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.

This patch enhances ACPI_USAGE_xxx/ACPI_OPTION macros to use portable
acpi_os_printf() so that usage functions for applications no longer rely on
the printf() API.
To use acpi_os_printf() exported by osunixxf.c as a replacement of
printf(), applications need to initialize acpi_gbl_output_file to stdout
and initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. The
latter is automatically done by ACPI_INIT_GLOBAL(), applications need to
link utglobal.o to utilize this mechanism. For GCC, assigning stdout to
acpi_gbl_output_file using ACPI_INIT_GLOBAL() is not possible as stdout is
not a constant in GCC environment. As an alternative solution, stdout
assignment has been put into acpi_os_initialize(). Thus
acpi_os_initialize() need to be invoked very early by the applications to
initialize the default output of acpi_os_printf() to keep behavior
consistency.

This patch introduces formatted printing APIs to handle ACPICA specific
formatted print requirements. Currently only specific OSPMs will use this
customized printing support, Linux kernel doesn't use these APIs at this
time. It will be enabled for Linux kernel resident ACPICA after being well
tested. So currently this patch is a no-op.
The specific formatted printing APIs are useful to ACPICA as:
1. Some portable applications do not link standard C library, so they
cannot use standard formatted print APIs directly.
2. Platform specific printing format may differ and thus not portable, for
example, u64 is %ull for Linux kernel and is %uI64 for some MSVC
versions.
3. Platform specific printing format may conflict with ACPICA's usages
while it is not possible for ACPICA developers to test their code for
all platforms. For example, developers may generate %pRxxx while Linux
kernel treats %pR as structured resource printing and decodes variable
argument as a "struct resource" pointer.
This patch solves above issues by introducing the new APIs.
Note that users of such APIs are not introduced in this patch. Users of
acpi_os_file_vprintf()/acpi_ut_file_printf() need to invoke acpi_os_initialize(),
this should be taken care by the further patches where such users are
introduced. Lv Zheng.

This patch is mainly for acpidump where there are redundant
acpi_os_printf()/acpi_os_vprintf() stubs implemented. This patch cleans up such
specific implementation by linking acpidump to osunixxf.c/oswinxf.c.
To make acpi_os_printf() exported by osunixxf.c/oswinxf.c to behave as the
old acpidump specific ones, applications need to:
1. Initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT.
This is automatically done by ACPI_INIT_GLOBAL(), applications need to
link utglobal.o to utilize this mechanism.
2. Initialize acpi_gbl_output_file to stdout.
For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL()
is not possible as stdout is not a constant in GCC environment. As an
alternative solution, stdout assignment is put into acpi_os_initialize().
Thus acpi_os_initialize() need to be invoked very early by the
applications to initialize the default output of acpi_os_printf().
This patch also releases osunixxf.c to the Linux kernel. Lv Zheng.

The utglobal.c is used to define and initialize global variables. It makes
sense if just adding utglobal.o to applications that are using such
variables. But acpi_ut_init_globals() is preventing us from doing so as
this initialization function references other components' initializations
code, which leads to the requirement that many files should also get linked
if one wants to link utglobal.o.
It is possible to just move acpi_ut_init_global() to utinit.c for
applications that require this function to link.
By linking utglobal.o, we can stop defining DEFINE_ACPI_GLOBALS for
applications (currently only acpidump is affected). Lv Zheng.

The following snippet
V = malloc(S);
if (!V) { }
sprintf(V, ...)
Can be easily changed to a one line:
if (asprintf(&V, ...) < 0) { }

cpu_isa_config() does two different things: searching for cpuid and
initializing perf_kvm_stat struct with proper parameters.
Let's move initialization to a separate function cpu_isa_init(), which
is used to initialize all possible ISAs and can be used to init
arch-depended things.

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.

kvm stat support is currently conditional on i386/x86_64. Let's abstract
this into a HAVE_KVM_STAT_SUPPORT flag, so that other architectures can
support kvm stat as well.

Looks better and avoids it moving to the end of the screen as the column

Adding ui.show-headers config file option to define if the histogram
entries headers will start visible or not.
Currently columns headers are displayed by default, following
lines in ~/.perfconfig file will disable that:
[ui]
show-headers = false
