As I find out it is normal behavior when CONFIG_XEN is enabled in this
kernel version. Unlike mainline kernel this version establish new PG_foreign
page flag which with CONFIG_SPARSEMEM_MANUAL and CONFIG_HIGHMEM64G
enabled overflow page flags field which is - surprise - 32-bit long in
i386 (for more details read include/linux/page-flags.h file).
Solution:
- enable CONFIG_HIGHMEM4G,
- disable CONFIG_XEN (I am not sure that it
is good one for you :-))) ).
Daniel
