           Summary: section mismatch in mm/page_alloc.c vs mm/bootmem.c
           Product: Memory Management
           Version: 2.5
     KernelVersion: 2.6.27-rc4
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Page Allocator
        AssignedTo: akpm at osdl.org
        ReportedBy: blofeldus at yahoo.com


Latest working kernel version: v2.6.26-6380-g8b05c7e
Earliest failing kernel version: v2.6.26-6381-gb61bfa3
Distribution: Fedora 9
Hardware Environment: powerpc
Software Environment: gcc 4.3.1-6
Problem Description:
WARNING: mm/built-in.o(.data+0x80c): Section mismatch in reference from the
variable contig_page_data to the variable .init.data:bootmem_node_data
The variable contig_page_data references
the variable __initdata bootmem_node_data
If the reference is valid then annotate the
variable with __init* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, 


Steps to reproduce:
 make where CONFIG_NEED_MULTIPLE_NODES is not set


Commit b61bfa3c462671c48a51fb5c31af337c5a996a04 declared in mm/bootmem.c:

+bootmem_data_t bootmem_node_data[MAX_NUMNODES] __initdata;

and used in mm/page_alloc.c:

+struct pglist_data contig_page_data = { .bdata = &bootmem_node_data[0] };


Seems both or neither should be __initdata.
