Hello Haiyang,

Thank you for feedback.

[...]

The second line should be aligned next to the "(" on the first line.
Also the first line is now over 80 chars.

Sorry about this.  I will fix it in v3.  Thank you for pointing this 
out.

To address both the alignment and line length of 
hv_register_block_invalidate(),
I took a hint from the way how hv_compose_msi_req_v1() is current 
formatted.  I
hope that this would be acceptable.
