The reason to move cache_request() callback call from
sunrpc_cache_pipe_upcall() to cache_read() is that this garantees, that cache
access will be done userspace process context (only userspace process have
proper root context).
This is required for NFSd support in container: svc_export_request() (which is
cache_request callback) calls d_path(), which, in turn, traverse dentry up to
current->fs->root. Kernel threads always have global root, while container
have be in "root jail" - i.e. have it's own nested root.

Passing this pointer is redundant since it's stored on cache_detail structure,
which is also passed to sunrpc_cache_pipe_upcall () function.

For most of SUNRPC caches (except NFS DNS cache) cache_detail->cache_upcall is
redundant since all that it's implementations are doing is calling
sunrpc_cache_pipe_upcall() with proper function address argument.
Cache request function address is now stored on cache_detail structure and
thus all the code can be simplified.
Now, for those cache details, which doesn't have cache_upcall callback (the
only one, which still has is nfs_dns_resolve_template)
sunrpc_cache_pipe_upcall will be called instead.

This is a cleanup patch.
Such helpers like nfs_cache_init() and nfs_cache_destroy() are redundant,
because they are just a wrappers around sunrpc_init_cache_detail() and
sunrpc_destroy_cache_detail() respectively.
So let's remove them completely and move corresponding logic to
nfs_cache_register_net() and nfs_cache_unregister_net() respectively (since
they are called together anyway).

The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.
There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous

Patch a62a6e98 "ARM: OMAP2+: Disable code that currently does not work

are correct until OMAP_MBOX_FWK loses its dependency.

After reviewing the igb and ixgbe code I realized there are a few issues in
how the code is structured. Specifically we are not checking the size of the
buffers being used in transmits and we are not using the same value to
determine when to stop or start a Tx queue. As such the code is prone to be
buggy.
This patch makes it so that we have one value DESC_NEEDED that we will use for
starting and stopping the queue. In addition we will check the size of
buffers being used when setting up a transmit so as to avoid a possible buffer
overrun if we were to receive a frame with a block of data larger than 32K in
skb->data.

drm/i915: Fix blank panel at reopening lid
changed the register write sequence for restoring the backlight, which
helped prevent non-working backlights on some machines. Turns out that
the original sequence was the right thing to do for a different set of
machines. Worse, setting the backlight level _after_ enabling it seems
to reset it somehow. So we need to make that one conditional upon the
backlight having been reset to zero, and add the old one back.
Cargo-culting at it's best, but it seems to work.

Adding the flag to mac80211 already without testing was
clearly a mistake, one that we now pay for by having to
reserve bit 13 forever. The problem is cfg80211 doesn't
allow capability/rate changes for station entries that
were added unassociated, so the station entries cannot
be set up properly when marked associated.
Change the NL80211_FEATURE_FULL_AP_CLIENT_STATE value
to make it clear to userspace implementations that all
current kernels don't actually support it, even though
the previous bit is set, and of course also remove the
flag from mac80211 until we test and fix the issues.
