The primary purpose of the UUIDs is to enable generation of EIR and AD
data. In these data formats the UUIDs are split into separate fields
based on whether they're 16, 32 or 128 bit UUIDs. To make the generation
of these data fields simpler this patch adds a type member to the
bt_uuid struct and assigns a value to it as soon as the UUID is added to
the kernel. This way the type doesn't need to be calculated each time
the UUID list is later iterated.

We should be encoding UUIDs to the EIR data in the same order that they
were added to the kernel, i.e. each UUID should be added to the end of
the UUIDs list. This patch fixes the issue by using list_add_tail
instead of list_add for storing the UUIDs.

This reverts commit 324d003b0cd82151adbaecefef57b73f7959a469.
The deadlock turned out to be caused by a workqueue limitation that has
now been worked around in the RPC code (see comment in rpc_free_task).

tk_xprt is just a shortcut for tk_client->cl_xprt, however cl_xprt is

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
. Make some POWER7 events available in sysfs, equivalent to
what was done on x86, from Sukadev Bhattiprolu.
. Add event group view, from Namyung Kim:
To use it, 'perf record' should group events when recording. And then perf
report parses the saved group relation from file header and prints them
together if --group option is provided. You can use 'perf evlist' command to
see event group information:
$ perf record -e '{ref-cycles,cycles}' noploop 1
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]
$ perf evlist --group
{ref-cycles,cycles}
With this example, default perf report will show you each event
separately like this:
$ perf report
...
# group: {ref-cycles,cycles}
# ========
# Samples: 3K of event 'ref-cycles'
# Event count (approx.): 3153797218
#
# Overhead Command Shared Object Symbol
# ........ ....... ................. ..........................
99.84% noploop noploop [.] main
0.07% noploop ld-2.15.so [.] strcmp
0.03% noploop [kernel.kallsyms] [k] timerqueue_del
0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu
0.02% noploop [kernel.kallsyms] [k] account_user_time
0.01% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask
0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe
# Samples: 3K of event 'cycles'
# Event count (approx.): 3722310525
#
# Overhead Command Shared Object Symbol
# ........ ....... ................. .........................
99.76% noploop noploop [.] main
0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock
0.06% noploop [kernel.kallsyms] [k] find_get_page
0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu
0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks
0.02% noploop [kernel.kallsyms] [k] __current_kernel_time
0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe
In this case the event group information will be shown in the end of
header area. So you can use --group option to enable event group view.
$ perf report --group
...
# group: {ref-cycles,cycles}
# ========
# Samples: 7K of event 'anon group { ref-cycles, cycles }'
# Event count (approx.): 6876107743
#
# Overhead Command Shared Object Symbol
# ................ ....... ................. ..........................
99.84% 99.76% noploop noploop [.] main
0.07% 0.00% noploop ld-2.15.so [.] strcmp
0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del
0.03% 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu
0.02% 0.00% noploop [kernel.kallsyms] [k] account_user_time
0.01% 0.00% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask
0.00% 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe
0.00% 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock
0.00% 0.06% noploop [kernel.kallsyms] [k] find_get_page
0.00% 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks
0.00% 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time
As you can see the Overhead column now contains both of ref-cycles and
cycles and header line shows group information also - 'anon group {
ref-cycles, cycles }'. The output is sorted by period of group leader
first.
If perf.data file doesn't contain group information, this --group
option does nothing. So if you want enable event group view by
default you can set it in ~/.perfconfig file:
$ cat ~/.perfconfig
[report]
group = true
It can be overridden with command line if you want:
$ perf report --no-group

For standard IEEE MII-compatible transceivers, the kernel has generic
register and bit definitions. Use those instead of redundant local
defines.
Do not replace references of MII_CR_SPEED_10 with BMCR_SPEED10 (0x0000)
when it is not necessary (i.e. when it is bitwise OR'ed with another
value).
Some whitespace issues in the surrounding context of the above changes are
also cleaned up.

The wanrouter support was identified earlier as unused for years,
and so the previous commit totally decoupled it from the kernel,
leaving the related wanrouter files present, but totally inert.
Here we take the final step in that cleanup, by doing a wholesale
removal of these files. The two step process is used so that the
large deletion is decoupled from the git history of files that we
still care about.
The drivers deleted here all were dependent on the Kconfig setting
CONFIG_WAN_ROUTER_DRIVERS.
A stub wanrouter.h header (kernel & uapi) are left behind so that
drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that
we don't accidentally break userspace that expected these defines.

The original suggestion to delete wanrouter started earlier
with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc
("net/wanrouter: Deprecate and schedule for removal") in May 2012.
More importantly, Dan Carpenter found[1] that the driver had a
fundamental breakage introduced back in 2008, with commit
7be6065b39c3 ("netdevice wanrouter: Convert directly reference of
netdev->priv"). So we know with certainty that the code hasn't been
used by anyone willing to at least take the effort to send an e-mail
report of breakage for at least 4 years.
This commit does a decouple of the wanrouter subsystem, by going
after the Makefile/Kconfig and similar files, so that these mainline
files that we are keeping do not have the big wanrouter file/driver
deletion commit tied into their history.
Once this commit is in place, we then can remove the obsolete cyclomx
drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.
