Re: [OE-core] [PATCH] db: disable the ARM assembler mutex code

Some more explanations: Berkeley DB's assembly mutex code for arm is related with arm arch version. The old version DB code uses old arm instruction (such as swpb), which isn't supported by new arm arch (such as armv7). The new version DB (maybe from 6.1.29 or 6.1.26) uses new arm
