MAINTAINERS: add linux-api for review of API/ABI changes

This makes it more likely that patch submitters will CC API/ABI changes to
the linux-api list, and tools like get_maintainer.pl will do so
automatically.

mm: convert some level-less printks to pr_*

printk is meant to be used with an associated log level.  There are some
instances of printk scattered around the mm code where the log level is
missing.  Add a log level and adhere to suggestions by
scripts/checkpatch.pl by moving to the pr_* macros.

Also add the typical pr_fmt definition so that print statements can be
easily traced back to the modules where they occur, correlated one with
another, etc.  This will require the removal of some (now redundant)
prefixes on a few print statements.

nbd: zero from and len fields in NBD_CMD_DISCONNECT.

Len field is already set to zero, but not the from field which is sent
as 0xfffffffffffffe00.  This makes no sense, and may cause confuse
server implementations doing sanity checks (qemu-nbd is an example.)

idle: remove cpu_idle() forward declarations

After all architectures were converted to the generic idle framework,
commit d190e8195b90 ("idle: Remove GENERIC_IDLE_LOOP config switch")
removed the last caller of cpu_idle().  The forward declarations in
header files were forgotten.

cris: update comments for generic idle conversion

As of commit 8dc7c5ecd8d0 ("cris: Use generic idle loop"), cris no
longer provides cpu_idle().

- On cris-v10, etrax_gpio_wake_up_check() is called from default_idle()
  instead of cpu_idle(),

- On cris-v32, etrax_gpio_wake_up_check() is not called from
  default_idle(), so remove this (copy-and-paste?) part.

ufs: sb mutex merge + mutex_destroy

Commit 788257d6101d ("ufs: remove the BKL") replaced BKL with mutex
protection using functions lock_ufs, unlock_ufs and struct mutex 'mutex'
in sb_info.

Commit b6963327e052 ("ufs: drop lock/unlock super") removed lock/unlock
super and added struct mutex 's_lock' in sb_info.

Those 2 mutexes are generally locked/unlocked at the same time except in
allocation (balloc, ialloc).

This patch merges the 2 mutexes and propagates first commit solution.
It also adds mutex destruction before kfree during ufs_fill_super
failure and ufs_put_super.

nfsd4: simplify server xdr->next_page use

The rpc code makes available to the NFS server an array of pages to
encod into.  The server represents its reply as an xdr buf, with the
head pointing into the first page in that array, the pages ** array
starting just after that, and the tail (if any) sharing any leftover
space in the page used by the head.

While encoding, we use xdr_stream->page_ptr to keep track of which page
we're currently using.

Currently we set xdr_stream->page_ptr to buf->pages, which makes the
head a weird exception to the rule that page_ptr always points to the
page we're currently encoding into.  So, instead set it to buf->pages -
1 (the page actually containing the head), and remove the need for a
little unintuitive logic in xdr_get_next_encode_buffer() and
xdr_truncate_encode.

nfsd: don't halt scanning the DRC LRU list when there's an RC_INPROG entry

Currently, the DRC cache pruner will stop scanning the list when it
hits an entry that is RC_INPROG. It's possible however for a call to
take a *very* long time. In that case, we don't want it to block other
entries from being pruned if they are expired or we need to trim the
cache to get back under the limit.

Fix the DRC cache pruner to just ignore RC_INPROG entries.

Merge branch 'akpm' (patches from Andrew Morton) into next

Merge more updates from Andrew Morton:

 - Most of the rest of MM.

   This includes "mark remap_file_pages syscall as deprecated" but the
   actual "replace remap_file_pages syscall with emulation" is held
   back.  I guess we'll need to work out when to pull the trigger on
   that one.

 - various minor cleanups to obscure filesystems

 - the drivers/rtc queue

 - hfsplus updates

 - ufs, hpfs, fatfs, affs, reiserfs

 - Documentation/

 - signals

 - procfs

 - cpu hotplug

 - lib/idr.c

 - rapidio

 - sysctl

 - ipc updates

net: qmi_wwan: add Olivetti Olicard modems

Lars writes: "I'm only 99% sure that the net interfaces are qmi
interfaces, nothing to lose by adding them in my opinion."

And I tend to agree based on the similarity with the two Olicard
modems we already have here.
