trace_spmi_write_begin() and trace_spmi_read_end() both call
memcpy() with a length of "len + 1". This leads to one extra
byte being read beyond the end of the specified buffer. Fix
this out-of-bound memory access by using a length of "len"
instead.
Here is a KASAN log showing the issue:

When the target process is busy, incoming oneway transactions are
queued in the async_todo list. If the clients continue sending extra
oneway transactions while the target process is frozen, this queue can
become too large to accommodate new transactions. That's why binder
driver introduced ONEWAY_SPAM_DETECTION to detect this situation. It's
helpful to debug the async binder buffer exhausting issue, but the
issue itself isn't solved directly.
In real cases applications are designed to send oneway transactions
repeatedly, delivering updated inforamtion to the target process.
Typical examples are Wi-Fi signal strength and some real time sensor
data. Even if the apps might only care about the lastet information,
all outdated oneway transactions are still accumulated there until the
frozen process is thawed later. For this kind of situations, there's
no existing method to skip those outdated transactions and deliver the
latest one only.
This patch introduces a new transaction flag TF_UPDATE_TXN. To use it,
use apps can set this new flag along with TF_ONE_WAY. When such an
oneway transaction is to be queued into the async_todo list of a frozen
process, binder driver will check if any previous pending transactions
can be superseded by comparing their code, flags and target node. If
such an outdated pending transaction is found, the latest transaction
will supersede that outdated one. This effectively prevents the async
binder buffer running out and saves unnecessary binder read workloads.

When many devices share the same iova domain, iommu_dma_init_domain()
may be called at the same time. The checking of iovad->start_pfn will
all get false in iommu_dma_init_domain() and both enter init_iova_domain()
to do iovad initialization.
Fix this by protecting init_iova_domain() with iommu_dma_cookie->mutex.

The current check only worked for AP mode, but we can do
radar detection in mesh as well (for example). We could
try to check this using wdev_chandef(), but we also don't
really care since the chandef is passed in and we have no
need to use it anymore (since we added the argument in
commit d2859df5e7 ("cfg80211/mac80211: DFS setup chandef

In many cases we might get here from driver code that's
not really set up to care about the locking, and for the
non-MLO cases we really don't care so much about it. So
relax the checking here for now, perhaps we should even
remove it completely since we might not really care if
we point to an invalid link's chandef and can require
the caller to check the link validity first.

Currently the VBUS/ID detection interrupts are disabled during system
suspend. So the USB cable connect/disconnect event can't wakeup the
system from low power mode. To allow this, we keep these interrupts
enabled and configure them as wakeup capable. This behavior can be
controlled through device wakeup source policy by the user space.
This was tested and verified on a target.

trace_android_vh_binder_proc_transaction_entry:
We need change binder thread so that this work can be added in
proc->todo, if we found the binder thread, skip native logic.
trace_android_vh_binder_select_worklist_ilocked:
we need this because we can't change list point in ”trace_android_vh_binder_thread_read“,
otherwise, If a work has beed added in our own defined list before,
current may goto retry and loop again and again.

The following commits added support for printing the real address-
65875073ed ("net: use %px to print skb address in trace_netif_receive_skb")
70713dddf3 ("net_sched: introduce tracepoint trace_qdisc_enqueue()")
851f36e409 ("net_sched: use %px to print skb address in trace_qdisc_dequeue()")
However, tracing the packet traversal shows a mix of hashes and real
addresses. Pasting a sample trace for reference-

Switch the trace print formats to %p for all the events to have a
consistent format of printing the hashed addresses in all cases.

This change adds vendor hook for gic-v2 resume to allow vendor GIC
enhancement. This is inline with hook present today in irq-gic-v3.c
with one difference that vendor hooks in v2 driver do not pass entire
gic_chip_data struct to vendor module. Instead it passes the required
fields which are irq_domain and the gic dist base to know the wakeup
IRQ reason.
The newly added vendor hook can get invoked by two ways.
1. By registering with syscore ops, .resume method can invoke vendor
hook. This is applicable for cases like suspend-to-ram which
invokes syscore ops.
2. By exporting the gic_v2_resume(), the newly added vendor hook will
get invoked during the first CPU waking up from suspend-to-idle
case.
While at this move android_vh_gic_resume() to gic_v3.h as its specific
to v3 driver.

android_vh_audio_usb_offload_suspend:
To skip pcm suspend in offload mode
We need a vendor hook to skip usb audio suspend in offload mode.
In kernel5.4 the cmd SNDRV_PCM_TRIGGER_SUSPEND and SNDRV_PCM_TRIGGER_STOP are treated differently.
However, they are treated the same in kernel5.15, which will lead to system suspend while music playing in offload mode.
