Reset methods don't have access to phys link status for slave links
and may incorrectly indicate device presence causing unnecessary probe
failures for unoccupied links. This patch clears device class to NONE
during post-reset processing if phys link is offline.
As on/offlineness semantics is strictly defined and used in multiple
places by the core layer, this won't change behavior for drivers which
don't use slave links.

Slave link action mask is transferred to master link and all the EH
actions are taken by the master link. ata_eh_about_to_do() and
ata_eh_done() are called with ATA_EH_ALL_ACTIONS to clear the slave
link actions during transfer. This always sets ATA_PFLAG_RECOVERED
flag causing spurious "EH complete" messages.
Don't set ATA_PFLAG_RECOVERED for slave link actions.

ATA_EHI_NO_AUTOPSY and ATA_EHI_QUIET are used to control the behavior
of EH. As only the master link is visible outside EH, these flags are
set only for the master link although they should also apply to the
slave link, which causes spurious EH messages during probe and
suspend/resume.
This patch transfers those two flags to slave ehc.i before performing
slave autopsy and reporting.

Since the ehca device driver does not support dynamic memory add and
remove operations, the driver must explicitly reject such requests in
order to prevent unpredictable behaviors related to existing memory
regions that cover all of memory being used by InfiniBand protocols in
the kernel.
The solution (for now at least) is to add a memory notifier to the
ehca device driver and if a request for dynamic memory add or remove
comes in, ehca will always reject it. The user can add or remove
memory by hot-removing the ehca adapter, performing the memory
operation, and then hot-adding the ehca adapter back.

Because ehca adapters can differ in the maximum number of QPs and CQs
we have to save the maximum number of these ressources per adapter and
not globally per ehca driver. This fix introduces 2 new members to the
shca structure to store the maximum value for QPs and CQs per adapter.
The module parameters are now used as initial values for those
variables. If a user selects an invalid number of CQs or QPs we don't
print an error any longer, instead we will inform the user with a
warning and set the values to the respective maximum supported by the
HW.

The Mellanox ConnectX can operate as an InfiniBand adapter, as an
Ethernet NIC, or as a Fibre Channel (FC) HBA. The kernel has a
low-level driver, mlx4_core, which handles multiplexing access to the
device, and there is also already an InfiniBad driver, mlx4_ib.
This patch adds a new driver, mlx4_en, which implements a standard
Ethernet NIC driver.

Multi-protocol adapters support different port types. Each consumer
of mlx4_core queries for supported port types; in particular mlx4_ib
can no longer assume that all physical ports belong to it. Port type
is configured through a sysfs interface. When the type of a port is
changed, all mlx4 interfaces are unregistered, and then registered
again with the new port types.

For ethernet support, we need to reserve QPs for the ethernet and
fibre channel driver. The QPs are reserved at the end of the QP
table. (This way we assure that they are aligned to their size)
We need to consider these reserved ranges in bitmap creation, so we
extend the mlx4 bitmap utility functions to allow reserved ranges at
both the bottom and the top of the range.

This adds basic support for the GPIOs in the twl4030 power management
chip. That includes two open drain LED drivers, and the use of GPIO-0
(and GPIO-1) as MMC/SD card detect switches which can control whether
the VMMC1 (and VMMC2) regulators are active.
This version of the code has a debounce call that will probably be
replaced before long, when a more generic interface exists.

This adds a driver for the RTC inside the TWL4030 multi-function device.
It's a fairly basic RTC, with a wake-capable alarm.
Note that many of the pre-release Overo boards now in circulation can't
effectively use this RTC, because of a wiring error that puts its TWL
chip into "secure" mode. (As in "secure yourself against tampering".)
This isn't an issue on other OMAP3 boards now supported in mainline,
such as Beagle and Labrador.

- Move it into a separate file; clean and streamline it
- Restructure the init code for reuse during secondary dispatch
- Support both levels (primary, secondary) of IRQ dispatch
- Use a workqueue for irq mask/unmask and trigger configuration
Code for two subchips currently share that secondary handler code.
One is the power subchip; its IRQs are now handled by this core,
courtesy of this patch. The other is the GPIO module, which will
be supported through a later patch.
There are also minor changes to the header file, mostly related
to GPIO support; nothing yet in mainline cares about those. A
few references to OMAP-specific symbols are disabled; when they
can all be removed, the TWL4030 support ceases being OMAP-specific.

A common thing in many PCI drivers is to ioremap() an entire bar. This
is a slightly fragile thing right now, needing both an address and a
size, and many driver writers do.. various things there.
This patch introduces an pci_ioremap() function taking just a PCI device
struct and the bar number as arguments, and figures this all out itself,
in one place. In addition, we can add various sanity checks to this
function (the patch already checks to make sure that the bar in question
really is a MEM bar; few to no drivers do that sort of thing).
Hopefully with this type of API we get less chance of mistakes in
drivers with ioremap() operations.
