vme_user: Enable compat_ioctl for mixed environment

2013-12-19T00:20:12+00:00

Now that the VME userspace API structures compile to a consistent size
in mixed environments (32-bit userspace and 64-bit kernel), enable the
.compat_ioctl to allow ioctls to execute in this environment.

vme_user: Update API to work in mixed environments

2013-12-18T01:06:19+00:00

This patch updates the vme_master and vme_slave structures to use
types with well defined size and to prevent the compiler from
inserting padding (between enable and vme_addr for one).

The original vme_master and vme_slave structs would be different
sizes and have different layouts depending on whether they were built
for a 32-bit or 64-bit system.

On x86 it is possible to have a 32-bit userspace and a 64-bit kernel.
In this type of environment, the userspace and kernel vme_user APIs
would disagree and prevent ioctls from executing (based on ioctl
signatures from _IOR and _IOW).

VME: Rename vme_slot_get to avoid confusion with reference counting

2013-12-03T19:15:58+00:00

Traditionally the "get" functions increment the reference count of the
object that is returned, which does not happen with vme_slot_get. The
function vme_slot_get returns the physical VME slot associated with a
particular struct vme_dev. Rename vme_slot_num to avoid any confusion.

VME: Provide access to VME bus enumeration and fix vme_user match function

2013-12-03T19:15:58+00:00

The match function for vme_user is completely wrong. It will blindly bind
against the first VME slot on each bus (at this point that would be just the
first bus as the driver can only handle one bus).

The original intention (before some major subsystem changes) was that the
driver bind against the slot to which the bridge was attached in the VME
system and to the bus(es) provided via the "bus" module parameter.

To do this cleanly (i.e. without poking arround in the subsystems internal
stuctures) a functionality has been added to provide access to the bus
enumeration.

staging: vme: fix error return code in vme_user_probe()

staging: vme: fix for a potential NULL pointer dereference

Audit the return value of cdev_alloc and hence fixes a potential NULL pointer
dereferencing.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2013-02-27T04:16:07+00:00

Pull vfs pile (part one) from Al Viro:
 "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
  locking violations, etc.

  The most visible changes here are death of FS_REVAL_DOT (replaced with
  "has ->d_weak_revalidate()") and a new helper getting from struct file
  to inode.  Some bits of preparation to xattr method interface changes.

  Misc patches by various people sent this cycle *and* ocfs2 fixes from
  several cycles ago that should've been upstream right then.

  PS: the next vfs pile will be xattr stuff."
