In case of CONFIG_X86_64, vdso32/vclock_gettime.c fakes a 32-bit non-PAE kernel configuration by re-defining it to CONFIG_X86_32. However, it does not re-define CONFIG_PGTABLE_LEVELS leaving it as 4 levels. This mismatch leads <asm/pgtable_type.h> to NOT include <asm-generic/ pgtable-nopud.h> and <asm-generic/pgtable-nopmd.h>, which will cause compile errors when a later patch enhances <asm/pgtable_type.h> to use PUD_SHIFT and PMD_SHIFT. These -nopud & -nopmd headers define these SHIFTs for the 32-bit non-PAE kernel. Fix it by re-defining CONFIG_PGTABLE_LEVELS to 2 levels.
