In this commit, we dump the monitor attributes when queried.
The link monitor attributes are separated into two kinds:
1. general attributes per bearer
2. specific attributes per node/peer
This style resembles the socket attributes and the nametable
publications per socket.

NUD_STALE is used when the caller(e.g. arp_process()) can't guarantee
neighbour reachability. If the entry was NUD_VALID and lladdr is unchanged,
the entry state should not be changed.
Currently the code puts an extra "NUD_CONNECTED" condition. So if old state
was NUD_DELAY or NUD_PROBE (they are NUD_VALID but not NUD_CONNECTED), the
state can be changed to NUD_STALE.
This may cause problem. Because NUD_STALE lladdr doesn't guarantee
reachability, when we send traffic, the state will be changed to
NUD_DELAY. In normal case, if we get no confirmation (by dst_confirm()),
we will change the state to NUD_PROBE and send probe traffic. But now the
state may be reset to NUD_STALE again(e.g. by broadcast ARP packets),
so the probe traffic will not be sent. This situation may happen again and
again, and packets will be sent to an non-reachable lladdr forever.
The fix is to remove the "NUD_CONNECTED" condition. After that the
"NEIGH_UPDATE_F_WEAK_OVERRIDE" condition (used by IPv6) in that branch will
be redundant, so remove it.
This change may increase probe traffic, but it's essential since NUD_STALE
lladdr is unreliable. To ensure correctness, we prefer to resolve lladdr,
when we can't get confirmation, even while remote packets try to set
NUD_STALE state.

Builddep is not very explicit about file permissions. Actually the file
permissions in the package are largely influenced by the umask of the
user cloning the git and building the package. If that umask does not
set go+r the resulting linux-headers package will prevent non-root users
from building out-of-tree modules. And that is probably just one
unexpected effect.
Being a packaging/install tool builddep should make sure the file
permissions are set correctly and not just derived from a value that is
never checked.
This patch sets ugo read permissions for all packaged files and derives
the executable bit for directories and executables from the file-owner.

The value that should be programmed into the PADS_REFCLK register varies
per SoC. Fix the Tegra PCIe driver to program the correct values. Future
SoCs will require different values in cfg0/1, so the two values are stored
separately in the per-SoC data structures.
For reference, the values are all documented in NV bug 1771116 comment 20.
The ASIC team has validated all these values, except for the Tegra20 value
which is simply left unchanged in this patch.

At present, when creating module's map, perf gets 'start' address by
parsing '/proc/modules', but it's the module base address, it isn't the
start address of the '.text' section.
In most arches, it's OK. But for s390, it places 'GOT' and 'PLT'
relocations before '.text' section. So there exists an offset between
module base address and '.text' section, which will incur wrong symbol
resolution for modules.
Fix this bug by getting 'start' address of module's map from parsing
'/sys/module/[module name]/sections/.text', not from '/proc/modules'.

Pull s390 updates from Martin Schwidefsky:
"There are a couple of new things for s390 with this merge request:
- a new scheduling domain "drawer" is added to reflect the unusual
topology found on z13 machines. Performance tests showed up to 8
percent gain with the additional domain.
- the new crc-32 checksum crypto module uses the vector-galois-field
multiply and sum SIMD instruction to speed up crc-32 and crc-32c.
- proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in
the generic vmlinux.lds linker script definitions.
- kcov instrumentation support. A prerequisite for that is the
inline assembly basic block cleanup, which is the reason for the
net/iucv/iucv.c change.
- support for 2GB pages is added to the hugetlbfs backend.
Then there are two removals:
- the oprofile hardware sampling support is dead code and is removed.
The oprofile user space uses the perf interface nowadays.
- the ETR clock synchronization is removed, this has been superseeded
be the STP clock synchronization. And it always has been
"interesting" code..

This patch makes the symbol "tristate", which lets the Kconfig
dependency tracking handle it correctly. To make the module
actually usable, I also revert 0af61e66ee ("drivers/staging:
make emxx_udc.c explicitly non-modular"), which Paul Gortmaker
added after noticing that the Kconfig symbol was 'bool'.
Compared to the original version however, I leave out the
'__exit' annotation on the remove callback, as Paul pointed
out that this was incorrect.

Since 0b52297f22 ("reset: Add support for shared reset controls") the
new Reset API now demands consumers choose either an *_exclusive or a
*_shared line when requesting reset lines.
This issue was found when running a kernel containing the aforementioned
patch which includes an informitive WARN(). It implies that one or
more used reset lines are in fact shared. This is why we're using the
*_shared variant.

A two-level page-table can map up to 1GB of address space.
With the IOVA allocator now in use, the allocated addresses
are often more closely to 4G, which requires the address
space to be increased much more often. Avoid that by using a
three-level page-table by default.

Not doing so might cause IO-Page-Faults when a device uses
an alias request-id and the alias-dte is left in a lower
page-mode which does not cover the address allocated from
the iova-allocator.

__btrfs_abort_transaction doesn't use its root parameter except to
obtain an fs_info pointer. We can obtain that from trans->root->fs_info
for now and from trans->fs_info in a later patch.

btrfs_trans_handle->root is documented as for use for confirming
that the root passed in to start the transaction is the same as the
one ending it. It's used in several places when an fs_info pointer
is needed, so let's just add an fs_info pointer directly. Eventually,
the root pointer can be removed.

In btrfs_relocate_chunk, we get a transaction handle via
btrfs_start_trans_remove_block_group, which starts the transaction
using the extent root. When we call btrfs_end_transaction, we're calling
it using the chunk root.

Now that we have a dummy fs_info associated with each test that
uses a root, we don't need the DUMMY_ROOT bit anymore. This lets
us make choices without needing an actual root like in e.g.
