Cover letter [Xenomai-core] [PATCH 00/13] Generic fast xnsynch support & more

Hopefully the last round, addressing remarks brought up on the last posting. The changes are:

[Patches 7-9]
- define xnsynch_owner_check as xnsynch-implementation-independent way to check provided and current synch owner match (reduces #ifdefs)

[Patches 6 and 9]
- push lockcnt changes to native mutexes into separate patch (patch

[Patch 2]
- switch creation of xeno_current_key etc. from pthread_once to a constructor
- translate pthread_getspecific == NULL into XN_NO_HANDLE (funnily, this shrinks the code on x86-64)

[Patch 13]
- detect SMP feature inconsistency between kernel and userland (but keep SMP off by default for now)

Note that this series (as well as the latter) depends on the VRTX fix of Philippe which is not yet merged into SVN trunk.

Jan

PS: Hope this series is compatible with more mail clients /wrt commenting on the inlined patches.
