If, in em28xx_usb_probe() the memory allocation
dev->alt_max_pkt_size = kmalloc(32*
dev->num_alt,GFP_KERNEL);
fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated
to 'dev', thus causing a memory leak.
This patch fixes the leak by freeing 'dev' before we return -ENOMEM.

The attached (mostly trivial) patches adds support for the Evolution
Scorpion Robots.
Evolution Robotics supplies a patch against 2.6.8 with their
software. My patch is based on their work, so I don't know if I can
sign it off, or if you need some Evolution people to do this (which
might be hard).
The patch adds device ID's for some robots which is trivial.

This patch contains two fixes submitted by Ondrej Palkovsky:
- the 'ACK' packet is sent after the transfer of the USB packet is
completed, i.e. in the write_callback function. Because the close
function sends the 'abort' command, a parameter is added that allows
the caller of garmin_write_bulk to specify, if the 'ack' should be
propagated to the serial link or dimissed.
This fixes the problem with gpsbabel, it has sent several packets that
were acknowledged before they were sent to the GPS and GpsBabel closed
the device - thus effectively cancelled all outstanding requests in the
queue.
- removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed
them into counters. It evades USB reset of the gps on every device close.

This patch (as950) fixes a bug in the cdc-acm driver. It doesn't keep
track of which interface (control or data) the sysfs attributes get

left-over attributes can cause a crash later on, particularly if the driver

Placing a kprobe on "bc" instruction (s390/s390x) can cause an oops.
The instruction length is encoded into the first two bits of the s390
instruction. Kprobe is incorrectly computing the instruction length.
The instruction length is used for determining what type of "fix-up" is
needed for conditional branch instruction. The problem can bee seen by
placing a kprobe on a "bc" instruction that will not branch. The
results is that Kprobe incorrectly computes the new instruction
pointer (psw.addr) after single stepping the instruction. The problem
is corrected with this patch.

the buffer state change may happen delayed. The tasklet for checking
changes in the outbound queue excluded IQDIO async queues from this

This patch uses kzalloc to zero all of struct dio rather than manually
trying to track which fields we rely on being zero. It passed aio+dio
stress testing and some bug regression testing on ext3.
This patch was introduced by Linus in the conversation that lead up to
Badari's minimal fix to manually zero .map_bh.b_state in commit:
6a648fa721
It makes the code a bit smaller. Maybe a couple fewer cachelines to
load, if we're lucky:
text data bss dec hex filename
3285925 568506 1304616 5159047 4eb887 vmlinux
3285797 568506 1304616 5158919 4eb807 vmlinux.patched
I was unable to measure a stable difference in the number of cpu cycles
spent in blockdev_direct_IO() when pushing aio+dio 256K reads at
~340MB/s.
So the resulting intent of the patch isn't a performance gain but to
avoid exposing ourselves to the risk of finding another field like
.map_bh.b_state where we rely on zeroing but don't enforce it in the
code.
