[PATCH] makedumpfile/arm: fix page_offset determination

[HAGIO KAZUHITO(萩尾 一仁)]

-----Original Message-----
> 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.
