The lustre file system has a layered architecture with
libcfs as the lowest layer and LNet layered on top. Then
on top of LNet we run the lustre client. This patch moves
the libcfs module code out of lustre into the lnet tree.
This fits into the long term goal of eventually merging
libcfs into LNet.

19b2056ff7 staging: lustre: Correct missing newline
Several error messages are missing newline characters
at the end of the message. Newlines are added where
necessary and other minor corrections; no punctuation
at the end of an error message, add a return code to
the end of error messages, device name at the beginning,
etc.

There are just a couple of places where newlines are
removed and this is only in LDLM_DEBUG_NOLOCK. The definition
of LDLM_DEBUG_NOLOCK already has a newline in it and
resulted in double newlines printed.

0fbbced21a staging: lustre: LNet drop rule implementation
This is implementation of LNet Drop Rule, which can randomly drop
LNet messages at specified rate.

LNet Drop Rule can only be applied to receive side of message. User
can add drop_rule either on end point of cluster (client/server) or
on LNet routers.

Here are lctl command to control LNet Drop Rules:
 - net_drop_add -s SRC_NID -d DEST_NID --rate VALUE
   drop 1/@VALUE of messages from @SRC_NID to @DEST_NID

 - net_drop_del -s SRC_NID -d DEST_NID
   remove all drop rules from @SRC_NID to @DEST_NID

 - net_drop_list
   list all drop rules on current node

 Examples:
 - lctl net_drop_add -s *@o2ib0 -d 192.168.1.102@tcp 1000
   add new drop rule, it will drop 1/1000 messages from network o2ib0
   to 192.168.1.102@tcp

 - lctl net_drop_add -s 10.8.6.123@o2ib1 -d * 500
   add new drop rule, it will drop 1/500 messages from 10.8.6.123@o2ib1

a921e9bd4e isdn: i4l: move active-isdn drivers to staging
The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.

All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.

Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

01ed1e1504 isdn: icn: remove a #warning
The icn driver currently produces an unconditional #warning whenever
we build it, introduced by Karsten Keil back in 2003:

 #warning TODO test headroom or use skb->nb to flag ACK

Karsten's original commit (from BitKeeper) contains this description:

    - here are lot of bugs left, so ISDN is not stable yet but
      I think it's really time to fix it, even if it need some cycles
      to get it right (normally I'm only send patches if it works 100% for
      me).
    - I add some additional #warnings to address places which need fixing
      (I hope that some of the other ISDN developer jump in)

Apparently this has not happened, and it is unlikely that it ever will,
given that the driver doesn't seem to work. No substantial bug fixes
other than janitorial cleanups have happened in the driver since then,
and I see no indication that anyone who patched it had the hardware.

We should probably either remove the driver, or remove all of i4l,
but for now, this shuts up the distracting #warning by turning it
into a comment.

"include/linux/bitops.h" should not be used there.

Replace the use of the `BIT` macro with hexadecimal constants of the
same value.  The `BIT` macro replaced expressions of the form `(1 << N)`
in this file originally, but reverting back to that form would encourage
patches changing them back to use the `BIT` macro.

dda68765d7 Staging: comedi: s626.c: Remove unused functions
The functions s626_get_clk_mult, s626_get_clk_mult, s626_get_enc_mode,
s626_set_index_pol are not used anywhere in the kernel so they can be
removed. This also cleans the code. Grepped to find the occurences.

d2b0fc6e29 staging: comedi: drivers: Remove use of deprecated pci API
Replace pci_[alloc|free]_consistent occurences with
dma_[alloc|free]_coherent.

The Coccinelle semantic patch that was used to make some of these
changes is as follows:
@deprecated@
idexpression id;
position p;
@@

(
  pci_dma_supported@p ( id, ...)
|
  pci_alloc_consistent@p ( id, ...)
)

@bad1@
idexpression id;
position deprecated.p;
@@
...when != &id->dev
   when != pci_get_drvdata ( id )
   when != pci_enable_device ( id )
(
  pci_dma_supported@p ( id, ...)
|
  pci_alloc_consistent@p ( id, ...)
)

@depends on !bad1@
idexpression id;
expression direction;
position deprecated.p;
@@

(
- pci_dma_supported@p ( id,
+ dma_supported ( &id->dev,
...
+ , GFP_KERNEL
  )
|
- pci_alloc_consistent@p ( id,
+ dma_alloc_coherent ( &id->dev,
...
+ , GFP_KERNEL
  )
)

alloc_and_init_dma_members does not affect the interrupt status and is
only called by auto_attach, which also does not affect the interrupt
status. auto_attach() also contains a call to comedi_alloc_devpriv()
which calls kzalloc with GFP_KERNEL flag.  Thus, there seems to be no
danger that dma_alloc_coherent can be called with interrupts turned
off, and GFP_KERNEL can be used.

1e5a05d57c staging: comedi: Use macro DIV_ROUND_CLOSEST
Occurences of the computation (x +d/2)/d can be replaced with
the macro DIV_ROUND_CLOSEST.

This was detected by the following Coccinelle script.

@@
expression e1,e2;
@@
(
- ((e1) + e2/2) / (e2)
+ DIV_ROUND_CLOSEST(e1,e2)
|
- ((e1) + (e2/2)) / (e2)
+ DIV_ROUND_CLOSEST(e1,e2)
)

Since some lines exceeded the 80 character limit,
some changes were made by hand.
