When the suballocator was unable to provide a suitable buffer for the MMUv1
linear window, we roll back the GPU initialization. As the GPU is runtime
resumed at that point we need to clear the kernel cmdbuf suballoc entry to
properly skip any attempt to manipulate the cmdbuf when the GPU gets shut
down in the runtime suspend later on.

Use new return type vm_fault_t for fault handler. For
now, this is just documenting that the function returns
a VM_FAULT value rather than an errno. Once all instances
are converted, vm_fault_t will become a distinct type.
Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t")
Previously vm_insert_page() returns err which driver
mapped into VM_FAULT_* type. The new function
vmf_insert_page() will replace this inefficiency by
returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function
in 4.17-rc6.

The documentation of drm_sched_job_init and drm_sched_entity_push_job has

avoid jobs getting pushed into the scheduler queue in a different order

This GPIO controller can serve as an interrupt controller as well on the
GPIOs it handles.
An interrupt is generated whenever a GPIO line changes and the
interrupt for this GPIO line is enabled. This means that both the
changes from low to high and high to low generate an interrupt.
For some use cases, it makes sense to ignore the high to low change and
not generate an interrupt. Such a use case is a line that is hold in a
level high/low manner until the event holding the line gets acked.
This can be achieved by making sure the interrupt on the GPIO controller
side gets acked and masked only after the line gets hold in its default
state, this is what's done with the fasteoi functions.
Only IRQ_TYPE_EDGE_BOTH and IRQ_TYPE_LEVEL_HIGH are supported for now.

There isn't a hard dependency of the Xilinx AXI-PCIe host bridge on any
architecture. For example: at SiFive we map RISC-V cores to Xilinx FPGAs
and connect the Xilinx IP via a TileLink adapter, so the RISC-V Linux
port will need to be able to enable PCIE_XILINX in order to have PCIe
support.
This patch decouples the PCIE_XILINX support from ARCH. Instead it just
depends on OF, which is the only true dependency.

This patch adds a new virtual driver mac802154_hwsim which is based on
the fakelb driver.
The fakelb driver will get deprecated and hopefully removed someday.
The main reason for doing this step is to rename the driver to
mac802154_hwsim to have a similar naming scheme as mac80211_hwsim,
which is more popular in the 802.11 wireless word and the idea is the
same behind this driver.
The new features of this driver are to have knowledge about connected
edges, which can be changed during runtime. This offers a testing
environment for routing protocols e.g. RPL.
The default behaviour is still as fakelb: two radios connected to each
other. New added radios during runtime will not be connected to other
wpan_hwsim instances.
The netlink api is not namespace aware on purpose, only the registered
wpan_phy's can be moved to namespaces. The physical layer according to
wiresless "air" communication can be handled across namespaces.
Furthermore the edges can be weighted with the LQI value according IEEE
802.15.4 which offers additional handling to mark bad or good connection
indicators to other connected virtual phys.

not active, then any policy max frequency above turbo activation ratio
can result upto max one-core turbo frequency.

In order to give unicast traffic precedence over BUM traffic, configure
multicast-aware mode on all ports.
Under multicast-aware regime, when assigning traffic class to a packet,
the switch doesn't merely take the value prescribed by the QTCT
register. For BUM traffic, it instead assigns that value plus 8.
ETS elements for TCs 8..15 thus need to be configured as well. Extend
mlxsw_sp_port_ets_init() so that it maps each of them to the same
subgroup as their corresponding TC from the range 0..7, such that TCs X
and X+8 map to the same subgroup.
The existing code configures TCs with strict priority. So far this was
immaterial, because each TC had its own subgroup. Now that two TCs share
a subgroup it becomes important. TCs are prioritized in order of 7, 6,
..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being
deprioritized. Since that's what's needed, keep that configuration as it
is, and configure the new TCs likewise.
Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to
enable MC-aware mode on each port.
