Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently. 2011-03-23T16:54:33Z pirofti pirofti@openbsd.org 2011-03-23T16:54:33Z urn:sha1:2fa72412907ae78c4787a4a8f888c5f0486e225c Discussed and okay drahn@.

First pass at removing clauses 3 and 4 from NetBSD licenses. 2008-06-26T05:42:03Z ray ray@openbsd.org 2008-06-26T05:42:03Z urn:sha1:d874cce4b1d9fe6b41c9e4f2117a77d8a4a37b92 Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors.

All architectures other than i386 and amd64 get dummy implementations since at first we'll be replacing operations that are done with "a |= bit" and "a &= ~bit" today. More proper implementations will follow kettenis@, miod@ ok Fix the __asm__ statements and remove the workarounds. 2002-02-15T15:31:58Z art art@openbsd.org 2002-02-15T15:31:58Z urn:sha1:7f724c1ae3cd6fa7f71d87b939961fef90d93480 From NetBSD.
