S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.
TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.
The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.
Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

immdlen field of FW_ETH_TX_PKT_WR is filled in a wrong way,
we must copy the length of all the cpls encapsulated in fw

of CPL_TX_PKT_CORE but we added the length of WR_HDR and it
worked because WR_HDR and CPL_TX_PKT_CORE are of same length.
Add the length of cpl_tx_pkt_core not WR_HDR's. This also

If CONFIG_ARM_SMMU_V3 is enabled, arm64's dma_ops will replace
arm64_swiotlb_dma_ops with iommu_dma_ops. When releasing contiguous
dma memory, the new ops will call the vunmap function which cannot
be run in interrupt context.
Currently, spin_lock_bh is called before vunmap is executed. This
disables BH and causes the interrupt context to be detected to
generate a kernel panic like below:

Meanwhile common code from rtl_hw_start_8169/8101/8168() was moved

11 --> Payload is a Bad Frame with CRC or Alignment Error

Pull x86 fixes from Thomas Gleixner:
"An unfortunately larger set of fixes, but a large portion is
selftests:
- Fix the missing clusterid initializaiton for x2apic cluster
management which caused boot failures due to IPIs being sent to the
wrong cluster
- Drop TX_COMPAT when a 64bit executable is exec()'ed from a compat
task
- Wrap access to __supported_pte_mask in __startup_64() where clang
compile fails due to a non PC relative access being generated.
- Two fixes for 5 level paging fallout in the decompressor:
- Handle GOT correctly for paging_prepare() and
cleanup_trampoline()
- Fix the page table handling in cleanup_trampoline() to avoid
page table corruption.
- Stop special casing protection key 0 as this is inconsistent with
the manpage and also inconsistent with the allocation map handling.
- Override the protection key wen moving away from PROT_EXEC to
prevent inaccessible memory.
- Fix and update the protection key selftests to address breakage and
to cover the above issue
- Add a MOV SS self test"

Currently ip6gre and ip6erspan share single metadata mode device,
using 'collect_md_tun'. Thus, when doing:
ip link add dev ip6gre11 type ip6gretap external
ip link add dev ip6erspan12 type ip6erspan external
RTNETLINK answers: File exists
simply fails due to the 2nd tries to create the same collect_md_tun.
The patch fixes it by adding a separate collect md tunnel device
for the ip6erspan, 'collect_md_tun_erspan'. As a result, a couple
of places need to refactor/split up in order to distinguish ip6gre
and ip6erspan.
First, move the collect_md check at ip6gre_tunnel_{unlink,link} and
create separate function {ip6gre,ip6ersapn}_tunnel_{link_md,unlink_md}.
Then before link/unlink, make sure the link_md/unlink_md is called.
Finally, a separate ndo_uninit is created for ip6erspan. Tested it
using the samples/bpf/test_tunnel_bpf.sh.

Add Renesas R8A77980 GEther support
Here's a set of 3 patches against DaveM's 'net-next.git' repo. They (gradually)
add R8A77980 GEther support to the 'sh_eth' driver, starting with couple new
register bits/values introduced with this chip, and ending with adding a new
'struct sh_eth_cpu_data' instance connected to the new DT "compatible" prop

A handful of fixes. I've been queuing them up a bit too long so the list
is longer than it otherwise would have been spread out across a few -rcs.
In general, it's a scattering of fixes across several platforms, nothing
truly serious enough to point out.
There's a slightly larger batch of them for the Davinci platforms due
to work to bring them back to life after some time, so there's a handful
of regressions, some of them going back very far, others more recent.
There's also a few patches fixing DT on Renesas platforms since they
changed some bindings without remaining backwards compatible, splitting
up describing LVDS as a proper bridge instead of having it as part of the
display unit. We could push for them to be backwards compatible with old
device trees, but it's likely to regress eventually if nobody's actually
using said compatibility.
