Commit f70ddc07b6 ("MIPS: c-r4k: Avoid small flush_icache_range SMP
calls") adds checks to force use of hit-type cache ops for small icache
flushes where they are globalised & index-type cache ops aren't, in
order to avoid the overhead of IPIs in those cases. However it
calculated the size of the region being flushed incorrectly, subtracting
the end address from the start address rather than the reverse. This
would have led to an overflow with size wrapping round to some large
value, and likely to the special case for avoiding IPIs not actually
being hit.

A discrepancy between cpu_online_mask and cpuset's effective_cpus
mask is inevitable during hotplug since cpuset defers updating of
effective_cpus mask using a workqueue, during which time nothing
prevents the system from more hotplug operations. For that reason
guarantee_online_cpus() walks up the cpuset hierarchy until it finds
an intersection under the assumption that top cpuset's effective_cpus
mask intersects with cpu_online_mask even with such a race occurring.
However a sequence of CPU hotplugs can open a time window, during which
none of the effective CPUs in the top cpuset intersect with
cpu_online_mask.
For example when there are 4 possible CPUs 0-3 and only CPU0 is online:
======================== ===========================
cpu_online_mask top_cpuset.effective_cpus
======================== ===========================
echo 1 > cpu2/online.
CPU hotplug notifier woke up hotplug work but not yet scheduled.
[0,2] [0]
echo 0 > cpu0/online.
The workqueue is still runnable.
[2] [0]
======================== ===========================
Now there is no intersection between cpu_online_mask and
top_cpuset.effective_cpus. Thus invoking sys_sched_setaffinity() at
this moment can cause following:
Unable to handle kernel NULL pointer dereference at virtual address 000000d0

The top cpuset's effective_cpus are guaranteed to be identical to
cpu_online_mask eventually. Hence fall back to cpu_online_mask when
there is no intersection between top cpuset's effective_cpus and
cpu_online_mask.

If dma_pfn_offset is not inherited correctly from the host controller,
it might result in sub-optimal configuration as bounce
buffer limit might be set to less than optimal level.
Consider the mass storage device case.
USB storage driver creates a scsi host for the mass storage interface in
drivers/usb/storage/usb.c
The scsi host parent device is nothing but the the USB interface device.
Now, __scsi_init_queue() calls scsi_calculate_bounce_limit() to find out
and set the block layer bounce limit.
scsi_calculate_bounce_limit() uses dma_max_pfn(host_dev) to get the
bounce_limit. host_dev is nothing but the device representing the
mass storage interface.
If that device doesn't have the right dma_pfn_offset, then dma_max_pfn()
is messed up and the bounce buffer limit is wrong.
e.g. On Keystone 2 systems, dma_max_pfn() is 0x87FFFF and dma_mask_pfn
is 0xFFFFF. Consider a mass storage use case: Without this patch,
usb scsi host device (usb-storage) will get a dma_pfn_offset of 0 resulting
in a dma_max_pfn() of 0xFFFFF within the scsi layer
(scsi_calculate_bounce_limit()).
This will result in bounce buffers being unnecessarily used.
Hint: On 32-bit ARM platforms dma_max_pfn() = dma_mask_pfn + dma_pfn_offset

When system enters into kdump kernel because of kernel panic, it won't
shutdown devices. On-flight DMA will continue transferring data until
device driver initializes. All devices are supposed to reset during
driver initialization. And this property is used to fix the kdump
failure in system with intel iommu. Other systems with hardware iommu
should be similar. Please check commit 091d42e ("iommu/vt-d: Copy
translation tables from old kernel") and those commits around.
But bnx2 driver doesn't reset device during driver initialization. The
device resetting is deferred to net device up stage. This will cause
hardware iommu handling failure on bnx2 device. And its resetting relies
on firmware. So in this patch move the firmware requesting code to earlier
bnx2_init_one(), then next call bnx2_reset_chip to reset device.

If /sbin/bridge-stp is available on the system, bridge tries to execute
it instead of the kernel implementation when starting/stopping STP.
If anything goes wrong with /sbin/bridge-stp, bridge silently falls back
to kernel STP, making hard to debug userspace STP.
This patch adds a br_stp_call_user helper to start/stop userspace STP
and debug errors from the program: abnormal exit status is stored in the
lower byte and normal exit status is stored in higher byte.
Below is a simple example on a kernel with dynamic debug enabled:
# ln -s /bin/false /sbin/bridge-stp
# brctl stp br0 on
br0: failed to start userspace STP (256)
# dmesg
br0: /sbin/bridge-stp exited with code 1

With musb core now blocking PM based on the devctl status
bit, we can remove related quirks from the 2430 glue layer
and simplify PM runtime further.
Lets's also use musb->controller instead of dev to make it
clear we make the PM runtime calls for the core, not the
glue layer.
And we can now also lower the autoidle timeout.

We want to be polling the state when nothing is connected.
Let's change the polling logic in preparation for PM runtime

We want to keep musb enabled always when the session bit is
set. This simplifies the PM runtime and allows making it more
generic across the various glue layers.
So far the only exception to just following the session bit is
host mode disconnect where the session bit stays set.
In that case, just allow PM and let the PM runtime autoidle
timeout deal with it.

Detailed description for this pull request:
1. Support the extcon property and add the synchronization APIs.
- This feature supports the extcon property for external connector
because each external connector might have the property according to
the H/W design.
- The property name should keep the following style.
: EXTCON_PROP_USB_[property_name]
: EXTCON_PROP_CHG_[property_name]
: EXTCON_PROP_JACK_[property_name]
: EXTCON_PROP_DISP_[property_name]
- Add the new extcon APIs to support the extcon property.
: extcon_set_property()
: extcon_get_property()
: extcon_set_property_capability()
: extcon_get_property_capability()
- Add the new synchronization extcon APIs.
: This feature adds the synchronization extcon APIs to support the noti
for both state and property. When extcon_*_sync() functions is called,
the extcon informs the information from extcon provider to extcon client.
The extcon driver may need to change the both state and multiple properties
at the same time. After setting the data of a external connector,
the extcon send the notification to client driver with the extcon_*_sync().
: extcon_sync()
: extcon_set_state_sync()
: extcon_set_property_sync()
- Change the name of existing APIs.
: extcon_set_cable_state_() -> extcon_set_cable()
: extcon_get_cable_state_() -> extcon_get_cable()
2. Add the extcon type to group the connector into five category.
- EXTCON_TYPE_USB : USB connector
- EXTCON_TYPE_CHG : Charger connector
- EXTCON_TYPE_JACK : Jack connector
- EXTCON_TYPE_DISP : Display connector
- EXTCON_TYPE_MISC : Miscellaneous connector
3. Add the new property for external connector.
- EXTCON_PROP_USB_VBUS
- EXTCON_PROP_USB_TYPEC_POLARITY
- EXTCON_PROP_USB_SS (SuperSpeed)
- EXTCON_PROP_DISP_HPD (Hot Plug Detect)
4. Add the new type of external connector.
- EXTCON_DISP_DP : Display Port
- EXTCON_DISP_HMD : Head Mounted Device
- EXTCON_CHG_WPT : Wireless Power Transfer device
5. Add the new extcon driver.
- Qualcomm SPMI PMIC USB id detection driver detects whether
EXTCON_USB_HOST is attached or detached. (extcon-qcom-spmi-mis.c)
6. Remove the usage of extcon_update_state() and old extcon_set_state()
- Both extcon_update_state() and extcon_set_state() should change the state
of all external connectors with bit masking handling. It may occur the
problem. Instead, extcon provides the extcon_set/get_state() functions.
7. Fix the minor issues on extcon drivers.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Endianess fix for the new nf_tables netlink trace infrastructure,
NFTA_TRACE_POLICY endianess was not correct, patch from Liping Zhang.
2) Fix broken re-route after userspace queueing in nf_tables route
chain. This patch is large but it is simple since it is just getting
this code in sync with iptable_mangle. Also from Liping.
3) NAT mangling via ctnetlink lies to userspace when nf_nat_setup_info()
fails to setup the NAT conntrack extension. This problem has been
there since the beginning, but it can now show up after rhashtable
conversion.
4) Fix possible NULL pointer dereference due to failures in allocating
the synproxy and seqadj conntrack extensions, from Gao feng.

aic5_irq_domain_xlate() and aic_irq_domain_xlate() take the generic chip
lock without disabling interrupts, which can lead to a deadlock if an
interrupt occurs while the lock is held in one of these functions.
Replace irq_gc_{lock,unlock}() calls by
irq_gc_{lock_irqsave,unlock_irqrestore}() ones to prevent this bug from
happening.

Some irqchip drivers need to take the generic chip lock outside of the
irq context.
Provide the irq_gc_{lock_irqsave,unlock_irqrestore}() helpers to allow
one to disable irqs while entering a critical section protected by
gc->lock.
Note that we do not provide optimized version of these helpers for !SMP,
because they are not called from the hot-path.

As we only install the callback once, the overhead comes from the atomic

Currently the label says "Core" but lists the thread numbers. This
ends up looking like this:
# cat /sys/class/hwmon/hwmon0/temp[1-4]_label
Core 0-7
Core 8-15
Core 16-23
Core 24-31
This is misleading as it looks like it's cores 0-7 when it's actually
threads 0-7.
This changes the print to just give the core number, so the output now
looks like this:
# cat /sys/class/hwmon/hwmon0/temp[1-4]_label
Core 0
Core 8
Core 16
Core 24
