Subject[PATCH] powerpc: define the variable 'uaccess_flush' as static
Date
The variable 'uaccess_fulsh' is not referenced outside the file. Perhaps we
should define it as static to avoid the warning as follows:

arch/powerpc/kernel/setup_64.c:953:6: warning: symbol 'uaccess_flush'
was not declared. Should it be static?
