Factor the common parts of the Makefile.foo files. This introduces two new files: kern.pre.mk, which contains most of the definitions, and kern.post.mk, which contains most of the rules. I've tested this on i386 and pc98. I have had feedback on the sparc64 port, but no reports from anybody on alpha, ia64 or powerpc. I appologize in advance if I've broken you.

Quick fix for high resolution kernel profiling on i386's. Use -finstrument-functions instead of -mprofiler-epilogue. The former works essentially the same as the latter but has a higher overhead (about 22 more bytes per function for passing unused args to the profiling functions). Removed all traces of the IDENT Makefile variable, which had been reduced to just a place for holding profiling's contribution to CFLAGS (the IDENT that gives the kernel identity was renamed to KERN_IDENT).

COPTS= ${INCLUDES} -D_KERNEL -include opt_global.h
Eliminate the use of commons in the kernel and modules, simplifying the module linking process and eliminating the risks associated with doubly-defined variables. Cases where commons were legitimately used (detection of compiled-in subsystems) have been converted to use sysinits, and any new code should use this or an equivalent practice as a matter of course. Modules can override this behaviour by substituting -fno-common out of ${CFLAGS} in cases where commons are necessary (eg. third-party object modules). Commons will be resolved and allocated space when the kld is linked as part of the module build process, so they will not pose a risk to the kernel or other modules. Provide a mechanism for controlling the export of symbols from the module namespace. The EXPORT_SYMS variable may be set in the Makefile to NO (export no symbols), a list of symbols to export, or the name of a file containing a newline-seperated list of symbols to be exported. Non-exported symbols are converted to local symbols. If EXPORT_SYMS is not set, all global symbols are currently exported. This behaviour is expected to change (to exporting no symbols) once modules have been converted. Reviewed by: peter (in principle) Obtained from: green (kmod_syms.awk)
