This patch fixes SDHCI CRC errors during of RX throughput testing on
BCM4329 chip if SDIO BUS is clocked above 25MHz. In particular the
checksum problem is observed on NVIDIA Tegra20 SoCs. The good watermark
value is borrowed from downstream BCMDHD driver and it's matching to the
value that is already used for the BCM4339 chip, hence let's re-use it
for BCM4329.

A new warning in clang points out when macro expansion might result in a
GNU C statement expression. There is an instance of this in the mwifiex
driver:
drivers/net/wireless/marvell/mwifiex/cmdevt.c:217:34: warning: '}' and
')' tokens terminating statement expression appear in different macro
expansion contexts [-Wcompound-token-split-by-macro]

macro 'HostCmd_SET_SEQ_NO_BSS_INFO'
(((type) & 0x000f) << 12); }
^
This does not appear to be a real issue. Removing the braces and
replacing them with parentheses will fix the warning and not change the
meaning of the code.

SDHCI changed from using a tasklet to finish requests, to using an IRQ
thread i.e. commit c07a48c2651965 ("mmc: sdhci: Remove finish_tasklet").
Because this increased the latency to complete requests, a preparatory
change was made to complete the request from the IRQ handler if
possible i.e. commit 19d2f695f4e827 ("mmc: sdhci: Call mmc_request_done()
from IRQ handler if possible"). That alleviated the situation for MMC
block devices because the MMC block driver makes use of mmc_pre_req()
and mmc_post_req() so that successful requests are completed in the IRQ
handler and any DMA unmapping is handled separately in mmc_post_req().
However SDIO was still affected, and an example has been reported with
up to 20% degradation in performance.
Looking at SDIO I/O helper functions, sdio_io_rw_ext_helper() appeared
to be a possible candidate for making use of asynchronous requests
within its I/O loops, but analysis revealed that these loops almost
never iterate more than once, so the complexity of the change would not
be warrented.
Instead, mmc_pre_req() and mmc_post_req() are added before and after I/O
submission (mmc_wait_for_req) in mmc_io_rw_extended(). This still has
the potential benefit of reducing the duration of interrupt handlers, as
well as addressing the latency issue for SDHCI. It also seems a more
reasonable solution than forcing drivers to do everything in the IRQ
handler.

The commit cd57d07b1e4e ("sh: don't allow non-coherent DMA for NOMMU") made
CONFIG_NO_DMA to be set for some platforms, for good reasons.
Consequentially, CONFIG_HAS_DMA doesn't get set, which makes the DMA
mapping interface to be built as stub functions, but also prevent the
mmc_spi driver from being built as it depends on CONFIG_HAS_DMA.
It turns out that for some odd cases, the driver still relied on the DMA
mapping interface, even if the DMA was not actively being used.
To fixup the behaviour, let's drop the build dependency for CONFIG_HAS_DMA.
Moreover, as to allow the driver to succeed probing, let's move the DMA
initializations behind "#ifdef CONFIG_HAS_DMA".

As the comments in this patch say, if we tune and find all phases are
valid it's _almost_ as bad as no phases being found valid. Probably
all phases are not really reliable but we didn't detect where the
unreliable place is. That means we'll essentially be guessing and
hoping we get a good phase.
This is not just a problem in theory. It was causing real problems on
a real board. On that board, most often phase 10 is found as the only
invalid phase, though sometimes 10 and 11 are invalid and sometimes
just 11. Some percentage of the time, however, all phases are found
to be valid. When this happens, the current logic will decide to use
phase 11. Since phase 11 is sometimes found to be invalid, this is a
bad choice. Sure enough, when phase 11 is picked we often get mmc
errors later in boot.
I have seen cases where all phases were found to be valid 3 times in a
row, so increase the retry count to 10 just to be extra sure.

The commit 61d7437ed1390 ("mmc: sdhci-acpi: Fix HS400 tuning for AMDI0040")
broke resume for eMMC HS400. When the system suspends the eMMC controller
is powered down. So, on resume we need to reinitialize the controller.
Although, amd_sdhci_host was not getting cleared, so the DLL was never
re-enabled on resume. This results in HS400 being non-functional.
To fix the problem, this change clears the tuned_clock flag, clears the
dll_enabled flag and disables the DLL on reset.

RHBZ: 1871246
If during cifs_lookup()/get_inode_info() we encounter a DFS link
and we use the cifsacl or modefromsid mount options we must suppress
any -EREMOTE errors that triggers or else we will not be able to follow
the DFS link and automount the target.
This fixes an issue with modefromsid/cifsacl where these mountoptions
would break DFS and we would no longer be able to access the share.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'vnic_dev_classifier()', 'vnic_dev_fw_info()',
'vnic_dev_notify_set()' and 'vnic_dev_stats_dump()' (vnic_dev.c) GFP_ATOMIC
must be used because its callers take a spinlock before calling these
functions.
When memory is allocated in '__enic_set_rsskey()' and 'enic_set_rsscpu()'
GFP_ATOMIC must be used because they can be called with a spinlock.
The call chain is:
enic_reset <-- takes 'enic->enic_api_lock'
--> enic_set_rss_nic_cfg
--> enic_set_rsskey
--> __enic_set_rsskey <-- uses dma_alloc_coherent
--> enic_set_rsscpu <-- uses dma_alloc_coherent
When memory is allocated in 'vnic_dev_init_prov2()' GFP_ATOMIC must be used
because a spinlock is hidden in the ENIC_DEVCMD_PROXY_BY_INDEX macro, when
this function is called in 'enic_set_port_profile()'.
When memory is allocated in 'vnic_dev_alloc_desc_ring()' GFP_KERNEL can be
used because it is only called from 5 functions ('vnic_dev_init_devcmd2()',
'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()' and
'enic_wq_devcmd2_alloc()'.
'vnic_dev_init_devcmd2()': already uses GFP_KERNEL and no lock is taken
in the between.
'enic_wq_devcmd2_alloc()': is called from ' vnic_dev_init_devcmd2()'
which already uses GFP_KERNEL and no lock is taken in the between.
'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()': are called
from 'enic_alloc_vnic_resources()'
'enic_alloc_vnic_resources()' has only 2 call chains:
1) enic_probe
--> enic_dev_init
--> enic_alloc_vnic_resources
'enic_probe()' is a probe function and no lock is taken in the between
2) enic_set_ringparam
--> enic_alloc_vnic_resources
'enic_set_ringparam()' is a .set_ringparam function (see struct
ethtool_ops). It seems to only take a mutex and no spinlock.
So all paths are safe to use GFP_KERNEL.

When removing a port from a VLAN we are just erasing the
member config for the VLAN, which is wrong: other ports
can be using it.
Just mask off the port and only zero out the rest of the
member config once ports using of the VLAN are removed
from it.

Registering our slave MDIO bus outside of the OF infrastructure is
necessary in order to avoid creating double references of the same
Device Tree nodes, however it is not sufficient to guarantee that the
MDIO bus diversion is used because of_phy_connect() will still resolve
to a valid PHY phandle and it will connect to the PHY using its parent
MDIO bus which is still the SF2 master MDIO bus. The reason for that is
because BCM7445 systems were already shipped with a Device Tree blob
looking like this (irrelevant parts omitted for simplicity):
ports {
#address-cells = <1>;
#size-cells = <0>;
port@1 {
phy-mode = "rgmii-txid";
phy-handle = <&phy0>;
reg = <1>;
label = "rgmii_1";
};
...
mdio@403c0 {
...
phy0: ethernet-phy@0 {
broken-turn-around;
device_type = "ethernet-phy";
max-speed = <0x3e8>;
reg = <0>;
compatible = "brcm,bcm53125", "ethernet-phy-ieee802.3-c22";
};
};
There is a hardware issue with chip revisions (Dx) that lead to the
development of the following commits:
461cd1b03e32 ("net: dsa: bcm_sf2: Register our slave MDIO bus")
536fab5bf582 ("net: dsa: bcm_sf2: Do not register slave MDIO bus with OF")
b8c6cd1d316f ("net: dsa: bcm_sf2: do not use indirect reads and writes for 7445E0")
There should have been an internal MDIO bus node created for the chip
revision (Dx) that suffers from this problem, but it did not happen back
then.
Had that happen, that we should have correctly parented phy@0 (bcm53125
below) as child node of the internal MDIO bus, but the production Device
Tree blob that was shipped with the firmware targeted the fixed version
of the chip, despite both the affected and corrected chips being shipped
into production.
The problem is that of_phy_connect() for port@1 will happily resolve the
'phy-handle' from the mdio@403c0 node, which bypasses the diversion
completely. This results in this double programming that the diversion
refers to and aims to avoid. In order to force of_phy_connect() to fail,
and have DSA call to dsa_slave_phy_connect(), we must deactivate
ethernet-phy@0 from mdio@403c0, and the best way to do that is by
removing the phandle property completely.

====================
sfc: TXQ refactor
Refactor and unify partner-TXQ handling in the EF100 and legacy drivers.
The main thrust of this series is to remove from the legacy (Siena/EF10)
driver the assumption that a netdev TX queue has precisely two hardware
TXQs (checksummed and unchecksummed) associated with it, so that in
future we can have more (e.g. for handling inner-header checksums) or
fewer (e.g. to free up hardware queues for XDP usage).
Changes from v1:
* better explain patch #1 in the commit message, and rename
xmit_more_available to xmit_pending
* add new patch #2 applying the same approach to ef100, for consistency

This should cause no functional change; merely make there only be one
design of xmit_more handling to understand. As with the EF10/Siena
version, we set tx_queue->xmit_pending when we queue up a TX, and
clear it when we ring the doorbell (in ef100_notify_tx_desc).
While we're at it, make ef100_notify_tx_desc static since nothing
outside of ef100_tx.c uses it.

Instead of using efx_tx_queue_partner(), which relies on the assumption
that tx_queues_per_channel is 2, efx_tx_send_pending() iterates over
txqs with efx_for_each_channel_tx_queue().
We unconditionally set tx_queue->xmit_pending (renamed from
xmit_more_available), then condition on xmit_more for the call to
efx_tx_send_pending(), which will clear xmit_pending. Thus, after an
xmit_more TX, the doorbell is un-rung and xmit_pending is true.
