This MIC virtual bus driver takes the responsibility of creating all
the virtual devices connected to the PCIe device on the host and the
platform device on the card. The MIC bus hardware operations provide
a way to abstract certain hardware details from the base physical devices.
Examples of devices added on the MIC virtual bus include host DMA and card DMA.
This abstraction enables using a common DMA driver on host and card.

On some systems, hot-plug tests could hang forever waiting for cpu and
memory to be ready to be offlined. A special hot-plug target is created
to run full range of hot-plug tests. In default mode, hot-plug tests run
in safe mode with a limited scope. In limited mode, cpu-hotplug test is
run on a single cpu as opposed to all hotplug capable cpus, and memory
hotplug test is run on 2% of hotplug capable memory instead of 10%. In
addition to the above change, cpu-hotplug is chnged to change processor
affinity to cpu 0 so it doesn't impact itself while the test runs.

The request for an IRQ handler must be done after whole configuration. This
was not the case for this driver which request the IRQ in the middle of
the configuration. Sometimes, it happens that something is not completely
configured, we recieve an interrupt thus we stumble into troubles in the
IRQ handler.

In some conditions (echo or particular sequence of special
characters), on buffer push, the tty layer calls the write operation
while we are holding the spinlock. This means deadlock within the same
process on kernels version < 3.12. It seems not a problem on recent
kernel, but the patch still valid as locking optimization.
The protected variables by the spinlock are: xmit_buf, nb_bytes,
pointer_read and pointer_write. So, this patch reduces the locked area
in the IRQ handler only to these variables. Most of the code inside the
locked area in the IRQ handler is not protected elsewhere; it means
that it is not protected at all.

commit dabd14684bc2 "PCMCIA: sa1111: remove duplicated initializers"
incorrectly moved some code into the pcmcia_jornada720_init, causing
a few build errors, and for unknown reasons, the driver lacks
an inclusion of <linux/io.h>, so we get the build errors, and more:
sa1111_jornada720.c: In function 'pcmcia_jornada720_init':

The lubbock platform uses the sa1111 companion chip with a pxa250
CPU, which means it requires both the PCMCIA_SA1111 and the
PCMCIA_PXA2XX code to be built into the kernel. Unfortunately,
the Makefile and Kconfig don't agree on how this is accomplished,
leading to a situation where you get this link error when building
a lubbock kernel with PCMCIA_SA1111 enabled but PCMCIA_PXA2XX
disabled:
ERROR: "pxa2xx_configure_sockets" [drivers/pcmcia/sa1111_cs.ko] undefined!
ERROR: "pxa2xx_drv_pcmcia_ops" [drivers/pcmcia/sa1111_cs.ko] undefined!

When building a iPAQ H3100-only kernel with PCMCIA enabled,
we get this build error:
ERROR: "pcmcia_h3600_init" [drivers/pcmcia/sa1100_cs.ko] undefined!

and H3600 support. This patch fixes the Makefile to build the
driver if at least one of the two machines are selected.

All its callers depends on the return value of -ENOBUFS to reallocate a
bigger buffer and retry the receiving. So there's no need to call
pr_err() here since it was not a real issue, otherwise syslog will be

GenWQE used to call pci_enable_msi_block to allocate a desired number
of MSI's. If that was not possible pci_enable_msi_block returned with a
smaller number which might be possible to allocate. GenWQE then called
pci_enable_msi_block with that number.
Since commit a30d0108b
"GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()"
pci_enable_msi_exact is used which fails if the desired number of MSI's
was not possible to allocate. Change GenWQE to use pci_enable_msi_range
to restore the old behavior.

Currently, in the event of a fatal hardware error, the driver tries a
recovery procedure that calls pci_reset_function() to reset the card.
This is not sufficient in some cases, needing a fundamental reset to
bring the card back.
This patch implements a call to the platform fundamental reset procedure
on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled.
This is implemented by default only on PPC64, since this can cause
problems on other archs, e.g. zSeries, where the platform has its own
recovery procedures, leading to a potencial race conditition. For these
cases, the recovery is kept as it was before.

This patch implements the callbacks and functions necessary to have EEH
recovery support.
It adds a config option to enable or disable explicit calls to trigger
platform specific mechanisms on error recovery paths. This option is
enabled by default only on PPC64 systems and can be overritten via
debugfs. If this option is enabled, on the error recovery path the
driver will call pci_channel_offline() to check for error condition and
issue non-raw MMIO reads to trigger early EEH detection in case of
hardware failures. This is necessary since the driver MMIO helper
funtions use raw accessors.
