This patch removes SIOCDEVPRIVATE + 1 ioctl. It currently is just a
stub which does some useless printks and returns. In the original code,
if the user passes priv_cmd.total_len == 0 then it will Oops. Also it
leaks memory every time it's called. In the future, we will implement
this functionality using generic API functions

It is a Bad Idea (TM) to call mtd_device_register() or
mtd_device_parse_register() twice on the same master MTD. Among other
things, it makes partition overrides (e.g., cmdlinepart) much more
difficult.
Since commit 727dc612c4 ("mtd: part: Create the master device node
when partitioned"), we now have a config option that accomplishes the
same purpose as the double-registration done in diskonchip.c -- it
forces the master MTD to *always* be registered, while partitions may
optionally show up in addition. Eventually, we might like to make
CONFIG_MTD_PARTITIONED_MASTER into the default, but this could be
disruptive to user-space expectations of MTD numbering, so we'll take
that slowly.

I noticed heavy spin lock contention at get_active_stripe() with fsmark
multiple thread write workloads.
Here is how this hot contention comes from. We have limited stripes, and
it's a multiple thread write workload. Hence, those stripes will be taken
soon, which puts later processes to sleep for waiting free stripes. When
enough stripes(>= 1/4 total stripes) are released, all process are woken,
trying to get the lock. But there is one only being able to get this lock
for each hash lock, making other processes spinning out there for acquiring
the lock.
Thus, it's effectiveless to wakeup all processes and let them battle for
a lock that permits one to access only each time. Instead, we could make
it be a exclusive wake up: wake up one process only. That avoids the heavy
spin lock contention naturally.
To do the exclusive wake up, we've to split wait_for_stripe into multiple
wait queues, to make it per hash value, just like the hash lock.
Here are some test results I have got with this patch applied(all test run
3 times):

I noticed heavy spin lock contention at get_active_stripe(), introduced
at being wake up stage, where a bunch of processes try to re-hold the
spin lock again.
After giving some thoughts on this issue, I found the lock could be
relieved(and even avoided) if we turn the wait_for_stripe to per
waitqueue for each lock hash and make the wake up exclusive: wake up
one process each time, which avoids the lock contention naturally.
Before go hacking with wait_for_stripe, I found it actually has 2
usages: for the array to enter or leave the quiescent state, and also
to wait for an available stripe in each of the hash lists.
So this patch splits the first usage off into a separate wait_queue,
wait_for_quiescent, and the next patch will turn the second usage into
one waitqueue for each hash value, and make it exclusive, to relieve
the lock contention.

It's just a variant of wait_event_cmd(), with exclusive flag being set.
For cases like RAID5, which puts many processes to sleep until 1/4
resources are free, a wake_up wakes up all processes to run, but
there is one process being able to get the resource as it's protected
by a spin lock. That ends up introducing heavy lock contentions, and
hurts performance badly.
Here introduce wait_event_exclusive_cmd to relieve the lock contention
naturally by letting wake_up just wake up one process.

This patch adds support for Cavium's ThunderX host controller. The
controller resides on the SoC and is a AHCI compatible SATA controller
with one port, compliant with Serial ATA 3.1 and AHCI Revision 1.31.
There can exists multiple SATA controllers on the SoC.
The controller depends on MSI-X support since the PCI ECAM controller
on the SoC does not implement MSI nor lagacy intx interrupt support.
Thus, during device initialization, if MSI fails MSI-X will be used to
enable the device's interrupts.
The controller uses non-standard BAR0 for its register range. The
already existing device lookup (vendor and device id) that is already
implemented for other host controllers is used to change the PCI BAR.

This patch adds generic MSI-X support for single interrupts to the
SATA PCI driver. MSI-X support is needed for host controller that only
have MSI-X support implemented, but no MSI or intx. This patch only
adds support for single interrupts, multiple per-port MSI-X interrupts
are not yet implemented.
The new implementation still initializes MSIs first. Only if that
fails, the code tries to enable MSI-X. If that fails too, setup is
continued with intx interrupts.
To not break other chips by this generic code change, there are the
following precautions:
* Interrupt ranges are not enabled at all.
* Only single interrupt mode is enabled for msix cap devices. Thus,
only one interrupt will be setup.
* During the discussion with Tejun we agreed to change the init
sequence from msix-msi-intx to msi-msix-intx. Thus, if a device
offers msi and init does not fail, the msix init code will not be
executed. This is equivalent to current code.
With this, the code only setups single mode msix as a last resort if
msi fails. No interrupt range is enabled at all. Only one interrupt
will be enabled.

As of commit 34b1252bd9 ("MIPS:
Cobalt: Do not build MTD platform device registration code as module.")
this file became built-in instead of modular. So we should also
stop using module_init as an alias for __initcall as that can be
rather misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the

Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
And since it can't be modular, we remove all the __exitcall
stuff related to module_exit() -- it is dead code that won't
ever be executed.

The __init_or_module is from commit 05e12e1c4c
("x86: fix 27-rc crash on vsmp due to paravirt during module load").
But as of commit 70511134f6
("Revert "x86: don't compile vsmp_64 for 32bit") this file became
obj-y and hence is now only for built-in. That makes any
"_or_module" support no longer necessary.
We need to distinguish between the two in order to do some header
reorganization between init.h and module.h and we don't want to
be including module.h in non-modular code.

This driver builds based on obj-y and hence will not ever be
modular. Change it to use the non-modular registration so that it
won't suffer a compile fail once a header move places the modular
registration within the module.h file.

This file depends on Kconfig options all of which are a bool, so
we use the appropriate registration function, which avoids us
relying on an implicit inclusion of <module.h> which we are
doing currently.
While this currently works, we really don't want to be including
the module.h header in non-modular code, which we'd be forced
to do, pending some upcoming code relocation from init.h into
module.h. So we fix it now by using the non-modular equivalent.
