Use the proper format for FE_SET_VOLTAGE documentation and fix
the documentation. The description for the enum is not 100%,
and it is missing the voltage off value.
Also, it is better to keep the enum description together with
the ioctl, as both are used together.

Using typedefs is already bad enough, but doing it together
with enum declaration is even worse.
Also, it breaks the scripts at DocBook that would be generating
reference pointers for the enums.
Well, we can't get rid of typedef right now, but let's at least
declare it on a separate line, and let the scripts to generate
the cross-reference, as this is needed for the next DocBook
patches.

Looks like I only built test the dev_pm_set_wake_irq and not the
dev_pm_set_dedicated_wake_irq case on x86.
Turns out there's a typo for the dev_pm_set_dedicated_wake_irq
prototype that causes a build error if CONFIG_COMPILE_TEST
and CONFIG_MMC_OMAP_HS are selected.

David Ahern reported that d63e2e1f3df9 ("sparc/PCI: Clip bridge windows
to fit in upstream windows") fails to boot on sparc/T5-8:
pci 0000:06:00.0: reg 0x184: can't handle BAR above 4GB (bus address 0x110204000)
The problem is that sparc64 assumed that dma_addr_t only needed to hold DMA
addresses, i.e., bus addresses returned via the DMA API (dma_map_single(),
etc.), while the PCI core assumed dma_addr_t could hold *any* bus address,
including raw BAR values. On sparc64, all DMA addresses fit in 32 bits, so
dma_addr_t is a 32-bit type. However, BAR values can be 64 bits wide, so
they don't fit in a dma_addr_t. d63e2e1f3df9 added new checking that
tripped over this mismatch.
Add pci_bus_addr_t, which is wide enough to hold any PCI bus address,
including both raw BAR values and DMA addresses. This will be 64 bits
on 64-bit platforms and on platforms with a 64-bit dma_addr_t. Then
dma_addr_t only needs to be wide enough to hold addresses from the DMA API.

least as wide as dma_addr_t, documentation]

Recent header file changes for cgroup caused lots of warnings
about a missing struct seq_file form declaration for every
inclusion of include/linux/cgroup-defs.h.
As some files are built with -Werror, this leads to build
failure like:

XFS uses non-stanard batch sizes for avoiding frequent global
counter updates on it's allocated inode counters, as they increment
or decrement in batches of 64 inodes. Hence the standard percpu
counter batch of 32 means that the counter is effectively a global
counter. Currently Xfs uses a batch size of 128 so that it doesn't
take the global lock on every single modification.
However, Xfs also needs to compare accurately against zero, which
means we need to use percpu_counter_compare(), and that has a
hard-coded batch size of 32, and hence will spuriously fail to
detect when it is supposed to use precise comparisons and hence
the accounting goes wrong.
Add __percpu_counter_compare() to take a custom batch size so we can
use it sanely in XFS and factor percpu_counter_compare() to use it.

The tracing_off_permanent() call is a way to disable all ring_buffers.
Nothing uses it and nothing should use it, as tracing_off() and
friends are better, as they disable the ring buffers related to
tracing. The tracing_off_permanent() even disabled non tracing
ring buffers. This is a bit drastic, and was added to handle NMIs
doing outputs that could corrupt the ring buffer when only tracing
used them. It is now obsolete and adds a little overhead, it should
be removed.

bdi_unregister() now contains very little functionality.
It contains a "WARN_ON" if bdi->dev is NULL. This warning is of no
real consequence as bdi->dev isn't needed by anything else in the function,
and it triggers if
blk_cleanup_queue() -> bdi_destroy()
is called before bdi_unregister, which happens since
Commit: 6cd18e711dd8 ("block: destroy bdi before blockdev is unregistered.")
So this isn't wanted.
It also calls bdi_set_min_ratio(). This needs to be called after
writes through the bdi have all been flushed, and before the bdi is destroyed.
Calling it early is better than calling it late as it frees up a global
resource.
Calling it immediately after bdi_wb_shutdown() in bdi_destroy()
perfectly fits these requirements.
So bdi_unregister() can be discarded with the important content moved to
bdi_destroy(), as can the
writeback_bdi_unregister
event which is already not used.

Fix the comments comments accordingly. Added a couple of other small
comment fixes while I was there to silence other recently-added docbook
warnings.

The ring_cookie is 64 bits wide which is much larger than can be used
for actual queue index values. So provide some helper routines to
pack a VF index into the cookie. This is useful to steer packets to
a VF ring without having to know the queue layout of the device.

This commit introduces a variant of the mv_mbus_dram_info() function
called mv_mbus_dram_info_nooverlap(). Both functions are used by
Marvell drivers supporting devices doing DMA, and provide them a
description the DRAM ranges that they need to configure their DRAM
windows.
The ranges provided by the mv_mbus_dram_info() function may overlap
with the I/O windows if there is a lot (>= 4 GB) of RAM
installed. This is not a problem for most of the DMA masters, except
for the upcoming new CESA crypto driver because it does DMA to the
SRAM, which is mapped through an I/O window. For this unit, we need to
have DRAM ranges that do not overlap with the I/O windows.
A first implementation done in commit 1737cac69369 ("bus: mvebu-mbus:
make sure SDRAM CS for DMA don't overlap the MBus bridge window"),
changed the information returned by mv_mbus_dram_info() to match this
requirement. However, it broke the requirement of the other DMA
masters than the DRAM ranges should have power of two sizes.
To solve this situation, this commit introduces a new
mv_mbus_dram_info_nooverlap() function, which returns the same
information as mv_mbus_dram_info(), but guaranteed to not overlap with
the I/O windows.
In the end, it gives us two variants of the mv_mbus_dram_info*()
functions:
- The normal one, mv_mbus_dram_info(), which has been around for many
years. This function returns the raw DRAM ranges, which are
guaranteed to use power of two sizes, but will overlap with I/O
windows. This function will therefore be used by all DMA masters
(SATA, XOR, Ethernet, etc.) except the CESA crypto driver.
- The new 'nooverlap' variant, mv_mbus_dram_info_nooverlap(). This
function returns DRAM ranges after they have been "tweaked" to make
sure they don't overlap with I/O windows. By doing this tweaking,
we remove the power of two size guarantee. This variant will be
used by the new CESA crypto driver.

The memory slot is already available from gfn_to_memslot_dirty_bitmap.
Isn't it a shame to look it up again? Plus, it makes gfn_to_page_many_atomic
agnostic of multiple VCPU address spaces.

This lets the function access the new memory slot without going through
kvm_memslots and id_to_memslot. It will simplify the code when more
than one address space will be supported.
Unfortunately, the "const"ness of the new argument must be casted
away in two places. Fixing KVM to accept const struct kvm_memory_slot
pointers would require modifications in pretty much all architectures,
and is left for later.

This patch adds IV generator information for each AEAD and block
cipher to xfrm_algo_desc. This will be used to access the new
AEAD interface.

This patch adds some common IV generation code currently duplicated
by seqiv and echainiv. For example, the setkey and setauthsize
functions are completely identical.

This patch defines the behaviour of AD in the new interface more
clearly. In particular, it specifies that if the user must copy
the AD to the destination manually when src != dst if they wish
to guarantee that the destination buffer contains a copy of the
AD.
The reason for this is that otherwise every AEAD implementation
would have to perform such a copy when src != dst. In reality
most users do in-place processing where src == dst so this is
not an issue.
This patch also kills some remaining references to cryptoff.

Merge the crypto tree for 4.1 to pull in the changeset that disables
algif_aead.

This takes out the bool_enable_only implementation from
the module loading code and generalizes it so that others
can make use of it.

Most code already uses consts for the struct kernel_param_ops,
sweep the kernel for the last offending stragglers. Other than
include/linux/moduleparam.h and kernel/params.c all other changes
were generated with the following Coccinelle SmPL patch. Merge
conflicts between trees can be handled with Coccinelle.
In the future git could get Coccinelle merge support to deal with
patch --> fail --> grammar --> Coccinelle --> new patch conflicts
automatically for us on patches where the grammar is available and
the patch is of high confidence. Consider this a feature request.
