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 ...

MIPS: Move KVM specific opcodes into asm/inst.h

2016-01-24T02:31:17Z

The header arch/mips/kvm/opcode.h defines a few extra opcodes which aren't in arch/mips/include/uapi/asm/inst.h. There's nothing KVM specific about them, so lets move them into inst.h where they belong and delete the header. Note that mfmcz_op is renamed to mfmc0_op to match the instruction set manual, and wait_op was already added to inst.h in commit b0a3eae2b943 ("MIPS: inst.h: define COP0 wait op"), merged in v3.16-rc1.

MIPS: inst.h: Fix some instruction descriptions

2016-01-24T00:36:50Z

Fix the description of the microMIPS NOP16 encoding or MM_NOP16, which is not equivalent to the MIPS16 NOP instruction. This is 0x0c00 and represents the microMIPS `MOVE16 $0, $0' operation, whereas MIPS16 NOP is encoded as 0x6500, representing `MOVE $0, $16'. Also fix a typo in `mm_fp0_format' description.

MIPS: math-emu: Correct the emulation of microMIPS ADDIUPC instruction

2016-01-24T00:36:10Z

Emulate the microMIPS ADDIUPC instruction directly in `mips_dsemul'. If executed in the emulation frame, this instruction produces an incorrect result, because the value of the PC there is not the same as where the instruction originated. Reshape code so as to handle all microMIPS cases together. Signed-off-by: Maciej W.

mm: arch: remove duplicate definitions of MADV_FREE

2016-01-21T01:09:18Z

Commits 21f55b018ba5 ("arch/*/include/uapi/asm/mman.h: : let MADV_FREE have same value for all architectures") and ef58978f1eaa ("mm: define MADV_FREE for some arches") both defined MADV_FREE, but did not use the same values. This results in build errors such as ./arch/alpha/include/uapi/asm/mman.h:53:0: error: "MADV_FREE" redefined ./arch/alpha/include/uapi/asm/mman.h:50:0: note: this is the location of the previous definition for the affected architectures.

arch/*/include/uapi/asm/mman.h: : let MADV_FREE have same value for all architectures

2016-01-16T01:56:32Z

For uapi, need try to let all macros have same value, and MADV_FREE is added into main branch recently, so need redefine MADV_FREE for it. At present, '8' can be shared with all architectures, so redefine it to '8'.

mm: define MADV_FREE for some arches

2016-01-16T01:56:32Z

Most architectures use asm-generic, but alpha, mips, parisc, xtensa need their own definitions. This patch defines MADV_FREE for them so it should fix build break for their architectures. Maybe, I should split and feed pieces to arch maintainers but included here for mmotm convenience.

soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF

2016-01-05T03:49:59Z

Expose socket options for setting a classic or extended BPF program for use when selecting sockets in an SO_REUSEPORT group. These options can be used on the first socket to belong to a group before bind or on any socket in the group after bind. This change includes refactoring of the existing sk_filter code to allow reuse of the existing BPF filter validation checks.
