Hello. I'm try to compile 32 bit pae kernel from xen git repo. If i
check sparse memory - i get error 
scripts/kconfig/conf -s arch/x86/Kconfig
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  SYMLINK include/asm -> include/asm-x86
  CC      kernel/bounds.s
  GEN     include/linux/bounds.h
  CC      arch/x86/kernel/asm-offsets.s
In file included from include/linux/suspend.h:8,
                 from arch/x86/kernel/asm-offsets_32.c:11,
                 from arch/x86/kernel/asm-offsets.c:2:
include/linux/mm.h:518:2: error: #error SECTIONS_WIDTH+NODES_WIDTH
+ZONES_WIDTH > BITS_PER_LONG - NR_PAGEFLAGS
make[1]: *** [arch/x86/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2


But if a check flat memory - compiling fine, but a can't get memory
hotplug, does memory hotplug possible with flat memory ? Or only with
sparse?

Daniel, can You check this?
