Pull libnvdimm fixes from Dan Williams:
"Two regression fixes, two bug fixes for older issues, two fixes for
new functionality added this cycle that have userspace ABI concerns,
and a small cleanup. These have appeared in a linux-next release and
have a build success report from the 0day robot.
* The 4.16 rework of altmap handling led to some configurations
leaking page table allocations due to freeing from the altmap
reservation rather than the page allocator.
The impact without the fix is leaked memory and a WARN() message
when tearing down libnvdimm namespaces. The rework also missed a
place where error handling code needed to be removed that can lead
to a crash if devm_memremap_pages() fails.
* acpi_map_pxm_to_node() had a latent bug whereby it could
misidentify the closest online node to a given proximity domain.
* Block integrity handling was reworked several kernels back to allow
calling add_disk() after setting up the integrity profile.
The nd_btt and nd_blk drivers are just now catching up to fix
automatic partition detection at driver load time.
* The new peristence_domain attribute, a platform indicator of
whether cpu caches are powerfail protected for example, is meant to
be a single value enum and not a set of flags.
This oversight was caught while reviewing new userspace code in
libndctl to communicate the attribute.
Fix this new enabling up so that we are not stuck with an unwanted
userspace ABI"

We already detect situations where a PPP channel sends packets back to
its upper PPP device. While this is enough to avoid deadlocking on xmit
locks, this doesn't prevent packets from looping between the channel
and the unit.
The problem is that ppp_start_xmit() enqueues packets in ppp->file.xq
before checking for xmit recursion. Therefore, __ppp_xmit_process()
might dequeue a packet from ppp->file.xq and send it on the channel
which, in turn, loops it back on the unit. Then ppp_start_xmit()
queues the packet back to ppp->file.xq and __ppp_xmit_process() picks
it up and sends it again through the channel. Therefore, the packet
will loop between __ppp_xmit_process() and ppp_start_xmit() until some
other part of the xmit path drops it.
For L2TP, we rapidly fill the skb's headroom and pppol2tp_xmit() drops
the packet after a few iterations. But PPTP reallocates the headroom
if necessary, letting the loop run and exhaust the machine resources
(as reported in https://bugzilla.kernel.org/show_bug.cgi?id=199109).
Fix this by letting __ppp_xmit_process() enqueue the skb to
ppp->file.xq, so that we can check for recursion before adding it to
the queue. Now ppp_xmit_process() can drop the packet when recursion is
detected.
__ppp_channel_push() is a bit special. It calls __ppp_xmit_process()
without having any actual packet to send. This is used by
ppp_output_wakeup() to re-enable transmission on the parent unit (for
implementations like ppp_async.c, where the .start_xmit() function
might not consume the skb, leaving it in ppp->xmit_pending and
disabling transmission).
Therefore, __ppp_xmit_process() needs to handle the case where skb is
NULL, dequeuing as many packets as possible from ppp->file.xq.

When the IRQ handler determines that one of the cmd IO channels has
failed and schedules recovery, block any further cmd requests from
being submitted. The request would inevitably stall, and prevent the
recovery from making progress until the request times out.
This sort of error was observed after Live Guest Relocation, where
the pending IO on the READ channel intentionally gets terminated to
kick-start recovery. Simultaneously the guest executed SIOCETHTOOL,
triggering qeth to issue a QUERY CARD INFO command. The command
then stalled in the inoperabel WRITE channel.

On removal, a qeth card's netdevice is currently not properly freed
because the call chain looks as follows:
qeth_core_remove_device(card)
lx_remove_device(card)
unregister_netdev(card->dev)
card->dev = NULL !!!
qeth_core_free_card(card)
if (card->dev) !!!
free_netdev(card->dev)
Fix it by free'ing the netdev straight after unregistering. This also
fixes the sysfs-driven layer switch case (qeth_dev_layer2_store()),
where the need to free the current netdevice was not considered at all.
Note that free_netdev() takes care of the netif_napi_del() for us too.

EEE is supported by this phy device. And the subsequent writing to

The bitfield dma_inuse is allocated of size dma_requests bits, thus a
valid bit address is from 0 to (dma_requests - 1).
When find_first_zero_bit() fails, it returns dma_requests as invalid
address.
Using such address for the following set_bit() is incorrect and, if
dma_requests is a multiple of BITS_PER_LONG, it will cause a buffer
overflow.
Currently this driver is only used in DT stm32h743.dtsi where a safe value
dma_requests=16 is not triggering the buffer overflow.
Fixed by checking the return value of find_first_zero_bit() _before_
using it.

The persistence domain is a point in the platform where once writes
reach that destination the platform claims it will make them persistent
relative to power loss. In the ACPI NFIT this is currently communicated
as 2 bits in the "NFIT - Platform Capabilities Structure". The bits
comprise a hierarchy, i.e. bit0 "CPU Cache Flush to NVDIMM Durability on
Power Loss Capable" implies bit1 "Memory Controller Flush to NVDIMM
Durability on Power Loss Capable".
Commit 96c3a23905 "libnvdimm: expose platform persistence attr..."
shows the persistence domain as flags, but it's really an enumerated
hierarchy.
Fix this newly introduced user ABI to show the closest available
persistence domain before userspace develops dependencies on seeing, or
needing to develop code to tolerate, the raw NFIT flags communicated
