[PATCH v4 2/2] powerpc/kexec: move kexec files into a dedicated subdir.
From: Christophe Leroy
Date: Tue Oct 29 2019 - 08:14:02 EST
arch/powerpc/kernel/ contains 8 files dedicated to kexec.
Move them into a dedicated subdirectory.
Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxx>
---
v2: moved crash.c as well as it's part of kexec suite.
v3: renamed files to remove 'kexec' keyword from names.
v4: removed a ifdef in kexec/Makefile
