Subject: microblaze: Do not use _start in vmlinux
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ca28b510163a55df6260652056bfc60c4cf8aca1;p=linux-beck.git

microblaze: Do not use _start in vmlinux

_start symbol stores physical address where kernel is.
Gdb uses this symbol for their purpose that's why
we have to rename it.
