by the watchdog.

Refactor watchdog core to remove dead code. Specifically,
the slack variables from the watchdog data structure and
the pet function that uses them. Currently these variables
are not used and can be refactored to simply reset the
watchdog counter directly.

In preparation to change the qcom watchdog to a new core
framework that future watchdog drivers will utilize, the name
of the file needs to be changed. Due to the number of changes
needed in the file we need to rename it to reflect its new purpose.

Set the bhi and bhie pointers to NULL as part of clean
up. This makes sure that stale pointers are not accessed
in case the bhi or bhie is failed to initialize during
power up.

Enable RCU NOCB_CPU and FAST_NO_HZ options for the lahaina. These configs
are needed to avoid frequent cpu wake up for processing rcu callbacks.
Whenever LPM governor driver has requested for sleep length
tick_nohz_get_sleep_length tries to find the next event from
tick_nohz_next_event function.
static ktime_t tick_nohz_next_event(struct tick_sched *ts, int cpu)
{
...
if (rcu_needs_cpu(basemono, &next_rcu) || arch_needs_cpu() ||
irq_work_needs_cpu() || local_timer_softirq_pending()) {
next_tick = basemono + TICK_NSEC;
} else {
tick_nohz_next_event calls rcu_needs_cpu to find whether future
non-offloaded RCU-related work need to be done by the current CPU
or not. If any non-offloaded future callbacks are present rcu
framework requests the cpu to wake up for every tick period to
process the callbacks.
When CONFIG_FAST_NO_HZ is defined rcu_needs_cpu function checks whether
any callbacks are ready to process or not. If there are no ready
call backs and no non-offloaded callbacks pending for this CPU, RCU
doesn't need the CPU and returns KTIME_MAX for sleep length. Another
important thing is that, if CPU has lazy callbacks or future non-offload
RCU callbacks, rcu framework try to advance those callbacks and allows
the CPU to enter dyntick-idle mode.
RCU_NOCB_CPU config option helps to offload callback invocation from
the set of CPUs to kthread ("rcuox/N") and reduce OS jitter for
aggressive high performance computing workloads.

The thermal zone ops pointer is allocated and initialized during
building thermal zone at early boot. The framework expects this
variable is valid as long as that thermal zone exist. Later if
a sensor is registered to thermal zone and then unregistered the
same due to some reason, it resets this thermal zone ops variable.
It leads to unexpected behaviour whenever thermal framework tries
to use it.
Don't reset thermal zone ops variable during of-thermal sensor
unregister context.

Once command completion times out (5 sec), command
abort operation is currently perfomed with local irq
disabled and spinlock held for 5 sec timeout. In case
xHC becomes unresponsive for some reason this results
into watchdog bark. Hence reduce timeout value from 5
sec to 1 sec to initiate recovery faster.

In kgsl_ioctl_gpuobj_import(), user memory of type KGSL_USER_MEM_TYPE_ADDR
can also lead to setting up a dma buffer. When attaching mem entry to
process fails, dma buffer attachment is cleaned up only in case of
KGSL_USER_MEM_TYPE_DMABUF. Similar situation can arise in case of
kgsl_ioctl_map_user_mem(). Fix this by obtaining user memory type from
the memdesc flags.
