Staging: vme: remove an unnecessary and wrong warning message

staging: vme_user: allow large read()/write()

2015-07-15T05:50:15+00:00

This changes large master transfers to do shorter read/write rather than return -EINVAL. User space will now be able to optimistically request a large transfer and get at least some data. This also removes comments suggesting on how to implement large transfers. Current vme_master_* read and write implementations use CPU copies that don't produce burst PCI accesses and subsequently no block transfer on VME bus. In the end overall performance is quiet low and it can't be fixed by doing direct copy to user space. Much easier solution would be to just reuse kernel buffer.
