(__x86_64__ || __i386__) to fix building it on other architectures.

Make perf build for x86 once the UAPI disintegration patches for that arch
have been applied by adding the appropriate -I flags - in the right order -
and then converting some #includes that use ../.. notation to find main kernel
headerfiles to use <asm/foo.h> and <linux/foo.h> instead.
Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include.
This makes sure we get the userspace version of the pt_regs struct. Ideally,
we wouldn't have the latter -I flag at all, but unfortunately we want
asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI -
at least not for x86. I wonder if the bits outside of the __KERNEL__ guards
*should* be transferred there.
I note also that perf seems to do its dependency handling manually by listing
all the header files it might want to use in LIB_H in the Makefile. Can this
be changed to use -MD?
Note that to do make this work, we need to export and UAPI disintegrate
linux/hw_breakpoint.h, which I think should've been exported previously so that
perf can access the bits. We have to do this in the same patch to maintain
bisectability.

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.
To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).
For example, take perf. This is found in tools/perf/. Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where
we run the build from, we see:
make run in dir $(OUTPUT) dir
======================= ==================
linux ~/zebra/tools/perf/
linux/tools ~/zebra/perf/
linux/tools/perf ~/zebra/
and if O= is not set, we get:
make run in dir $(OUTPUT) dir
======================= ==================
linux linux/tools/perf/
linux/tools linux/tools/perf/
linux/tools/perf linux/tools/perf/
The output directories are created by the descend function if they don't
already exist.

Define a Makefile function that can be called with $(call ...) to wrap
the subdir make invocations in tools/Makefile.
This will allow us in the next patch to insert bits in there to honour
O= flags when called from the top-level Makefile.

This was found during chasing down the header output regression. The
strbuf_addf() was checking buffer length with a result of vscnprintf()
which cannot be greater than that of strbuf_avail().
Since numa topology and pmu mapping info in header were converted to use
strbuf, it sometimes caused uninteresting behaviors with the broken
strbuf.
Fix it by using vsnprintf() which returns desired output string length
regardless of the available buffer size and grow the buffer if needed.

Revert commit 03a7beb55b9f ("epoll: support for disabling items, and a
self-test app") pending resolution of the issues identified by Michael
Kerrisk, copied below.
We'll revisit this for 3.8.
: I've taken a look at this patch as it currently stands in 3.7-rc1, and
: done a bit of testing. (By the way, the test program
: tools/testing/selftests/epoll/test_epoll.c does not compile...)
:
: There are one or two places where the behavior seems a little strange,
: so I have a question or two at the end of this mail. But other than
: that, I want to check my understanding so that the interface can be
: correctly documented.
:
: Just to go though my understanding, the problem is the following
: scenario in a multithreaded application:
:
: 1. Multiple threads are performing epoll_wait() operations,
: and maintaining a user-space cache that contains information
: corresponding to each file descriptor being monitored by
: epoll_wait().
:
: 2. At some point, a thread wants to delete (EPOLL_CTL_DEL)
: a file descriptor from the epoll interest list, and
: delete the corresponding record from the user-space cache.
:
: 3. The problem with (2) is that some other thread may have
: previously done an epoll_wait() that retrieved information
: about the fd in question, and may be in the middle of using
: information in the cache that relates to that fd. Thus,
: there is a potential race.
:
: 4. The race can't solved purely in user space, because doing
: so would require applying a mutex across the epoll_wait()
: call, which would of course blow thread concurrency.
:
: Right?
:
: Your solution is the EPOLL_CTL_DISABLE operation. I want to
: confirm my understanding about how to use this flag, since
: the description that has accompanied the patches so far
: has been a bit sparse
:
: 0. In the scenario you're concerned about, deleting a file
: descriptor means (safely) doing the following:
: (a) Deleting the file descriptor from the epoll interest list
: using EPOLL_CTL_DEL
: (b) Deleting the corresponding record in the user-space cache
:
: 1. It's only meaningful to use this EPOLL_CTL_DISABLE in
: conjunction with EPOLLONESHOT.
:
: 2. Using EPOLL_CTL_DISABLE without using EPOLLONESHOT in
: conjunction is a logical error.
:
: 3. The correct way to code multithreaded applications using
: EPOLL_CTL_DISABLE and EPOLLONESHOT is as follows:
:
: a. All EPOLL_CTL_ADD and EPOLL_CTL_MOD operations should
: should EPOLLONESHOT.
:
: b. When a thread wants to delete a file descriptor, it
: should do the following:
:
: [1] Call epoll_ctl(EPOLL_CTL_DISABLE)
: [2] If the return status from epoll_ctl(EPOLL_CTL_DISABLE)
: was zero, then the file descriptor can be safely
: deleted by the thread that made this call.
: [3] If the epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY,
: then the descriptor is in use. In this case, the calling
: thread should set a flag in the user-space cache to
: indicate that the thread that is using the descriptor
: should perform the deletion operation.
:
: Is all of the above correct?
:
: The implementation depends on checking on whether
: (events & ~EP_PRIVATE_BITS) == 0
: This replies on the fact that EPOLL_CTL_AD and EPOLL_CTL_MOD always
: set EPOLLHUP and EPOLLERR in the 'events' mask, and EPOLLONESHOT
: causes those flags (as well as all others in ~EP_PRIVATE_BITS) to be
: cleared.
:
: A corollary to the previous paragraph is that using EPOLL_CTL_DISABLE
: is only useful in conjunction with EPOLLONESHOT. However, as things
: stand, one can use EPOLL_CTL_DISABLE on a file descriptor that does
: not have EPOLLONESHOT set in 'events' This results in the following
: (slightly surprising) behavior:
:
: (a) The first call to epoll_ctl(EPOLL_CTL_DISABLE) returns 0
: (the indicator that the file descriptor can be safely deleted).
: (b) The next call to epoll_ctl(EPOLL_CTL_DISABLE) fails with EBUSY.
:
: This doesn't seem particularly useful, and in fact is probably an
: indication that the user made a logic error: they should only be using
: epoll_ctl(EPOLL_CTL_DISABLE) on a file descriptor for which
: EPOLLONESHOT was set in 'events'. If that is correct, then would it
: not make sense to return an error to user space for this case?

Pull ktest confusion fix from Steven Rostedt:
"With the v3.7-rc2 kernel, the network cards on my target boxes were
not being brought up.
I found that the modules for the network was not being installed.
This was due to the config CONFIG_MODULES_USE_ELF_RELA that came
before CONFIG_MODULES, and confused ktest in thinking that
CONFIG_MODULES=y was not found.
Ktest needs to test all configs and not just stop if something starts
with CONFIG_MODULES."

In order to decide if ktest should bother installing modules on the
target box, it checks if the config file has CONFIG_MODULES=y. But it
also checks if the '=y' part exists. It only will install modules if the
config exists and is set with '=y'. But as the regex that was used
tests:
/^CONFIG_MODULES(=y)?/
this will also match:
CONFIG_MODULES_USE_ELF_RELA
as the '=y' part was optional and it did not test the rest of the line.
When this happens, ktest will stop checking the rest of the configs but
it will also think that no modules are needed to be installed. What it
should do is only jump out of the loop if it actually found a
CONFIG_MODULES that is set to true.
Otherwise, ktest wont install the necessary modules needed for proper
booting of the test target.

Latest Linus head run of "make selftests" in the tools directory failed
with references to undefined variables. Reference was to
'write_thread_data' which is the name of a struct that is being used, not
the variable itself. Change reference so it points to the variable.

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.
To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).
For example, take perf. This is found in tools/perf/. Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where
we run the build from, we see:
make run in dir $(OUTPUT) dir
======================= ==================
linux ~/zebra/tools/perf/
linux/tools ~/zebra/perf/
linux/tools/perf ~/zebra/
and if O= is not set, we get:
make run in dir $(OUTPUT) dir
======================= ==================
linux linux/tools/perf/
linux/tools linux/tools/perf/
linux/tools/perf linux/tools/perf/
The output directories are created by the descend function if they don't
already exist.

Currently the record command sets all events initially as disabled.
There's non conditional perf_evlist__enable call, that enables all
events before we exec tracee program. That actually screws whole
enable_on_exec logic, because the event is enabled before the traced
program got executed.
What we actually want is:
1) For any type of traced program:
- all independent events and group leaders are disabled
- all group members are enabled
Group members are ruled by group leaders. They need to
be enabled, because the group scheduling relies on that.
2) For traced programs executed by perf:
- all independent events and group leaders have
enable_on_exec set
- we don't specifically enable or disable any event during
the record command
Independent events and group leaders are initially disabled
and get enabled by exec. Group members are ruled by group
leaders as stated in 1).
3) For traced programs attached by perf (pid/tid):
- we specifically enable or disable all events during
the record command
When attaching events to already running traced we
enable/disable events specifically, as there's no
initial traced exec call.
Fixing appropriate perf_event_attr test case to cover this change.

Fixing events attributes for groups defined via '{}'.
Currently 'enable_on_exec' attribute in record command and both
'disabled ' and 'enable_on_exec' attributes in stat command are set
based on the 'group' option. This eliminates proper setup for '{}'
defined groups as they don't set 'group' option.
Making above attributes values based on the 'evsel->leader' as this is
common to both group definition.
Moving perf_evlist__set_leader call within builtin-record ahead
perf_evlist__config_attrs call, because the latter needs possible group
leader links in place.
