Subject: [PATCH] rs6000: Remove useless toc-fusion option
Date: Wed, 1 Sep 2021 14:56:51 +0800 [thread overview]

Hi!
Option toc-fusion was intended for Power9 toc fusion previously,
but Power9 doesn't support fusion at all eventually, this patch
is to remove this useless option.
Is it ok for trunk?
BR,
Kewen
