a115902f67 vt_ioctl: fix lock imbalance
Don't return from switch/case directly in vt_ioctl. Set ret and break
instead so that we unlock BKL.

56578abfd1 bfin_jtag_comm: clean up printk usage
The original patch garned some feedback and a v2 was posted, but that
version seems to have been missed when merging the driver.

At any rate, this cleans up the printk usage as suggested by Jiri Slaby.

a90b037583 char: moxa, prevent opening unavailable ports
In moxa.c there are 32 minor numbers reserved for each device.  The number
of ports actually available per device is stored in
moxa_board_conf->numPorts.  This number is not considered in moxa_open().
Opening a port that is not available results in a kernel oops.  This patch
adds a test to moxa_open() that prevents opening unavailable ports.

d6580a9f15 kexec: sysrq: simplify sysrq-c handler
Currently the sysrq-c handler is bit over-engineered.  Its behavior is
dependent on a few compile time and run time factors that alter its
behavior which is really unnecessecary.

If CONFIG_KEXEC is not configured, sysrq-c, crashes the system with a NULL
pointer dereference.  If CONFIG_KEXEC is configured, it calls crash_kexec
directly, which implies that the kexec kernel will either be booted (if
its been previously loaded), or it will simply do nothing (the no kexec
kernel has been loaded).

It would be much easier to just simplify the whole thing to dereference a
NULL pointer all the time regardless of configuration.  That way, it will
always try to crash the system, and if a kexec kernel has been loaded into
reserved space, it will still boot from the page fault trap handler
(assuming panic_on_oops is set appropriately).

81fc401e42 ppdev: reduce kernel log spam
One of my programs frequently grabs the parport, does something with it
and then drops it again. This results in spamming of the kernel log with

"... registered pardevice"
"... unregistered pardevice"

These messages are completely useless, except for debugging ppdev,
probably.  So put them under DEBUG (or dynamic debug).

e088a4ad7f [IA64] Convert ia64 to use int-ll64.h
It is generally agreed that it would be beneficial for u64 to be an
unsigned long long on all architectures.  ia64 (in common with several
other 64-bit architectures) currently uses unsigned long.  Migrating
piecemeal is too painful; this giant patch fixes all compilation warnings
and errors that come as a result of switching to use int-ll64.h.

Note that userspace will still see __u64 defined as unsigned long.  This
is important as it affects C++ name mangling.

[Updated by Tony Luck to change efi.h:efi_freemem_callback_t to use
 u64 for start/end rather than unsigned long]

f324edc85e console: make blank timeout value a boot option
The console blank timer is currently hardcoded to 10*60 seconds which
might be annoying on systems with no input devices attached to wake up the
console again.  Especially during development, disabling the screen saver
can be handy - for example when debugging the root fs mount mechanism or
other scenarios where no userspace program could be started to do that at
runtime from userspace.

This patch defines a core_param for the variable in charge which allows
users to entirely disable the blank feature at boot time by setting it 0.
The value can still be overwritten at runtime using the standard ioctl
call - this just allows to conditionally change the default.

1aa4bed82a tty: fix sanity check
The WARN_ON() that was added to tty_reopen can be triggered in the specific
case of a hangup occurring during a re-open of a tty which is not in the
middle of being otherwise closed.

In that case however the WARN() is bogus as we don't hold the neccessary
locks to make a correct decision.

The case we should be checking is "if the ldisc is not changing and reopen
is occuring". We could drop the WARN_ON but for the moment the debug is more
valuable even if it means taking a mutex as it will find any other cases.

cbcb6d66af pty: Narrow the race on ldisc locking
The pty code has always been buggy on its ldisc handling. The recent
changes made the window for the race much bigger. Pending fixing it
properly which is not at all trivial, at least make the race small again so
we don't disrupt other dev work.

0259162ecd [S390] pm: hvc_iucv power management callbacks
The patch adds supporting for suspending and resuming IUCV HVC terminal
devices from disk. The obligatory Linux device driver interfaces has
been added by registering a device driver on the IUCV bus.
For each IUCV HVC terminal device the driver creates a respective device
on the IUCV bus.

To support suspend and resume, the PM freeze callback severs any established
IUCV communication path and triggers a HVC tty hang-up when the system image
is restored.
IUCV communication path are no longer valid when the z/VM guest is halted.

The device driver initialization has been updated to register devices and
the a new routine has been extracted to facilitate the hang-up of IUCV HVC
terminal devices.

9de33df41f ipmi: remove driver_data direct access of struct device
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

6bd57f2e5d ps3flash: Cache the last accessed FLASH chunk
Add support for caching, to reduce FLASH wear when writing using small
blocksizes. As we also don't care anymore about heads and tails in case of
partial writes, this greatly simplifies the code for handling writes.

Note: We don't bother caching reads smaller than the FLASH chunk size
(256 KiB).
