0bdf8a8245 eCryptfs: fix a couple type promotion bugs
ECRYPTFS_SIZE_AND_MARKER_BYTES is type size_t, so if "rc" is negative
that gets type promoted to a high positive value and treated as success.

f2281c245d Support Mellanox BlueField SmartNIC (mlx5-updates-2019-02-15)
Bodong Wang says,
 
 BlueField device is a multi-core ARM processor in a highly integrated
 system on chip coupled with the ConnectX interconnect controller.
 BlueField device can be presented in one out of two modes:
 
 - SEPARATED_HOST: ARM processors as a separated and orthogonal host
   like any other external host in the multi-host virtualization model.
 - EMBEDDED_CPU: ARM processors as Embedded CPU (EC) and part of the
   external hosts virtualization model.
 
 While existing driver already supports the device on separated_host
 mode, this patch series focus on the functionalities of embedded_cpu
 mode.
 
 On embedded_cpu mode, BlueField device exposes regular network
 controller PCI function in the BlueField host(e.g, x86). However, a
 separate PCI function called Embedded CPU Physical Function(ECPF) is
 also added to the ARM host side, where standard Linux distributions is
 able to run on the ARM cores. Depends on the NV configuration from
 firmware, ECPF can be the e-switch manager and firmware pages supplier.
 If ECPF is configured as e-switch manager and page supplier, it will
 take over the responsibilities from the PF on BlueField host includes:
 - Owns, controls and manages all e-switch parts, and takes e-switch
   traffic by default. It also should perform ENABLE_HCA for the host
   PF just like a PF does for its VFs.
 - Provides and manages the ICM host memory required for the HCA to
   store various contexts for itself, the PF and VFs belong the
   e-switch it manages.
 
 The PF on BlueField host side is still responsible for:
 - Control its own permanent MAC.
 - PCI and SRIOV configurations and perform ENABLE_HCA for its VFs.
 
 The ECPF can also retrieve information about the external host it
 controls, like host identifier, PCI BDF and number of virtual functions.
 As these parameters may be changed dynamically, an event will be triggered
 to the driver on ECPF side.

cc4b1242d7 vfs: fix preadv64v2 and pwritev64v2 compat syscalls with offset == -1
The preadv2 and pwritev2 syscalls are supposed to emulate the readv and
writev syscalls when offset == -1. Therefore the compat code should
check for offset before calling do_compat_preadv64 and
do_compat_pwritev64. This is the case for the preadv2 and pwritev2
syscalls, but handling of offset == -1 is missing in their 64-bit
equivalent.

This patch fixes that, calling do_compat_readv and do_compat_writev when
offset == -1. This fixes the following glibc tests on x32:
 - misc/tst-preadvwritev2
 - misc/tst-preadvwritev64v2

8a5b403d71 arm64, mm, efi: Account for GICv3 LPI tables in static memblock reserve table
In the irqchip and EFI code, we have what basically amounts to a quirk
to work around a peculiarity in the GICv3 architecture, which permits
the system memory address of LPI tables to be programmable only once
after a CPU reset. This means kexec kernels must use the same memory
as the first kernel, and thus ensure that this memory has not been
given out for other purposes by the time the ITS init code runs, which
is not very early for secondary CPUs.

On systems with many CPUs, these reservations could overflow the
memblock reservation table, and this was addressed in commit:

  eff8962888 ("efi/arm: Defer persistent reservations until after paging_init()")

However, this turns out to have made things worse, since the allocation
of page tables and heap space for the resized memblock reservation table
itself may overwrite the regions we are attempting to reserve, which may
cause all kinds of corruption, also considering that the ITS will still
be poking bits into that memory in response to incoming MSIs.

So instead, let's grow the static memblock reservation table on such
systems so it can accommodate these reservations at an earlier time.
This will permit us to revert the above commit in a subsequent patch.

The following commit:

  a893ea15d764 ("tpm: move tpm_chip definition to include/linux/tpm.h")

introduced a build error when both IMA and EFI are enabled:

    In file included from ../security/integrity/ima/ima_fs.c:30:
    ../security/integrity/ima/ima.h:176:7: error: redeclaration of enumerator "NONE"

What happens is that both headers (ima.h and efi.h) defines the same
'NONE' constant, and it broke when they started getting included from
the same file:

Rework to prefix the EFI enum with 'EFI_*'.

a3419ce335 netfilter: nf_conntrack_sip: add sip_external_media logic
When enabled, the sip_external_media logic will leave SDP
payload untouched when it detects that interface towards INVITEd
party is the same with the one towards media endpoint.

The typical scenario for this logic is when a LAN SIP agent has more
than one IP address (uses a different address for media streams than
the one used on signalling stream) and it also forwards calls to a
voice mailbox located on the WAN side. In such case sip_direct_media
must be disabled (so normal calls could be handled by the SIP
helper), but media streams that are not traversing this router must
also be excluded from address translation (e.g. call forwards).

====================
net: dsa: b53: VLAN and L2 fixes

This patch series contains a collection of fixes to the b53 driver in
order to:

- consistently program the same default VLAN ID when a port is bridged
  or not
- properly account for VLAN filtering being turned on/off and turning
  on ingress VID checking accordingly
- have SYSTEMPORT properly forward BPDU frames to the network stack
  (which it did not)
- do not assume that WoL is supported by the DSA master network device
  we are connected to

far as untagged traffic goes, also, having the CPU port be part of a

fea8335317 net: dsa: b53: Fix default VLAN ID
We were not consistent in how the default VID of a given port was
defined, b53_br_leave() would make sure the VLAN ID would be either 0/1
depending on the switch generation, but b53_configure_vlan(), which is
the default configuration would unconditionally set it to 1. The correct
value is 1 for 5325/5365 series and 0 otherwise. To avoid repeating that
mistake ever again, introduce a helper function: b53_default_pvid() to
factor that out.

8024cc9e85 s390/qeth: split out OSN netdev ops
Rather than special-casing OSN in a number of places, just give this
device type its own netdev_ops structure.

When setting up the OSN net_device, also skip the handling of the
various HW offloads (eg TSO). The device shouldn't be advertising any of
them, and the OSN code paths in qeth don't have support for them.
In particular RX VLAN filtering is not supported, so don't hook up those
callbacks in the netdev_ops.
