[RESEND] [PATCH] alpha: remove dead BIO_VMERGE_BOUNDARY

[FUJITA Tomonori]

This is a resend of:

http://marc.info/?l=linux-kernel&m=122482703716610&w=2

Subject: [PATCH] alpha: remove dead BIO_VMERGE_BOUNDARY

The block layer dropped the virtual merge feature
(b8b3e16cfe6435d961f6aaebcfd52a1ff2a988c5). BIO_VMERGE_BOUNDARY
definition is meaningless now.
