Aside from my general "uh, why?" stance, I'm very very hesitant to integrate anything in the kernel that doesn'.t have released patches on the toolchain side. Also, which uClibc? The old and crusty uClibc that uses the horrible linuxthreads, or the somewhat less crusty that just switched to NPTL (which hasn't been verified on normal PowerPC that I recall).

I'm not meeting to detract here, but the Kconfig should be dependent on && BROKEN until the above is fixed. josh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
