jfs: Several bugs in jfs_freeze() and jfs_unfreeze()
The mentioned functions do not pay attention to the error codes returned
by the functions updateSuper(), lmLogInit() and lmLogShutdown(). It brings
to system crash later when writing to log.
The patch adds corresponding code to check and return the error codes
and to print correct error messages in case of errors.

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

MIPS: N64: Wire getdents64(2)
As a relatively new ABI, N64 only had getdents syscall while other modern
architectures have getdents64.
This was noticed when Python 3.3 shifted to the latter one for aarch64.
[ralf@linux-mips.org: The history of getdents64 is a little complicated.
Commit
1a1d77dd589de5a567fa95e36aa6999c704ceca4 [Merge with 2.4.0-test7.]
added N64 getdents(2) to arch/mips64/kernel/scall_64.S as syscall 5213,
then dropped again in

MIPS: Idle: Break r4k_wait into two functions and fix it.
local_irq_enable() may expand into very different code, so it rather should
stay in C. Also this keeps the assembler code size constant which keeps
the rollback code simple. So it's best to split r4k_wait into two parts,
one C and one assembler.
Finally add the local_irq_enable() to r4k_wait to ensure the WAIT
instruction in __r4k_wait() will work properly.

leds: leds-gpio: reserve gpio before using it
This reverts commit
a99d76f (leds: leds-gpio: use gpio_request_one)
and commit
2d7c22f (leds: leds-gpio: set devm_gpio_request_one()
flags param correctly) which was a fix of the first one.
The conversion to devm_gpio_request in commit
e3b1d44c (leds:
leds-gpio: use devm_gpio_request_one) is not reverted.
The problem is that gpio_cansleep() and gpio_get_value_cansleep()
calls can crash if the gpio is not first reserved. Incidentally this
same bug existed earlier and was fixed similarly in commit
d95cbe61
(leds: Fix potential leds-gpio oops). But the OOPS is real. It happens
when GPIOs are provided by module which is not yet loaded.

tty/vt: Fix vc_deallocate() lock order
Now that the tty port owns the flip buffers and i/o is allowed
from the driver even when no tty is attached, the destruction
of the tty port (and the flip buffers) must ensure that no
outstanding work is pending.
Unfortunately, this creates a lock order problem with the
console_lock (see attached lockdep report [1] below).
For single console deallocation, drop the console_lock prior
to port destruction. When multiple console deallocation,
defer port destruction until the consoles have been
deallocated.
tty_port_destroy() is not required if the port has not
been used; remove from vc_allocate() failure path.

serial: 8250_dw: Add valid clk pointer check
Commit
ffc3ae6dd "serial: 8250_dw: Enable runtime PM" introduced runtime
PM management, which enables/disables the clk without checking if the clk
is valid. However, this driver allows to be probed without a defined clk,
using clock-frequency, as a fallback.
Therefore, on platforms that are device tree probed using clock-frequency
instead of clk, we get an ugly NULL pointer dereference.
This patch fixes it by simply adding a check before accessing the clk api.

However, the bit setting happens from secondary_startup_64(), which is

make: *** [vmlinux] Error 1
When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.
