linux-toradex.git/arch/s390/include/asm/cache.h, branch v3.0.95 Linux kernel for Apalis and Colibri modules [S390] net: provide architecture specific NET_SKB_PAD 2011-02-17T12:13:59+00:00 Horst Hartmann horsth@linux.vnet.ibm.com 2011-02-17T12:13:59+00:00 dd30ac327481f1663b6526fa9fa078569188b7cc NET_SKB_PAD has been increased from 32 to 64 and later to max(32, L1_CACHE_BYTES). This led to a 25% throughput decrease for streaming workloads accompanied by a 37% CPU cost increase on s390. Define a architecture specific NET_SKB_PAD with the old value of 32.
