Previous patches added various features that are needed for dynamic SHM.
Dynamic SHM allows Normal World to share any buffers with OP-TEE.
While original design suggested to use pre-allocated region (usually of
1M to 2M of size), this new approach allows to use all non-secure RAM for
command buffers, RPC allocations and TA parameters.
This patch checks capability OPTEE_SMC_SEC_CAP_DYNAMIC_SHM. If it was set
by OP-TEE, then kernel part of OP-TEE will use kernel page allocator
to allocate command buffers. Also it will set TEE_GEN_CAP_REG_MEM
capability to tell userspace that it supports shared memory registration.

With latest changes to OP-TEE we can use any buffers as a shared memory.
Thus, it is possible for supplicant to provide part of own memory
when OP-TEE asks to allocate a shared buffer.
This patch adds support for such feature into RPC handling code.
Now when OP-TEE asks supplicant to allocate shared buffer, supplicant
can use TEE_IOC_SHM_REGISTER to provide such buffer. RPC handler is
aware of this, so it will pass list of allocated pages to OP-TEE.

Now, when client applications can register own shared buffers in OP-TEE,
we need to extend ABI for parameter passing to/from OP-TEE.
So, if OP-TEE core detects that parameter belongs to registered shared

This change adds ops for shm_(un)register functions in tee interface.
Client application can use these functions to (un)register an own shared
buffer in OP-TEE address space. This allows zero copy data sharing between
Normal and Secure Worlds.
Please note that while those functions were added to optee code,
it does not report to userspace that those functions are available.
OP-TEE code does not set TEE_GEN_CAP_REG_MEM flag. This flag will be
enabled only after all other features of dynamic shared memory will be
implemented in subsequent patches. Of course user can ignore presence of
TEE_GEN_CAP_REG_MEM flag and try do call those functions. This is okay,
driver will register shared buffer in OP-TEE, but any attempts to use
this shared buffer will fail.

These functions will be used to pass information about shared
buffers to OP-TEE. ABI between Linux and OP-TEE is defined
in optee_msg.h and optee_smc.h.
optee_msg.h defines OPTEE_MSG_ATTR_NONCONTIG attribute
for shared memory references and describes how such references
should be passed. Note that it uses 64-bit page addresses even
on 32 bit systems. This is done to support LPAE and to unify
interface.

There were changes in REE<->OP-TEE ABI recently.
Now ABI allows us to pass non-contiguous memory buffers as list of

OPTEE_MSG_ATTR_NONCONTIG.
OP-TEE also is able to use all non-secure RAM for shared buffers. This

tcp: RACK loss recovery bug fixes
This patch set has four minor bug fixes in TCP RACK loss recovery.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
RACK skips an ACK unless it advances the most recently delivered
TX timestamp (rack.mstamp). Since RACK also uses the most recent
RTT to decide if a packet is lost, RACK should still run the
loss detection whenever the most recent RTT changes. For example,
an ACK that does not advance the timestamp but triggers the cwnd
undo due to reordering, would then use the most recent (higher)
RTT measurement to detect further losses.

When sender detects spurious retransmission, all packets
marked lost are remarked to be in-flight. However some may
be considered lost based on its timestamps in RACK. This patch
forces RACK to re-evaluate, which may be skipped previously if
the ACK does not advance RACK timestamp.

RACK does not test the loss recovery state correctly to compute
the reordering window. It assumes if lost_out is zero then TCP is
not in loss recovery. But it can be zero during recovery before
calling tcp_rack_detect_loss(): when an ACK acknowledges all
packets marked lost before receiving this ACK, but has not yet
to discover new ones by tcp_rack_detect_loss(). The fix is to
simply test the congestion state directly.

This happens because we increment rx_pkts on -ENOMEM and -EIO, resulting
in rx_pkts > 0. Fix this by only bumping rx_pkts if we were actually
given a non-zero budget.

The clock-names for pclk was wrongly set to "core", but the bindings
specifies "pclk".
This was not cathed until the legacy non-documented bindings were removed.

TCP BBR sampling fixes for loss recovery undo
This patch series has a few minor bug fixes for cases where spurious
loss recoveries can trick BBR estimators into estimating that the
available bandwidth is much lower than the true available bandwidth.
In both cases the fix here is to just reset the estimator upon loss
recovery undo.

Fix BBR so that upon notification of a loss recovery undo BBR resets
long-term bandwidth sampling.
Under high reordering, reordering events can be interpreted as loss.
If the reordering and spurious loss estimates are high enough, this
can cause BBR to spuriously estimate that we are seeing loss rates
high enough to trigger long-term bandwidth estimation. To avoid that
problem, this commit resets long-term bandwidth sampling on loss
recovery undo events.

Fix BBR so that upon notification of a loss recovery undo BBR resets
the full pipe detection (STARTUP exit) state machine.
Under high reordering, reordering events can be interpreted as loss.
If the reordering and spurious loss estimates are high enough, this
could previously cause BBR to spuriously estimate that the pipe is
full.
Since spurious loss recovery means that our overall sending will have
slowed down spuriously, this commit gives a flow more time to probe
robustly for bandwidth and decide the pipe is really full.
