Subject: openrisc: Use the declarations provided by <asm/sections.h>
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=be5940c9fd2fa1905fab4353bb9c7051d088d824;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

openrisc: Use the declarations provided by <asm/sections.h>

Openrisc's private vmlinux.h duplicates a few definitions that are already
provided by asm-generic/sections.h. The former is used by setup.c only,
while the latter is already used everywhere else.

Convert setup.c to use the generic version:
  - Include <asm/sections.h>,
  - Remove the (slightly different) extern declarations,
  - Remove the no longer needed address-of ('&') operators.
