In some cases, its possible that most of a VM's memory is not
accessible to virtual io backend drivers that run in the context of a
separate VM. A hypervisor could pre-share some limited memory between
both the VMs. Use such pre-arranged shared memory to allow data
exchange between front-end and back-end drivers. DMA ops are added to
virtual io (mmio) devices, which bounces buffers to and from the
pre-shared region.

If LMH (Limits Management Hardware) is available, when a policy is
disabled by unplugging the last online CPU of policy->cpus, the LMH
irq is left enabled.
When the policy is re-enabled with any of the CPU in policy->cpus
being plugged in, qcom_cpufreq_ready() re-enables the irq. This
triggers the following warning:
[ 379.160106] Unbalanced enable for IRQ 154
[ 379.160120] WARNING: CPU: 7 PID: 48 at kernel/irq/manage.c:774 __enable_irq+0x84/0xc0

When cpu is hotplugged out, cpu stack is torn down and lmh mitigation
also stops. Hence on lmh exit remove thermal pressure.
This will ensure that scheduler requests higher frequency when
cpu is back online again, since it's likely the CPU has cooled down
in the meantime. And if it hasn't, then lmh IRQ will fire again and
we'll reapply pressure.

If LMH (Limits Management Hardware) is available, when a policy is
disabled by unplugging the last online CPU of policy->cpus,
qcom_cpufreq_hw_cpu_offline() sets cancel_throttle=true.
cancel_throttle is not reset when the policy is re-enabled with any
of the CPU in policy->cpus being plugged in. So reset it.
This patch also adds an early exit check.

If cpu is hotplugged then policy->cpus is cleared in cpufreq_offline
which will results in device being NULL on last CPU hotplugged out.
Also since cpu is hotplugged out, polling callback can safely be
ignored in this case.

Currently, when lmh interrupt fires we notify the scheduler about
thermal pressure. The scheduler reduces the capacity of the cpu(s)
for which the interrupt fired, while we requeue our deferrable work.
This leads to an interesting deadlock, since the cpu is running with
reduced capacity, the scheduler does not put any task on it,
extending the idle time and causing it to remain at reduced capacity -
leading to severe underutilization of the cpu(s).
Switch to using delayed work instead of deferrable work. This will cause
us to exit idle until the thermal condition is recovered.

driver_data is freed between cpu_freq framework cpufreq_offline
and cpufreq_online callbacks. cycle counter api can be invoked by
irq inbetween cpu online/init call which can lead to panic if
driver_date is released on last exit callback from framework.
Hence for now keep driver_data, once allocated in init call.
