Provide seccomp internals with the details to calculate which syscall
table the running kernel is expecting to deal with. This allows for
efficient architecture pinning and paves the way for constant-action

SECCOMP_CACHE_NR_ONLY will only operate on syscalls that do not
access any syscall arguments or instruction pointer. To facilitate
this we need a static analyser to know whether a filter will

The fast (common) path for seccomp should be that the filter permits
the syscall to pass through, and failing seccomp is expected to be
an exceptional case; it is not expected for userspace to call a
denylisted syscall over and over.
This first finds the current allow bitmask by

This patch set provides ACPI support to DPAA2 network drivers.
It also introduces new fwnode based APIs to support phylink and phy layers
Following functions are defined:
phylink_fwnode_phy_connect()
fwnode_mdiobus_register_phy()
fwnode_get_phy_id()
fwnode_phy_find_device()
device_phy_
Introduce ACPI mechanism to get PHYs registered on a MDIO bus and
provide them to be connected to MAC.
Describe properties "phy-handle" and "phy-mode".

Introduce fwnode_mdiobus_register_phy() to register PHYs on the
mdiobus. From the compatible string, identify whether the PHY is
c45 and based on this create a PHY device instance which is
registered on the mdiobus.

Modify dpaa2_mac_connect() to support ACPI along with DT.
Modify dpaa2_mac_get_node() to get the dpmac fwnode from either
DT or ACPI.
Replace of_get_phy_mode with fwnode_get_phy_mode to get
phy-mode for a dpmac_node.
Use helper function phylink_fwnode_phy_connect() to find phy_dev and
