Hi Vinod,

You may want to use the proper SPDX ids convention here instead? e.g.
below is all you need IMHO: not 50 lines of boilerplate but only two.

You will make everyone happier with a sigh of relief when you remove
this boilerplate, and you will also have saved a few trees if this
ever printed on paper, making earth a better planet as a bonus ;)

Neater and simpler, is it not? In any case the SPDX line should go at the top.
See Linus and tglx doc posts for comment and doc styles for this.
NB: some includes used in assembly sometimes require to use /**/
comments instead.
