- Skip config lock enter/exit for embedded blocks. They have no DVAs, so there is nothing to check under the lock. - Skip CHECKSUM check and properly check PSIZE for embedded blocks. - Add static branch predictions for unlikely conditions. - Do not verify DVAs for blocks already in ARC. ARC hit already "verified" the first (often the only) DVA, and it does not worth to enter/exit config lock for nothing. Some profiles show me up to 3% of CPU saving from this change.
