Pull ARM OMAP serial updates from Russell King:
"This series is a major reworking of the OMAP serial driver code fixing
various bugs in the hardware-assisted flow control, extending up into
serial_core for a couple of issues. These fixes have been done as a
set of progressive changes and transformations in the hope that no new
bugs will be introduced by this series.
The problems are many-fold, from the driver not being informed about
updated settings, to the driver not knowing what the intentions of the
upper layers are.
The first four patches tackle the serial_core layer, allowing it to
provide the necessary information to drivers, and the remaining
patches allow the OMAP serial driver to take advantage of this.
This brings hardware assisted RTS/CTS and XON/OFF flow control into a
useful state.
These patches have been in linux-next for most of the last cycle;
indeed they predate the previous merge window. They've also been
posted to the OMAP people."

Add online_movable and online_kernel for logic memory hotplug. This is
the dynamic version of "movablecore" & "kernelcore".
We have the same reason to introduce it as to introduce "movablecore" &
"kernelcore". It has the same motive as "movablecore" & "kernelcore", but
it is dynamic/running-time:
o We can configure memory as kernelcore or movablecore after boot.
Userspace workload is increased, we need more hugepage, we can't use
"online_movable" to add memory and allow the system use more
THP(transparent-huge-page), vice-verse when kernel workload is increase.
Also help for virtualization to dynamic configure host/guest's memory,
to save/(reduce waste) memory.
Memory capacity on Demand
o When a new node is physically online after boot, we need to use
"online_movable" or "online_kernel" to configure/portion it as we
expected when we logic-online it.
This configuration also helps for physically-memory-migrate.
o all benefit as the same as existed "movablecore" & "kernelcore".
o Preparing for movable-node, which is very important for power-saving,
hardware partitioning and high-available-system(hardware fault
management).
(Note, we don't introduce movable-node here.)
Action behavior:
When a memoryblock/memorysection is onlined by "online_movable", the kernel
will not have directly reference to the page of the memoryblock,
thus we can remove that memory any time when needed.
When it is online by "online_kernel", the kernel can use it.
When it is online by "online", the zone type doesn't changed.
Current constraints:
Only the memoryblock which is adjacent to the ZONE_MOVABLE
can be online from ZONE_NORMAL to ZONE_MOVABLE.

It is strange that alloc_bootmem() returns a virtual address and
free_bootmem() requires a physical address. Anyway, free_bootmem()'s
first parameter should be physical address.
There are some call sites for free_bootmem() with virtual address. So fix
them.

The maximum oom_score_adj is 1000 and the minimum oom_score_adj is -1000,
so this range can be represented by the signed short type with no
functional change. The extra space this frees up in struct signal_struct
will be used for per-thread oom kill flags in the next patch.

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.
Besides making balloon pages movable at allocation time and introducing
the necessary primitives to perform balloon page migration/compaction,
this patch also introduces the following locking scheme, in order to
enhance the syncronization methods for accessing elements of struct
virtio_balloon, thus providing protection against concurrent access
introduced by parallel memory migration threads.
- balloon_lock (mutex) : synchronizes the access demand to elements of
struct virtio_balloon and its queue operations;

warning
When calling unregister_node(), the function shows following message at
device_release().
"Device 'node2' does not have a release() function, it is broken and must
be fixed."
The reason is node's device struct does not have a release() function.
So the patch registers node_device_release() to the device's release()
function for suppressing the warning message. Additionally, the patch
adds memset() to initialize a node struct into register_node(). Because
the node struct is part of node_devices[] array and it cannot be freed by
node_device_release(). So if system reuses the node struct, it has a
garbage.

warning
When calling remove_memory_block(), the function shows following message
at device_release().
"Device 'memory528' does not have a release() function, it is broken and
must be fixed."
The reason is memory_block's device struct does not have a release()
function.
So the patch registers memory_block_release() to the device's release()
function for suppressing the warning message. Additionally, the patch
moves kfree(mem) into the release function since the release function is
prepared as a means to free a memory_block struct.

"These are the first and major pinctrl changes for the v3.8 merge
cycle. Some of this is used as merge base for other trees so I better
be early on the trigger.
As can be seen from the diffstat the major changes are:
- A big conversion of the AT91 pinctrl driver and the associated ACKed
platform changes under arch/arm/max-at91 and its device trees. This
has been coordinated with the AT91 maintainers to go in through the
pinctrl tree.
- A larger chunk of changes to the SPEAr drivers and the addition of
the "plgpio" driver for the SPEAr as well.
- The removal of the remnants of the Nomadik driver from the arch/arm
tree and fusion of that into the Nomadik driver and platform data
header files.
- Some local movement in the Marvell MVEBU drivers, these now have
their own subdirectory.
- The addition of a chunk of code to gpiolib under drivers/gpio to
register gpio-to-pin range mappings from the GPIO side of things.
This has been requested by Grant Likely and is now implemented, it
is particularly useful for device tree work.
Then we have incremental updates all over the place, many of these are
cleanups and fixes from Axel Lin who has done a great job of removing
minor mistakes and compilation annoyances."

This commit changes the CMA early initialization code to use phys_addr_t
for representing physical addresses instead of unsigned long.
Without this change, among other things, dma_declare_contiguous() simply
discards any memory regions whose address is not representable as unsigned
long.
This is a problem on 32-bit PAE machines where unsigned long is 32-bit
but physical address space is larger.

Some gate clocks have special needs which must be handled during the
disable-unused clocks sequence. These needs might be driven by software
due to the fact that we're disabling a clock outside of the normal
clk_disable path and a clk's enable_count will not be accurate. On the
other hand a specific hardware programming sequence might need to be
followed for this corner case.
This change is needed for the upcoming OMAP port to the common clock
framework. Specifically, it is undesirable to treat the disable-unused
path identically to the normal clk_disable path since other software
layers are involved. In this case OMAP's clockdomain code throws WARNs
and bails early due to the clock's enable_count being set to zero. A
custom callback mitigates this problem nicely.

mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6
|
|
sdhci-acpi supports ACPI devices which have compatibility ID
PNP0D40, however it is not possible to know if those devices
will all work correctly with runtime-pm, so that must be configured
per hardware ID.
For INT33C6, several related quirks, capabilities and flags are set:
MMC_CAP_NONREMOVABLE
The SDIO card will never be removable
SDHCI_ACPI_RUNTIME_PM
Enable runtime-pm of the host controller
MMC_CAP_POWER_OFF_CARD
Enable runtime-pm of the SDIO card
MMC_PM_KEEP_POWER
SDIO card has the capability to remain powered up
during system suspend
SDHCI_QUIRK2_HOST_OFF_CARD_ON
Always do a full reset during system resume
because the card may be already initialized having
not been powered off.
Wake-ups from the INT33C6 host controller are not supported, so the
following capability must *not* be set:
MMC_PM_WAKE_SDIO_IRQ
Enable wake on card interrupt

This reverts commits a50915394f1fc02c2861d3b7ce7014788aa5066e and
d7c3b937bdf45f0b844400b7bf6fd3ed50bac604.
This is a revert of a revert of a revert. In addition, it reverts the
even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the
original commits in linux-next.
It turns out that the original patch really was bogus, and that the
original revert was the correct thing to do after all. We thought we
had fixed the problem, and then reverted the revert, but the problem
really is fundamental: waking up kswapd simply isn't the right thing to
do, and direct reclaim sometimes simply _is_ the right thing to do.
When certain allocations fail, we simply should try some direct reclaim,
and if that fails, fail the allocation. That's the right thing to do
for THP allocations, which can easily fail, and the GPU allocations want
to do that too.
So starting kswapd is sometimes simply wrong, and removing the flag that
said "don't start kswapd" was a mistake. Let's hope we never revisit
this mistake again - and certainly not this many times ;)
