[Thomas Gleixner]

Dear RT Folks,

I'm pleased to announce the 3.2-rc4-rt6 release.

NOTE: Releases are back to www.kernel.org - the intermediate tglx.de
      release URL is history!

Changes vs. 3.2-rc4-rt5:

  * more acpi raw spinlock annotations (Clark)
    	[acpi-make-ec-lock-raw-as-well.patch] -> stable

The incremental patch against 3.2-rc4-rt5 can be found here:

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.2/incr/patch-3.2-rc4-rt5-rt6.patch.bz2    

and is also appended below.


The RT patch against 3.2-rc4 can be found here:
