Linux xHCI driver doesn't report and handle port cofig error change.
If Port Configure Error for root hub port occurs, CEC bit in PORTSC
would be set by xHC and remains 1. This happends when the root port
fails to configure its link partner, e.g. the port fails to exchange
port capabilities information using Port Capability LMPs.
Then the Port Status Change Events will be blocked until all status
change bits(CEC is one of the change bits) are cleared('0') (refer to
xHCI spec 4.19.2). Otherwise, the port status change event for this
root port will not be generated anymore, then root port would look
like dead for user and can't be recovered until a Host Controller
Reset(HCRST).
This patch is to check CEC bit in PORTSC in xhci_get_port_status()
and set a Config Error in the return status if CEC is set. This will
cause a ClearPortFeature request, where CEC bit is cleared in
xhci_clear_port_change_bit().

Implement the recommendation from the BCM2835 data-sheet
with regards to polling drivers to fill/drain the FIFO as much data as possible
also for the interrupt-driven case (which this driver is making use of).
This means that for long transfers (>64bytes) we need one interrupt
every 64 bytes instead of every 12 bytes, as the FIFO is 16 words (not bytes) wide.
Tested with mcp251x (can bus), fb_st7735 (TFT framebuffer device)
and enc28j60 (ethernet) drivers.

Its ClickPad shares PNP ID "LEN2006" with the one in model E540 which is
already handled by the driver (both are Haswell iterations of the Edge
line, launched in 2014) but the dimensions it reports are different:
$ sudo ./touchpad-edge-detector /dev/input/event3
Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event3
Move one finger around the touchpad to detect the actual edges
Kernel says: x [1472..5044], y [1408..3398]
Touchpad sends: x [1024..5045], y [2457..4832] /^C
Fortunately we can use the board ID, which is also different, to
distinguish among them.

Firstly, handle zero length calls properly. Believe it or not there
are a few of these happening during early boot.
Next, we can't just drop to a memcpy() call in the forward copy case
where dst <= src. The reason is that the cache initializing stores
used in the Niagara memcpy() implementations can end up clearing out
cache lines before we've sourced their original contents completely.
For example, considering NG4memcpy, the main unrolled loop begins like
this:
load src + 0x00
load src + 0x08
load src + 0x10
load src + 0x18
load src + 0x20
store dst + 0x00
Assume dst is 64 byte aligned and let's say that dst is src - 8 for
this memcpy() call. That store at the end there is the one to the
first line in the cache line, thus clearing the whole line, which thus
clobbers "src + 0x28" before it even gets loaded.
To avoid this, just fall through to a simple copy only mildly
optimized for the case where src and dst are 8 byte aligned and the
length is a multiple of 8 as well. We could get fancy and call
GENmemcpy() but this is good enough for how this thing is actually
used.

From 1ebf33901ecc75d9496862dceb1ef0377980587c Mon Sep 17 00:00:00 2001
From: Tejun Heo <tj@kernel.org>
Date: Mon, 23 Mar 2015 00:08:19 -0400
2f800fbd777b ("writeback: fix dirtied pages accounting on redirty")
introduced account_page_redirty() which reverts stat updates for a
redirtied page, making BDI_DIRTIED no longer monotonically increasing.
bdi_update_write_bandwidth() uses the delta in BDI_DIRTIED as the
basis for bandwidth calculation. While unlikely, since the above
patch, the newer value may be lower than the recorded past value and
underflow the bandwidth calculation leading to a wild result.
Fix it by subtracing min of the old and new values when calculating
delta. AFAIK, there hasn't been any report of it happening but the
resulting erratic behavior would be non-critical and temporary, so
it's possible that the issue is happening without being reported. The
risk of the fix is very low, so tagged for -stable.

Commit 054954eb051f35e74b75a566a96fe756015352c8 ("xen: switch to linear
virtual mapped sparse p2m list") introduced a regression regarding to
memory hotplug for a pv-domain: as the virtual space for the p2m list
is allocated for the to be expected memory size of the domain only,
hotplugged memory above that size will not be usable by the domain.
Correct this by using a configurable size for the p2m list in case of
memory hotplug enabled (default supported memory size is 512 GB for
64 bit domains and 4 GB for 32 bit domains).

Device domains never span IOMMU hardware units, which allows the
domain ID space for each IOMMU to be an independent address space.
Therefore we can have multiple, independent domains, each with the
same domain->id, but attached to different hardware units. This is
also why we need to do a heavy-weight search for VM domains since
they can span multiple IOMMUs hardware units and we don't require a
single global ID to use for all hardware units.
Therefore, if we call iommu_detach_domain() across all active IOMMU
hardware units for a non-VM domain, the result is that we clear domain
IDs that are not associated with our domain, allowing them to be
re-allocated and causing apparent coherency issues when the device
cannot access IOVAs for the intended domain.
This bug was introduced in commit fb170fb4c548 ("iommu/vt-d: Introduce
helper functions to make code symmetric for readability"), but is
significantly exacerbated by the more recent commit 62c22167dd70
("iommu/vt-d: Fix dmar_domain leak in iommu_attach_device") which calls
domain_exit() more frequently to resolve a domain leak.

It turns out that these issues have nothing to do with using sdio-irq support,

add MMC_CAP_SDIO_IRQ to the default host caps.

Struct tmio_mmc_host is embedded inside struct mmc_host, and thus is
freed by the call to mmc_free_host(). Hence it must not be written to
afterwards, as that will corrupt freed (and perhaps already reused)
memory.

Setting a dev_pm_ops suspend/resume pair but not a set of
hibernation functions means those pm functions will not be
called upon hibernation.
Fix this by using SET_SYSTEM_SLEEP_PM_OPS, which appropriately
assigns the suspend and hibernation handlers and move
omap_hsmmc_x callbacks under CONFIG_PM_SLEEP to avoid build warnings.
