Pull IPMI updates from Corey Minyard:
 "Some small fixes for IPMI, and one medium sized changed.

  The medium sized change is adding a platform device for IPMI entries
  in the DMI table. Otherwise there is no auto loading for IPMI devices
  if they are only in the DMI table"

Merge branch 'misc.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2017-07-07T03:57:13+00:00

Pull misc compat stuff updates from Al Viro:
 "This part is basically untangling various compat stuff. Compat
  syscalls moved to their native counterparts, getting rid of quite a
  bit of double-copying and/or set_fs() uses. A lot of field-by-field
  copyin/copyout killed off.

   - kernel/compat.c is much closer to containing just the
     copyin/copyout of compat structs. Not all compat syscalls are gone
     from it yet, but it's getting there.

   - ipc/compat_mq.c killed off completely.

   - block/compat_ioctl.c cleaned up; floppy compat ioctls moved to
     drivers/block/floppy.c where they belong. Yes, there are several
     drivers that implement some of the same ioctls. Some are m68k and
     one is 32bit-only pmac. drivers/block/floppy.c is the only one in
     that bunch that can be built on biarch"

ipmi:ssif: Add missing unlock in error branch

2017-06-30T12:18:08+00:00

When getting flags, a response to a different message would
result in a deadlock because of a missing unlock.  Add that
unlock and a comment.  Found by static analysis.

sched/wait: Rename wait_queue_t => wait_queue_entry_t

2017-06-20T10:18:27+00:00

Rename:

	wait_queue_t		=>	wait_queue_entry_t

'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.

Start sorting this out by renaming it to 'wait_queue_entry_t'.

This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.

ipmi: Convert DMI handling over to a platform device

2017-06-19T17:49:38+00:00

Now that the IPMI DMI code creates a platform device for IPMI devices
in the firmware, use that instead of handling all the DMI work
in the IPMI drivers themselves.

ipmi: Create a platform device for a DMI-specified IPMI interface

2017-06-19T17:49:36+00:00

Create a platform device for each IPMI device in the DMI table,
a separate kind of device for SSIF types and for KCS, BT, and
SMIC types.  This is so auto-loading IPMI devices will work
from just SMBIOS tables.

This also adds the ability to extract the slave address from
the SMBIOS tables, so that when the driver uses ACPI-specified
interfaces, it can still extract the slave address from SMBIOS.
