ACPI: property: Make the ACPI graph API private
The fwnode graph API is preferred over the ACPI graph API. Therefore make the ACPI graph API private, and use it as a back-end for the fwnode graph API only. Unused functionality is removed while the functionality actually used remains the same. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Rafael J.

ACPI: Convert ACPI reference args to generic fwnode reference args
Convert all users of struct acpi_reference_args to more generic
fwnode_reference_args. This will
1) avoid an ACPI specific references to device nodes with integer
arguments as well as
2) allow making references to nodes other than device nodes in ACPI.
As a by-product, convert the fwnode interger arguments to u64. The
arguments were 64-bit integers on ACPI but the fwnode arguments were
just 32-bit.

acpi: Add helper for deactivating memory region
Sometimes memory resource may be overlapping with
SystemMemory Operation Region by design, for example if the
memory region is used as a mailbox for communication with a
firmware in the system. One occasion of such mailboxes is
USB Type-C Connector System Software Interface (UCSI).
With regions like that, it is important that the driver is
able to map the memory with the requirements it has. For
example, the driver should be allowed to map the memory as
non-cached memory. However, if the operation region has been
accessed before the driver has mapped the memory, the memory
has been marked as write-back by the time the driver is
loaded. That means the driver will fail to map the memory
if it expects non-cached memory.
To work around the problem, introducing helper that the
drivers can use to temporarily deactivate (unmap)
SystemMemory Operation Regions that overlap with their
IO memory.

arm64 updates for 4.18:
- Spectre v4 mitigation (Speculative Store Bypass Disable) support for
arm64 using SMC firmware call to set a hardware chicken bit
- ACPI PPTT (Processor Properties Topology Table) parsing support and
enable the feature for arm64
- Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
primary motivation is Scalable Vector Extensions which requires more
space on the signal frame than the currently defined MINSIGSTKSZ
- ARM perf patches: allow building arm-cci as module, demote dev_warn()
to dev_dbg() in arm-ccn event_init(), miscellaneous cleanups
- cmpwait() WFE optimisation to avoid some spurious wakeups
- L1_CACHE_BYTES reverted back to 64 (for performance reasons that have
to do with some network allocations) while keeping ARCH_DMA_MINALIGN
to 128. cache_line_size() returns the actual hardware Cache Writeback
Granule
- Turn LSE atomics on by default in Kconfig
- Kernel fault reporting tidying
- Some #include and miscellaneous cleanups

ACPI/PPTT: Add Processor Properties Topology Table parsing
ACPI 6.2 adds a new table, which describes how processing units are related to each other in tree like fashion. Caches are also sprinkled throughout the tree and describe the properties of the caches in relation to other caches and processing units. Add the code to parse the cache hierarchy and report the total number of levels of cache for a given core using acpi_find_last_cache_level() as well as fill out the individual cores cache information with cache_setup_acpi() once the cpu_cacheinfo structure has been populated by the arch specific code. An additional patch later in the set adds the ability to report peers in the topology using find_acpi_cpu_topology() to report a unique ID for each processing unit at a given level in the tree. These unique id's can then be used to match related processing units which exist as threads, within a given package, etc. Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Tested-by: Vijaya Kumar K <vkilari@codeaurora.org> Tested-by: Xiongfeng Wang <wangxiongfeng2@huawei.com> Tested-by: Tomasz Nowicki <Tomasz.Nowicki@cavium.com> Acked-by: Sudeep Holla <sudeep.holla@arm.com> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Rafael J.

PM / Domains: Allow a better error handling of dev_pm_domain_attach()
The callers of dev_pm_domain_attach() currently checks the returned error code for -EPROBE_DEFER and needs to ignore other error codes. This is an unnecessary limitation, which also leads to a rather strange behaviour in the error path. Address this limitation, by changing the return codes from acpi_dev_pm_attach() and genpd_dev_pm_attach(). More precisely, let them return 0, when no PM domain is needed for the device and then return 1, in case the device was successfully attached to its PM domain. In this way, dev_pm_domain_attach(), gets a better understanding of what happens in the attach attempts and also allowing its caller to better act on real errors codes.

PCI/ACPI: Request LTR control from platform before using it
Per the PCI Firmware spec r3.2, sec 4.5, an ACPI-based OS should use _OSC to request control of Latency Tolerance Reporting (LTR) before using it. Request control of LTR, and if the platform does not grant control, don't use it. N.B. If the hardware supports LTR and the ASPM L1.2 substate but the BIOS doesn't support LTR in _OSC, we previously would enable ASPM L1.2. This patch will prevent us from enabling ASPM L1.2 in that case. It does not prevent us from enabling PCI-PM L1.2, since that doesn't depend on LTR. See PCIe r40, sec 5.5.1, for the L1 PM substate entry conditions. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

ACPI: SPCR: Make SPCR available to x86
SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup an early console. General fixes include updating Documentation & Kconfig (for x86), updating comments, and changing parse_spcr() to acpi_parse_spcr(), and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be more descriptive. On x86, many systems have a valid SPCR table but the table version is not 2 so the table version check must be a warning. On ARM64 when the kernel parameter earlycon is used both the early console and console are enabled. On x86, only the earlycon should be enabled by by default. Modify acpi_parse_spcr() to allow options for initializing the early console and console separately.

The is the bulk of GPIO changes for the v4.16 kernel cycle.
Core changes:
- Disallow open drain and open source flags to be set
simultaneously. This doesn't make electrical sense, and would
the hardware actually respond to this setting, the result
would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks.
The quirks are there to deal with broken ACPI tables centrally
instead of pushing the work to individual drivers. In the world
of BIOS writers, the ACPI tables are perfect. Until they find a
mistake in it. When such a mistake is found, we can patch it
with a quirk. It should never happen, the problem is that it
happens. So we accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from
reading the device. This was causing bad things for drivers
that can't read status on all its pins. It is only affecting
debugfs information quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use
GPIO descriptors by implementing some quirks in the device tree
GPIO parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver
used for test and verification.
- Moved the AXP209 driver over to pin control since it gained a
pin control back-end. These patches will appear (with the same
hashes) in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors.
This is merged here since the W1 maintainers send very few
pull requests and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just
use <linux/gpio/driver.h> as appropriate.

Power management updates for v4.16-rc1
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver
PM flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of
genpd (Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the
ACPI core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal
and clean up the governor management code in the cpufreq core
(Rafael Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id
from the PSCI driver and drop dependency on arm_big_little from
the SCPI cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott).

Pull power management updates from Rafael Wysocki:
"This includes some infrastructure changes in the PM core, mostly
related to integration between runtime PM and system-wide suspend and
hibernation, plus some driver changes depending on them and fixes for
issues in that area which have become quite apparent recently.
Also included are changes making more x86-based systems use the Low
Power Sleep S0 _DSM interface by default, which turned out to be
necessary to handle power button wakeups from suspend-to-idle on
Surface Pro3.
On the cpufreq front we have fixes and cleanups in the core, some new
hardware support, driver updates and the removal of some unused code
from the CPU cooling thermal driver.
Apart from this, the Operating Performance Points (OPP) framework is
prepared to be used with power domains in the future and there is a
usual bunch of assorted fixes and cleanups.
Specifics:
- Define a PM driver flag allowing drivers to request that their
devices be left in suspend after system-wide transitions to the
working state if possible and add support for it to the PCI bus
type and the ACPI PM domain (Rafael Wysocki).
- Make the PM core carry out optimizations for devices with driver PM
flags set in some cases and make a few drivers set those flags
(Rafael Wysocki).
- Fix and clean up wrapper routines allowing runtime PM device
callbacks to be re-used for system-wide PM, change the generic
power domains (genpd) framework to stop using those routines
incorrectly and fix up a driver depending on that behavior of genpd
(Rafael Wysocki, Ulf Hansson, Geert Uytterhoeven).
- Fix and clean up the PM core's device wakeup framework and
re-factor system-wide PM core code related to device wakeup
(Rafael Wysocki, Ulf Hansson, Brian Norris).
- Make more x86-based systems use the Low Power Sleep S0 _DSM
interface by default (to fix power button wakeup from
suspend-to-idle on Surface Pro3) and add a kernel command line
switch to tell it to ignore the system sleep blacklist in the ACPI
core (Rafael Wysocki).
- Fix a race condition related to cpufreq governor module removal and
clean up the governor management code in the cpufreq core (Rafael
Wysocki).
- Drop the unused generic code related to the handling of the static
power energy usage model in the CPU cooling thermal driver along
with the corresponding documentation (Viresh Kumar).
- Add mt2712 support to the Mediatek cpufreq driver (Andrew-sh
Cheng).
- Add a new operating point to the imx6ul and imx6q cpufreq drivers
and switch the latter to using clk_bulk_get() (Anson Huang, Dong
Aisheng).
- Add support for multiple regulators to the TI cpufreq driver along
with a new DT binding related to that and clean up that driver
somewhat (Dave Gerlach).
- Fix a powernv cpufreq driver regression leading to incorrect CPU
frequency reporting, fix that driver to deal with non-continguous
P-states correctly and clean it up (Gautham Shenoy, Shilpasri
Bhat).
- Add support for frequency scaling on Armada 37xx SoCs through the
generic DT cpufreq driver (Gregory CLEMENT).
- Fix error code paths in the mvebu cpufreq driver (Gregory CLEMENT).
- Fix a transition delay setting regression in the longhaul cpufreq
driver (Viresh Kumar).
- Add Skylake X (server) support to the intel_pstate cpufreq driver
and clean up that driver somewhat (Srinivas Pandruvada).
- Clean up the cpufreq statistics collection code (Viresh Kumar).
- Drop cluster terminology and dependency on physical_package_id from
the PSCI driver and drop dependency on arm_big_little from the SCPI
cpufreq driver (Sudeep Holla).
- Add support for system-wide suspend and resume to the RAPL power
capping driver and drop a redundant semicolon from it (Zhen Han,
Luis de Bethencourt).
- Make SPI domain validation (in the SCSI SPI transport driver) and
system-wide suspend mutually exclusive as they rely on the same
underlying mechanism and cannot be carried out at the same time
(Bart Van Assche).
- Fix the computation of the amount of memory to preallocate in the
hibernation core and clean up one function in there (Rainer Fiebig,
Kyungsik Lee).
- Prepare the Operating Performance Points (OPP) framework for being
used with power domains and clean up one function in it (Viresh
Kumar, Wei Yongjun).
- Clean up the generic sysfs interface for device PM (Andy
Shevchenko).
- Fix several minor issues in power management frameworks and clean
them up a bit (Arvind Yadav, Bjorn Andersson, Geert Uytterhoeven,
Gustavo Silva, Julia Lawall, Luis de Bethencourt, Paul Gortmaker,
Sergey Senozhatsky, gaurav jindal).
- Make it easier to disable PM via Kconfig (Mark Brown).
- Clean up the cpupower and intel_pstate_tracer utilities (Doug
Smythies, Laura Abbott)"

device property: Introduce fwnode_irq_get()
Until now there were two very similar functions allowing to get Linux IRQ number from ACPI handle (acpi_irq_get()) and OF node (of_irq_get()). The first one appeared to be used only as a subroutine of platform_irq_get(), which (in the generic code) limited IRQ obtaining from _CRS method only to nodes associated to kernel's struct platform_device. This patch introduces a new helper routine - fwnode_irq_get(), which allows to get the IRQ number directly from the fwnode to be used as common for OF/ACPI worlds. It is usable not only for the parents fwnodes, but also for the child nodes comprising their own _CRS methods with interrupts description. In order to be able o satisfy compilation with !CONFIG_ACPI and also simplify the new code, introduce a helper macro (ACPI_HANDLE_FWNODE), with which it is possible to reach an ACPI handle directly from its fwnode.

ACPI: utils: Introduce acpi_dev_get_first_match_name()
Sometimes the user wants to have device name of the match rather than just checking if device present or not. To make life easier for such users introduce acpi_dev_get_first_match_name() helper based on code for acpi_dev_present(). For example, GPIO driver for Intel Merrifield needs to know the device name of pin control to be able to apply GPIO mapping table to the proper device. To be more consistent with the purpose rename struct acpi_dev_present_info -> struct acpi_dev_match_info acpi_dev_present_cb() -> acpi_dev_match_cb() in the utils.c file.

ACPI / PM: Make it possible to ignore the system sleep blacklist
The ACPI code supporting system transitions to sleep states uses
an internal blacklist to apply special handling to some machines
reported to behave incorrectly in some ways.
However, some entries of that blacklist cover problematic as well as
non-problematic systems, so give the users of the latter a chance to
ignore the blacklist and run their systems in the default way by
adding acpi_sleep=nobl to the kernel command line.
For example, that allows the users of Dell XPS13 9360 systems not
affected by the issue that caused the blacklist entry for this
machine to be added by commit

ACPI / PM: Take SMART_SUSPEND driver flag into account
Make the ACPI PM domain take DPM_FLAG_SMART_SUSPEND into account in its system suspend callbacks. [Note that the pm_runtime_suspended() check in acpi_dev_needs_resume() is an optimization, because if is not passed, all of the subsequent checks may be skipped and some of them are much more overhead in general.] Also use the observation that if the device is in runtime suspend at the beginning of the "late" phase of a system-wide suspend-like transition, its state cannot change going forward (runtime PM is disabled for it at that time) until the transition is over and the subsequent system-wide PM callbacks should be skipped for it (as they generally assume the device to not be suspended), so add checks for that in acpi_subsys_suspend_late/noirq() and acpi_subsys_freeze_late/noirq(). Moreover, if acpi_subsys_resume_noirq() is called during the subsequent system-wide resume transition and if the device was left in runtime suspend previously, its runtime PM status needs to be changed to "active" as it is going to be put into the full-power state going forward, so add a check for that too in there. In turn, if acpi_subsys_thaw_noirq() runs after the device has been left in runtime suspend, the subsequent "thaw" callbacks need to be skipped for it (as they may not work correctly with a suspended device), so set the power.direct_complete flag for the device then to make the PM core skip those callbacks. On top of the above, make the analogous changes in the acpi_lpss driver that uses the ACPI PM domain callbacks. Signed-off-by: Rafael J.

ACPI / LPIT: Add Low Power Idle Table (LPIT) support
Add functionality to read LPIT table, which provides: - Sysfs interface to read residency counters via /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us Here the count "low_power_idle_cpu_residency_us" shows the time spent by CPU package in low power state. This is read via MSR interface, which points to MSR for PKG C10. Here the count "low_power_idle_system_residency_us" show the count the system was in low power state. This is read via MMIO interface. This is mapped to SLP_S0 residency on modern Intel systems. This residency is achieved only when CPU is in PKG C10 and all functional blocks are in low power state. It is possible that none of the above counters present or anyone of the counter present or all counters present. For example: On my Kabylake system both of the above counters present. After suspend to idle these counts updated and prints: 6916179 6998564 This counter can be read by tools like turbostat to display. Or it can be used to debug, if modern systems are reaching desired low power state. - Provides an interface to read residency counter memory address This address can be used to get the base address of PMC memory mapped IO. This is utilized by intel_pmc_core driver to print more debug information. In addition, to avoid code duplication to read iomem, removed the read of iomem from acpi_os_read_memory() in osl.c and made a common function acpi_os_read_iomem(). This new function is used for reading iomem in in both osl.c and acpi_lpit.c.

ACPI: Introduce DMA ranges parsing
Some devices have limited addressing capabilities and cannot reference the whole memory address space while carrying out DMA operations (eg some devices with bus address bits range smaller than system bus - which prevents them from using bus addresses that are otherwise valid for the system). The ACPI _DMA object allows bus devices to define the DMA window that is actually addressable by devices that sit upstream the bus, therefore providing a means to parse and initialize the devices DMA masks and addressable DMA range size. By relying on the generic ACPI kernel layer to retrieve and parse resources, introduce ACPI core code to parse the _DMA object.

tty: pl011: fix initialization order of QDF2400 E44
The work-around for Qualcomm Technologies QDF2400 Erratum 44 hinges on a
global variable defined in the pl011 driver. The ACPI SPCR parsing code
determines whether the work-around is needed, and if so, it changes the
console name from "pl011" to "qdf2400_e44". The expectation is that
the pl011 driver will implement the work-around when it sees the console
name. The global variable qdf2400_e44_present is set when that happens.
The problem is that work-around needs to be enabled when the pl011
driver probes, not when the console name is queried. However, sbsa_probe()
is called before pl011_console_match(). The work-around appeared to work
previously because the default console on QDF2400 platforms was always
ttyAMA1. The first time sbsa_probe() is called (for ttyAMA0),
qdf2400_e44_present is still false. Then pl011_console_match() is called,
and it sets qdf2400_e44_present to true. All subsequent calls to
sbsa_probe() enable the work-around.
The solution is to move the global variable into spcr.c and let the
pl011 driver query it during probe time. This works because all QDF2400
platforms require SPCR, so parse_spcr() will always be called.
pl011_console_match still checks for the "qdf2400_e44" console name,
but it doesn't do anything else special.
Fixes:

device property: Get rid of struct fwnode_handle type field
Instead of relying on the struct fwnode_handle type field, define fwnode_operations structs for all separate types of fwnodes. To find out the type, compare to the ops field to relevant ops structs. This change has two benefits: 1. it avoids adding the type field to each and every instance of struct fwnode_handle, thus saving memory and 2. makes the ops field the single factor that defines both the types of the fwnode as well as defines the implementation of its operations, decreasing the possibility of bugs when developing code dealing with fwnode internals.

Device properties framework updates for v4.13-rc1
- Rearrange the core device properties code by moving the code
specific to each supported platform configuration framework
(ACPI, DT and build-in) into a separate file (Sakari Ailus).
- Add helper functions for accessing device properties in a
firmware-agnostic way (Sakari Ailus, Kieran Bingham).

This is the bulk of GPIO changes for the v4.13 series:
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO line
may loose its state during suspend/resume of the system to save
power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.
Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.
Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.
Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.
Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.
The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO
line may loose its state during suspend/resume of the system to
save power. This is used in the Wolfson Micro Arizona driver.

device property: Move FW type specific functionality to FW specific files
The device and fwnode property API supports Devicetree, ACPI and pset
properties. The implementation of this functionality for each firmware
type was embedded in the fwnode property core. Move it out to firmware
type specific locations, making it easier to maintain.
Depends-on: ("of: Move OF property and graph API from base.c to property.c")

ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()
acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. Acked-by: Rafael J.
