Commit 4316302292 ("mtd: m25p80: allow arbitrary OF matching for
"jedec,spi-nor"") moved the "jedec,spi-nor" handling from the
spi_device_id table to the of_match_table, to better handle matching
complex device tree compatible strings. With that patch, device tree
support works as expected when m25p80.c is built into the kernel.
However, that commit ignored the fact that:
(1) (non-DT) platform devices might want to use the "spi-nor" string
for matching with this driver, rather than picking an arbitrary one
like "m25p80"
(2) the core SPI uevent/modalias code doesn't yet support kernel module
autoloading via of_match_table strings; so for DT-based devices, it
will only report (part of) the first compatible string used
Problem (1) has been reported previously, and I forgot to patch it up
afterward.
Problem (2) was noticed recently here:
http://lists.infradead.org/pipermail/linux-mtd/2015-October/062369.htmlhttps://lkml.org/lkml/2015/11/12/574
Specifically, this patch fixes m25p80.ko module autoloading for cases
like this:
flash@xxx {
compatible = "jedec,spi-nor";
...
};
because modalias of "spi:spi-nor" (the only module loading info provided
by the SPI core for this device) will now be listed as an alias in
m25p80.ko.
Notably, it does *not* help cases like this:
flash@xxx {
compatible = "vendor,shiny-new-device", "jedec,spi-nor";
...
};
unless we also list "shiny-new-device" in m25p_ids[]. There has been
discussion on future work for this issue here:

The ->priv field of the mtd_info object attached to a nand_chip device
should point to the nand_chip device. The pxa and cafe drivers are
assigning this field their own private structure, which works fine as long
as the nand_chip field is the first one in the driver private struct but
seems a bit fragile.
Fix that by setting mtd->priv to point the nand_chip field and assigning
chip->priv to the private structure head.

The Data Flash Control Register (NDCR) contains two types
of parameters: those that are needed for device identification,
and those that can only be set after device identification.
Therefore, the driver can't set them all at once and instead
needs to configure the first group before nand_scan_ident()
and the second group later.
Let's split pxa3xx_nand_config in two halves, and set the
parameters that depend on the device geometry once this is known.

The chunk size represents the size of the data chunks, which
is used by the controllers that allow to split transfered data.
However, the initial chunk size is used in a non-splitted way,
during device identification. Therefore, it must be large enough
for all the NAND commands issued during device identification.
This includes NAND_CMD_PARAM which was recently changed to
transfer up to 2048 bytes (for the redundant parameter pages).
Thus, the initial chunk size should be 2048 as well.
On Armada 370/XP platforms (NFCv2) booted without the keep-config
devicetree property, this commit fixes a timeout on the NAND_CMD_PARAM

If multiple NAND chips are registered to the same controller, then when
rebooting the system, the first one will grab the controller lock, while
the second will wait forever for the first one to release it. i.e., a
classic deadlock.
This problem was solved for a similar case (suspend/resume) back in
commit 6b0d9a8412 ("mtd: nand: fix multi-chip suspend problem"), and
the shutdown state really isn't much different for us, so rather than
adding a new special case to nand_get_device(), we can just overload the
FL_PM_SUSPENDED state.
Now, multiple chips can "get" the same controller lock (preventing
further I/O), while we still allow other chips to pass through
nand_shutdown().

Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)
- So move mem_service exception handler from common code into ARCv2 code.
- In ARCompact code, define mem_service as L2 interrupt handler which
just drops down to pure kernel mode and goes of to enqueue SIGBUS

Pull chrome platform updates from Olof Johansson:
"Here's the branch of chrome platform changes for v4.4. Some have been
queued up for the full 4.3 release cycle since I forgot to send them
in for that round (rebased early on to deal with fixes conflicts).
Most of these enable EC communication stuff -- Pixel 2015 support,
enabling building for ARM64 platforms, and a few fixes for memory
leaks.
There's also a patch in here to allow reading/writing the verified
boot context, which depends on a sysfs patch acked by Greg"

Sorry for the delay in this patch which was mostly caused by getting the
merger of the mpt2/mpt3sas driver, which was seen as an essential item of
maintenance work to do before the drivers diverge too much. Unfortunately,
this caused a compile failure (detected by linux-next), which then had to be
fixed up and incubated. In addition to the mpt2/3sas rework, there are
updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc
and ufs plus an assortment of changes including some year 2038 issues, a fix
for a remove before detach issue in some drivers and a couple of other minor
issues.

Pull SCSI target updates from Nicholas Bellinger:
"This series contains HCH's changes to absorb configfs attribute
->show() + ->store() function pointer usage from it's original
tree-wide consumers, into common configfs code.
It includes usb-gadget, target w/ drivers, netconsole and ocfs2
changes to realize the improved simplicity, that now renders the
original include/target/configfs_macros.h CPP magic for fabric drivers
and others, unnecessary and obsolete.
And with common code in place, new configfs attributes can be added
easier than ever before.
Note, there are further improvements in-flight from other folks for
v4.5 code in configfs land, plus number of target fixes for post -rc1
code"
In the meantime, a new user of the now-removed old configfs API came in
through the char/misc tree in commit 7bd1d4093c ("stm class: Introduce
an abstraction for System Trace Module devices").
This merge resolution comes from Alexander Shishkin, who updated his stm
class tracing abstraction to account for the removal of the old
show_attribute and store_attribute methods in commit 517982229f
("configfs: remove old API") from this pull. As Alexander says about
that patch:
"There's no need to keep an extra wrapper structure per item and the
awkward show_attribute/store_attribute item ops are no longer needed.
This patch converts policy code to the new api, all the while making
the code quite a bit smaller and easier on the eyes.
Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>"
That patch was folded into the merge so that the tree should be fully
bisectable.

Now that the xattr handler is passed to the xattr handler operations, we
have access to the attribute name prefix, so simplify
f2fs_xattr_generic_list.
Also, f2fs_xattr_advise_list is only ever called for
f2fs_xattr_advise_handler; there is no need to double check for that.
