dynamic_debug: Remove unnecessary __used

The __used attribute prevents gcc from eliminating
unnecessary, otherwise optimized away, metadata for
debugging logging messages.

Remove the __used attribute.

sysfs: sysfs_pathname/sysfs_add_one: Use strlcat() instead of strcat()

The warning check for duplicate sysfs entries can cause a buffer overflow
when printing the warning, as strcat() doesn't check buffer sizes.
Use strlcat() instead.

Since strlcat() doesn't return a pointer to the passed buffer, unlike
strcat(), I had to convert the nested concatenation in sysfs_add_one() to
an admittedly more obscure comma operator construct, to avoid emitting code
for the concatenation if CONFIG_BUG is disabled.

libceph: avoid NULL kref_put when osd reset races with alloc_msg

The ceph_on_in_msg_alloc() method drops con->mutex while it allocates a
message.  If that races with a timeout that resends a zillion messages and
resets the connection, and the ->alloc_msg() method returns a NULL message,
it will call ceph_msg_put(NULL) and BUG.

Fix by only calling put if msg is non-NULL.

staging: tidspbridge: request the right irq for mmu

Requested irq for mmu is currently conflicting with a DMA irq
due to recent changes to irq header files, now the offset for the
start of the interrupt controller numbering has changed.

This should be removed during a future migration to omap-iommu,
for now it is hardcoded.
