We observed an interrupt storm on that interrupt
even after the usb path is suspended.
So keep this interrupt disabled as long as the usb
path is suspended.
Note that since the current limit votes can come in
prior to interrupt registration, rerun the election
on the votable after interrupts are registered.

Currently the buck frequency is set to 700kHz only when the smb138x is
in master mode. The buck frequency needs to be 700kHz in both master and
slave mode to prevent ADC errors. Do it.

Start offset is not considered in cache operation logic,
due to which bytes at the end of payload might be stale.
Add logic to add offset to cache operation length
from start of buffer, to ensure correct cache operation.

Pointer from userspace is de-referenced before the command is checked.
This might cause a crash if the command being sent is not a valid command.
Hence changing the de-reference such that the pointer is accessed after
checking if a valid command is sent from the userspace.

We have observed race condition between inquiring the remote pd state and
indication call back execution. They run asynchronously so we have no
control on their concurrent execution. So to achieve mutual exclusion,
moving the portion of code which result in race condition to indication
acknowledgment routine. Indication acknowledgment is send in separate
thread context which will avoid race condition.

__list_lru_walk_one() acquires nlru spin lock (nlru->lock) for longer
duration if there are more number of items in the lru list. As per the
current code, it can hold the spin lock for upto maximum UINT_MAX entries
at a time. So if there are more number of items in the lru list, then

Fix this lockup by reducing the number of entries to be shrinked from the

lru list again.

list_lru_count_node() iterates over all memcgs to get the total number of
entries on the node but it can race with memcg_drain_all_list_lrus(),
which migrates the entries from a dead cgroup to another. This can return
incorrect number of entries from list_lru_count_node().
Fix this by keeping track of entries per node and simply return it in
list_lru_count_node().
