The MEM_ACCEPT interface assumes that the Resource Manager (RM)
will always return an SG-List. This is not correct when the
caller provides an SG-List, in which case the RM will not return
an SG-List, as it doesn't need to, since the caller knows where
the memory has been mapped. Thus, if the caller specifies an SG-List,
and the MEM_ACCEPT call is successful, then simply return the SG-List
that they provided.

The __full_va_sweep() function within the functional fast DMA
test assumes that the first available mapping within the IOVA
space will be address 0. This was true when the IOVA allocation
code unconditionally set the starting search address to 0 when
it tried to wrap around to find an IOVA. However, since that is
no longer the case, change __full_va_sweep() to ensure that
the starting search address is 0 before executing the test.

These day, there are many platforms available in the embedded market
and they are smarter than kernel which has very limited information
about working set so they want to involve memory management more heavily
like android's lowmemory killer and ashmem or recent many lowmemory
notifier.
One of the simple imagine scenario about userspace's intelligence is that
platform can manage tasks as forground and background so it would be
better to reclaim background's task pages for end-user's *responsibility*
although it has frequent referenced pages.
This patch adds new knob "reclaim under proc/<pid>/" so task manager
can reclaim any target process anytime, anywhere. It could give another
method to platform for using memory efficiently.
It can avoid process killing for getting free memory, which was really
terrible experience because I lost my best score of game I had ever
after I switch the phone call while I enjoyed the game.
Reclaim file-backed pages only.
echo file > /proc/PID/reclaim
Reclaim anonymous pages only.
echo anon > /proc/PID/reclaim
Reclaim all pages
echo all > /proc/PID/reclaim

On some systems the firmware may not describe all the ports
connected to a component (e.g, for security reasons). This
could be especially problematic for "funnels" where we could
end up in modifying memory beyond the allocated space for

e.g, for a funnel with input ports listed 0, 3, 5, nr_inport = 3.
However the we could access refcnts[5] while checking for

To keep the code simple, we now track the maximum number of
possible input/output connections to/from this component
@ nr_inport and nr_outport in platform_data, respectively.
Thus the output connections could be sparse and code is
adjusted to skip the unspecified connections.

Currently, ucsi_qti_notify() is checking the received data from
charger firmware (PPM) to see if there is any connector status
response with partner accessory information (e.g. analog audio).
It does this based on setting a flag (cmd_requested_flags) when
UCSI_GET_CONNECTOR_STATUS command is sent from UCSI framework to
PPM so that the response for that command can be read and clients
registered for getting notification on partner accessory can get
notified. However, in a certain scenario, multiple response for
different commands can be received from PPM. See a possible
example below.
1. UCSI framework sends UCSI_GET_CONNECTOR_STATUS command
2. ucsi_glink driver sets cmd_requested_flags, waits for response
3. UCSI framework sends UCSI_GET_CURRENT_CAM command
4. ucsi_glink driver gets a response for UCSI_GET_CONNECTOR_STATUS
and schedules notify_work since ucsi_qti_notify() is called
with cmd_requested_flags set.
5. ucsi_glink driver gets a response for UCSI_GET_CURRENT_CAM and
this can end up reading "flags" because cmd_requested_flags is
not cleared yet. However, this causes a buffer overflow because
ucsi_qti_read() passes "val" pointer passed from UCSI framework
which is of 1 byte length and ucsi_qti_notify() ends up reading
"flags" which is at an offset 2 of length 9 bytes.
6. ucsi_qti_notify_work() clears cmd_requested_flags.
Fix this by checking the message length in ucsi_qti_notify()
to ensure that status->flags is read only when a response is
received for UCSI_GET_CONNECTOR_STATUS. Also, relocate the
clearing of "cmd_requested_flags" flag.
