On some systems, hot-plug tests could hang forever waiting for cpu and
memory to be ready to be offlined. A special hot-plug target is created
to run full range of hot-plug tests. In default mode, hot-plug tests run
in safe mode with a limited scope. In limited mode, cpu-hotplug test is
run on a single cpu as opposed to all hotplug capable cpus, and memory
hotplug test is run on 2% of hotplug capable memory instead of 10%. In
addition to the above change, cpu-hotplug is chnged to change processor
affinity to cpu 0 so it doesn't impact itself while the test runs.

This patch uses abstract file IO and acpi_log_error() APIs to enhance
cm_get_file_size() so that applications that invoke this API could have
portability improved.
With actual references added to abstract file IO and acpi_log_error(), the
applications need to link oslibcfs.o, utdebug.o, utexcep.o, utmath.o,
utprint.o and utxferror.o.
It is also required to add acpi_os_initialize() invocations if an
application starts to use acpi_log_error().
acpidump has already invoked acpi_os_initialize() in this way. Lv Zheng.

acpi_os_printf() to improve portability
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.
acpidump has already invoked acpi_os_initialize() in this way. Lv Zheng.

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 adds portable file IO to generic OSL to improve the portability

A portable application may use different file IO interfaces than the
standard C library ones. This patch thus introduces an abstract file IO
layer into the generic OSL.
Note that this patch does not introduce users of such interfaces, further
patches should introduce users one by one carefully with build tests
performed. 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.

acpi_ut_init_global() from utglobal.c to utinit.c
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.

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.

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

Commit fb9edbe984 shortened held_lock->check from a 2-bit field
to a 1-bit field.
Make liblockdep compatible with the new definition by passing check=1
to lock_acquire() calls, rather than the old value check=2 (which
inadvertently disabled checks by overflowing to 0).
Without this fix, several of the test cases in liblockdep run_tests.sh
were failing.

Comparison of a boolean value (!__init_state) with a value of 2 (done)
as currently happens in the code is unlikely to succeed and causes
repeated initialization of the pthread function pointers.
Instead, remove boolean comparison so that we would initialize said
function pointers only once.

This requires some more work so that we can really just use the width of
current entries when we want to partition the screen.
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.

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.
