This just reworks the existing create_irq_on_node() in to the new
create_irq_nr() which is generally exposed. This permits boards that
haven't converted over to sparseirq to try and use their existing ranges,
rather than having arbitrary vectors assigned to them.

This patch improves disable_controller() in the r8a66597-hdc
driver to disable all interrupts and clear status flags. It
also makes sure that disable_controller() is called during
probe(). This fixes the relatively rare case of unexpected
pending interrupts after kexec reboot.

The spi_sh_msiof.c driver presently misconfigures REDG and TEDG. TEDG==0
outputs data at the **rising edge** of the clock and REDG==0 samples data
at the **falling edge** of the clock. Therefore for SPI, TEDG must be
equal to REDG, otherwise the last byte received is not sampled in SPI
mode 3.
This brings the driver in line with the SH7723 HW Reference Manual
settings documented in Figures 20.20 and 20.21 ("SPI Clock and data
timing").

In the transmit path of firewire-net (IPv4 over 1394), the following
race condition may occur:
- The networking soft IRQ inserts a datagram into the 1394 async
request transmit DMA.
- The 1394 async transmit completion tasklet runs to finish cleaning
up (unlink datagram from list of pending ones, release skb and
outbound 1394 transaction object) --- before the networking soft IRQ
had a chance to proceed and add the datagram to the list of pending
datagrams.
This caused a panic in the 1394 async transmit completion tasklet when
it dereferenced unitialized list heads:
http://bugzilla.kernel.org/show_bug.cgi?id=15077
The fix is to add checks in the tx soft IRQ and in the tasklet to
determine which of these two is the last referrer to the transaction
object. Then handle the cleanup of the object by the last referrer
rather than assuming that the tasklet is always the last one.
There is another similar race: Between said tasklet and fwnet_close,
i.e. at ifdown. However, that race is much less likely to occur in
practice and shall be fixed in a separate update.

Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access
to common->bus_ops, which is already freed as part of the device data.
Remove the cleanup field in struct ath_bus_ops, as it was never used
properly. Remove ath_bus_cleanup(). Merge cleanup functions in place
of the ath_bus_cleanup() calls. Take care not to use any device data

No other driver does anything remotely like this that I know of except
for the tty drivers, and I can't see any reason for random/urandom to do
it. In fact, it's a (trivial, harmless) timing information leak. And
obviously, it generates power- and flash-cycle wasting I/O, especially
if combined with something like hwrngd. Also, it breaks ubifs's
expectations.

UBI debugging functions were a little bit over-engineered and
returned more error codes than needed, and the callers had to
do useless checks. Simplify the return codes.
Impact: only debugging code is affected, which means that for
non-developers this is a no-op patch.

In the error path of 'ubi_attach_mtd_dev()' we have a tricky situation:
we have to release things differently depending on at which point
the failure happening. Namely, if @ubi->dev is not initialized, we have
to free everything ourselves. But if it was, we should not free the @ubi
object, because it will be freed in the 'dev_release()' function. And
we did not get this situation right.
This patch introduces additional argument to the 'uif_init()' function.
On exit, this argument indicates whether the final 'free(ubi)' will
happen in 'dev_release()' or not. So the caller always knows how to
properly release the resources.
Impact: all memory is now correctly released when UBI fails to attach
an MTD device.

The @mtd_devs and @mtd_dev_param variables are used only during the
initialization, and all functions that use the variables have
the __init prefix. This means we can safely mark the variables
as __initdata, which is a tiny optimization.
Impact: tiny RAM consumption optimization when UBI is used as a kernel
module.
