x86/vdso32: Define PGTABLE_LEVELS to 32bit VDSO
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.
