The LTR is the handshake between the device and the root
complex about the latency allowed when the bus exits power
save. This configuration was missing and this led to high
latency in the link power up. The end user could experience
high latency in the network because of this.

Many AP devices do not have the proper regulatory domain programmed in
EEPROM. Instead they expect the software to set the appropriate region.
For these devices, the country code defaults to US, and the driver uses
the US CTL tables as well.
On devices bought in Europe this can lead to tx power being set too high
on the band edges, even if the cfg80211 regdomain is set correctly.
Fix this issue by taking into account the DFS region, but only when the
EEPROM regdomain is set to default.

When a new p2m leaf is allocated this leaf is linked into the p2m tree
via cmpxchg. Unfortunately the compare value for checking the success
of the update is read after checking for the need of a new leaf. It is
possible that a new leaf has been linked into the tree concurrently
in between. This could lead to a leaked memory page and to the loss of
some p2m entries.
Avoid the race by using the read compare value for checking the need
of a new p2m leaf and use ACCESS_ONCE() to get it.
There are other places which seem to need ACCESS_ONCE() to ensure
proper operation. Change them accordingly.

The 3 level p2m tree for the Xen tools is constructed very early at
boot by calling xen_build_mfn_list_list(). Memory needed for this tree
is allocated via extend_brk().
As this tree (other than the kernel internal p2m tree) is only needed
for domain save/restore, live migration and crash dump analysis it
doesn't matter whether it is constructed very early or just some
milliseconds later when memory allocation is possible by other means.
This patch moves the call of xen_build_mfn_list_list() just after
calling xen_pagetable_p2m_copy() simplifying this function, too, as it
doesn't have to bother with two parallel trees now. The same applies
for some other internal functions.
While simplifying code, make early_can_reuse_p2m_middle() static and
drop the unused second parameter. p2m_mid_identity_mfn can be removed
as well, it isn't used either.

that a parent's ->suspend() will only be called after all
children are suspended. dwc3-omap is the parent of the

2) When implementing Deep Sleep states where context is lost,
USBOTGSS_IRQ0 register, well, looses context so we
_must_ rewrite it otherwise core IRQs will never be

commit c58d80f52 ("usb: musb: Ensure that cppi41 timer gets armed on

which does not trigger that often.
The following scenario is still possible:
lock(&x->lock);
hrtimer_start(&x->t);
unlock(&x->lock);
expires:
t->function();
lock(&x->lock);
lock(&x->lock); if (!hrtimer_queued(&x->t))
hrtimer_start(&x->t);
unlock(&x->lock);
if (!list_empty(x->early_tx_list))
ret = HRTIMER_RESTART;
-> hrtimer_forward_now(...)
} else
ret = HRTIMER_NORESTART;
unlock(&x->lock);
and the timer callback returns HRTIMER_RESTART for an armed timer. This
is wrong and we run into the BUG_ON() in __run_hrtimer().
This can happens on SMP or PREEMPT-RT.
The patch fixes the problem by only starting the timer if the timer is
not yet queued.

"

A control pipe may have a variable-length data phase
in which the host requests more data than is contained
in the specified data structure. When all of the data
structure is returned to the host, the function should
indicate that the Data stage is ended by returning a
packet that is shorter than the MaxPacketSize for the
pipe. If the data structure is an exact multiple of
wMaxPacketSize for the pipe, the function will return
a zero-length packet to indicate the end of the Data

Commit dd56af42bd (rcu: Eliminate deadlock between CPU hotplug and
expedited grace periods) was incomplete. Although it did eliminate
deadlocks involving synchronize_sched_expedited()'s acquisition of
cpu_hotplug.lock via get_online_cpus(), it did nothing about the similar
deadlock involving acquisition of this same lock via put_online_cpus().
This deadlock became apparent with testing involving hibernation.
This commit therefore changes put_online_cpus() acquisition of this lock
to be conditional, and increments a new cpu_hotplug.puts_pending field
in case of acquisition failure. Then cpu_hotplug_begin() checks for this
new field being non-zero, and applies any changes to cpu_hotplug.refcount.

An official recent Windows driver from FTDI detects counterfeit devices
and reprograms the internal EEPROM containing the USB PID to 0, effectively
bricking the device.
Add support for this VID/PID pair to correctly bind the driver on these
devices.

Currently, we can't call opal wrappers from modules when using the LE
ABIv2, which requires a TOC init. If we do we'll try and load the opal
entry point using the wrong toc and probably explode or worse jump to
the wrong address.
Nothing in upstream is making opal calls from a module, but we do export
one of the wrappers so we should fix this anyway.
This change uses the _GLOBAL_TOC() macro (rather than _GLOBAL) for the
opal wrappers, so that we can do non-local calls to them.

When sg_scsi_ioctl() fails to prepare request to submit in
blk_rq_map_kern() we jump to a label where we just end up copying
(luckily zeroed-out) kernel buffer to userspace instead of reporting
error. Fix the problem by jumping to the right label.

Without the 3.3V regulator node, the SDMMC driver will give these warnings:
dw_mmc ff704000.dwmmc0: No vmmc regulator found
dw_mmc ff704000.dwmmc0: No vqmmc regulator found
This patch adds the regulator node, and points the SD/MMC to the regulator.

v3: Rename nodes to have schematic-name_regulator and remove "boot-on" and
"always-on"
v2: Move the regulator nodes to their respective board dts file and
correctly rename them to match the schematic
