1. ppc_override_l2cr and ppc_override_l2cr_value are only used in
    l2cr_init() function, remove them and used *l2cr directly.
2. has_l2cache is not used outside of the file, so mark it static and
    do not initialise statics to 0.

Fixes the following warning:

arch/powerpc/platforms/powermac/setup.c:74:5: warning: symbol
'ppc_override_l2cr' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:75:5: warning: symbol
'ppc_override_l2cr_value' was not declared. Should it be static?
arch/powerpc/platforms/powermac/setup.c:76:5: warning: symbol
'has_l2cache' was not declared. Should it be static?

You could have replaced printk(KERN_INFO by pr_info(

Thanks, I have replaced printk(KERN_INFO by pr_info( in PATCH v3.


Otherwise
