If we don't check the current backing device status, balance_dirty_pages can
fall into infinite pausing routine.
This can be occurred when a lot of directories make a small number of dirty
dentry pages including files.
Reported-by: Brian Chadwick <brianchad@westnet.com.au>

If an inode is renamed, it should be registered as file_lost_pino to conduct
checkpoint at f2fs_sync_file.
Otherwise, the inode cannot be recovered due to no dent_mark in the following
scenario.
Note that, this scenario is from xfstests/322.
1. create "a"
2. fsync "a"
3. rename "a" to "b"
4. fsync "b"
5. Sudden power-cut
After recovery is done, "b" should be seen.
However, the result shows "a", since the recovery procedure does not enter
recover_dentry due to no dent_mark.
The reason is like below.
- The nid of "a" is checkpointed during #2, f2fs_sync_file.
- The inode page for "b" produced by #3 is written without dent_mark by
sync_node_pages.
So, this patch fixes this bug by assinging file_lost_pino to the "a"'s inode.
If the pino is lost, f2fs_sync_file conducts checkpoint, and then recovers
the latest pino and its dentry information for further recovery.

We should release the dentry block in init_inode_metadata to avoid this BUG_ON,

This patch fixes the dma state machine lockup due to the processing
of IDENTIFY DEVICE PIO mode command. The X-Gene AHCI controller
has an errata in which it cannot clear the BSY bit after the PIO setup
FIS. The dma state machine enters CMFatalErrorUpdate state and locks
up. This patch also removes the dma restart workaround from the read_id
function as the read_id function is only called by libata layer for
ATA_INTERNAL commands. But for some cases eg: PORT MULTIPLIER
and udev, the framework will enumerate using SCSI commands and it will
not call read_id function.

It is customary to clamp limits instead of bailing out with an error
if a configured limit is out of the range supported by the driver.
This simplifies limit configuration, since the user will not typically

In my investigation, I found the root cause is wq_numa_possible_cpumask.
All entries of wq_numa_possible_cpumask is allocated by
alloc_cpumask_var_node(). And these entries are used without initializing.
So these entries have wrong value.
When hot-adding and onlining CPU, wq_update_unbound_numa() is called.
wq_update_unbound_numa() calls alloc_unbound_pwq(). And alloc_unbound_pwq()
calls get_unbound_pool(). In get_unbound_pool(), worker_pool->node is set
as follow:
3592 /* if cpumask is contained inside a NUMA node, we belong to that node */
3593 if (wq_numa_enabled) {
3594 for_each_node(node) {
3595 if (cpumask_subset(pool->attrs->cpumask,
3596 wq_numa_possible_cpumask[node])) {
3597 pool->node = node;
3598 break;
3599 }
3600 }
3601 }
But wq_numa_possible_cpumask[node] does not have correct cpumask. So, wrong
node is selected. As a result, kernel panic occurs.
By this patch, all entries of wq_numa_possible_cpumask are allocated by
zalloc_cpumask_var_node to initialize them. And the panic disappeared.

Fixes: bce903809a ("workqueue: add wq_numa_tbl_len and wq_numa_possible_cpumask[]")
Upper limit for write operations to temperature limit registers
was clamped to a fractional value. However, limit registers do
not support fractional values. As a result, upper limits of 127.5
degrees C or higher resulted in a rounded limit of 128 degrees C.
Since limit registers are signed, this was stored as -128 degrees C.
Clamp limits to (-55, +127) degrees C to solve the problem.
Value on writes to auto_temp[12]_min and auto_temp[12]_max were not
clamped at all, but masked. As a result, out-of-range writes resulted
in a more or less arbitrary limit. Clamp those attributes to (0, 127)
degrees C for more predictable results.

"This is a set of 13 fixes, a MAINTAINERS update and a sparse update.
The fixes are mostly correct value initialisations, avoiding NULL
derefs and some uninitialised pointer avoidance.
All the patches have been incubated in -next for a few days. The
final patch (use the scsi data buffer length to extract transfer size)
has been rebased to add a cc to stable, but only the commit message
has changed"

This week's arm-soc fixes:
- A set of of OMAP patches that we had missed Tony's pull request of:
- Reset fix for am43xx
- Proper OPP table for omap5
- Fix for SoC detection of one of the DRA7 SoCs
- hwmod updates to get SATA and OCP to work on omap5 (drivers merged in 3.16)
- ... plus a handful of smaller fixes
- sunxi needed to re-add machine specific restart code that was removed in
anticipation of a watchdog driver being merged for 3.16, and it didn't make
it in.
- Marvell fixes for PCIe on SMP and a big-endian fix.
- A trivial defconfig update to make my capri test board boot with
bcm_defconfig again.
... and a couple of MAINTAINERS updates, one to claim new Keystone
drivers that have been merged, and one to merge MXS and i.MX (both
Freescale platforms).
The largest diffs come from the hwmod code for omap5 and the re-add of
the restart code on sunxi. The hwmod stuff is quite late at this point
but it slipped through cracks repeatedly while coming up the maintainer
chain and only affects the one SoC so risk is low.

This partly reverts commits 553600502b (ARM: sunxi: Remove reset code from
the platform) and 5e669ec583 (ARM: sunxi: Remove init_machine callback) for
the sun4i, sun5i and sun7i families.
This is needed because the watchdog counterpart of these commits was dropped,
and didn't make it into 3.16. In order to still be able to reboot the board, we
need to reintroduce that code. Of course, the long term view is still to get
rid of that code in mach-sunxi.

- Fix CPU OPP table for omap5
- Fix legacy mux parser bug if requested muxname is a prefix of
multiple mux entries
- Fix qspi interrupt binding that relies on the irq crossbar

- Drop unused gic_init_irq() that is no longer needed
And the enabling of features that had driver dependencies are:

clock now that the clock driver for it has been merged
- Enable off idle configuration for selected omaps as all the kernel
dependencies for device tree based booting are finally merged as
this is needed to get the automated PM tests working finally with

- Add hwmod entry for ocp2scp3 for omap5 to get sata working as

The CurrentEL system register reports the Current Exception Level
of the CPU. It doesn't say anything about the stack handling, and
yet we compare it to PSR_MODE_EL2t and PSR_MODE_EL2h.
It works by chance because PSR_MODE_EL2t happens to match the right
bits, but that's otherwise a very bad idea. Just check for the EL
value instead.
