In mark_chain_precision() logic, when we reach the entry to a global
func, it is expected that R1-R5 might be still requested to be marked
precise. This would correspond to some integer input arguments being
tracked as precise. This is all expected and handled as a special case.
What's not expected is that we'll leave backtrack_state structure with
some register bits set. This is because for subsequent precision
propagations backtrack_state is reused without clearing masks, as all
code paths are carefully written in a way to leave empty backtrack_state
with zeroed out masks, for speed.
The fix is trivial, we always clear register bit in the register mask, and
then, optionally, set reg->precise if register is SCALAR_VALUE type.

ionic: better Tx SG handling
The primary patch here is to be sure we're not hitting linearize on a Tx
skb when we don't really need to. The other two are related details.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When processing a TSO we may have frags spread across several
descriptors, and the total count of frags in one skb may exceed
our per descriptor IONIC_MAX_FRAGS: this is fine as long as
each descriptor has fewer frags than the limit. Since the skb
could have as many as MAX_SKB_FRAGS, and the first descriptor
is where we track and map the frag buffers, we need to be sure
we can map buffers for all of the frags plus the TSO header in
the first descriptor's buffer array.

Add a check of the queue's max_sg_elems against the maximum frags we

Signed-off-by: David S. Miller <davem@davemloft.net>
There are some cases where an skb carries more frags than the
number of SGs that ionic can support per descriptor - this
forces the driver to linearize the skb. However, if this
is a TSO packet that is going to become multiple descriptors
(one per MTU-sized packet) and spread the frags across them,
this time-consuming linearization is likely not necessary.
We scan the frag list and count up the number of SGs that
would be created for each descriptor that would be generated,
and only linearize if we hit the SG limit on a descriptor.
In most cases, we won't even get to the frag list scan, so
this doesn't affect typical traffic.

This series contains updates to ice driver only.
Sergey prepends ICE_ to PTP timer commands to clearly convey namespace

Karol adds retrying to acquire hardware semaphore for cross-timestamping
and avoids writing to timestamp registers on E822 devices. He also
renames some defines to be more clear and align with the data sheet.
Additionally, a range check is moved in order to reduce duplicated code.
Jake adds cross-timestamping support for E823 devices as well as adds
checks against netlist to aid in determining support for GNSS. He also
corrects improper pin assignment for certain E810-T devices and
refactors/cleanups PTP related code such as adding PHY model to ease checks
for different needed implementations, removing unneeded EXTTS flag, and

net: mdio: Convert to platform remove callback returning void
this series convert all platform drivers below drivers/net/mdio to
use remove_new. The motivation is to get rid of an integer return code
that is (mostly) ignored by the platform driver core and error prone on
the driver side.
See commit 5c5a7680e6 ("platform: Provide a remove callback that
returns no value") for an extended explanation and the eventual goal.
There are no interdependencies between the patches. As there are still
quite a few drivers to convert, I'm happy about every patch that makes
it in. So even if there is a merge conflict with one patch until you
apply, please apply the remainder of this series anyhow.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
