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.

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:

461cd1b0 ("net: dsa: bcm_sf2: Register our slave MDIO bus")
536fab5b ("net: dsa: bcm_sf2: Do not register slave MDIO bus with OF")
b8c6cd1d ("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.

We can sometimes get bogus thermal shutdowns on omap4430 at least with
droid4 running idle with a battery charger connected:

thermal thermal_zone0: critical temperature reached (143 C), shutting down

Dumping out the register values shows we can occasionally get a 0x7f value
that is outside the TRM listed values in the ADC conversion table. And then
we get a normal value when reading again after that. Reading the register
multiple times does not seem help avoiding the bogus values as they stay
until the next sample is ready.

Looking at the TRM chapter "18.4.10.2.3 ADC Codes Versus Temperature", we
should have values from 13 to 107 listed with a total of 95 values. But
looking at the omap4430_adc_to_temp array, the values are off, and the
end values are missing. And it seems that the 4430 ADC table is similar
to omap3630 rather than omap4460.

Let's fix the issue by using values based on the omap3630 table and just
ignoring invalid values. Compared to the 4430 TRM, the omap3630 table has
the missing values added while the TRM table only shows every second
value.

Note that sometimes the ADC register values within the valid table can
also be way off for about 1 out of 10 values. But it seems that those
just show about 25 C too low values rather than too high values. So those
do not cause a bogus thermal shutdown.

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 'epic_init_one()', GFP_KERNEL can be used
because it is a probe function and no lock is acquired.

Fix spacing issues reported for misaligned switch..case and extra new
lines.

Also updated the file header to comply with networking commet style.

Whenever a port gets enabled/disabled, recalcultate the required switch
clock rate to make sure it always gets set to the expected rate
targeting our switch use case. This is only done for the BCM7445 switch
as there is no clocking profile available for BCM7278.

Fetch the corresponding clock resource and enable/disable it during
suspend/resume if and only if we have no ports defined for Wake-on-LAN.

It is necessary to manage the Wake-on-LAN clock to turn on the
appropriate blocks for MPD or CFP-based packet matching to work
otherwise we will not be able to reliably match packets during suspend.

We disable clocks shortly after probing the device to save as much power as
possible in case the interface is never used. When bcm_sysport_open() is
invoked, clocks are enabled, and disabled in bcm_sysport_stop().

A similar scheme is applied to the suspend/resume functions.
