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().

Fence lock is not taken in sync_print_fence() while calling
sync_print_pt() which in turn calls fence_is_signaled() to check the
status of each fence before printing. This creates a race condition
that corrupts fence data structure when another thread calls
fence_is_signaled_locked() on the same fence. Since we don't need to
signal the fence while logging, it can be fixed by simply checking fence
flag status directly instead of calling fence_is_signaled_locked().

While switching from hs400 to hs200 mode, high speed mode
timing should be selected in the device before changing the
clock frequency in the host. But current implementation,
(mmc_hs400_to_hs200) first updates the frequency in the host
and then updates mode in the device. This is a spec violation.
Hence update the sequence to comply with the spec.
