Subject: [PATCH] relocatable kernel: Fix kallsyms on avr32 after relocatable kernel changes
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2c22d8baa98a92022acb85b0b7c6f4a60df55f47;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] relocatable kernel: Fix kallsyms on avr32 after relocatable kernel changes

o On some platforms like avr32, section init comes before .text and
  not necessarily a symbol's relative position w.r.t _text is positive.
  In such cases assembler detects the overflow and emits warning. This
  patch fixes it.
