sched_nr_migrate_break is set to a fix value and never changes so we can
replace it by a define SCHED_NR_MIGRATE_BREAK.
Also, we adjust SCHED_NR_MIGRATE_BREAK to be aligned with the init value
of sysctl_sched_nr_migrate which can be init to different values.
Then, use SCHED_NR_MIGRATE_BREAK to init sysctl_sched_nr_migrate.
The behavior stays unchanged unless you modify sysctl_sched_nr_migrate
trough debugfs.

During load balance, we try at most env->loop_max time to move a task.
But it can happen that the loop_max LRU tasks (ie tail of
the cfs_tasks list) can't be moved to dst_cpu because of affinity.
In this case, loop in the list until we found at least one.
The maximum of detached tasks remained the same as before.

Footbridge is the last Arm platform that has its own
__virt_to_bus()/__bus_to_virt()/phys_to_dma()/dma_to_phys() abstraction,
but this is just a simple offset now.
For PCI devices, the offset that is programmed into the PCI bridge must
also be set in each device using dma_direct_set_offset(). As Arm does
not have a pcibios_bus_add_device() helper yet, just use a bus notifier
for this.
For the ISA DMA, drivers now pass a non-translated physical address into
set_dma_addr(), so they have to be converted back with the corresponding
isa_bus_to_virt() function and then into the correct bus address with
the offset using the isa_dma_dev.

The RK3399 has a 1024-entry gamma LUT with 10 bits per component on its
"big" VOP and a 256-entry, 8 bit per component LUT on the "little" VOP.
Compared to the RK3288, it no longer requires disabling gamma while
updating the LUT. On the RK3399, the LUT can be updated at any time as
the hardware has two LUT buffers, one can be written while the other is
in use. A swap of the buffers is triggered by writing 1 to the
update_gamma_lut register.

The VOP on RK3399 has a different approach from previous versions for
setting a gamma lookup table, using an update_gamma_lut register. As
this differs from RK3288, give RK3399 its own set of "common" register

applied in suspend with HZ MCU timeout, especially it happened when we

Given that there's no data coming from network stack for binding flows,
hence driver counts and reports station's statistics directly through
NL80211_STA_INFO_* based on active PPDU based TxS for offloading data.
Apart from that, WA firmware and its offloading engine (SDO) have hardcoded
"2" as PID, so we introduce MT_PACKET_ID_WED to differentiate WED reporting.
Note that PPDU format TxS is mutually exclusive with MT_TXD5_TX_STATUS_HOST.
