There was a divergence between Linux and ACPICA on the definition of
ACPI_DEBUG_DEFAULT. This divergence was solved by taking ACPICA's
definition in 4c1379d7bb. After resolving the divergence, it was
clear that Linux users wanted to use their old set of debug flags.
This change fixes the divergence by setting these debug flags during
acpi_early_init() rather than during global variable initialization
in acpixf.h (owned by ACPICA).

To fix it, add route_dev in mlx5e_encap_entry struct to save

flush all the neighbour on the netdevice and send NETEVENT_NEIGH_UPDATE

There are at least four different parts with the same Vendor and Device
ID ([16c3:abcd]):
1) Synopsys HAPS USB3 controller
2) Synopsys PCIe Root Port in Freescale/NXP i.MX6Q (reported by Lucas)
3) Synopsys PCIe Root Port in Freescale/NXP i.MX6QP (reported by Lukas)
4) Synopsys PCIe Root Port in Freescale/NXP i.MX7D (reported by Trent)
The HAPS USB3 controller has a Class Code of PCI_CLASS_SERIAL_USB_XHCI,
which means the XHCI driver would normally claim it. Previously,
quirk_synopsys_haps() changed the Class Code of all [16c3:abcd] devices,
including the Root Ports, to PCI_CLASS_SERIAL_USB_DEVICE to prevent the
XHCI driver from claiming them so dwc3-haps can claim them instead.
Changing the Class Code of the Root Ports prevents the PCI core from
handling them as bridges, so devices below them don't work.
Restrict the quirk so it only changes the Class Code for devices that start
with the PCI_CLASS_SERIAL_USB_XHCI Class Code, leaving the Root Ports
alone.

bio_trim() has an early return, which makes it _not_ idempotent, if the
offset is 0 and the bio's bi_size already matches the requested size.
Prior to DM, all users of bio_trim() were fine with this. But DM has
exposed the fact that bio_trim()'s early return is incompatible with a
cloned bio whose integrity payload must be trimmed via
bio_integrity_trim().
Fix this by reverting DM back to doing the equivalent of bio_trim() but
in an idempotent manner (so bio_integrity_trim is always performed).
Follow-on work is needed to assess what benefit bio_trim()'s early
return is providing to its existing callers.

Block core changes to switch bio-based IO accounting to be percpu had a
side-effect of altering DM core to now rely on calling waitqueue_active
(in both bio-based and request-based) to check if another task is in
dm_wait_for_completion().
A memory barrier is needed before calling waitqueue_active(). DM core
doesn't piggyback on a preceding memory barrier so it must explicitly
use its own.
For more details on why using waitqueue_active() without a preceding
barrier is unsafe, please see the comment before the waitqueue_active()
definition in include/linux/wait.h.
Add the missing memory barrier by switching to using wq_has_sleeper().

Two and a half years ago, the client was changed to use gathered
Send for larger inline messages, in commit 655fec6987 ("xprtrdma:
Use gathered Send for large inline messages"). Several fixes were
required because there are a few in-kernel device drivers whose
max_sge is 3, and these were broken by the change.
Apparently my memory is going, because some time later, I submitted
commit 25fd86eca1 ("svcrdma: Don't overrun the SGE array in
svc_rdma_send_ctxt"), and after that, commit f3c1fd0ee2 ("svcrdma:
Reduce max_send_sges"). These too incorrectly assumed in-kernel
device drivers would have more than a few Send SGEs available.
The fix for the server side is not the same. This is because the
fundamental problem on the server is that, whether or not the client
has provisioned a chunk for the RPC reply, the server must squeeze
even the most complex RPC replies into a single RDMA Send. Failing
in the send path because of Send SGE exhaustion should never be an
option.
Therefore, instead of failing when the send path runs out of SGEs,
switch to using a bounce buffer mechanism to handle RPC replies that
are too complex for the device to send directly. That allows us to
remove the max_sge check to enable drivers with small max_sge to
work again.
