| H A D | Makefile | bba49665 Wed Dec 22 07:07:31 CST 2021 Christophe Leroy <christophe.leroy@csgroup.eu> powerpc/32: Fix boot failure with GCC latent entropy plugin
Boot fails with GCC latent entropy plugin enabled.
This is due to early boot functions trying to access 'latent_entropy'
global data while the kernel is not relocated at its final
destination yet.
As there is no way to tell GCC to use PTRRELOC() to access it,
disable latent entropy plugin in early_32.o and feature-fixups.o and
code-patching.o
Fixes: 38addce8b600 ("gcc-plugins: Add latent_entropy plugin")
