8bae0ff259 IB/ipath: Fix error recovery for send buffer status after chip freeze mode
The error recovery code for updating the driver's cached status information
for which send buffers are busy or free wasn't updated for IBA7220.
It should be similar to the initialization code in enable_chip().

c263ff65d5 IB/mthca: Avoid integer overflow when allocating huge ICM table
In mthca_alloc_icm_table(), the number of entries to allocate for the
table->icm array is computed by calculating obj_size * nobj and then
dividing by MTHCA_TABLE_CHUNK_SIZE.  If nobj is really large, then
obj_size * nobj may overflow and the division may get the wrong value
(even a negative value).  Fix this by calculating the number of
objects per chunk and then dividing nobj by this value instead.

This patch allows crazy configurations such as loading ib_mthca with
the module parameter num_mtt=33554432 to work properly.

19773539d6 IB/mthca: Avoid integer overflow when dealing with profile size
mthca_make_profile() returns the size in bytes of the HCA context
layout it creates, or a negative value if an error occurs.  However,
the return value is declared as u64 and the memfree initialization
path casts this value to int to test if it is negative.  This makes it
think incorrectly than an error has occurred if the context size
happens to be bigger than 2GB, since this turns into a negative int.

Fix this by having mthca_make_profile() return an s64 and testing
for an error by checking whether this 64-bit value itself is negative.

f4f82994d1 IB/ehca: Remove tgid checking
Pavel Emelyanov <xemul@openvz.org> mentioned in <http://lkml.org/lkml/2008/3/17/131>
that the task_struct->tgid field is about to become deprecated, so the
uses in the ehca driver need to be fixed up.

However, all the uses in ehca are for some object ownership checking
that is not really needed, and anyway is implementing a policy that
should be in common code rather than a low-level driver.  So just
remove all the checks.

1e89a1946c IB/srp: Enforce protocol limit on srp_sg_tablesize
The current SRP initiator will allow unlimited s/g entries in the
indirect descriptors lists, but the entry count field in the SRP_CMD
request is 8 bits, so setting srp_sg_tablesize too large will open the
possibility of wrapping the count and generating invalid requests.

Clamp srp_sg_tablesize to the protocol limits to prevent surprises.

37608eea86 mlx4_core: Fix confusion between mlx4_event and mlx4_dev_event enums
The struct mlx4_interface.event() method was supposed to get an enum
mlx4_dev_event, but the driver code was actually passing in the
hardware enum mlx4_event values.  Fix up the callers of
mlx4_dispatch_event() so that they pass in the right type of value,
and fix up the event method in mlx4_ib so that it can handle the enum
mlx4_dev_event values.

This eliminates the need for the subtype parameter to the event
method, so remove it.

07c3b1a100 USB: remove broken usb-serial num_endpoints check
The num_interrupt_in, num_bulk_in, and other checks in the usb-serial
code are just wrong, there are too many different devices out there with
different numbers of endpoints.  We need to just be sticking with the
device ids instead of trying to catch this kind of thing.  It broke too
many different devices.

This fixes a large number of usb-serial devices to get them working
properly again.
