Re: [PATCH trivial] include/asm-generic/pgtable.h: Notice about coding styles

[Chen Gang]

Hello all:

After communicated with my company, I am permitted to use my company
email to send patches to open source community.

My company supports what I have done for open source community, but at
present, I still use my personal mail id as Signed-of-by (make and send
patches mainly during my free time).

And thank my company for the support. 


Thanks.
