Fixes kernel BUG at lib/radix-tree.c:473.
Previously the handler was incidentally provided by tmpfs but this was
removed with:

tmpfs: fix kernel BUG in shmem_delete_inode
relying on this behaviour was incorrect in any case and the BUG also
appeared when the device node was on an ext3 filesystem.
v2: override a_ops at open() time rather than mmap() time to minimise
races per AKPM's concerns.

On a PowerPC board with ds1374 RTC I'm getting this error while RTC tries
to probe:
rtc-ds1374 0-0068: unable to request IRQ
This happens because I2C probing code (drivers/of/of_i2c.c) is specifying
IRQ0 for 'no irq' case, which is correct.
The driver handles this incorrectly, though. This patch fixes it.

With commit 5ad31a5751 ("rtc: remove BKL
for ioctl()"), RTC_UIE_ON ioctl cause double lock on rtc->ops_lock.
The ops_lock must not be held while set_uie() calls rtc_read_time()
which takes the lock. Also clear_uie() does not need ops_lock. This
patch fixes return value of RTC_UIE_OFF ioctl too.

Recent of_platform changes made of_bus_type_init() overwrite the bus
type's .dev_attrs list, meaning that the "name" attribute that ibmebus
devices previously had is no longer present. This is a user-visible
regression which breaks the userspace eHCA support, since the eHCA
userspace driver relies on the name attribute to check for valid
adapters.
This fixes it by providing the "name" attribute in the generic OF
device code instead. Tested on POWER.

sbp2 was too quick to report .update() to the ieee1394 core as failed.
(Logged as "Failed to reconnect to sbp2 device!".) The core would then
unbind sbp2 from the device.
This is not justified if the .update() failed because another bus reset
happened. We check this and tell the ieee1394 that .update() succeeded,
and the core will call sbp2's .update() for the new bus reset as well.
This improves reconnection/re-login especially on buses with several
disks as they may issue bus resets in close succession when they come
online.

Regression since commit 73cf60232e,
"ieee1394: use class iteration api": The two loops for (1.) driver
updates and (2.) driver probes were replaced by a single loop with
bogus needs_probe checks. Hence updates and probes were now intermixed,
and especially sbp2 updates (reconnects) held up longer than necessary.
While we fix it, change the needs_probe flag to bool type for clarity.

This patch should fix TOC handling for cdroms that can not play audio. It
extends commit af744e3294 ("cdrom: don't
check CDC_PLAY_AUDIO in cdrom_count_tracks()") with a safety check and
non-audio ioctls support.
Since CDC_PLAY_AUDIO flag was used not only to check ability to play audio
but also to ensure that audio_ioctl was not NULL, all TOC-related
operations had to use it.
As far as I understand, now audio_ioctl is never NULL, so a sanity check
during device registration should be sufficient.
It was tested on Optiarc AD7203A device, that has no ability to play
audio.

Otherwise we either end up with 16 bytes less on every requeue,
