Fix up conflicts in arch/x86/kernel/kprobes.c manually.
Ingo's tree did the insane "add volatile to const array", which just
doesn't make sense ("volatile const"?). But we could remove the const
*and* make the array volatile to make doubly sure that gcc doesn't
optimize it away..
Also fix up kernel/trace/ring_buffer.c non-data-conflicts manually: the
reader_lock has been turned into a raw lock by the core locking merge,
and there was a new user of it introduced in this perf core merge. Make
sure that new use also uses the raw accessor functions.

The __perf_evsel__open routing was grouping just the threads for that
specific events per cpu when we want to group all threads in all events
to the first fd opened on that cpu.
So pass the xyarray with the first event, where the other events will be
able to get that first per cpu fd.
At some point top and record will switch to using perf_evlist__open that
takes care of this detail and probably will also handle the fallback
from hw to soft counters, etc.

This was done to resolve a conflict in the
drivers/staging/comedi/drivers/ni_labpc.c file that resolved a build
bugfix in Linus's tree with a "better" bugfix that was in the
staging-next tree that resolved the issue in a more complete manner.

On some tests that do multiple boots (patchcheck, bisect, etc), the build
of the next kernel to run may finish before the stable kernel has finished
booting. Then the install of the new kernel will fail when it tries to connect
as the machine has not finished the boot process.
Do one more monitor flush to make sure the machine is up and running before
trying to connect to it again.

Fixing the way the tracing information is stored within record command.
The current implementation is causing issues for pipe output.
Following commands fail currently:
perf script syscall-counts ls
perf record -e syscalls:sys_exit_read ls | ./perf report -i -
The tracing information is part of the perf data file. It contains
several files from within the tracing debugfs and procs directories.
Beside some static header files, for each tracing event the format
file is added. The /proc/kallsyms file is also added.
The tracing data are stored with preceeding size. This is causing some
dificulties for pipe output, since there's no way to tell debugfs/proc
file size before reading it. So, for pipe output, all the debugfs files
were read twice. Once to get the overall size and once to store the
content itself. This can cause problem in case any of these file
changed, within the storage time.
To fix this behaviour and ensure the integrity of the tracing data, we:
- read debugfs/proc file into the temp file
- get temp file size and dump it to the pipe
- dump the temp file contents to the pipe

When setting the next kernel to boot to with grub, do not opencode
the reboot operation. The normal reboot operation can be modified by
config options (namely POWERCYCLE_AFTER_REBOOT). This needs to affect
all reboots. Remove the opencoded reboot to make sure that any changes
to the reboot code also affect all reboots.

Following the 'perf report' model we don't zap hist_entry instances from
the rb tree, we just keep them with he->filtered set to a mask of the
filters applied to it (thread, parent, DSO so far).
In top we need to decay even filtered entries, but we better not touch
total_period for them...
Now everything seems to work when filters are applied on top as they
worked in 'report', i.e. both dynamic and static hist entry browsing
works with filters.

Feature bitmap is declared as an array of unsigned longs -- not good
since its size can differ between the host that generated the data file
and the host analyzing the file.
We need to handle endianness, but we don't know the size of the unsigned
long where the file was generated. Take a best guess at determining it:
try 64-bit swap first (ie., file created on a 64-bit host), and check if
the hostname feature bit is set (this feature bit is forced on as of
fbe96f2). If the bit is not, undo the 64-bit swap and try a 32-bit
swap. If the hostname bit is still not set (e.g., older data file), punt
and fallback to the original behavior -- clearing all feature bits and
setting buildid.

readlink() never zero terminates the provided buffer.
Therefore we already do
buffer[count] = 0;
This leads to an off-by-one buffer corruption as readlink()
might return the full size of the buffer.
The common technique is to reduce the buffer size by one.
Another fix would be to check
if (count < 0 || count == sizeof(buffer))
fatal();
Reducing the buffer size by one is easier IMHO.

The order for some of the keywords on a section line
(TEST_START or DEFAULTS) does not really matter. Simply need
to remove the keyword from the line as we process it and
evaluate the next keyword in the line. By removing the keywords
as we find them, we do not need to keep track of where on the
line they were found.

The make_min_config test will turn off one config at a time and check
if the config boots or not, and if it does, it will remove that config
plus any config that depended on that config.
ktest already looks if a config has a dependency and will try the
dependency config first. But by sorting the configs and trying the
config with the most configs dependent on it, we can shrink the
minconfig faster.

The OVERRIDE keyword will allow options defined in the given
DEFAULTS section to override options defined in previous DEFAULT
sections.
Normally, options will error if they were previous defined.
The OVERRIDE keyword allows options that have been previously
defined to be changed in the given section.
Note, the same option can not be defined in the same DEFAULT section
even if that section is marked as OVERRIDE.

Allow ==, !=, <=, >=, <, and > to be used in IF statements
to compare if a section should be processed or not.
For example:
BITS := 32
DEFAULTS IF ${BITS} == 32
MIN_CONFIG = ${CONFIG_DIR}/config-32
ELSE
MIN_CONFIG = ${CONFIG_DIR}/config-64

Add IF keyword to sections within the config. Also added an ELSE
keyword that allows different config options to be set for a given
section.
For example:
TYPE := 1
STATUS := 0
DEFAULTS IF ${TYPE}
[...]
ELSE IF ${STATUS}
[...]
ELSE
[...]
The above will process the first section as $TYPE is true. If it
was false, it would process the last section as $STATUS is false.
