[PATCH] tty/serial : Add I2C support to Max310x driver (linux-3.8.13)

MAX3107/8 chip supports both SPI and I2C protocol. Currently, max310x driver support only SPI protocol. This patch adds I2C support to the driver. With I2C support, we have added bulk read/write functionality which can be enabled using BULK_RW_ENABLE variable. Signed-off-by: Meghan Saitwal

[PATCH 0/3] OPTPROBES for powerpc

This is the patchset of the kprobes jump optimization (a.k.a OPTPROBES)for powerpc. Kprobe being an inevitable tool for kernel developers, enhancing the performance of kprobe has got much importance. Currently kprobes inserts a trap instruction to probe a running kernel. Jump optimization allows

[PATCH 1/3] arch/powerpc : Add detour buffer support for optprobes

Detour buffer contains instructions to create an in memory pt_regs. After the execution of prehandler a call is made for instruction emulation. The NIP is decided after the probed instruction is executed. Hence a branch instruction is created to the NIP returned by emulate_step(). Instruction

Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_ops structures that have this property can be declared as const

[PATCH v2 3/3] powerpc/mm: Speed up computation of base and actual page size for a HPTE

This replaces a 2-D search through an array with a simple 8-bit table lookup for determining the actual and/or base page size for a HPT entry. The encoding in the second doubleword of the HPTE is designed to encode the actual and base page sizes without using any more bits than would be needed
