When the CONFIG_STRICT_KERNEL_RWX is enabled for the armv7 kernel the
_stext is aligned to 1<<SECTION_SHIFT, which with hitherto code causes
wrong page_offset determination.
Suit mask used for page_offset in a way that it will allow to correctly
determine page_offset regardless of CONFIG_STRICT_KERNEL_RWX and
CONFIG_ARM_LPAE settings.
