Mike Frysinger 140fab14ae blackfin RTC driver: wait for the write complete interrupt complete before sleeping
Since we use the write complete interrupt, wait for it
to complete before sleeping so we don't wake right back up due to it

David Brownell c69ad71bcd genirq: better warning on irqchip->set_type() failure
While I'm glad to finally see the hole fixed whereby passing an invalid
IRQ trigger type to request_irq() would be ignored, the current diagnostic
isn't quite useful.  Fixed by also listing the trigger type which was
rejected.

Tom Zanussi 3219445033 relay: fix "full buffer with exactly full last subbuffer" accounting problem
In relay's current read implementation, if the buffer is completely full
but hasn't triggered the buffer-full condition (i.e. the last write
didn't cross the subbuffer boundary) and the last subbuffer is exactly
full, the subbuffer accounting code erroneously finds nothing available.
This patch fixes the problem.

Bernhard Walle c6e2bee26e kdump: report actual value of VMCOREINFO_OSRELEASE in VMCOREINFO
The current implementation reports the structure name as
VMCOREINFO_OSRELEASE in VMCOREINFO, e.g.

        VMCOREINFO_OSRELEASE=init_uts_ns.name.release

That doesn't make sense because it's always the same. Instead, use the
value, e.g.

        VMCOREINFO_OSRELEASE=2.6.26-rc3

That's also what the 'makedumpfile -g' does.

Alan Stern 580da34847 Fix USB storage hang on command abort
Okay, I found the cause of the hang.  It is a simple bug in the USB
scatter-gather library, caused by changes added in response to the S-G
chaining modification.

This patch (as1125) fixes a bug in the USB scatter-gather library.
Early exit from the S-G initialization loop does not reset the count of
outstanding URBs.

Tejun Heo af744e3294 cdrom: don't check CDC_PLAY_AUDIO in cdrom_count_tracks()
According to MMC-3 (or any later versions) READ TOCs are mandatory
commands and have nothing to do with CDC_PLAY_AUDIO.  I have no idea why
the check was put there in the first place but it now only breaks
automatic actions on certain drives.

Note that this test was only effective when ide-cdrom was being used
as sr didn't mask CDC_PLAY_AUDIO according to the capabilities.

Petr Tesarik 938bb03d18 ide-cd: fix endianity for the error message in cdrom_read_capacity
Aesthetic regards aside, commit e8e7b9eb11
still leaves a bug in the error message, because it uses the unconverted
big-endian value for printk.

Fix this by using a local variable in machine byte order. The result is
correct, more readable, and also produces slightly shorter code on i386.

The guilty commit turned out to be 08da591e14
("ide: add ide_device_{get,put}() helpers").  ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.

Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.

v2:
Brown paper bag time.  In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski).  Fix it by caching cd->drive in
the local variable (fix other device drivers too).
