw_mlme_ext.c, nested #ifdef blocks form the following
structure inside the file:
#ifdef CONFIG_8723AU_AP_MODE (line 1323)
[...]
#ifdef CONFIG_8723AU_AP_MODE (line 1720)
[...]
#endif
(2 more ifdef blocks with CONFIG_8723AU_AP_MODE follow)
[...]
#endif /* CONFIG_8723AU_AP_MODE */ (line 1763)
The inner #ifdefs are unnecessary as they depend on the
same condition as the outer #ifdef and can thus be removed.

git://anongit.freedesktop.org/tegra/linux into drm-next
drm/tegra: Changes for v4.2-rc1
This contains a couple of mostly fixes for issues that have crept up in
recent versions of linux-next. One issue is that DP AUX transactions of
more than 4 bytes will access the wrong FIFO registers and hence become
corrupt. Another fix is required to restore functionality of Tegra20 if
using the GART. The current code expects the IOMMU aperture to be the
complete 4 GiB address space, whereas the GART on Tegra20 only provides
a 128 MiB aperture. One more issue with IOMMU support is that on 64-bit
ARM, swiotlb is the default IOMMU implementation backing the DMA API. A
side-effect of that is that when dma_map_sg() is called to flush caches
(yes, this is a bit of a hack, but ARM does not provide a better API),
swiotlb will immediately run out of memory because its bounce buffer is
too small to make a framebuffer.
Finally I've included a mostly cosmetic fix that stores register values
in u32 rather than unsigned long to avoid sign-extension issues on 64-
bit ARM. This is only a precaution since it hasn't caused any issues
(yet).

The pciehp debug logging is overly verbose and often redundant. Almost all
of the information printed by dbg_ctrl() is also printed by the normal PCI
core enumeration code and by pcie_init().
Remove the redundant debug info.
When claiming a pciehp bridge, we print the slot characteristics, e.g.,
Slot #6 AttnBtn- AttnInd- PwrInd- PwrCtrl- MRL- Interlock- NoCompl+ LLActRep+
Add the Hot-Plug Capable and Hot-Plug Surprise bits to this information,
and print it all in the same order as lspci does.
No functional change except the message text changes.

When a VF issues an LPORT_STATE request to enable a port that is already
enabled, the PF will first disable the VF LPORT. Then it should
re-enable the VF again with the new requested settings. This ensures
that any switch rules are cleared by deleting the LPORT on the switch.
However, the flow is bugged because we actually check if the VF is
enabled at the end, and thus don't re-enable it. Fix the flow so that we
actually clear the enabled flags as part of our removal of the LPORT.

This patch adds the __attribute__((packed)) indicator to some structures
which are overlayed onto a TLV message. These structures must be packed
as small as possible in order to correctly align when copied into the
mailbox buffer. Without doing so, the receiving mailbox code incorrectly
parses the values and we get invalid message responses from the switch
manager software.

During initialization, the VF counts its rings by walking the TQDLOC
registers. This works only if the TQMAP/RQMAP registers are set to map
all of the out-of-bound rings back to the first one. This allows the VF
to cleanly detect when it has run out of queues. Update the PF code so
that it resets the empty TQMAP/RQMAP registers post-VFLR to prevent
innocent VF drivers from triggering malicious driver events.

Currently, we don't notify the switch at all when the PF
administratively sets a new VLAN or MAC address. This causes the old
addresses to remain valid on the switch table. Since the PF is
overriding any configuration done directly by the VF, we choose to
simply re-create the LPORT for the VF. This does mean that all rules for
the VF will be dropped when we set something directly via the PF, but it
prevents some weird issues where the MAC/VLAN table retains some stale
configuration.

This patch cleans up the use of dma_get_required_mask and uses the
simpler dma_set_mask_and_coherent function instead of doing these as
separate steps.
I removed the dma_get_required_mask call because based on some minimal
testing it appears that either (a) we're not doing the right thing with
the call or (b) we don't need it anyways. If the value returned is
<48bits, we'll end up trying with 48 bits anyways. If it's over 48bits,
fm10k can't support that anyways, and we should try 48bits. If 48bits
fails, we'll fallback to 32bits. This cleans up some very funky code.

This prevents a memory leak in fm10k_set_ringparams. The leak occurs
because we go down, change ring parameters, and then come up. However,
fm10k_down on its own is not clearing the Rx rings. Since fm10k_up
assumes the rings are clean we basically drop the buffers and leak a
bunch of memory. Eventually we hit dirty page faults and reboot the
system. This issue does not occur elsewhere because other flows that
involve fm10k_down go through fm10k_close which immediately called
fm10k_free_all_rx_resources which properly cleans the rings.

This patch resolves a bug in the ts_tx_enqueue code responsible for a
NULL pointer dereference and invalid access of the skb list. We
incorrectly freed the actual skb we found instead of our copy. Thus the
skb queue is essentially invalidated. Resolve this by freeing our clone
in the cases where we did not add it to the queue. This also avoids the
skb memory leak caused by failure to free the clone.

skb_complete_tx_timestamp is intended for use by PHY drivers which
implement a different method of returning timestamps. This method is
intended to be used after a PHY driver accepts a cloned packet via its
phy_driver.txtstamp function. It is not correct to use in the standard
ethernet driver such as fm10k. This patch fixes the following possible
kernel panic.

This change fixes an issue with adding an invalid multicast address
using the iproute2 tool (ip maddr add <MADDR> dev <dev>). The iproute2
tool and the kernel do not validate or filter the multicast addresses
when adding them to the multicast list. Thus, when synchronizing this
list with an invalid entry, the action will be aborted with an error
since the fm10k driver currently validates the list. Consequently,
multicast entries beyond the invalid one will not be processed and
communicated with the switch via the mailbox. This change makes it so
that invalid addresses will simply be skipped and allows synchronizing
the full list to proceed.
