Subject: [PATCH] Increase SECTION_MAP_LAST_BIT to 4
References: bsc#1144708
Git-commit: 7bdb468c2c99dd780c9a5321f93c79cbfdce2527
Upstream: merged
kernel commit 326e1b8f83a4 ("mm/sparsemem: introduce a SECTION_IS_EARLY
flag") added the flag to mem_section->section_mem_map value, and it caused
makedumpfile an error like the following:
readmem: Can't convert a virtual address(fffffc97d1000000) to physical address.
readmem: type_addr: 0, addr:fffffc97d1000000, size:32768
__exclude_unnecessary_pages: Can't read the buffer of struct page.
create_2nd_bitmap: Can't exclude unnecessary pages.
To fix this, SECTION_MAP_LAST_BIT needs to be updated. The bit has not
been used until the addition, so we can just increase the value.
