Memory region could  support at most 2 flush access flags:
IB_ACCESS_FLUSH_PERSISTENT and IB_ACCESS_FLUSH_GLOBAL

But we only allow user to register persistent flush flags to the pmem MR
where it has the ability of persisting data across power cycles.

So registering a persistent access flag to a non-pmem MR will be rejected.

This commit extends the RDMA kernel verbs ABI to support the flush
operation defined in IBA A19.4.1. These changes are
backward compatible with the existing RDMA kernel verbs ABI.

It makes device/HCA support new FLUSH attributes/capabilities, and it
also makes memory region support new FLUSH access flags.

Users can use ibv_reg_mr(3) to register flush access flags. Only the
access flags also supported by device's capabilities can be registered
successfully.

Once registered successfully, it means the MR is flushable. Similarly,
A flushable MR should also have one or both of GLOBAL_VISIBILITY and
PERSISTENT attributes/capabilities like device/HCA.

The code in rxe_resp.c at check_length() is incorrect as it compares
pkt->opcode an 8 bit value against various mask bits which are all higher
than 256 so nothing is ever reported.

This patch rewrites this to compare against pkt->mask which is
correct. However this now exposes another error. For UD send packets the
value of the pmtu cannot be determined from qp->mtu.  All that is required
here is to later check if the payload fits into the posted receive buffer
in that case.

After the hns roce driver is loaded, if you modify the mac address of the
network port, the following error will appear:

   __ib_cache_gid_add: unable to add gid fe80:0000:0000:0000:4600:4dff:fe22:abb5 error=-28
    hns3 0000:7d:00.0 hns_0: attr path_mtu(1) invalid while modify qp

The reason for the error is that the gid being occupied will cause the
failure to modify the gid. The gid is occupied by the loopback QP used by
free mr. When the mac address is modified, the gid will change. If there
is a busy QP at this time, the gid will not be released and the
modification will fail. The QP of free mr is created using the ib
interface. The ib interface will add a reference count to the gid,
resulting in this error scenario.

Considering that free mr is solving a bug in HIP08, not an actual
business, it is not necessary to use ib interfaces.

The ack timeout retransmission time is affected by the following two
factors: one is packet life time, another is the HCA processing time.

Now the default packet lifetime(CMA_IBOE_PACKET_LIFETIME) is 18.

That means the minimum ack timeout is 2
seconds (2^(18+1)*4us=2.097seconds).  The packet lifetime means the
maximum transmission time of packets on the network, 2 seconds is too
long.

Assume the network is a clos topology with three layers, every packet will
pass through five hops of switches. Assume the buffer of every switch is
128MB and the port transmission rate is 25 Gbit/s, the maximum
transmission time of the packet is 200ms(128MB*5/25Gbit/s).  Add double
redundancy, it is less than 500ms.

So change the CMA_IBOE_PACKET_LIFETIME to 16, the maximum transmission
time of the packet will be about 500+ms, it is long enough.

Currently tpm transactions are executed unconditionally in

accessors in the system.

Specifically, the hw_random tpm driver makes use of tpm_get_random(),

not frozen alongside userspace, and so can race with the work done
during system suspend:

The "force" argument to write_spec_ctrl_current() is currently ambiguous
as it does not guarantee the MSR write. This is due to the optimization
that writes to the MSR happen only when the new value differs from the
cached value.

This is fine in most cases, but breaks for S3 resume when the cached MSR
value gets out of sync with the hardware MSR value due to S3 resetting
it.

When x86_spec_ctrl_current is same as x86_spec_ctrl_base, the MSR write
is skipped. Which results in SPEC_CTRL mitigations not getting restored.

Move the MSR write from write_spec_ctrl_current() to a new function that
unconditionally writes to the MSR. Update the callers accordingly and
rename functions.
