Do you actually need anything in the ps3 patch?

It's neater to create a file in your kernel directory called
'localversion'.

A bit of digging will show that the PS3 patch introduces this hunk,
which is the start of your problems:

diff --git a/arch/powerpc/Kconfig b/arch/powerpc/Kconfig
index 3934e26..0d67f29 100644
--- a/arch/powerpc/Kconfig
+++ b/arch/powerpc/Kconfig
@@ -218,6 +218,8 @@ source "init/Kconfig"
 source "arch/powerpc/sysdev/Kconfig"
 source "arch/powerpc/platforms/Kconfig"
 
+source "arch/powerpc/perfmon/Kconfig"


But that file doesn't exist. For starters you should try removing that
line and see if that's enough to get the kernel building.

cheers
