If we have any export symbols in nvmap, we would have to show the
interactions between KMDs as a path in our threat model.
Hence remove the following unnecessary export symbols from nvmap.
- nvmap_register_vidmem_carveout: Not being used on TOT
- nvmap_dev: Used by one of nvmap_ktest which is also being cleaned up.

Firmware requests triggered by userspace action can be executed
in interruptible context, which can cause signals to interrupt
firmware loading.
Ordinarily, one would propagate the error code to userspace and
let it retry. However, request_firmware does not have proper
handling of retryable errors, as sysfs fallbacks will clobber
the original error code. Furthermore, pm_runtime, through which
we would propagate the error code, doesn't support transient
resume failures either.
As such, as a quick fix, change to request_firmware_direct and
retry it directly in situ 10 times.

This patch fixes a race condition between
tegra_dce_unregister_ipc_client and dce_client_ipc_wakeup.
If dce_client_ipc_wakeup is called just after unregistering
it'll result in accessing already freed data structures and
kernel crash. This patch adds a check to validate if the client_ipc
struct is valid before accessing its members.

- Initialize lock per device node and take lock at the
start of processing of each ioctl command. This is needed
because there is only one set of IOVA buffers allocated
during init per device node. Without lock it leads to
race conditions when more than one app uses the same
device node.
- Release tfm after each API call for both sha and hmac-sha
- Validate rng buffer size provided by user
- Support buf size up to HW supported limit for GCM-Dec req

pci_client abstraction supports notification to application.
Each endpoint has to register with pci_client for notification which
return link_event_id after registration.
link_event_id is index in lookup table with total size as MAX_ENDPOINT.
This link_event_id is allocated sequential and does not match with ep_id
which is endpoint index with max as MAX_ENDPOINT.
stream-extension is not aware about link_event_id and uses ep_id for
notification which leads to mismatch in look up table finally dropping
notification.
Registering for link event in sequential manner does not help much as
registration against ep_id will make lookup table and endpoint database
one-to-one mapping.
Update endpoint registration for link event based on ep_id and use ep_id
in lookup table for notification purpose.
