This patch adds __init to the ACPICA documented initializers:
acpi_initialize_tables()
acpi_initialize_subsystem()
acpi_load_tables()
acpi_enable_subsystem()
acpi_initialize_objects()
and to acpi_reallocate_root_table(), acpi_find_root_pointer() which
are also meant to be called only during initialization.
This patch adds __init to the ACPICA documented finalizer:
acpi_terminate()
as this finalizer is only called in __init function now.
This change helps to reduce source code differences between
ACPICA upstream and Linux.

Add an asmlinkage wrapper around acpi_enter_sleep_state() to prevent
an empty stub from being called by assmebly code for ACPI_REDUCED_HARDWARE
set.
As arch/x86/kernel/acpi/wakeup_xx.S is only compiled when CONFIG_ACPI=y
and there are no users of ACPI_HARDWARE_REDUCED, currently this is in
fact not a real issue, but a cleanup to reduce source code differences

Function acpi_ut_delete_caches() is meant to be used to implement
ACPI_ALLOCATE()/ACPI_FREE() mechanisms in ACPICA, so it should call
acpi_os_free() rather than ACPI_FREE(). Linux is not affected by this
issue as it uses kmem_cache instead of the ACPICA local cache, but
the change helps to reduce source code differences between Linux and
ACPICA upstream.

The new ACPICA OSL override mechanism is used to solve these issues
for the Linux OSL:
1. Linux can implement OSL using a macro.
2. Linux can implement OSL using an inlined function.
3. Linux can leave OSL not implemented for __KERNEL__ undefined code
fragments.
4. Linux can add sparse declarators (__iomem) to OSL.
5. Linux can add memory tuning declarators (__init/__exit) to OSL.
This patch also moves Linux specific OSL to aclinux.h which has not been
maintained in the ACPICA code base. Lv Zheng.
Known issue:
From ACPICA's perspective, actypes.h should be included after inclusion
of acenv.h. But currently in Linux, aclinux.h included by acenv.h has
included actypes.h to find ACPICA types for inline functions. This is a
known and existing issue and currently there is no real problem caused
by this issue for Linux kernel build. Thus this issue is not covered by
this cleanup commit.

We can't use the %pa format for these because this relates to phys_addr_t,
and dma_addr_t can be a different size. So, fix these by converting them
to %llx and casting the dma_addr_t to always be unsigned long long.
While we're here, also use %zu for size_t.

This change enables the host OS to redefine OSL prototypes found in the
acpiosxf.h file. This allows the host OS to implement OSL interfaces with
a macro or inlined function. Further, it allows the host OS to add any
additional required modifiers such as __iomem, __init, __exit, etc.,
as necessary on a per-interface basis. Enables maximum flexibility
for the OSL interfaces. Lv Zheng.

During the automatic translation of the upstream ACPICA source code
into Linux kernel source code some extra white spaces are added by
the "indent" program at the beginning of each line which is an
invocation of a macro and there is no ";" at the end of the line.
For this reason, a new mode has been added to the translation scripts
to remove the extra spaces inserted before invoking such macros and add
an empty line between the invocations of such macros (like the other
function declarations). This new mode is executed after executing
"indent" during the Linux release process. Consequently, some
existing ACPICA source code in the Linux kernel tree needs to be
adjusted to allow the new scripts to work correctly.
The affected macros and files are:
1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h):
This macro is used as a wrapper for hardware dependent APIs to offer
a stub when the reduced hardware is configured during compilation.
2. ACPI_EXPORT_SYMBOL (utglobal.c):
This macro is used by Linux to export symbols to be found by Linux
modules. All such invocations are well formatted except those
exported as global variables.
This can help to reduce the source code differences between Linux
and upstream ACPICA, and also help to automate the release process.
No functional or binary generation changes should result from it.

interfaces.
This changes can reduce source code differences between Linux and ACPICA
upstream to help improving the release automation.
The side effect of applying this patch in Linux is:
1. Some ACPICA initialization/termination APIs are no longer exported in
Linux, these include:
acpi_load_tables
acpi_initialize_subsystem
acpi_enable_subsystem
acpi_initialize_objects
acpi_terminate
2. This patch does not affect the following APIs as they are currently not
marked with ACPI_EXPORT_SYMBOL in Linux:
acpi_reallocate_root_table
acpi_initialize_tables
Such functions should not be exported as they are internal to ACPI
subsystem in Linux, and will only be invoked inside of ACPI subsystem's
initialization routines marked with __init and termination routines marked
with __exit. While on other OSPMs, such functions may still need to be
exported.
Thus this patch adds the configurability for ACPICA, so that it leaves
OSPMs to determine if the __init/__exit marked functions should be exported
or not. Lv Zheng.

We have one report of a crash in xs_tcp_setup_socket.
The call path to the crash is:
xs_tcp_setup_socket -> inet_stream_connect -> lock_sock_nested.
The 'sock' passed to that last function is NULL.
The only way I can see this happening is a concurrent call to
xs_close:
xs_close -> xs_reset_transport -> sock_release -> inet_release
inet_release sets:
sock->sk = NULL;
inet_stream_connect calls
lock_sock(sock->sk);
which gets NULL.
All calls to xs_close are protected by XPRT_LOCKED as are most
activations of the workqueue which runs xs_tcp_setup_socket.
The exception is xs_tcp_schedule_linger_timeout.
So presumably the timeout queued by the later fires exactly when some
other code runs xs_close().
To protect against this we can move the cancel_delayed_work_sync()
call from xs_destory() to xs_close().
As xs_close is never called from the worker scheduled on
->connect_worker, this can never deadlock.
