H A D | fadump.h | diff eae0dfcc44320c79a05637534d59af4643b2ee7b Thu Jun 01 12:21:26 CDT 2017 Hari Bathini <hbathini@linux.vnet.ibm.com> powerpc/fadump: avoid holes in boot memory area when fadump is registered
To register fadump, boot memory area - the size of low memory chunk that is required for a kernel to boot successfully when booted with restricted memory, is assumed to have no holes. But this memory area is currently not protected from hot-remove operations. So, fadump could fail to re-register after a memory hot-remove operation, if memory is removed from boot memory area. To avoid this, ensure that memory from boot memory area is not hot-removed when fadump is registered.
