And reading the MIPS64 v6.04 instruction set manual, I think 0x11/0x12 are _NOT_ transitive and therefore cannot be used to implement the smp_mb__{before,after} stuff. That is, in MIPS speak, those SYNC types are Ordering Barriers, not Completion Barriers. They need not be globally performed.

...it does you _must_ use them, however unlikely. 2) the changelog _completely_ fails to explain the sync 0x11 and sync 0x12 semantics nor does it provide a publicly accessible link to documentation that does. 3) it really should have explained what you did with smp_llsc_mb/smp_mb__before_llsc() in _detail_. And I agree that ideally it should be split into parts. Seriously, this is _NOT_ OK.

All, I would like to announce our Official CentOS CD/DVD Vendor Program. We currently have 3 vendors, and 2 more who are putting together their information. (Not bad ... the official program has been going for less than 12 hours :) The details of the program (how to get in it, what they give back to the CentOS Project, etc.) are here: http://www.centos.org/images/CentOS_CD_Vendors.pdf Here is
