The RENESAS FemtoClock3 Wireless is a high-performance jitter attenuator,
frequency translator, and clock synthesizer. The device is comprised of 3
digital PLLs (DPLL) to track CLKIN inputs and three independent low phase
noise fractional output dividers (FOD) that output low phase noise clocks.
FemtoClock3 supports one Time Synchronization (Time Sync) channel to enable
an external processor to control the phase and frequency of the Time Sync
channel and to take phase measurements using the TDC. Intended applications
are synchronization using the precision time protocol (PTP) and
synchronization with 0.5 Hz and 1 Hz signals from GNSS.

This change is for the PHC devices that can measure the phase offset
between PHC signal and the external signal, such as the 1PPS signal of
GNSS. Reporting PTP_CLOCK_EXTOFF to user space will be piggy-backed to
the existing ptp_extts_event so that application such as ts2phc can
poll the external offset the same way as extts. Hence, ts2phc can use
the offset to achieve the alignment between PHC and the external signal
by the help of either SW or HW filters.

rx_data_reassembly skb is stored during NCI data exchange for processing
fragmented packets. It is dropped only when the last fragment is processed
or when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received.
However, the NCI device may be deallocated before that which leads to skb
leak.
As by design the rx_data_reassembly skb is bound to the NCI device and
nothing prevents the device to be freed before the skb is processed in
some way and cleaned, free it on the NCI device cleanup.

The MCA code can recover from an in-kernel #MC if the fixup type is
EX_TYPE_UACCESS, explicitly indicating that the kernel is attempting to
access userspace memory. However, if the fixup type is EX_TYPE_DEFAULT
the only thing that is raised for an in-kernel #MC is a panic.
ex_handler_uaccess() would warn if users gave a non-canonical addresses
(with bit 63 clear) to {get, put}_user(), which was unexpected.
Therefore, commit
b19b74bc99 ("x86/mm: Rework address range check in get_user() and put_user()")
replaced _ASM_EXTABLE_UA() with _ASM_EXTABLE() for {get, put}_user()
fixups. However, the new fixup type EX_TYPE_DEFAULT results in a panic.
Commit
6014bc2756 ("x86-64: make access_ok() independent of LAM")
added the check gp_fault_address_ok() right before the WARN_ONCE() in
ex_handler_uaccess() to not warn about non-canonical user addresses due
to LAM.
With that in place, revert back to _ASM_EXTABLE_UA() for {get,put}_user()
exception fixups in order to be able to handle in-kernel MCEs correctly
again.

AMD MI300 systems include on-die HBM3 memory and a unique topology. And
they fall under Data Fabric version 4.5 in overall design.
Generally, topology information (IDs, etc.) is gathered from Data Fabric
registers. However, the unique topology for MI300 means that some
topology information is fixed in hardware and follows arbitrary
mappings. Furthermore, not all hardware instances are software-visible,
so register accesses must be adjusted.
Recognize and add helper functions for the new MI300 interleave modes.
Add lookup tables for fixed values where appropriate. Adjust how Die and
Node IDs are found and used.
Also, fix some register bitmasks that were mislabeled.

filter to XFS_ATTR_INCOMPLETE. The filter is then reset in

The filter is not reset though if XFS just removes the attribute

Fix this by always resetting XFS_ATTR_INCOMPLETE filter. The replace

Mark of the Unicorn released 896 mk3 FireWire in 2008 as part of the third
generation of its FireWire series. In 2011, 896 mk3 hybrid was released to
support USB protocol.
It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in optical interfaces. The model supports
transmission of PCM frames as well as MIDI messages.
The 896 mk3 FireWire consists of below ICs:
* Texas Instruments TSB41AB2
* Xilinx Spartan-3A FPGA, XC3S500E
* Texas Instruments TMS320C6722
* Microchip (Atmel) AT91SAM SAM7S256
It supports sampling transfer frequency up to 192.0 kHz. The packet
format differs depending on both of current sampling transfer frequency
and the type of signal in two pairs of optical interfaces. The model
supports transmission of PCM frames, while has no port for MIDi messages.
The model supports command mechanism to configure internal DSP. Hardware
meter information is available in the first 2 chunks of each data block
of tx packet.
This commit adds support for it. The 896 mk3 FireWire is just tested, but
the 896 mk3 Hybrid is not yet.
