Nov 7 17:47:57 2019 +0100 # # powerpc/fadump: when fadump is supported register the fadump sysfs files. # # Currently it is not possible to distinguish the case when fadump is # supported by firmware and disabled in kernel and completely unsupported # using the kernel sysfs interface. User can investigate the devicetree # but it is more reasonable to provide sysfs files in case we get some # fadumpv2 in the future. # # With this patch sysfs files are available whenever fadump is supported # by firmware. # # There is duplicate message about lack of support by firmware in # fadump_reserve_mem and setup_fadump. Remove the duplicate message in # setup_fadump. # # Signed-off-by: Michal Suchanek <msuchanek@suse.de> # Reviewed-by: Hari Bathini <hbathini@linux.ibm.com> # Signed-off-by: Michael Ellerman
