On ARM, when a watchpoint is registered using register_wide_hw_breakpoint,
the callback handler endlessly runs until the watchpoint is unregistered.
The reason for this issue is debug interrupts gets raised before executing the
instruction,
and after interrupt

This patch set makes fsl ehci driver as a separate module
from existing ehci-hcd driver. For this, following is done:
- make ehci-fsl.c as a seperate entity by compiling
it separately
- make use of module_init()/module_exit(), and
makeing ehci-fsl.c as tristate
Make fsl ehci driver an independent entity from ehci-hcd driver

Hi,
This is the V2 version of the V1 pathset. But it is just the updated
version of the patch1&2 of the V1 patchset.
[1/5 V1] is split into [1/7 V2] and [2/7 V2].
[2/5 V1] is split into [3,4,5,6,7/7 V2].
[1/7] extends the wq_pool_mutex lock region in the apply_workqueue_attrs().
It is a
tmp_attrs is just temporary attrs, we can use wq_update_unbound_numa_attrs_buf
for it like wq_update_unbound_numa();
This change also avoids frequently alloc/free the tmp_attrs when
the low level cpumask is being updated.

When apply_wqattrs_prepare() is called, it is possible that the default
pwq is unaffected. It is always true that only the NUMA affinity is being
changed and sometimes true that the low level cpumask is being changed.
So we try to reuse the current default pwq when its attrs unchanged.

If the cpuamsk is changed, it is possible that only a part of the per-node

The calculation and allocation of per-node pwq code in
apply_workqueue_attrs() and wq_update_unbound_numa() are highly similar,
we merge them into get_node_unbound_pwq().
wq_calc_node_mask() is only used for this calculation and allocation,
so it is also moved into get_node_unbound_pwq().

wq_update_unbound_numa() is known be called with wq_pool_mutex held.
But wq_update_unbound_numa() requests wq->mutex before reading

were changed to be allowed being read with wq_pool_mutex held. So we

Current wq_pool_mutex doesn't proctect the attrs-installation, it results
that ->unbound_attrs, ->numa_pwq_tbl[] and ->dfl_pwq can only be accessed
under wq->mutex and causes some inconveniences. Example,
wq_update_unbound_numa()
has to acquire wq->mutex before fetching the wq->unbound_attrs->no_n
attrs management code may reuse existed pwq and it has open code
to do "lock();get_pwq();unlock()", we move this open code into
get_pwq_unlocked().
get_pwq_unlocked() will also be used in later patches to allow
apply_wqattrs_prepare() to resue the original default or per-node pwq.

The struct mtk_disp_pwm_chip * is named 'mpc' in the other functions.
For consistency reasons you should do that here aswell.

I'd tend to leave out this debug message. But you may leave it if you
like. Rest of the patch looks okay.
Thanks!

This IP is shared with Watchdog and RTC functionality. All 3 of
these devices are mutually exclusive from one another i.e. Only 1
IP can be used at any given time. We use the device-driver model
combined with a DT 'mode' property to enforce this.

Fam Zheng noticed that pci shutdown disables msi and msix of a device. This
was intended to fix kexec with fusion devices but is no longer necessary, and
can in theory be harmful.
See individual patches for the detailed explanation.
Please review, and consider for 4.2.

d52877c7b1af ("pci/irq: let pci_device_shutdown to call pci_msi_shutdown

The change made by the above commit is no longer necessary: it was
superceded by commit d5dea7d95c48 ("PCI: msi: Disable msi interrupts

ST's Low Power Controller can now operate in three supported modes;
Watchdog, Real Time Clock and most recently as a Clocksource. This new
define will allow the LPC IP to be configured for Clocksource from DT.

The System Configuration (syscon) driver is an important one, which
effects many ARM-SoC based platforms. I'm adding Arnd as a primary
reviewer as he is highly competent in this area and has a keen
interest in ARM-SoC.
