The patch 1da177e4c3: "Linux-2.6.12-rc2" from Apr 16, 2005
(linux-next), leads to the following Smatch static checker warning:
drivers/infiniband/hw/mthca/mthca_cmd.c:644 mthca_SYS_EN()
error: uninitialized symbol 'out'.
drivers/infiniband/hw/mthca/mthca_cmd.c
636 int mthca_SYS_EN(struct mthca_dev *dev)
637 {
638 u64 out;
639 int ret;
640
641 ret = mthca_cmd_imm(dev, 0, &out, 0, 0, CMD_SYS_EN, CMD_TIME_CLASS_D);
We pass out here and it gets used without being initialized.
err = mthca_cmd_post(dev, in_param,
out_param ? *out_param : 0,
^^^^^^^^^^
in_modifier, op_modifier,
op, context->token, 1);
It's the same in mthca_cmd_wait() and mthca_cmd_poll().

The queue index wrap around logic is based on power of 2 size depth.
All queues are created with power of 2 depth. This increases the
memory usage by the driver. This change is required for the next
patches that avoids the power of 2 depth requirement for each of
the queues.
Update the function that increments producer index and consumer
index during wrap around. Also, changes the index handling across
multiple functions.

Pull parisc architecture fixes from Helge Deller:
- Include the upper 5 address bits when inserting TLB entries on a
64-bit kernel.
On physical machines those are ignored, but in qemu it's nice to have
them included and to be correct.

a machine with a 32-bit CPU

Pull probes fixes from Masami Hiramatsu:
- Documentation update: Add a note about argument and return value
fetching is the best effort because it depends on the type.
- objpool: Fix to make internal global variables static in
test_objpool.c.
- kprobes: Unify kprobes_exceptions_nofify() prototypes. There are the
same prototypes in asm/kprobes.h for some architectures, but some of
them are missing the prototype and it causes a warning. So move the
prototype into linux/kprobes.h.
- tracing: Fix to check the tracepoint event and return event at
parsing stage. The tracepoint event doesn't support %return but if
$retval exists, it will be converted to %return silently. This finds
that case and rejects it.
- tracing: Fix the order of the descriptions about the parameters of
__kprobe_event_gen_cmd_start() to be consistent with the argument
list of the function.
