2013-03-27	Force work_restart to be 128-byte aligned.HEAD cell-be-optimizations	David Barksdale
	This fixes a bug on my system where mfc_get was failing on work_restart_pointer because it was not 128-byte aligned.
2011-12-31	Set hashes_done variable to 0 in order not to confuse valgrind	Siarhei Siamashka
	This variable is set by SPU code, but valgrind can't see it and complains.
2011-12-29	Added Cell/BE optimizations	Siarhei Siamashka
	Linux on PS3 gets a huge boost in litecoin mining performance. Cell/BE support should be detected and enabled automatically by autotools. The miner threads are first allocated to the available SPU cores (typically 6). The remaining threads are allocated on PPU. There will be 8 threads total on PS3: 6 SPU threads and 2 PPU threads. Each SPU core provides ~5.4 khash/s if compiled with spu-elf-gcc 4.6 The performance may vary for different gcc versions, older ones are typically slower.
2011-12-29	Use gcc vector extensions for SIMD scrypt key derivation function	Siarhei Siamashka
	The code can be compiled for different architectures from the same source starting with gcc 4.7. But SSE2/Altivec/SPU targets have compatibility wrappers, which also allow the use of older versions of gcc. Two hashes are processed at the same time, so twice bigger scratch buffer is needed (~256K vs. ~128K). Speedup on Cell PPU (32-bit), single thread, 3.2GHz: ~0.58 khash/s -> ~1.79 khash/sec

2011-06-09	Linux + x86_64 optimisations.	ckolivas
	Add likely() macro. Optimise a few obvious code paths with likely/unlikely. Change algo to sse2_amd64 by default. Move priority change to worker threads only. Detect number of CPUs and set default number of threads == CPUs. Add scheduling policy change to worker threads to SCHED_IDLE first and fallback to SCHED_BATCH on linux. Don't error when failing to set priority. Add CPU affinity and bind worker threads to CPUs when number of threads is a multiple of number of CPUs. Update NEWS with changes.

2011-02-03	Add --retry-pause, to set length of pause time between failure retries	Jeff Garzik

2011-02-03	Continue scanhash, even if high 32 bits are zero.	Jeff Garzik
	Previously, we would stop the scan if the high 32 bits of the hash were zero, as a quick shortcut for testing the full hash. If this quick test succeeded, we would pass the work to the server for full validation. Change this logic to perform full validation inside minerd, so that work may be resumed more quickly if hash > target.
