Subject: vmlinuz.lds: define OF table sections with macros
X-Git-Tag: v3.16-rc1~47^2~21^2~2^2~13
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=063092883039e49e5edc1f63133dc5ad437361a2;p=linux.git

vmlinuz.lds: define OF table sections with macros

OF table sections all have the same pattern, so create a macro to define
them and insure consistency.
