Will 2.6.24.2 be a PREEMPT kernel?

Previous "official" kernel was patched with Ingo Molnar's real time patch, AFAIK. The one which is in core at the moment isn't, or at least I think it isn't. It's quite understandable as 2.6.24.1 doesn't have a corresponding real time patch. Will 2.6.24.2 be patched, considered there is an official patch for it?
Anyone have any info on this?

The kernel26 package does not use the rt patch, and never has. There is a kernel26rt package in the AUR.

You're claiming that it never did? But the kernel 2.6.23-ARCH was a PREEMPT kernel, so how was it made then?

2.6.24-ARCH is also PREEMPT:

$ uname -a
Linux tk-i5ka 2.6.24-ARCH #1 SMP PREEMPT Wed Feb 20 18:20:46 UTC 2008 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux

It's a feature in the mainline kernel, no patches required:
Processor Type and Features
--> Preemption Model
     --> Preemptible Kernel (Low-Latency Desktop)

I have the vanilla kernel from kernel.org

$ uname -a
... SMP PREEMPT Sat Feb 23 10:18:12 GMT 2008 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux

$ grep PREEMPT /usr/src/linux/.config
CONFIG_PREEMPT=y
CONFIG_PREEMPT_BKL=y

O.K., thanks for the explanation I couldn't find PKGBUILD of a rt-kernel in AUR. Could someone post a direct link?
