qc->n_iter was used for libata's own sg walking before sg chaining
replaced it. During conversion, the field and its usage in sata_fsl
were left behind. Kill the filed and update sata_fsl.
tj: This was part of James's libata-use-block-layer-padding patch.
Separated out by me.

AHCI uses CAP.NP to indicate the number of ports and PI to tell which
ports are enabled. The only requirement is that the number of ports
indicated by CAP.NP should equal or be higher than the number of
enabled ports in PI.
CAP.NP and PI carry duplicate information and there have been some
interesting cases. Some early AHCI controllers didn't set PI at all
and just implement from port 0 to CAP.NP. An ICH8 board which wired
four out of six available ports had 3 (4 ports) for CAP.NP and 0x33
for PI. While ESB2 has less bits set in PI than the value in CAP.NP.
Till now, ahci driver assumed that PI is invalid if it doesn't match
CAP.NP exactly. This violates AHCI standard and the driver ends up
accessing unmimplemented ports on ESB2.
This patch updates CAP.NP and PI handling such that PI can have less
number of bits set than indicated in CAP.NP and the highest port is
determined as the maximum port of what CAP.NP and PI indicate.

<4> <0>Kernel panic - not syncing: Fatal exception in interrupt
<4>
After looking at the code and the dump I think the following scenario
happened: Ifup was running on cpu2 and the interrupt arrived on cpu0.
Now virtnet_open on cpu 2 managed to execute napi_enable and disable_cb
but did not execute rx_schedule. Meanwhile on cpu 0 skb_recv_done was
called by vring_interrupt, executed netif_rx_schedule_prep, which
succeeded and therefore called disable_cb. This triggered the BUG_ON,
as interrupts were already disabled by cpu 2.
I think the proper solution is to make the call to disable_cb depend on
the atomic update of NAPI_STATE_SCHED by using netif_rx_schedule_prep
in the same way as skb_recv_done.

The PHY Lib now uses mutexes instead of spin_locks. ucc_geth
and gianfar both grab the locks in their mdio_reset functions,
so they need to use mutex_(un)lock instead. This was not caught

The driver needs to ack only the phy status bits that it is currently
handling and preserve the other bits for the other handlers. For
example, when reading/writing from the phy, it should not clear the link
change interrupt bit. This will cause a missing link change interrupt.

Iterating through a device node's parents is simple enough, but dealing
with the refcounts properly is a little ugly, and replicating that logic
is asking for someone to get it wrong or forget it all together, eg:
while (dn != NULL) {
/* loop body */
tmp = of_get_parent(dn);
of_node_put(dn);
dn = tmp;
}
So add of_get_next_parent(), inspired by of_get_next_child(). The
contract is that it returns the parent and drops the reference on the
current node, this makes the loop look like:
while (dn != NULL) {
/* loop body */
dn = of_get_next_parent(dn);
}

This patch converts cpmac to the new Fixed PHY infrastructure, though it
doesn't fix all the problems with that driver. I didn't even bother to
test this patch to compile, because cpmac driver is broken in several ways:
1. This driver won't compile by itself because lack of its header describing
platform data;
2. It assumes that fixed PHYs should be created by the ethernet driver.
It is wrong assumption: fixed PHYs creation is platform code authority,
driver must blindly accept bus_id and phy_id platform data variables
instead.
Also, it seem that that driver doesn't have actual in-tree users, so
nothing to fix further.
The main purpose of that patch is to get rid of the following Kconfig
warning:
scripts/kconfig/conf -s arch/powerpc/Kconfig
drivers/net/Kconfig:1713:warning: 'select' used by config symbol
'CPMAC' refers to undefined symbol 'FIXED_MII_100_FDX'

Teach the debug logging macro to differentiate between log levels based on the
type of debug level enabled specifically instead of a threshold-based one.
Thus, convert tape->debug_level to a bitmask that is written to over /proc.
Also,
- cleanup and simplify the debug macro thus removing a lot of code lines,
- get rid of unused debug levels,
- adjust the loglevel at several places where it was simply missing (e.g.
idetape_chrdev_open())
- move the tape ptr initialization up in idetape_chrdev_open() so that we can
use it in the debug_log macro earlier in the function.
