This commit now removes it altogether since it causes build failures for GENERIC kernels and the various applicable trends are such that one can expect that it these failure will cause more problems than they're worth in the future. These trends include: 1. Alpha was demoted from tier 1 to tier 2 due to lack of active support. The number of people willing to fix build breakages is not likely to increase and those developers that do have the gumption to test MI changes on alpha are not likely to spend time fixing unexpected build failures first. 2. The kernel will only increase in size. Even though stripped-down kernels do link without problems now, compiler optimizations (like inlining) and new (non-optional) functionality will likely cause stripped-down kernels to break in the future as well. So, with my asbestos suit on, get rid of potential problems before they happen. MT5 candidate. Revision Changes Path 1.19 +14 -62 src/sys/alpha/include/atomic.h
