d6b9aea67f MAINTAINERS: Add documentation and dt-bindings for exynos stuff
Extend the Samsung Exynos maintainer entry to match SoC documentation
and SoC dt-bindings directories. Without that some files, like
bindings/arm/samsung/pmu.txt, are not matched by existing patterns.

This also may serve as a hint where new documentation and bindings
(not matching specific subsystem) should be put.

9767feb2c6 nfsd: ensure that seqid morphing operations are atomic wrt to copies
Bruce points out that the increment of the seqid in stateids is not
serialized in any way, so it's possible for racing calls to bump it
twice and end up sending the same stateid. While we don't have any
reports of this problem it _is_ theoretically possible, and could lead
to spurious state recovery by the client.

In the current code, update_stateid is always followed by a memcpy of
that stateid, so we can combine the two operations. For better
atomicity, we add a spinlock to the nfs4_stid and hold that when bumping
the seqid and copying the stateid.

cc8a55320b nfsd: serialize layout stateid morphing operations
In order to allow the client to make a sane determination of what
happened with racing LAYOUTGET/LAYOUTRETURN/CB_LAYOUTRECALL calls, we
must ensure that the seqids return accurately represent the order of
operations. The simplest way to do that is to ensure that operations on
a single stateid are serialized.

This patch adds a mutex to the layout stateid, and locks it when
checking the layout stateid's seqid. The mutex is held over the entire
operation and released after the seqid is bumped.

Note that in the case of CB_LAYOUTRECALL we must move the increment of
the seqid and setting into a new cb "prepare" operation. The lease
infrastructure will call the lm_break callback with a spinlock held, so
and we can't take the mutex in that codepath.

2b63482185 nfsd: fix clid_inuse on mount with security change
In bakeathon testing Solaris client was getting CLID_INUSE error when
doing a krb5 mount soon after an auth_sys mount, or vice versa.

That's not really necessary since in this case the old client doesn't
have any state any more:

	http://tools.ietf.org/html/rfc7530#page-103

	"when the server gets a SETCLIENTID for a client ID that
	currently has no state, or it has state but the lease has
	expired, rather than returning NFS4ERR_CLID_INUSE, the server
	MUST allow the SETCLIENTID and confirm the new client ID if
	followed by the appropriate SETCLIENTID_CONFIRM."

This doesn't fix the problem completely since our client_has_state()
check counts openowners left around to handle close replays, which we
should probably just remove in this case.

778620364e sunrpc/cache: make cache flushing more reliable.
The caches used to store sunrpc authentication information can be
flushed by writing a timestamp to a file in /proc.

This timestamp has a one-second resolution and any entry in cache that
was last_refreshed *before* that time is treated as expired.

This is problematic as it is not possible to reliably flush the cache
without interrupting NFS service.
If the current time is written to the "flush" file, any entry that was
added since the current second started will still be treated as valid.
If one second beyond than the current time is written to the file
then no entries can be valid until the second ticks over.  This will
mean that no NFS request will be handled for up to 1 second.

To resolve this issue we make two changes:

1/ treat an entry as expired if the timestamp when it was last_refreshed
  is before *or the same as* the expiry time.  This means that current
  code which writes out the current time will now flush the cache
  reliably.

2/ when a new entry in added to the cache -  set the last_refresh timestamp
  to 1 second *beyond* the current flush time, when that not in the
  past.
  This ensures that newly added entries will always be valid.

Now that we have a very reliable way to flush the cache, and also
since we are using "since-boot" timestamps which are monotonic,
change cache_purge() to set the smallest future flush_time which
will work, and leave it there: don't revert to '1'.

Also disable the setting of the 'flush_time' far into the future.
That has never been useful and is now awkward as it would cause
last_refresh times to be strange.
Finally: if a request is made to set the 'flush_time' to the current
second, assume the intent is to flush the cache and advance it, if
necessary, to 1 second beyond the current 'flush_time' so that all
active entries will be deemed to be expired.

As part of this we need to add a 'cache_detail' arg to cache_init()
and cache_fresh_locked() so they can find the current ->flush_time.

cc6a7aab55 sunrpc: avoid warning in gss_key_timeout
The gss_key_timeout() function causes a harmless warning in some
configurations, e.g. ARM imx_v6_v7_defconfig with gcc-5.2, if the
compiler cannot figure out the state of the 'expire' variable across
an rcu_read_unlock():

net/sunrpc/auth_gss/auth_gss.c: In function 'gss_key_timeout':
net/sunrpc/auth_gss/auth_gss.c:1422:211: warning: 'expire' may be used uninitialized in this function [-Wmaybe-uninitialized]

To avoid this warning without adding a bogus initialization, this
rewrites the function so the comparison is done inside of the
critical section. As a side-effect, it also becomes slightly
easier to understand because the implementation now more closely
resembles the comment above it.

0d0f4aab4e lockd: get rid of reference-counted NSM RPC clients
Currently we have reference-counted per-net NSM RPC client
which created on the first monitor request and destroyed
after the last unmonitor request. It's needed because
RPC client need to know 'utsname()->nodename', but utsname()
might be NULL when nsm_unmonitor() called.

So instead of holding the rpc client we could just save nodename
in struct nlm_host and pass it to the rpc_create().
Thus ther is no need in keeping rpc client until last
unmonitor request. We could create separate RPC clients
for each monitor/unmonitor requests.

So, revert old design and make AMD0010 looks like other ones.

   the secondary CPU was booted on. The bootloader will set this value
   to non-zero, after sucessfull power up of secondary CPU. In the same
   time this booted CPU will stuck (spin) waiting for software reset.
2. Exynos542x entry address for secondary CPU boot up after system

ceca418adf ARM: exynos_defconfig: Enable WiFi-Ex as a module instead built-in
The Marvell WiFi-Ex driver tries to load a firmware on probe. So if the
driver is built-in and probed before a firmware is available, this is
not loaded and the chip does not work.

This happens for example if an initramfs isn't used since the driver is
probed before the root filesystem is mounted.

Change the default config since the driver isn't needed for machines to
boot and is more convenient to have it enabled as a module to avoid
requiring an initramfs or to have the firmware built into the kernel.

5b6ce5216e ARM: exynos_defconfig: Disable simplefb support
The simplefb driver allows the kernel to render on a pre-allocated
buffer that's been initialized by firmware before the kernel boots.

This option was enabled to have display working on the Exynos5250
Snow Chromebook by commit da9d0fbf5e ("ARM: exynos: defconfig
update") since proper DRM/KMS support did not exist at that time.

But now that the Exynos DRM driver has support for this hardware,
there is no need to have simplefb enabled. In fact, if a user has
a u-boot that injects the simplefb dev node to the FDT before pass
it to the kernel, display won't be properly initialized and only a
blank screen will be shown since there isn't a proper handoff from
the simplefb driver to the Exynos DRM driver.

There are some differences of mobile storage host between exynos3250
and exnos5250. For example, exynos3250 supports the HS400 mode, but
exynos5250 doesn't support it.
Since exynos3250 can perform the similar function with exynos5420
compatible, this patch changes the compatible from exynos5250 to
exynos5420 for mshc.
