Lifted from proposal for in kernel interface built on the out of staging
branch.

Two elements here:
* Map as defined in "inkern.h"
* Matching code to actually get the iio_dev and channel
that we want from the global list of IIO devices.
V4: Everything now built if iio is built (rather than being optional)
    Removal race condition prevented by using info pointer as a check
    of removal under a lock.
V3: Drop the option of registering / getting channels using dev pointer.
Stick to name only as suggested by Mark Brown (this has caused user
confusion in the regulator framework.)
V2: As per Greg KH suggestion, move over to registration by passing
the tables into the provider drivers (how regulator does it).
This does not prevent us using the original more flexible approach
if at a later date there is a usecase that demands it.

This prevents use of provider callbacks after it has been unregistered.
Note that all code using this that can be called from a consumer *must*
check the pointer before using and hold the info_exist_lock throughout
the usage of the callbacks in info.

In order to detect WDT feature on the dsp code, we need to
find the symbol used to enable it inside the baseimage.

This should fix the warning comming from L3 driver:

    WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq...
    In-band Error seen by IVA_SS  at address 0
    ...

That occurs because the dsp tries to access wdt3 registers when the clock
for those registers is not enabled.

In order to detect it at runtime, we need the code handling wdt
clock available at runtime to decide whether to enable or disable
based on the baseimage symbols. Default timeout has been set to 5
seconds.

Downside is that we will lose the option to set a custom timeout
for overflow, but than can be added (if needed) as part of debugfs.

p80211item_pstr6_t is the size of "msg1.bssid" (16 bytes) but
msg1.bssid.data is type p80211pstr6_t and it is smaller (7 bytes).  We
had just set that memory to zeroes earlier and now we're writing over it
with 0xff because we're writing past the end of the struct.

I don't know if this actually causes a problem.  It may be that we
initialize the extra 0xff bytes correctly later.  But the current code
is obviously wrong and we should fix it.

Commit 9256a478 fixed a deadlock condition, being sure that the buddy
list spinlock is always taken before the page spinlock.

However in zbud_free_and_delist() locking order is the opposite
(page lock -> list lock).

Possible unsafe locking scenario (reported by lockdep):

        CPU0                    CPU1
        ----                    ----
   lock(&(&zbpg->lock)->rlock);
                                lock(zbud_budlists_spinlock);
                                lock(&(&zbpg->lock)->rlock);
   lock(zbud_budlists_spinlock);

Fix by grabbing the locks in opposite order in zbud_free_and_delist().

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd.  For calling from outside interrupts, netif_rx_ni exists.

This stops the error "NOHZ: local_softirq_panding 08" that happens on
some machines with NOHZ and plip --- it is caused by the fact that
softirq is pending and ksoftirqd is sleeping.

Ramster can't be a module (yet) and depends on CONFIGFS_FS=y, but
allmodconfig builds with CONFIGFS_FS=m, which breaks the build.
And forcing CONFIGFS_FS=y with select breaks the build in other ways.

In drivers/staging/rtl8192e/rtllib_softmac.c::rtllib_rx_assoc_resp()
we allocate memory for 'network' with kzalloc() and then proceed to
zero the already zeroed mem we got from kzalloc() with
memset(). That's redundant, so remove the memset()

We also fail to kfree() the memory we allocated for 'network' if we do not enter

  if (ieee->current_network.qos_data.supported == 1) {

and the variable then goes out of scope.

To fix that I simply moved the kfree() that was inside that 'if'
statement to instead be just after it. It then covers both the case
where we take the branch and when we don't.

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch adds new files necessary for ramster support:  The file
ramster.h declares externs and some pampd bitfield manipulation.  The
file zcache.h declares some zcache functions that now must be accessed
from the ramster glue code.  The file r2net.c is the glue between zcache
and the messaging layer, providing routines called from zcache that
initiate messages, and routines that handle messages by calling zcache.
TODO explains future plans for merging.
