Use SYSDIR to reference to the top of the sys hierarchy. Define SYSDIR relative to .CURDIR if not already defined. This makes the makefiles more readable but also more re-usable and adaptable. Obtained from: Juniper Networks, Inc. 2014-03-06 01:59:13 +00:00			`SYSDIR?= ${.CURDIR}/../../..`

- For kernel compiled only with KDTRACE_HOOKS and not any lock debugging option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].

opensolaris code: translate INVARIANTS to DEBUG and ZFS_DEBUG Do this by forcing inclusion of sys/cddl/compat/opensolaris/sys/debug_compat.h via -include option into all source files from OpenSolaris. Note that this -include option must always be after -include opt_global.h. Additionally, remove forced definition of DEBUG for some modules and fix their build without DEBUG. Also, meaning of DEBUG was overloaded to enable WITNESS support for some OpenSolaris (primarily ZFS) locks. Now this overloading is removed and that use of DEBUG is replaced with a new option OPENSOLARIS_WITNESS. MFC after: 17 days 2013-08-06 15:51:56 +00:00
