Subject: powerpc/book3e-64/kexec: Set "r4 = 0" when entering spinloop
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ae73e4ccbc91853259d730fd8c5089bdf06a4fa3;p=linux-beck.git

powerpc/book3e-64/kexec: Set "r4 = 0" when entering spinloop

book3e_secondary_core_init will only create a TLB entry if r4 = 0,
so do so.
