Here's the summary: Three fixes that didn't make 4.2-stable: - a -Os build might compile the kernel using the MIPS16 instruction set but the R2 optimized inline functions in <uapi/asm/swab.h> are implemented using 32-bit wide instructions which is invalid. - a build error in pgtable-bits.h for a particular kernel configuration. - accessing registers of the CM GCR might have been compiled to use 64 bit accesses but these registers are onl 32 bit wide. And also a few new bits: - move the ATH79 GPIO driver to drivers/gpio - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h, change ATH79 accordingly. - fix definition of pgprot_writecombine - add an implementation of dma_map_ops.mmap - fix alignment of quiet build output for vmlinuz link - BCM47xx: Use kmemdup rather than duplicating its implementation - Netlogic: Fix 0x0x prefixes of constants. - merge Bjorn Helgaas' series to remove most of the weak keywords from function declarations. - CP0 and CP1 registers are best considered treated as unsigned values to avoid large values from becoming negative values. - improve support for the MIPS GIC timer. - enable common clock framework for Malta and SEAD3. - a number of improvments and fixes to dump_tlb(). - document the MIPS TLB dump functionality in Magic SysRq. - Cavium Octeon CN68XX improvments. - NetLogic improvments. - irq: Use access helper irq_data_get_affinity_mask. - handle MSA unaligned accesses. - a number of R6-related math-emu fixes. - support for I6400. - improvments to MSA support. - add uprobes support. - move from deprecated __initcall to arch_initcall. - remove finish_arch_switch(). - IRQ cleanups by Thomas Gleixner. - migrate to new 'set-state' interface. - random small cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (148 commits) MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.

| * MIPS: Remove all the uses of custom gpio.hAlban Bedel2015-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.

* MIPS: AR7: rewrite of cpmac_get_mac()Alexander Clouter2010-08-05
| | | | | | | | | | | | | | Shamelessly stealing wisdom from pasemi_mac.c, I found char2hex() could be replaced with a single call to sscanf(), looks cleaner to me at least. The result is 100 bytes trimmed off the size of a compiled cpmac_get_mac() and as an extra bonus it grumbles and gracefully fails over to using random_ether_addr() when an attempt to parse an invalid MAC address is made.
