Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes. The executive summary: - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY. - Avoid useless rebuilds for zboot. - jz4780: Add NEMC, BCH and NAND device tree nodes - Initial support for the MicroChip's DT platform. As all the device drivers are missing this is still of limited use. - Some Loongson3 cleanups. - The unavoidable whitespace polishing. - Reduce clock skew when synchronizing the CPU cycle counters on CPU startup. - Add MIPS R6 fixes. - Lots of cleanups across arch/mips as fallout from KVM. - Lots of minor fixes and changes for IEEE 754-2008 support to the FPU emulator / fp-assist software. - Minor Ralink, BCM47xx and bcm963xx platform support improvments. - Support SMP on BCM63168" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (84 commits) MIPS: zboot: Add support for serial debug using the PROM MIPS: zboot: Avoid useless rebuilds MIPS: BMIPS: Enable ARCH_WANT_OPTIONAL_GPIOLIB MIPS: bcm63xx: nvram: Remove unused bcm63xx_nvram_get_psi_size() function MIPS: bcm963xx: Update bcm_tag field image_sequence MIPS: bcm963xx: Move extended flash address to bcm_tag header file MIPS: bcm963xx: Move Broadcom BCM963xx image tag data structure MIPS: bcm63xx: nvram: Use nvram structure definition from header file MIPS: bcm963xx: Add Broadcom BCM963xx board nvram data structure MAINTAINERS: Add KVM for MIPS entry MIPS: KVM: Add missing newline to kvm_err() MIPS: Move KVM specific opcodes into asm/inst.h MIPS: KVM: Use cacheops.h definitions MIPS: Break down cacheops.h definitions MIPS: Use EXCCODE_ constants with set_except_vector() MIPS: Update trap codes MIPS: Move Cause.ExcCode trap codes to mipsregs.h MIPS: KVM: Make kvm_mips_{init,exit}() static MIPS: KVM: Refactor added offsetof()s MIPS: KVM: Convert EXPORT_SYMBOL to _GPL ...

2016-01-22NTB: Fix macro parameter conflict with field nameAllen Hubbe1-2/+3
If the parameter given to the macro is replaced throughout the macro as it is evaluated. The intent is that the macro parameter should replace the only the first parameter to container_of(). However, the way the macro was written, it would also inadvertantly replace a structure field name. If a parameter of any other name is given to the macro, it will fail to compile, if the structure does not contain a field of the same name. At worst, it will compile, and hide improper access of an unintended field in the structure. Change the macro parameter name, so it does not conflict with the structure field name.

2016-01-21IB/sa: Fix netlink local service GFP crashKaike Wan1-2/+6
The rdma netlink local service registers a handler to handle RESOLVE response and another handler to handle SET_TIMEOUT request. The first thing these handlers do is to call netlink_capable() to check the access right of the received skb to make sure that the sender has root access. Under normal conditions, such responses and requests will be directly forwarded to the handlers without going through the netlink_dump pathway (see ibnl_rcv_msg() in drivers/infiniband/core/netlink.c). However, a user application could send a RESOLVE request (not response) to the local service, which will fall into the netlink_dump pathway, where a new skb will be created without initializing the control block. This new skb will be eventually forwarded to the local service RESOLVE response handler. Unfortunately, netlink_capable() will cause general protection fault if the skb's control block is not initialized. This patch will address the problem by checking the skb first.
