*	libc: Use 8-bytes stores for non-0 memset too	Benjamin Herrenschmidt	2016-08-18	1	-1/+8
\| \| \| \| \| \| \| \|	Memory poisoning hammers this, so let's be a bit smart about it and avoid falling back to byte stores when the data is not 0 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
*	Optimized memset() implementation for POWER	Stewart Smith	2015-06-01	1	-0/+22
\| \| \| \| \| \| \| \| \| \| \| \|	This uses the dcbz instruction to clear cacheline at a time rather than byte at a time. This means that even without high levels of optimization, we dramatically improve boot performance with SKIBOOT_GCOV=1 and probably ever so slightly speed things up for normal builds. We currently just hard-code 128 as cacheline size as all CPUs that skiboot currently boots on have 128 byte cachelines. Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
