[PATCH linux-next v2 0/3] powerpc/kexec: split CONFIG_CRASH_DUMP out from CONFIG_KEXEC_CORE

From: Hari Bathini
Date: Mon Feb 26 2024 - 05:41:45 EST


This patch series is a follow-up to [1] based on discussions at [2]
about additional work needed to get it working on powerpc.

The first patch in the series makes struct crash_mem available with or
without CONFIG_CRASH_DUMP enabled. The next patch moves kdump specific
code for kexec_file_load syscall under CONFIG_CRASH_DUMP and the last
patch splits other kdump specific code under CONFIG_CRASH_DUMP and
removes dependency with CONFIG_CRASH_DUMP for CONFIG_KEXEC_CORE.

[2] https://lore.kernel.org/all/9101bb07-70f1-476c-bec9-ec67e9899744@xxxxxxxxxxxxx/

Changes in v2:
* Fixed a compile error for POWERNV build reported by Sourabh.
