We were erroneously checking the length of the tlv instead of checking
the pointer returned by kmemdup() when allocating dbg_conf_tlv[].
This was probably a typo. Fix it by checking the returned pointer
instead of the length.

The AP may set the LDPC capability only in HE (IEEE80211_HE_PHY_CAP1),
but we were checking it only in the HT capabilities.
If we don't use this capability when required, the DSP gets the wrong
configuration in HE and doesn't work properly.

generic scheduler code
drivers/base/arch_topology.c is only built if CONFIG_GENERIC_ARCH_TOPOLOGY=y,
resulting in such build failures:
cpufreq_cooling.c:(.text+0x1e7): undefined reference to `arch_set_thermal_pressure'
Move it to sched/core.c instead, and keep it enabled on x86 despite
us not having a arch_scale_thermal_pressure() facility there, to
build-test this thing.

Since commit 3bc3206e1c0f ("serial: fsl_lpuart: Remove the alias node
dependence") the port line number can also be allocated by IDA, but in
case of an error the ID will no be removed again. More importantly, any
ID will be freed in remove(), even if it wasn't allocated but instead
fetched by of_alias_get_id(). If it was not allocated by IDA there will
be a warning:
WARN(1, "ida_free called for id=%d which is not allocated.\n", id);
Move the ID allocation more to the end of the probe() so that we still
can use plain return in the first error cases.

This reverts commit a659652f6169240a5818cb244b280c5a362ef5a4.
This broke the earlycon on LS1021A processors because the order of the
earlycon_setup() functions were changed. Before the commit the normal
lpuart32_early_console_setup() was called. After the commit the
lpuart32_imx_early_console_setup() is called instead.

On Apple devices the _CRS method returns an empty resource template, and
the resource settings are instead provided by the _DSM method. But
commit 33364d63c75d6182fa369cea80315cf1bb0ee38e (serdev: Add ACPI
devices by ResourceSource field) changed the search for serdev devices
to require valid, non-empty resource template, thereby breaking Apple
devices and causing bluetooth devices to not be found.
This expands the check so that if we don't find a valid template, and
we're on an Apple machine, then just check for the device being an
immediate child of the controller and having a "baud" property.

The peripheral has support for inverting its input and/or output
signals. This is useful if the hardware flips polarity of the
peripheral's signal, such as swapped +/- pins on an RS-422 transceiver,
or an inverting level shifter. Add support for these control registers
via the device tree binding.
As part of this change, make the writes of the various registers more
uniform by moving the UCR3 block up near the other registers' blocks,
since the INVT bit must be set before enabling the peripheral.

capping
Thermal governors can request for a CPU's maximum supported frequency to
be capped in case of an overheat event. This in turn means that the
maximum capacity available for tasks to run on the particular CPU is
reduced. Delta between the original maximum capacity and capped maximum
capacity is known as thermal pressure. Enable cpufreq cooling device to
update the thermal pressure in event of a capped maximum frequency.

instantaneous thermal pressure
Add architecture specific APIs to update and track thermal pressure on a
per CPU basis. A per CPU variable thermal_pressure is introduced to keep
track of instantaneous per CPU thermal pressure. Thermal pressure is the
delta between maximum capacity and capped capacity due to a thermal event.
topology_get_thermal_pressure can be hooked into the scheduler specified
arch_scale_thermal_pressure to retrieve instantaneous thermal pressure of
a CPU.
arch_set_thermal_pressure can be used to update the thermal pressure.
Considering topology_get_thermal_pressure reads thermal_pressure and
arch_set_thermal_pressure writes into thermal_pressure, one can argue for
some sort of locking mechanism to avoid a stale value. But considering
topology_get_thermal_pressure can be called from a system critical path
like scheduler tick function, a locking mechanism is not ideal. This means
that it is possible the thermal_pressure value used to calculate average
thermal pressure for a CPU can be stale for up to 1 tick period.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
The original code used a simple for-loop to read the bytes in order into
a buffer one byte at a time.
The pci_get_dsn() function returns the DSN as a u64, correctly ordering
the upper and lower 32 bit dwords. Simplify the display code by using
%016llX to display the u64 DSN.
This should have equivalent behavior on both Little and Big Endian
systems. The bus will have correctly ordered the dwords in the CPU
endian format, while pci_get_dsn() will correctly order the lower and
higher dwords into a u64.

The original code used a for-loop that looped over each of the 8 bytes
and copied them into a temporary buffer. pci_get_dsn() uses two calls to

we can simplify the snprintf significantly using %016llX on a u64 value.

Replace the open-coded implementation for reading the PCIe DSN with
pci_get_dsn().
Use of put_unaligned_le64 should be correct. pci_get_dsn() will perform
two pci_read_config_dword calls. The first dword will be placed in the
first 32 bits of the u64, while the second dword will be placed in the
upper 32 bits of the u64.
On Little Endian systems, the least significant byte comes first, which
will be the least significant byte of the first dword, followed by the
least significant byte of the second dword. Since the _le32 variations
do not perform byte swapping, we will correctly copy the dwords into the
dsn[] array in the same order as before.
On Big Endian systems, the most significant byte of the second dword
will come first. put_unaligned_le64 will perform a CPU_TO_LE64, which
will swap things correctly before copying. This should also end up with
the correct bytes in the dsn[] array.
While at it, fix a small typo in the netdev_info error message when the
DSN cannot be read.

The emulated vbt doesn't tell its size correctly. According to the
intel_vbt_defs.h, vbt_header.vbt_size should the size of VBT (VBT Header,
BDB Header and data blocks), and bdb_header.bdb_size should be the size
of BDB (BDB Header and data blocks).
This patch fixes the issue and lets vbt provided by GVT-g pass the guest
i915's sanity test.
v2: refine the commit message. (Zhenyu)

When local NET_RX backlog is full due to traffic overrun,
peer veth tx_dropped counter increases. At that time, list
local veth stats, rx_dropped has double value of peer
tx_dropped, even bigger than transmit packets by peer.
In NET_RX softirq process, if any packet drop case happens,
it increases dev's rx_dropped counter and returns NET_RX_DROP.
At veth tx side, it records any error returned from peer netif_rx
into local dev tx_dropped counter.
In veth get stats process, it puts local dev rx_dropped and
peer dev tx_dropped into together as local rx_drpped value.
So that it shows double value of real dropped packets number in
this case.
This patch ignores peer tx_dropped when counting local rx_dropped,
since peer tx_dropped is duplicated to local rx_dropped at most cases.

Since in the software implementation of XTS-AES there is
no notion of sector every input length is processed the same way.
CAAM implementation has the notion of sector which causes different
results between the software implementation and the one in CAAM
for input lengths bigger than 512 bytes.
Increase sector size to maximum value on 16 bits.

HW generates a Data Size error for chacha20 requests that are not
a multiple of 64B, since algorithm state (AS) does not have
the FINAL bit set.
Since updating req->iv (for chaining) is not required,
modify skcipher descriptors to set the FINAL bit for chacha20.
[Note that for skcipher decryption we know that ctx1_iv_off is 0,
which allows for an optimization by not checking algorithm type,
since append_dec_op1() sets FINAL bit for all algorithms except AES.]
Also drop the descriptor operations that save the IV.
However, in order to keep code logic simple, things like
S/G tables generation etc. are not touched.

When uacce parent device module is removed, user app may
still keep the mmaped area, which can be accessed unsafely.
When rmmod, Parent device driver will call uacce_remove,
which unmap all remaining mapping from user space for safety.
VM_FAULT_SIGBUS is also reported to user space accordingly.

The incorrect traversal of the scatterlist, during the linearization phase
lead to computing the hash value of the wrong input buffer.
New implementation uses scatterwalk_map_and_copy()
to address this issue.
