[PATCH] Significantly reduce memory usage of genattrtab

2016-11-15 Thread Bernd Edlinger
Hi! The genattrtab build-tool uses way too much memory in general. I think there is no other build step that uses more memory. On the currently trunk it takes around 700MB to build the ARM latency tab files. I debugged that yesterday and found that this can be reduced to 8MB (!). Yes, really.
