Same here : why isn't this on by default when SPU_FS and OPROFILE are
enabled ?

[2.6.24 patch] Fix Cell OProfile support

From: Mathieu Desnoyers <hidden>
Date: 2007-12-29 16:14:32 

This patch restores the Cell OProfile support that was killed by
commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9.

It puts it in arch/powerpc/Kconfig. Since I don't see any good reason to leave
this as a supplementary user-selectable option, it is now automatically enabled
whenever SPU_FS and OPROFILE are enabled.

This one has already been superceded by the fix in 
aed3a8c9bb1a8623a618232087c5ff62718e3b9a, which made CONFIG_OPROFILE_CELL an
automatically selected option, from arch/powerpc/platforms/cell/Kconfig.

Great, so my patch should be dropped. Thanks!
