Subject: RE: [PATCH] ARM: Use asm-generic/sizes.h

Firstly, the sizes.h is do derived from arm version.
And I just complete the SZ_* definitions for 32-bit architecture,
and remove SZ_48M for not being power-of-2 size.
I am sorry for removing copyright information when cleaning-up the code.
However, the content of this file is so common sense for handy sizes.
So, I believe that GPLv2 license is enough.

Regards.

Guan Xuetao
