After commit f5ff79fddf0e ("dma-mapping: remove CONFIG_DMA_REMAP") there's
a chance of DMA buffer getting allocated via vmalloc(), which messes up
the mmapping code:
> RIP: msc_mmap_fault [intel_th_msu]
> Call Trace:
> <TASK>
> __do_fault
> do_fault
...
Fix this by accounting for vmalloc possibility.

cycles on freeing/allocating skbuff_heads on every new Rx or completed
Tx.
Use napi_consume_skb() to feed the cache with skbuff_heads of completed
Tx, so it's never empty. The budget parameter is added to indicate NAPI

TCP allocates 'fast clones' skbs for packets in tx queues.
Currently, __alloc_skb() initializes the companion fclone
field to SKB_FCLONE_CLONE, and leaves other fields untouched.
It makes sense to defer this init much later in skb_clone(),
because all fclone fields are copied and hot in cpu caches
at that time.
This removes one cache line miss in __alloc_skb(), cost seen
on an host with 256 cpus all competing on memory accesses.

Sudeep writes:
cacheinfo and arch_topology updates for v5.20
These are updates to fix some discrepancies we have in the CPU topology
parsing from the device tree /cpu-map node and the divergence from the
behaviour on a ACPI enabled platform. The expectation is that both DT
and ACPI enabled systems must present consistent view of the CPU topology.
The current assignment of generated cluster count as the physical package
identifier for each CPU is wrong. The device tree bindings for CPU
topology supports sockets to infer the socket or physical package
identifier for a given CPU. It is now being made use of you address the
issue. These updates also assigns the cluster identifier as parsed from
the device tree cluster nodes within /cpu-map without support for
nesting of the clusters as there are no such reported/known platforms.
In order to be on par with ACPI PPTT physical package/socket support,
these updates also include support for socket nodes in /cpu-map.
The only exception is that the last level cache id information can be
inferred from the same ACPI PPTT while we need to parse CPU cache nodes
in the device tree. The cacheinfo changes here is to enable the re-use
of the cacheinfo to detect the cache attributes for all the CPU quite
early even before the scondardaries are booted so that the information
can be used to build the schedular domains especially the last level
cache(LLC).

There is a race in pty_write(). pty_write() can be called in parallel
with e.g. ioctl(TIOCSTI) or ioctl(TCXONC) which also inserts chars to
the buffer. Provided, tty_flip_buffer_push() in pty_write() is called
outside the lock, it can commit inconsistent tail. This can lead to out
of bounds writes and other issues. See the Link below.
To fix this, we have to introduce a new helper called
tty_insert_flip_string_and_push_buffer(). It does both
tty_insert_flip_string() and tty_flip_buffer_commit() under the port
lock. It also calls queue_work(), but outside the lock. See
71a174b39f10 (pty: do tty_flip_buffer_push without port->lock in
pty_write) for the reasons.
Keep the helper internal-only (in drivers' tty.h). It is not intended to
be used widely.

TLB sync timeouts can be due to various reasons such as TBU power down
or pending TCU/TBU invalidation/sync and so on. Debugging these often
require dumping of some implementation defined registers to know the
status of TBU/TCU operations and some of these registers are not
accessible in non-secure world such as from kernel and requires SMC
calls to read them in the secure world. So, add this debug support
to dump implementation defined registers for TLB sync timeout issues.

The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.3.3 defines the DM response. There exists
no DM command. However, the current implementation incorrectly sends DM as
command in case of unexpected UIH frames in gsm_queue().
Correct this behavior by always sending DM as response.

Some Freescale 8250 implementations have the problem that a single long
break results in one irq per character frame time. The code in
fsl8250_handle_irq() that is supposed to handle that uses the BI bit in
lsr_saved_flags to detect such a situation and then skip the second
received character. However it also stores other error bits and so after
a single frame error the character received in the next irq handling is
passed to the upper layer with a frame error, too.
So after a spike on the data line (which is correctly recognized as a
frame error) the following valid character is thrown away, because the
driver reports a frame error for that one, too.
To weaken this problem restrict saving LSR to only the BI bit.
Note however that the handling is still broken:
- lsr_saved_flags is updated using orig_lsr which is the LSR content
for the first received char, but there might be more in the FIFO, so
a character is thrown away that is received later and not necessarily
the one following the break.
- The doubled break might be the 2nd and 3rd char in the FIFO, so the
workaround doesn't catch these, because serial8250_rx_chars() doesn't
handle the workaround.
- lsr_saved_flags might have set UART_LSR_BI at the entry of
fsl8250_handle_irq() which doesn't originate from
fsl8250_handle_irq()'s "up->lsr_saved_flags |= orig_lsr &
UART_LSR_BI;" but from e.g. from serial8250_tx_empty().
- For a long or a short break this isn't about two characters, but more
or only a single one.

The main issue this driver addresses is that a USB hub needs to be
powered before it can be discovered. For discrete onboard hubs (an
example for such a hub is the Realtek RTS5411) this is often solved
by supplying the hub with an 'always-on' regulator, which is kind
of a hack. Some onboard hubs may require further initialization
steps, like changing the state of a GPIO or enabling a clock, which
requires even more hacks. This driver creates a platform device
representing the hub which performs the necessary initialization.
Currently it only supports switching on a single regulator, support
for multiple regulators or other actions can be added as needed.
Different initialization sequences can be supported based on the
compatible string.
Besides performing the initialization the driver can be configured
to power the hub off during system suspend. This can help to extend
battery life on battery powered devices which have no requirements
to keep the hub powered during suspend. The driver can also be
configured to leave the hub powered when a wakeup capable USB device
is connected when suspending, and power it off otherwise.
Technically the driver consists of two drivers, the platform driver
described above and a very thin USB driver that subclasses the
generic driver. The purpose of this driver is to provide the platform
driver with the USB devices corresponding to the hub(s) (a hub
controller may provide multiple 'logical' hubs, e.g. one to support
USB 2.0 and another for USB 3.x).

There are no upstream users of the 'companion-hub' property, neither in
the device tree, nor on the driver side, so renaming it shouldn't cause
any compatibility issues with existing device trees.

Code for platform_device_create() and of_platform_device_destroy() is
only generated if CONFIG_OF_ADDRESS=y. Add stubs to avoid unresolved
symbols when CONFIG_OF_ADDRESS is not set.

Add function wake notification to support function remote wakeup,
currently assume the composite device only enable function wake
for the first interface.
Forward request to function driver when the recipient is an interface,
including:
GetStatus() request to the first interface in a function returns the
information about 'function remote wakeup' and 'function remote wakeup
capalbe';
SetFeature request of FUNCTION_SUSPEND to an interface recipient, the
controller driver saves the suspend option;

It is capable of supporting usb3 dual role if there is at least one
usb3 port for device and xhci controller, we can check it from the
controller's capability, so no need the property "mediatek,usb3-drd"
anymore, but I find the property is not decribed in dt-binding.
Meanwhile, also take into account if the u3 port is disabled when the
u3 phy is shared with pcie.

We may want to disable device's usb3 port when the combo phy is switched
from usb3 mode to pcie mode for some projects.
Meanwhile rename member @is_u3_ip to @u3_capable to avoid misleading, due
to the member's value may be changed when disable usb3 port, but the
controller is still a usb3 IP which also tells us how to manage the fifo.

USB PD controllers which consisting of a microcontroller (acting as the TCPM)
and a port controller (TCPC) - may require that the driver for the PD
controller accesses directly also the on-chip port controller in some cases.
Move tcpci.h to include/linux/usb/ is convenience access TCPC registers.

The driver won't probe on a LAN9668 because the pinctrl driver isn't
ready yet. Probe deferral is not supported because the init section
is already discarded. With fw_devlink enabled, the probe won't even
be called. Convert the driver to a proper platform driver.

The event classes udc_log_ep and udc_log_req both declare:
__dynamic_array(char, name, UDC_TRACE_STR_MAX)
Which will reserve UDC_TRACE_STR_MAX bytes on the ring buffer for the
event to write in name. It then uses snprintf() to write into that space.
Assuming that the string being copied is nul terminated, it is better to
just use the __string() helper. That way only the size of the string is
saved into the ring buffer and not the max size (yes, the entire
UDC_TRACE_STR_MAX is used in the trace event, and anything not used is
just junk in the ring buffer). Worse, there's also meta data saved into
the event that denotes where the string is stored in the event and also
saves its size, which is always going to be UDC_TRACE_STR_MAX.
Convert both to use the __string() and __assign_str() helpers that are for
this kind of use case.

Do not set pattrib's src, dst, bssid, ra and ta again in
sta2sta_data_frame.
sta2sta_data_frame is called from validate_recv_data_frame when both to_ds
and from_ds are 0. All pattrib address fields have already been set to the
correct addresses when sta2sta_data_frame is called.
memcpy(pattrib->dst, ieee80211_get_DA(hdr), ETH_ALEN);
ieee80211_get_DA returns addr1 if to_ds and from_ds are 0
memcpy(pattrib->src, ieee80211_get_SA(hdr), ETH_ALEN);
ieee80211_get_SA returns addr2 if to_ds and from_ds are 0
memcpy(pattrib->ra, hdr->addr1, ETH_ALEN);
memcpy(pattrib->ta, hdr->addr2, ETH_ALEN);
For pattrib->dst == addr1, pattrib->src == addr2, these
assignments match those in sta2sta_data_frame that this
patch removes.
