Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 

Pull crypto update from Herbert Xu:
 - add multibuffer infrastructure (single_task_running scheduler helper,
   OKed by Peter on lkml.
 - add SHA1 multibuffer implementation for AVX2.
 - reenable "by8" AVX CTR optimisation after fixing counter overflow.
 - add APM X-Gene SoC RNG support.
 - SHA256/SHA512 now handles unaligned input correctly.
 - set lz4 decompressed length correctly.
 - fix algif socket buffer allocation failure for 64K page machines.
 - misc fixes

APM X-Gene SoC random number generator.



Required properties:



- compatible  : should be "apm,xgene-rng"

- reg         : specifies base physical address and size of the registers map

- clocks      : phandle to clock-controller plus clock-specifier pair

- interrupts  : specify the fault interrupt for the RNG device



Example:



	rng: rng@10520000 {

		compatible = "apm,xgene-rng";

		reg = <0x0 0x10520000 0x0 0x100>;

		interrupts =   <0x0 0x41 0x4>;

		clocks = <&rngpkaclk 0>;

	};
