![]() exceptions early enough during boot that the kernel will do ithe same. Use lwsync only when compiling for LP64 and revert to the more proven isync when compiling for ILP32. Note that in the end (i.e. between revision 222198 and this change) ILP32 changed from using sync to using isync. As per Nathan the isync is needed to make sure I/O accesses are properly serialized with locks and isync tends to be more effecient than sync. While here, undefine __ATOMIC_ACQ and __ATOMIC_REL at the end of the file so as not to leak their definitions. Discussed with: nwhitehorn |
