Also with this one, it is a cast that always occurred
and is just being done explicitly, with no changes to
the generated code.
The warning stack is misleading, it points to the last
element in the macro that produced the lhs of the subtraction
above. But the only "unsigned long int" in the expression is
the result of the sizeof() on the rhs, it promotes the
subtraction result to unsigned long. So the error actually
relates to the result of the outer subtraction.
The actual error is "you are trying to put an unsigned long
into a uint32_t". We always did so, the fix is just to inform
the compiler it is intentional with an explicit cast.

it has always been implicitly cast to uint32_t when it
is used in the arguments to rte_atomic32_cmpset()...

Running testpmd command "flow isolae <port> 0" (i.e. disabling flow
isolation) followed by command "flow isolate <port> 1" (i.e. enabling
flow isolation) may result in a TAP error:
PMD: Kernel refused TC filter rule creation (17): File exists
Root cause analysis: when disabling flow isolation we keep the local
rule to redirect packets on TX (TAP_REMOTE_TX index) while we add it
again when enabling flow isolation. As a result this rule is added
two times in a row which results in "File exists" error.
The fix is to identify the "File exists" error and silently ignore it.
Another issue occurs when enabling isolation mode several times in a
row in which case the same tc rules are added consecutively and
rte_flow structs are added to a linked list before removing the
previous rte_flow structs.
The fix is to act upon isolation mode command only when there is a
change from "0" to "1" (or vice versa).

This patch caches all dirty pages logging until the used ring index

The goal of this optimization is to fix a performance regression
introduced when the vhost library started to use atomic operations
to set bits in the shared dirty log map. While the fix was valid
as previous implementation wasn't safe against concurrent accesses,
contention was induced.
With this patch, during migration, we have:
1. Less atomic operations as only a single atomic OR operation
per 32 or 64 (depending on CPU) pages.
2. Less atomic operations as during a burst, the same page will
be marked dirty only once.
3. Less write memory barriers.

Fix it by removing the check in populate virt. populate_anon() function

bus/dpaa: fix inconsistent struct alignment
The actual descriptor for qm_mr_entry is 64-byte aligned.
But the original code plays a trick, and puts a u8 common
to the three descriptor subtypes in the union afterwards
outside their structure definitions.
Unfortunately since they compose a struct qm_fd with
alignment 8, this trick destroys the ability of the compiler
to understand what has happened, resulting in this kind of
problem:
drivers/bus/dpaa/include/fsl_qman.h:354:3: error:
alignment 1 of ‘struct <anonymous>’ is less than 8 [-Werror=packed-not-aligned]
} __packed dcern;
on gcc 8 / Fedora 28 out of the box.
This patch moves the u8 verb into the structure definitions
composed into the union, so the alignment of the parent struct
containing the alignment 8 object can also be seen to be
alignment 8 by the compiler. Uses of .verb are fixed up to use
.ern.verb (the same offset of +0 inside all the structs in
the union).
The final struct layout should be unchanged.

net/bonding: fix slave activation simultaneously
The bonding PMD decides to activate\deactivate its slaves according to
the slaves link statuses.
Thus, it registers to the LSC events of the slaves ports and
activates\deactivates them from its LSC callbacks called asynchronously
by the host thread when the slave link status is changed.
In addition, the bonding PMD uses the callback for slave activation
when it tries to start it, this operation is probably called by the
master thread.
Consequently, a slave may be activated in the same time by two
different threads and may cause a lot of optional errors, for example,
slave mempool recreation with the same name causes an error.
Synchronize the critical section in the LSC callback using a special
new spinlock.

Move freeing up resources from dev_close() to dev_uninit(). This fixes
NULL pointer de-reference when accessing adapter context needed by
other ports under same PF, but had been freed up by the first port.
This can happen if only the first port is started up and the check
to free up all resources is still satisfied. When dev_close is
called for other ports, adapter context is NULL since it was freed
up by the first port.
Thus, by moving to dev_uninit() all the ports can be teared down
safely without need for extra checks.
