[Xenomai-core] [announce] Xenomai v2.5.5

[Gilles Chanteperdrix <gilles.chanteperdrix@xenomai.org>]

Hi,

Xenomai 2.5.5, aka "Ghosts", is available:
http://download.gna.org/xenomai/stable/xenomai-2.5.5.tar.bz2

It contains bug fixes for:
- the x86 I-pipe issue, which caused freeze-on-boot issue, very 
reproducible with grub 2
- a ppc I-pipe issue, which involved unaligned access to floating point 
values
- the debian patch generation script, which caused invalid patches to be
generated for recent kernel releases
- a few compilation issues with recent compilers and or innfrequently 
used compilation options
- issues with using fork with process-private user-space mutexes

And improvements:
- of the user-space latency on all platforms by optimizing the RPI code 
and the relax code
- of the ARM support to code, in order to support SMP systems
- of the analogy stack by Alexis
- of the user-space latency on ARM in general and OMAP3 in particular, 
as a result of some work both on Xenomai timer code and on the I-pipe 
patch
- of the scheduler "resched" bit handling by simplifying it, following 
the correction of an incorrect warning

Note: Xenomai 2.5.5 is the last release to contain a patch for Linux 2.4
on x86 and to export kernel-mode services to non GPL modules.

Enjoy.
