[PATCH v2 0/3] A trio of vchiq bulk transfer fixes

The recent batch of vchiq improvements broke bulk transfers in two ways:

1. The userdata associated with a transfer was lost in the case that a
   non-blocking mode was used.

2. The 64-bit ioctl compatibility shim for a bulk transfer used the
   wrong ioctl command.

This patch set fixes both of those bugs, and adds a security-related
note to the TODO file.

Changes in v2:
- Expand the commit message on patch 1 to clarify the impact of the
  bug, and add Tested-by.
- Add commit 3 with an additional TODO item.
- Change the name of the patch set to be numerically accurate.
