Merge leftovers from Andrew Morton:
"A few leftovers: ocfs2, gcov, RTC"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
rtc: s5m: consolidate two device type switch statements
rtc: s5m: add support for S2MPS14 RTC
rtc: s5m: support different register layout
rtc: s5m: use shorter time of register update
rtc: s5m: remove undocumented time init on first boot
mfd/rtc: sec/s5m: rename SEC* symbols to S5M
gcov: add support for GCC 4.9
ocfs2/o2net: incorrect to terminate accepting connections loop upon rejecting an invalid one
In probe the configuration of driver for different chipsets was done in
two switch (pdata->device_type) statements. Consolidate them into one
switch statement to increase code readability.
Additionally check the return value of regmap_irq_get_virq and exit
probe on error.

Add support for S2MPS14 to the rtc-s5m driver. Differences in S2MPS14
(in comparison to S5M8767):
- Layout of registers
- Lack of century support for time and alarms (7 registers used for
storing time/alarm)
- Two buffer control registers: WUDR and RUDR
- No register for enabling writing time
- RTC interrupts are reported in main PMIC I2C device

Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver:
1. Add a map of registers used by the driver which differ between
the chipsets (S5M876X and S2MPS14).
2. Move code of checking for alarm pending to separate function.

The default is 7.32 ms which is too long and leads to warnings when

Remove the code for initializing time if this is first boot.
The code for detecting first boot uses undocumented field RTC_TCON in
RTC_UDR_CON register. According to S5M8767's datasheet this field is
reserved. On S2MPS14 it is not documented at all.
On device first boot the registers will be initialized with reset value
(2000-01-01 00:00:00).
The code might work on S5M8763 but still this does not look like a task
for RTC driver.

A new counter (time profile) is added. The total number is 9 now.
A new profile merge function __gcov_merge_time_profile is added.
See gcc/gcov-io.h and libgcc/libgcov-merge.c
For the first change, the layout of struct gcov_info is affected.
For the second one, a dummy function is added to kernel/gcov/base.c
similarly.

Right now when people try to report issues in the kernel they send stack
dumps to eachother, which looks something like this:
[ 6.906437] [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20
[ 6.907121] [<ffffffff84388ce8>] dump_stack+0x52/0x7f
[ 6.907640] [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110
[ 6.908281] [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0
[ 6.908870] [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22
[ 6.909480] [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0
[...]
However, most of the text you get is pure garbage.
The only useful thing above is the function name. Due to the amount of
different kernel code versions and various configurations being used,
the kernel address and the offset into the function are not really
helpful in determining where the problem actually occured.
Too often the result of someone looking at a stack dump is asking the
person who sent it for a translation for one or more 'addr2line'
translations. Which slows down the entire process of debugging the
issue (and really annoying).
The decode_stacktrace script is an attempt to make the output more
useful and easy to work with by translating all kernel addresses in the
stack dump into line numbers. Which means that the stack dump would
look like this:
[ 635.148361] dump_stack (lib/dump_stack.c:52)
[ 635.149127] warn_slowpath_common (kernel/panic.c:418)
[ 635.150214] warn_slowpath_null (kernel/panic.c:453)
[ 635.151031] _oalloc_pages_slowpath+0x6a/0x7d0
[ 635.152171] ? zone_watermark_ok (mm/page_alloc.c:1728)
[ 635.152988] ? get_page_from_freelist (mm/page_alloc.c:1939)
[ 635.154766] __alloc_pages_nodemask (mm/page_alloc.c:2766)
It's pretty obvious why this is better than the previous stack dump
before.
Usage is pretty simple:
./decode_stacktrace.sh [vmlinux] [base path]
Where vmlinux is the vmlinux to extract line numbers from and base path
is the path that points to the root of the build tree, for example:
./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log
The stack trace should be piped through it (I, for example, just pipe
the output of the serial console of my KVM test box through it).

The kernel has no concept of capabilities with respect to inodes; inodes
exist independently of namespaces. For example, inode_capable(inode,
CAP_LINUX_IMMUTABLE) would be nonsense.
This patch changes inode_capable to check for uid and gid mappings and
renames it to capable_wrt_inode_uidgid, which should make it more
obvious what it does.

[ Fix htons -> ntohs to make sparse happy. - Roland ]

This patch adds iWARP Port Mapper (IWPM) Version 2 support. The iWARP
Port Mapper implementation is based on the port mapper specification
section in the Sockets Direct Protocol paper -
http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf
Existing iWARP RDMA providers use the same IP address as the native
TCP/IP stack when creating RDMA connections. They need a mechanism to
claim the TCP ports used for RDMA connections to prevent TCP port
collisions when other host applications use TCP ports. The iWARP Port
Mapper provides a standard mechanism to accomplish this. Without this
service it is possible for RDMA application to bind/listen on the same
port which is already being used by native TCP host application. If
that happens the incoming TCP connection data can be passed to the
RDMA stack with error.
The iWARP Port Mapper solution doesn't contain any changes to the
existing network stack in the kernel space. All the changes are
contained with the infiniband tree and also in user space.
The iWARP Port Mapper service is implemented as a user space daemon
process. Source for the IWPM service is located at
http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary
The iWARP driver (port mapper client) sends to the IWPM service the
local IP address and TCP port it has received from the RDMA
application, when starting a connection. The IWPM service performs a
socket bind from user space to get an available TCP port, called a
mapped port, and communicates it back to the client. In that sense,
the IWPM service is used to map the TCP port, which the RDMA
application uses to any port available from the host TCP port
space. The mapped ports are used in iWARP RDMA connections to avoid
collisions with native TCP stack which is aware that these ports are
taken. When an RDMA connection using a mapped port is terminated, the
client notifies the IWPM service, which then releases the TCP port.
The message exchange between the IWPM service and the iWARP drivers
(between user space and kernel space) is implemented using netlink
sockets.
1) Netlink interface functions are added: ibnl_unicast() and
ibnl_mulitcast() for sending netlink messages to user space
2) The signature of the existing ibnl_put_msg() is changed to be more
generic
3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW
corresponding to the two iWarp drivers - nes and cxgb4 which use
the IWPM service
4) Enums are added to enumerate the attributes in the netlink
messages, which are exchanged between the user space IWPM service
and the iWARP drivers

to help out the rest of the kernel to ease their use of trace events.
The big change for this release is the allowing of other tracers, such
as the latency tracers, to be used in the trace instances and allow
for function or function graph tracing to be in the top level
simultaneously"

Pull cgroup updates from Tejun Heo:
"A lot of activities on cgroup side. Heavy restructuring including
locking simplification took place to improve the code base and enable
implementation of the unified hierarchy, which currently exists behind
a __DEVEL__ mount option. The core support is mostly complete but
individual controllers need further work. To explain the design and
rationales of the the unified hierarchy
Documentation/cgroups/unified-hierarchy.txt
is added.
Another notable change is css (cgroup_subsys_state - what each
controller uses to identify and interact with a cgroup) iteration
update. This is part of continuing updates on css object lifetime and
visibility. cgroup started with reference count draining on removal
way back and is now reaching a point where csses behave and are
iterated like normal refcnted objects albeit with some complexities to
allow distinguishing the state where they're being deleted. The css
iteration update isn't taken advantage of yet but is planned to be
used to simplify memcg significantly"

gfp passed to create_qp_common() instead of using hardcoded GFP_KERNEL

This function is supposed to return true if the new load imbalance is
worse than the old one. It didn't. I can only hope brown paper bags
are in style.
Now things converge much better on both the 4 node and 8 node systems.
I am not sure why this did not seem to impact specjbb performance on the
4 node system, which is the system I have full-time access to.
This bug was introduced recently, with commit e63da03639 ("sched/numa:
Allow task switch if load imbalance improves")

shrink_inactive_list() used to wait 0.1s to avoid congestion when all
the pages that were isolated from the inactive list were dirty but not
under active writeback. That makes no real sense, and apparently causes
major interactivity issues under some loads since 3.11.
The ostensible reason for it was to wait for kswapd to start writing
pages, but that seems questionable as well, since the congestion wait
code seems to trigger for kswapd itself as well. Also, the logic behind
delaying anything when we haven't actually started writeback is not
clear - it only delays actually starting that writeback.
We'll still trigger the congestion waiting if
(a) the process is kswapd, and we hit pages flagged for immediate
reclaim
(b) the process is not kswapd, and the zone backing dev writeback is
actually congested.
This probably needs to be revisited, but as it is this fixes a reported
regression.
