The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.I noticed two cases where config_enabled() is used against a tristate
option:- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.Link: http://lkml.kernel.org/r/1465215656-20569-1-git-send-email-yamada.masahiro@socionext.com

as one long-standing corner case issue (2.6.20, I think?) with
writing 1 byte less than a page.NOR:
- rework some error handling on reads and writes, so we can better
handle (for instance) SPI controllers which have limitations on
their maximum transfer size- add new Cadence Quad SPI flash controller driver
- add new Atmel QSPI flash controller driver
- add new Hisilicon SPI flash controller driver
- support a few new flash, and update supported features on others
- fix the logic used for detecting a fully-unlocked flash
And other miscellaneous small fixes"

...don't waste memory by allocating one sizeof(int) per
PEB.Signed-off-by: Richard Weinberger
-
Since PEB erasure is asynchornous it can happen that there is
more than one Fastmap on the MTD. This is fine because the attach logic
will pick the Fastmap data structure with the highest sequence number.On a not so well configured MTD stack spurious ECC errors are common.
Causes can be different, bad hardware, wrong operating modes, etc...
If the most current Fastmap renders bad due to ECC errors UBI might
pick an older Fastmap to attach from.
While this can only happen on an anyway broken setup it will show
completely different sympthoms and makes finding the root cause much
more difficult.
So, be debug friendly and fall back to scanning mode of we're facing
an ECC error while scanning for Fastmap.Cc:

When the volume resize operation shrinks a volume,
LEBs will be unmapped. Since unmapping will not erase these
LEBs immediately we have to wait for that operation to finish.
Otherwise in case of a power cut right after writing the new
volume table the UBI attach process can find more LEBs than the
volume table knows. This will render the UBI image unattachable.Fix this issue by waiting for erase to complete and write the new
volume table afterward.Cc:

When reading the vid hdr from the device UBI always reads a whole
page. Instead, read only the data we actually need and speed up
attachment of UBI devices by potentially making use of reading
subpages if the NAND driver supports it.Since the VID header may be at offset vid_hdr_shift in the page and
we can only read from the beginning of a page we have to add that
offset to the read size.Signed-off-by: Sascha Hauer

Pull block driver updates from Jens Axboe:
"This branch also contains core changes. I've come to the conclusion
that from 4.9 and forward, I'll be doing just a single branch. We
often have dependencies between core and drivers, and it's hard to
always split them up appropriately without pulling core into drivers
when that happens.That said, this contains:
- separate secure erase type for the core block layer, from
Christoph.- set of discard fixes, from Christoph.
- bio shrinking fixes from Christoph, as a followup up to the
op/flags change in the core branch.- map and append request fixes from Christoph.
- NVMeF (NVMe over Fabrics) code from Christoph. This is pretty
exciting!- nvme-loop fixes from Arnd.
- removal of ->driverfs_dev from Dan, after providing a
device_add_disk() helper.- bcache fixes from Bhaktipriya and Yijing.
- cdrom subchannel read fix from Vchannaiah.
- set of lightnvm updates from Wenwei, Matias, Johannes, and Javier.
- set of drbd updates and fixes from Fabian, Lars, and Philipp.
- mg_disk error path fix from Bart.
- user notification for failed device add for loop, from Minfei.
- NVMe in general:
+ NVMe delay quirk from Guilherme.
+ SR-IOV support and command retry limits from Keith.
+ fix for memory-less NUMA node from Masayoshi.
+ use UINT_MAX for discard sectors, from Minfei.
+ cancel IO fixes from Ming.
+ don't allocate unused major, from Neil.
+ error code fixup from Dan.
+ use constants for PSDT/FUSE from James.

====================
pull-request: wireless-drivers-next 2016-07-22I'm sick so I have to keep this short, but here's the last pull request
to net-next. This time there's a trivial conflict with mtd tree:http://lkml.kernel.org/g/20160720123133.44dab209@canb.auug.org.au
We concluded with Brian (CCed) that it's best that we ask Linus to fix
this. The patches have been in linux-next for a couple of days. This
time I haven't done any merge tests so I don't know if there are any
other conflicts etc.Please let me know if there are any problems.
wireless-drivers-next patches for 4.8
Major changes:
wl18xx
* add initial mesh support
bcma
* serial flash support on non-MIPS SoCs
ath10k
* enable support for QCA9888
* disable wake_tx_queue() mac80211 op for older devices to workaround
throughput regressionath9k
* implement temperature compensation support for AR9003+

This controller driver is used only on ARM but is mostly written
portably so it can build on other arch'es. Unfortunately, at least x86
doesn't provibe readsl()/writesl() accessors. We could possibly fix this
issue in the future by using io{read,write}32_rep() instead, but let's
just drop the architectures we aren't using for now.Signed-off-by: Brian Norris

nand_do_write_ops() determines if it is writing a partial page with the
formula:
part_pagewr = (column || writelen < (mtd->writesize - 1))When 'writelen' is exactly 1 byte less than the NAND page size the formula
equates to zero, so the code doesn't process it as a partial write,
although it should.
As a consequence the function remains in the while(1) loop with 'writelen'
becoming 0xffffffff and iterating endlessly.The bug may not be easy to reproduce in Linux since user space tools
usually force the padding or round-up the write size to a page-size
multiple.
This was discovered in U-Boot where the issue can be reproduced by
writing any size that is 1 byte less than a page-size multiple.
For example, on a NAND with 2K page (0x800):
=> nand erase.part
=> nand write $loadaddr 7ff[Editor's note: the bug was added in commit 29072b96078f, but moved
around in commit 66507c7bc8895 ("mtd: nand: Add support to use nand_base

We dropped strict MIPS dependency for bcm47xxsflash driver in:
commit 5651d6aaf489 ("mtd: bcm47xxsflash: use ioremap_cache() instead of
KSEG0ADDR()") but using ioremap_cache still limits building it to few
selected architectures only.A recent commit 57d8f7dd2132 ("bcma: allow enabling serial flash support
on non-MIPS SoCs") automatically dropped MIPS dependency for
MTD_BCM47XXSFLASH which broke building e.g. on powerpc and cris.The bcma change is alright as it doesn't break building bcma code in any
way. MTD_BCM47XXSFLASH on the other hand should be limited to archs
which need it and can build it (by providing ioremap_cache).Fixes: 57d8f7dd2132 ("bcma: allow enabling serial flash support on non-MIPS SoCs")

Change the BUG_ON() condition in brcmnand_send_cmd() which checks for
the interrupt status "controller ready" bit to a WARN_ON.There is no good reason to kill the system when this condition occur
because we could have systems which listed the NAND controller as
available (e.g: from Device Tree), but the NAND chip could be
malfunctioning and not responding.Signed-off-by: Florian Fainelli

There is a cut and paste issue here. The bug is that we are allocating
more memory than necessary for msp_maps. We should be allocating enough
space for a map_info struct (144 bytes) but we instead allocate enough
for an mtd_info struct (1840 bytes). It's a small waste.The other part of this is not harmful but when we allocated msp_flash
then we allocated enough space fro a map_info pointer instead of an
mtd_info pointer. But since pointers are the same size it works out
fine.Anyway, I decided to clean up all three allocations a bit to make them
a bit more consistent and clear.Fixes: 68aa0fa87f6d ('[MTD] PMC MSP71xx flash/rootfs mappings')

Gigadevice flash support BP{0,1,2,3,4} bits, where BP3 means the same as
the existing supported TB (Top/Bottom), and BP4 means the same as the
not-yet-supported 4K bit used on other flash (e.g., Winbond). Let's
support lock/unlock with the same feature flags as w25q32dw/w25q64dw.Tested on gd25lq64c, but I checked datasheets for the other 3, to make
sure.While I was at it, I noticed that these all support dual and quad as
well. I noted them, but can't test them at the moment, since my test
