thread__find_addr_map() falls back to trying the kernel maps if the
address is negative and is not found in userspace maps. As commented in
the code, the kernel maps must be "loaded" before use. This patch
ensures that happens under the fallback condition also.

On s390, the vmexit event has a tree-like structure: between
exit_event_begin and exit_event_end several other events may happen and
with each of them refining the previous ones.
This patch adds a decoder for such events to the generic code and also
the files <asm/kvm_perf.h> and kvm-stat.c for s390.
Commands 'perf kvm stat record', 'report' and 'live' are supported.

Current code skips output of the x86 specific HLT event in order to
avoid flooding the output with enabled --duration option. The events to
be skipped should be architecture dependent, though.
Let's add an architecture specific array of events to be skipped and
introduce a skip_event() function checking against that array.

Parts of a 'perf kvm stat' code make sense only for x86.
Let's move this code into the arch/x86/kvm-stat.c file and add
util/kvm-stat.h for generic structure definitions.
Add a global array 'kvm_reg_events_ops' for accessing the arch-specific
'kvm_events_ops' from generic code.
Since the several global arrays (i.e. 'kvm_events_tp') have been moved
to arch/*, we can not know their sizes and use them directly in
builtin-kvm.c. This patch fixes that problem by adding trimming NULL
element to each array and changing the behavior of their handlers in
generic code.

Currently perf-kvm uses string literals for kvm event names, but it
works only for x86, because other architectures may have other names for
those events.
To reduce dependence on architecture, we add <asm/kvm_perf.h> file with
defines for:
- kvm_entry and kvm_exit events,
- exit reason field name in kvm_exit event,
- length of exit reasons strings,
- vcpu_id field name in kvm trace events,
and replace literals in perf-kvm.

The perf_kvm_stat struct keeps the size of a table of exit reasons in
the field 'exit_reasons_size'.
The field is initialized and then used by get_exit_reason() for serial
access to the table, so that the calling function does not actually need
to know table size.
Usage of tables with 'end of sequence' marker simplifies the
get_exit_reason() function.
Also the patch introduces a define_exit_reasons_table, which makes it
easier to define new tables.

Right now its just a prep patch so that we can have where to update
ui_browser->rows when introducing the column headers line, that will be
togglable, so we need to update it everytime we refresh the dimensions
of the browser.

That will allow us to add a row offset to open up space for the column
headers.

Some browsers, like the hist_browser, may want to be notified everytime
a refresh_dimensions is needed, so that it can reset ui_browser->rows,
for instance, or do some other related reaction to screen resizings.

The ui_browser->height is about the whole browser "window", including
any header, status lines or any other space needed for some "Yes", "No",
etc buttons a descendent browser, like hist_browser, may have.
Since the navigation is done mostly on the ui_browser methods, it needs
to know how many rows are on the screen, while details about what other
components are, say, if a header (that may be composed of multiple
lines, etc) is present.
Besides this we'll need to add a ui_browser->refresh_dimensions() hook
so that browsers like hist_browser can update ->rows in response to
screen resizes, this will come in a follow up patch.
This patch just adds ->rows and updates it when updating ->height, keeps
using ->height for the only other widget that can come with ui_browser,
the scrollbar, that goes on using all the height on the rightmost column
in the screen, using ->rows for the keyboard navigation needs.

The tmon logging system blindly opens its log file on a static path, making it
very easy for someone to redirect that log information to inappropriate places
or overwrite other users data. Do some easy checking to make sure we're not
logging to a symlink or a file owned by another user.

A few more fixes for this RC cycle. There's a revert of a previous patch
which ended up being the wrong version, so we reverted that commit and
applied a better fix.
CPPI41 got a race condition fix which was found by Thomas Gleixner.
The MSM PHY driver got a runtime pm usage fix so that it wouldn't
kill the PHY while it was still being used.
We also have a fix for a panic caused when removing musb_am335x driver.
Other than that, a few other minor fixes.
