Now that the of_node pointer is part of struct device,
of_device_get_modalias could be used on any struct device
that has the device node pointer set. This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.

Merge common irq mapping code between PowerPC and Microblaze.
This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one(). The functions are dependent on one another, so all
three are merged in a single patch. Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.
of_irq_to_resource() is also merged, but in this case the
implementations are different. This patch drops the microblaze version
and uses the powerpc implementation unchanged. The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do. Therefore the powerpc version is safe to adopt.

A message can be on a queue (pending or sent), or out_msg (sending), or

but that was false in the case of lossy connections like the OSD. Fix
ceph_con_revoke() to treat these cases independently. Also, fix the
out_kvec_is_message check to only trigger if we are currently sending

When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails,
because of following error message:
...

[ 0.424000] b44: Invalid MAC address found in EEPROM
[ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting
[ 0.436000] b44: probe of ssb0:1 failed with error -22
...
The router uses a CFE bootloader, but most of the needed environment
variables for network card initialization, are not available from CFE
via printenv and even though not via cfe_getenv().
The required environment variables are saved in a special partition
in flash memory. The attached patch implement nvram_getenv and enables
bootup via NFS root on my router.
Most of the patch is extracted from the OpenWrt subversion repository and
stripped down and cleaned up to just fix this issue.

With the help of uasm this patch encodes the instructions of the dynamic

As a result we can remove the dynamic encoding of instructions in
ftrace_make_nop()/call(), ftrace_enable_ftrace_graph_caller() and remove
the macro jump_insn_encode() and at last this reduce the overhead of
dynamic Function Tracer. This also is cleaner.

On 64-bit kernels $12 is t0 but in 32-bit kernels it is t4 so we need to
use $12 instead of t0 here to be correct for both kernel types.

When the PCI SSID gives an overriding SKU assno, PC-beep bit isn't
detected (since it's located over 16bit), resulting in no PC beep.
Also, many devices seem ignoring the requirement by Realtek's spec
for SSID numbers, and it also confuses the PC beep detection.
This patch assumes the PC beep is available on every machine with
PCI SSID override. It's a regression fix from 2.6.34.

Reimplement augmented RB-trees without sprinkling extra branches
all over the RB-tree code (which lives in the scheduler hot path).
This approach is 'borrowed' from Fabio's BFQ implementation and
relies on traversing the rebalance path after the RB-tree-op to
correct the heap property for insertion/removal and make up for
the damage done by the tree rotations.
For insertion the rebalance path is trivially that from the new
node upwards to the root, for removal it is that from the deepest
node in the path from the to be removed node that will still
be around after the removal.

1. Corrected shift values of I2S and UART clocks (CLK_GATE_IP3), which were
defined incorrectly.
2. Corrected shift values of sclk_audio, uclk1, sclk_fimd, sclk_mmc,
sclk_spi, sclk_pwm, which had duplicated .enable/.ctrlbit with their
twins defined in struct clk init_clocks_disable[] and struct clk
init_clocks[]. We've changed their .enable/.ctrlbit to use CLK_SRC_MASK
register to avoid the duplicated clock problem described below.
NOTE: Duplicated Clock Problem
Please note that each clock definition should access different control
register; otherwise, the system may suffer lockups. For example, if we
have two clock definitions "a" and "b" which access the same register
(and the shift value). Then, when we do:
module A
clk = clk_get("a");
clk->clk_enable(clk);
module B (context switch)
clk = clk_get("b");
clk->clk_enable(clk);
do something with clk.
clk->clk_disable(clk);
module A (context switch)
do something with clk
* At this point, the system may hang.
Therefore, there should be no clock definitions with the same contol
register/shift. If we need to create "aliases", then, creating child
clocks sharing the clock should be fine.
3. Corrected other sclk_* shift values and access registers.
