Drivers that register a ->fault handler, but do not range-check the
offset argument, must set VM_DONTEXPAND in the vm_flags in order to
prevent an expanding mremap from overflowing the resource.
I've audited the tree and attempted to fix these problems (usually by
adding VM_DONTEXPAND where it is not obvious).

This patch decreases the snd_pcm_hardware->period_bytes_min field in the
caiaq/usb audio driver. The hardware can actually handle as few as 128
bytes, depending on the system. So it makes no sense to keep
applications from actually using such values.

This header file exists only for some hacks to adapt alsa-driver
tree. It's useless for building in the kernel. Let's move a few
lines in it to sound/core.h and remove it.
With this patch, sound/driver.h isn't removed but has just a single
compile warning to include it. This should be really killed in
future.

another instance
- it is preferred for drivers to properly set up input_dev->phys to
help userspace locate devices
- drivers should use usb_to_input_id(), or perform endianess conversion,
themselves, otherwise ID is not correct on big-endian boxes

When CME keyboards send a SysEx message (e.g. master volume), the USB

and can cause the following MIDI messages to be misinterpreted, too.

The firmware of the M-Audio USB Uno MIDI Interface has, at least in
hardware revision 1.25, a bug that garbles its USB output. When it
receives a Note On MIDI message that uses running status, the resulting
USB MIDI packet has a wrong CIN (4 instead of 9) and a wrong length
(2 bytes, the status byte is still missing).
This patch adds a workaround to track the CINs and the MIDI messages of
received USB MIDI packets to detect whether a packet with CIN 4 is a
correct SysEx packet or a buggy running status packet.
