From: Luis R. Rodriguez <mcgrof@xxxxxxxxxxxxx> While testing ckmake cross compiling compat through different kernels I realized that compat was failing to build on some kernels but compat-wireless was not. The reason for this turned out to be that compat did not have an autoconf for the CONFIG_COMPAT_KERNEL_* variables. In order to make use of a variable properly in code on kernel we need two things: a makefile equivalent and a header file that defines it. The compat project had only makefile variable generation while compat-wireless had makefile variable generation with a *few* variables propagated to actual code. To avoid issues with this any further I've decided to try merging the autoconf effort for both projects and taking leads on what compat does first. compat then does the CONFIG_COMPAT_KERNEL_* trickery and generates a clean .config for us. This in turn generates our compat's compat_autoconf.h. The compat-wireless project leverages this work by dropping its own Makefile hackery in favor of the same work and later also uses the same .config to expand its own compat_autoconf.h. John, I could use some extra help on reviewing the RHEL stuff. I'm going to push this stuff out now to help with testing. compat: Luis R.
