gpio: move mpc8xxx/512x gpio driver to drivers/gpio
Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
the platforms, because this option is per-platform and not per-driver.

ARM: mach-nuc93x: delete
This architecture received only generic maintenance since December 2009
when it was originally submitted, and no actual additional support since
then. It has no defconfig entry either, meaning that it was never built

when CONFIG_MACH_NUC932EVB is selected which is the only possible config
choice.
This is therefore dead code and should be removed. If someone wants to
revive this code, it could be retrieved from the Git repository, and
ideally be merged in mach-w90x900/ instead.

ARM: mach-ux500: unlock I&D l2x0 caches before init
Apparently U8500 U-Boot versions may leave the l2x0 locked down
before executing the kernel. Make sure we unlock it before we
initialize the l2x0. This fixes a performance problem reported
by Jan Rinze.
The l2x0 core has been modified to unlock the l2x0 by default,
but it will not touch the locking registers if the l2x0 was
already enabled, as on the ux500, so we need this quirk to
make sure it is properly turned off.

[SCSI] ipr: Stop reading adapter dump prematurely
When the ipr driver decides to dump the adapter, it changes the
sdt_state to GET_DUMP, then prepares the adapter so that the dump
can be read. However, if the ipr worker thread wakes up for some
reason before the driver has put the adapter in a state where it
can succesfully dump the adapter, the driver will start dumping
the adapter too early, which can potentially trigger a BUG check
in the pci config blocking API. Fix this by adding a new
sdt_state to differentiate between the ipr driver wanting to dump
the adapter in the near future and wanting to dump the adapter now.

Following reports on the list, it looks like the 3e-9xxx driver will leak dma
mappings every time we get a transient queueing error back from the card.
This is because it maps the sg list in the routine that sends the command, but
doesn't unmap again in the transient failure path (even though the command is
sent back to the block layer). Fix by unmapping before returning the status.

[SCSI] mpt2sas: Added NUNA IO support in driver which uses multi-reply queue support of the HBA
Support added for controllers capable of multi reply queues.
The following are the modifications to the driver to support NUMA.
1) Create the new structure adapter_reply_queue to contain the reply queue
info for every msix vector. This object will contain a
reply_post_host_index, reply_post_free for each instance, msix_index, among
other parameters. We will track all the reply queues on a link list called
ioc->reply_queue_list. Each reply queue is aligned with each IRQ, and is
passed to the interrupt via the bus_id parameter.
(2) The driver will figure out the msix_vector_count from the PCIe MSIX
capabilities register instead of the IOC Facts->MaxMSIxVectors. This is
because the firmware is not filling in this field until the driver has
already registered MSIX support.
(3) If the ioc_facts reports that the controller is MSIX compatible in the
capabilities, then the driver will request for multiple irqs. This count
is calculated based on the minimum between the online cpus available and
the ioc->msix_vector_count. This count is reported to firmware in the
ioc_init request.
(4) New routines were added _base_free_irq and _base_request_irq, so
registering and freeing msix vectors were done thru simple function API.
(5) The new routine _base_assign_reply_queues was added to align the msix
indexes across cpus. This will initialize the array called
ioc->cpu_msix_table. This array is looked up on every MPI request so the
MSIxIndex is set appropriately.
(6) A new shost sysfs attribute was added to report the reply_queue_count.
(7) User needs to set the affinity cpu mask, so the interrupts occur on the
same cpu that sent the original request.
