45 45 # The mess below is designed to pick the right set of objects to build and/or
46 46 # lint. We have three flavors:
47 47 #
48 48 # 1. proc and raw modules. Only $(MODOBJS) are built.
49 49 # 2. kvm modules for systems without kmdb. Only $(MODOBJS) are built.

52 52 # Complicating matters, we'd like to make the distinction between 2 and 3 before
53 53 # this Makefile is loaded. By default, we'll assume that all kvm modules should

158 158 # kmdb dmods must *not* stray from the module API. To ensure that they don't,
159 159 # we try to link them, at build time, against an object that exports the symbols
160 160 # that they can legally use. The link test object is, however, only built when
161 161 # kmdb itself is built. Requiring module developers to build kmdb first would
162 162 # be painful, so by default, module-level builds don't do the link test (the
163 163 # $(POUND_SIGN) assignment below takes care of that). Builds of the entire
164 164 # tree can, however, guarantee the construction of kmdb first, and as such can
165 165 # override the setting of $(KMDB_LINKTEST_ENABLE). This override causes the
166 166 # link test to be run.
