clang warns about what seems to be an unintended use of an obscure C
language feature where a forward declaration of an array remains usable
when the final definition is never seen:
drivers/net/ethernet/ti/davinci_emac.c:1694:34: error: tentative array definition assumed to have one element [-Werror]
static const struct of_device_id davinci_emac_of_match[];
There is no harm in always enabling the device tree matching code here,
and it makes the code behave in a more conventional way aside from
avoiding the warning.

Pull btrfs updates from David Sterba:
"This contains usual mix of new features, core changes and fixes; full
list below. I'm planning second pull request, with a few more fixes
that arrived recently but too close to merge window, will send it next
week.
New features:
- support zstd compression levels
- new ioctl to unregister a device from the module (ie. reverse of
device scan)
- scrub prints a message to log when it's about to start or finish
Core changes:
- qgroups can now skip part of a tree that does not get updated
during relocation, because this does not affect the quota
accounting, estimated speedup in run time is about 20%
- the compression workspace management had to be enhanced due to zstd
requirements
- various enospc fixes, when there's high fragmentation the
over-reservation can cause ENOSPC that might not happen after a
flush, in such cases try to wait if the situation improves
Fixes:
- various ioctls could overwrite previous return value if
copy_to_user fails, fix this so the original error is reported
- more reclaim vs GFP_KERNEL fixes
- other cleanups and refactoring
- fix a (valid) lockdep warning in a test when device replace is
destroying worker threads
- make qgroup async transaction commit more aggressive, this avoids
some 'quota limit reached' errors if there are not enough data to
trigger transaction in order to flush
- fix deadlock between snapshot deletion and quotas when backref
walking is called from context that already holds the same locks
- fsync fixes:
- fix fsync after succession of renames of different files
- fix fsync after succession of renames and unlink/rmdir"

Non-zero imm value in the second part of the ldimm64 instruction for
BPF_PSEUDO_MAP_FD is invalid, and thus must be rejected. The map fd
only ever sits in the first instructions' imm field. None of the BPF

are rewritten into insn[0].{src_reg,imm}. Add a test case to the BPF

The kernel provides the macro MODULE_DEVICE_TABLE() where driver authors
can specify their device type and their array of device_ids and thereby
trigger the generation of the appropriate MODULE_ALIAS() output. This is
opposed to having to specify one MODULE_ALIAS() for each device. The WMI
device type is currently not supported.
While using MODULE_DEVICE_TABLE() does increase the complexity as well
as spreading out the implementation across the kernel, it does come with
some benefits too;
* It makes different drivers look more similar; if you can specify the
array of device_ids any device type specific input to MODULE_ALIAS()
will automatically be generated for you.
* It helps each driver avoid keeping multiple versions of the same
information in sync. That is, both the array of device_ids and the
potential multitude of MODULE_ALIAS()'s.
Add WMI support to MODULE_DEVICE_TABLE() by adding info about struct
wmi_device_id in devicetable-offsets.c and add a WMI entry point in
file2alias.c.
The type argument for MODULE_DEVICE_TABLE(type, name) is wmi.

In preparation for adding WMI support to MODULE_DEVICE_TABLE() move the
definition of struct wmi_device_id to mod_devicetable.h and inline
guid_string in the struct.
Changing guid_string to an inline char array changes the loop conditions
when looping over an array of struct wmi_device_id. Therefore update
wmi_dev_match()'s loop to check for an empty guid_string instead of a
NULL pointer.

of UINT_MAX.
However, data points so far in the future don't matter for idle
state selection anyway, so change the initial threshold value in
get_typical_interval() to INT_MAX which will cause more "outlying"
data points to be discarded without affecting the selection result.

is properly accounted for.

A bunch of related changes lumped together:
* Create prog_tests and verifier output directories; these don't exist with
out-of-tree $(OUTPUT)
* Add missing -I (via separate TEST_{PROGS,VERIFIER}_CFLAGS) for the main tree
($(PWD) != $(OUTPUT) for out-of-tree)
* Add libbpf.a dependency for test_progs_32 (parallel make fails otherwise)
* Add missing "; \" after "cd" when generating test.h headers
Tested by:
$ alias m="make -s -j$(nproc)"

$ m -C tools/lib/bpf/ clean

Add a test on egress that a large TCP packet successfully goes through
the lwt+bpf encap tunnel.
Although there is no direct evidence that GSO worked, as opposed to
e.g. TCP segmentation or IP fragmentation (maybe a kernel stats counter
should be added to track the number of failed GSO attempts?), without
the previous patch in the patchset this test fails, and printk-debugging
showed that software-based GSO succeeded here (veth is not compatible with
SKB_GSO_DODGY, so GSO happens in the software stack).
Also removed an unnecessary nodad and added a missed failed flag.

GSO needs inner headers and inner protocol set properly to work.
skb->inner_mac_header: skb_reset_inner_headers() assigns the current
mac header value to inner_mac_header; but it is not set at the point,
so we need to call skb_reset_inner_mac_header, otherwise gre_gso_segment
fails: it does
int tnl_hlen = skb_inner_mac_header(skb) - skb_transport_header(skb);
...
if (unlikely(!pskb_may_pull(skb, tnl_hlen)))
...
skb->inner_protocol should also be correctly set.

Commit 0918f18c71 ("crypto: s5p - add AES support for Exynos5433")
introduced bug in dereferencing clk_names[1] on platforms different from
Exynos5433. On Exynos board XU3 call trace is:
"Unable to handle kernel paging request at virtual address 00004000"
(strcmp) from [<c0774014>] (of_property_match_string+0x58/0xd0)
...
(devm_clk_get) from [<c075c248>] (s5p_aes_probe+0xd4/0x4a0)
(s5p_aes_probe) from [<c059dbc4>] (platform_drv_probe+0x6c/0xa4)
Fix this by setting array clk_names size to 2.
