Staging: rtl8192e: mark symbols static where possible
We get a few warnings when building kernel with W=1:
drivers/staging/rtl8192e/rtllib_softmac.c:279:13: warning: no previous declaration for 'softmac_ps_mgmt_xmit' [-Wmissing-declarations]
drivers/staging/rtl8192e/rtllib_softmac.c:773:24: warning: no previous declaration for 'rtllib_authentication_req' [-Wmissing-declarations]
....
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
In addition, some of these functions are declared in different files,
it looks like that we need to clean the codes of this driver up,
but we can repress these warnings first, then clean it up.
so this patch marks these functions with 'static' now.

staging: rtl8192u: do not use undefined $(TOPDIR) in Makefile
drivers/staging/rtl8192u/ieee80211/Makefile uses $(TOPDIR) to configure
an include directory, without defining this variable first. The path
which is configured is therefore "/drivers/net/wireless", which does not
seem to be the intended path.
Remove the offending line.

Devicetree is the preferred mechanism for platform definition
these days. Add a set of files for supporting Ion with devicetree.
This includes a set of bindings for heaps common across all
devices and parsing methods. Clients may use the standard
bindings or they can call the parsing functions along with
their own parsing for platform specific heaps.

Ion clients currently lack a good method to determine what

For structure types defined in the same file or local header files, find
top-level static structure declarations that have the following
properties:
1. Never reassigned.
2. Address never taken
3. Not passed to a top-level macro call
4. No pointer or array-typed field passed to a function or stored in a

Declare structures having all of these properties as const.

On failure we were jumping to error_out0 where we were trying
sdio_release_host() but at this point of execution we still have not
done sdio_claim_host() and as a result host->claimed can still be 0.
And if host->claimed is 0 then WARN_ON(!host->claimed) will give
a warning.
Moreover, if it is still not claimed then mmc_host->claim_cnt will be 0
and mmc_release_host() will do "if (--host->claim_cnt)" and thus the
condition will become true.
Lets just return the value on allocation failure instead of trying to
release the host before claiming it.

Commit aa71987472a9 ("nvme: fabrics drivers don't need the nvme-pci

depend on the block layer (which used to be an implicit dependency
through BLK_DEV_NVME).
Otherwise you get various errors from the kbuild test robot random

"nvdimm fixes for v4.8, two of them are tagged for -stable:
- Fix devm_memremap_pages() to use track_pfn_insert(). Otherwise,
DAX pmd mappings end up with an uncached pgprot, and unusable
performance for the device-dax interface. The device-dax interface
appeared in 4.7 so this is tagged for -stable.
- Fix a couple VM_BUG_ON() checks in the show_smaps() path to
understand DAX pmd entries. This fix is tagged for -stable.
- Fix a mis-merge of the nfit machine-check handler to flip the
polarity of an if() to match the final version of the patch that
Vishal sent for 4.8-rc1. Without this the nfit machine check
handler never detects / inserts new 'badblocks' entries which
applications use to identify lost portions of files.
- For test purposes, fix the nvdimm_clear_poison() path to operate on
legacy / simulated nvdimm memory ranges. Without this fix a test
can set badblocks, but never clear them on these ranges.
- Fix the range checking done by dax_dev_pmd_fault(). This is not
tagged for -stable since this problem is mitigated by specifying
aligned resources at device-dax setup time.
These patches have appeared in a next release over the past week. The
recent rebase you can see in the timestamps was to drop an invalid fix
as identified by the updated device-dax unit tests [1]. The -mm
touches have an ack from Andrew"

fscrypto: require write access to mount to set encryption policy
Since setting an encryption policy requires writing metadata to the
filesystem, it should be guarded by mnt_want_write/mnt_drop_write.
Otherwise, a user could cause a write to a frozen or readonly
filesystem. This was handled correctly by f2fs but not by ext4. Make
fscrypt_process_policy() handle it rather than relying on the filesystem
to get it right.
