2020-02-21bootconfig: Add append value operator supportMasami Hiramatsu
Add append value operator "+=" support to bootconfig syntax. With this operator, user can add new value to the key as an entry of array instead of overwriting. For example, foo = bar ... foo += baz Then the key "foo" has "bar" and "baz" values as an array.

2020-02-21bootconfig: Prohibit re-defining value on same keyMasami Hiramatsu
Currently, bootconfig adds a new value on the existing key to the tail of an array. But this looks a bit confusing because an admin can easily rewrite the original value in the same config file. This rejects the following value re-definition. key = value1 ... key = value2 You should rewrite value1 to value2 in this case.

2020-02-21spi: spidev: Fix CS polarity if GPIO descriptors are usedLukas Wunner
Commit f3186dd87669 ("spi: Optionally use GPIO descriptors for CS GPIOs") amended of_spi_parse_dt() to always set SPI_CS_HIGH for SPI slaves whose Chip Select is defined by a "cs-gpios" devicetree property. This change broke userspace applications which issue an SPI_IOC_WR_MODE ioctl() to an spidev: Chip Select polarity will be incorrect unless the application is changed to set SPI_CS_HIGH. And once changed, it will be incompatible with kernels not containing the commit. Fix by setting SPI_CS_HIGH in spidev_ioctl() (under the same conditions as in of_spi_parse_dt()).

Also involves extraction of the struct drm_i915_private device from various intel types for use in the macros.

2020-02-21phy: brcm-sata: Correct MDIO operations for 40nm platformsFlorian Fainelli
The logic to write to MDIO registers on 40nm platforms was wrong because it would use the port number as an offset from the base address rather than the bank address of the PHY. This is hardly noticeable because the only programming we do is enabling SSC or not, which is not really causing an observable functional change. Correct that mistake by passing down the struct brcm_sata_port structure down to the brcm_sata_mdio_wr() and brcm_sata_mdio_rd() functions and do the proper offsetting for 28nm, respectively 40nm platforms from there. This means that brcm_sata_pcb_base() is now useless and is therefore removed.

2020-02-20bnxt_en: Issue PCIe FLR in kdump kernel to cleanup pending DMAs.Vasundhara Volam
If crashed kernel does not shutdown the NIC properly, PCIe FLR is required in the kdump kernel in order to initialize all the functions properly.

2020-02-20bnxt_en: Improve device shutdown method.Vasundhara Volam
Especially when bnxt_shutdown() is called during kexec, we need to disable MSIX and disable Bus Master to completely quiesce the device. Make these 2 calls unconditionally in the shutdown method.

2020-02-20net: netlink: cap max groups which will be considered in netlink_bind()Nikolay Aleksandrov
Since nl_groups is a u32 we can't bind more groups via ->bind (netlink_bind) call, but netlink has supported more groups via setsockopt() for a long time and thus nlk->ngroups could be over 32. Recently I added support for per-vlan notifications and increased the groups to 33 for NETLINK_ROUTE which exposed an old bug in the netlink_bind() code causing out-of-bounds access on archs where unsigned long is 32 bits via test_bit() on a local variable. Fix this by capping the maximum groups in netlink_bind() to BITS_PER_TYPE(u32), effectively capping them at 32 which is the minimum of allocated groups and the maximum groups which can be bound via netlink_bind(). CC: Christophe Leroy <christophe.leroy@c-s.fr> CC: Richard Guy Briggs <rgb@redhat.com> Fixes: 4f520900522f ("netlink: have netlink per-protocol bind function return an error code.")

2020-02-20net: thunderx: workaround BGX TX Underflow issueTim Harvey
While it is not yet understood why a TX underflow can easily occur for SGMII interfaces resulting in a TX wedge. It has been found that disabling/re-enabling the LMAC resolves the issue.
