This patch doesn't really belong in the CGU patchset. It should go 
through the MIPS tree.

I see why you include it, but you do not need to have the MACH_JZ4755 
symbol defined anywhere for the "default MACH_JZ4755" to work, it will 
just default to false until the patchset that adds JZ4755 support is 
merged in the MIPS tree.

Cheers,
-Paul
