Subject: powerpc/smp: Remove unused generic_cpu_enable()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b527d07114fdab83f39040c69b4b0a4b1b232c16;p=openwrt%2Fstaging%2Fblogic.git

powerpc/smp: Remove unused generic_cpu_enable()

Nobody uses it, besides we should always use the normal __cpu_up
path anyways
