x86: fix csum_partial() export
Fix this symbol export problem: Building modules, stage 2. MODPOST 193 modules ERROR: "csum_partial" [fs/reiserfs/reiserfs.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 This is due to a known weakness of symbol exports: if a symbol's only in-core user is an EXPORT_SYMBOL from a lib-y section, the symbol is not linked in. The solution is to move the export to x8664_ksyms_64.c - but the real solution would be to fix kbuild. Signed-off-by: Ingo Molnar <mingo@elte.hu>
