A couple of changes to the Tegra maintainership setup:
I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.
Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.
Finally, update the git URL since I'll take over running the main repo
for a while.
Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).

Rather than open coding a binary search use the standard bsearch() using
the comparison function we're already using for sort() on insert. This
fixes a lockup I was observing due to iterating on min <= max rather
than min < max when we fail to look up.

We shouldn't change the event flags of input devices after they get registered.
Otherwise, udev will not get notified of these flags and cannot setup the
devices properly.
This fixes the probing to set the input event flags on the input_mapped callback
instead of the probe function.

This patch cleans up several issues with VLANs on igb after the recent
changes that were meant to leave the VLANs enabled/disable via the
netdev->features flags.
Specifically the Rx VLAN settings were being dropped after reset due to the
fact that they were not being restored correctly. In addition I removed
the IRQ disable/enable since those were in place to protect the setting of
vlgrp.

This change is meant to cleanup some of the IVAR register configuration.
igb_assign_vector had become pretty large with multiple copies of the same
general code for setting the IVAR. This change consolidates most of that
code by adding the igb_write_ivar function which allows us just to compute
the index and offset and then use that information to setup the IVAR.

The goal of this patch is to include more information about the host
environment into the perf.data so it is more self-descriptive. Overtime,
profiles are captured on various machines and it becomes hard to track
what was recorded, on what machine and when.
This patch provides a way to solve this by extending the perf.data file
with basic information about the host machine. To add those extensions,
we leverage the feature bits capabilities of the perf.data format. The
change is backward compatible with existing perf.data files.
We define the following useful new extensions:
- HEADER_HOSTNAME: the hostname
- HEADER_OSRELEASE: the kernel release number
- HEADER_ARCH: the hw architecture
- HEADER_CPUDESC: generic CPU description
- HEADER_NRCPUS: number of online/avail cpus
- HEADER_CMDLINE: perf command line
- HEADER_VERSION: perf version
- HEADER_TOPOLOGY: cpu topology
- HEADER_EVENT_DESC: full event description (attrs)
- HEADER_CPUID: easy-to-parse low level CPU identication
The small granularity for the entries is to make it easier to extend
without breaking backward compatiblity. Many entries are provided as
ASCII strings.
Perf report/script have been modified to print the basic information as
easy-to-parse ASCII strings. Extended information about CPU and NUMA
topology may be requested with the -I option.
Thanks to David Ahern for reviewing and testing the many versions of
this patch.

When requesting multiple events, say:
# perf top -e instructions -e cycles -e cache-misses
The first screen lets the user chose what to see first, then to switch
one can either use the left key to get back to the event menu or simply
use TAB to go the next and shift+TAB to go the prev.
When using TAB/UNTAB the call to perf_evlist__set_selected(event) was

The perf report -n option was broken because it was not reporting the
correct number of samples depending on the sorting mode. By default,
samples are sorted by comm,dso,sym. That means that samples for the same
command (binary) get collapsed.
The hists__collapse_insert_entry() had a bug whereby it was aggregating
the number of events observed (periods) but not the number of samples.
Consequently, the number of samples reported could be below reality. The
percentage remained correct because based on the periods.
This patch fixes the problem by also aggregating the number of samples.
Here is an example:
$ perf report -n --stdio
12.38% 842 pong [kernel.kallsyms] [k] __lock_acquire
Here pong (a ctxsw stress test), is the only program running
and thus it is the only one responsible for the lock_acquire samples.
If we change the sorting mode:
$ perf report -n --stdio --sort=sym
12.38% 1732 [k] __lock_acquire
The actual number of samples is shown.
With the fix:
$ perf report -n --stdio
12.38% 1732 pong [kernel.kallsyms] [k] __lock_acquire

To disable it either:
1. Make sure newt-devel is not installed when building it
2. Use 'perf top --stdio' just like with report
3. Edit your ~/.perfconfig or system wide config and have this there:
[tui]
top = off
But you shouldn't, since the TUI is so much more powerful, has
integration with annotation and where lots more interesting features
will be developed, so if something annoys you (the colors?) just let me
know and I'll do my best to make it pleasant as a default.

I.e. when in the annotate TUI window, if Enter is pressed over an
assembly line with a 'callq' it will try to open another TUI window with
that symbol.
This is just a proof of concept and works only on x86_64, more work is
needed to support kernel modules, userland, other arches, etc, but
should already be useful as-is.

This actually fixes several problems we had in the old 'perf top':
1. Unresolved symbols not show, limitation that came from the old
"KernelTop" codebase, to solve it we would need to do changes
that would make sym_entry have most of the hist_entry fields.
2. It was using the number of samples, not the sum of sample->period.
And brings the --sort code that allows us to have all the views in
'perf report', for instance:
[root@emilia ~]# perf top --sort dso
PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs)
------------------------------------------------------------------------------
31.59% libcrypto.so.1.0.0
21.55% [kernel]
18.57% libpython2.6.so.1.0
7.04% libc-2.12.so
6.99% _backend_agg.so
4.72% sshd
1.48% multiarray.so
1.39% libfreetype.so.6.3.22
1.37% perf
0.71% libgobject-2.0.so.0.2200.5
0.53% [tg3]
0.48% libglib-2.0.so.0.2200.5
0.44% libstdc++.so.6.0.13
0.40% libcairo.so.2.10800.8
0.38% libm-2.12.so
0.34% umath.so
0.30% libgdk-x11-2.0.so.0.1800.9
0.22% libpthread-2.12.so
0.20% libgtk-x11-2.0.so.0.1800.9

0.08% libX11.so.6.3.0
0.07% [vdso]
0.06% cyclictest
^C
All the filter lists can be used as well: --dsos, --comms, --symbols,
etc.
The 'perf report' TUI is also reused, being possible to apply all the
zoom operations, do annotation, etc.
This change will allow multiple simplifications in the symbol system as
well, that will be detailed in upcoming changesets.

The LEON MMU Model (SRMMU) does not implement MMu Table probing
in hardware, instead it is implemented in software. However the
software implementation does not return the PTE as it should which
always results in INVALID entires and the PROM mappings are not
inherited as they should during startup. The following patch
removes the masking of the PTE.

This allows passing a timer to be run periodically, which will update
the hists tree that then gers refreshed on the screen, just like the
Live mode (symbol entries, annotation) we already have in 'perf top
--tui'.
Will be used by the new hist_entry/hists based 'top' tool.

By using a mutex just for inserting and rotating two hist_entry rb
trees, so that when sorting we can get the last batch of entries created
from the ring buffer, merge it with whatever we have processed so far
and show the output while new entries are being added.
The 'report' tool continues, for now, to do it without threading, but
will use this in the future to allow visualization of results in long
perf.data sessions while the entries are being processed.
The new 'top' tool will be the first user.

Just like --show-nr-samples, to help in diagnosing problems in the
tools.

Stop using this python/OOP convention, doesn't really helps. Will do
more from time to time till we get it cleaned up in all of /perf.

This change will combine the writes of tx_buffer_info and the Tx data
descriptors into a single function. The advantage of this is that we can
avoid needless memory reads from the buffer info struct and speed things up
by keeping the accesses to the local registers.

This change is meant to combine all of the TX flags fields into one u32
flags field so that it can be stored into the tx_buffer_info structure.
This includes the time stamp flag as well as mapped_as_page flag info.

This change is meant to improve the readability of the driver by separating
out the cmd_type configuration and the olinfo configuration into their own
functions. By doing this it is much easier to determine which ingredients
go into setting up these to portions of the descriptor.
