ACPICA: fix -Wfallthrough
ACPICA commit 4b9135f5774caa796ddf826448811e8e7f08ef2f
GCC 7.1 gained -Wimplicit-fallthrough to warn on implicit fallthrough, as well as __attribute__((__fallthrough__)) and comments to explicitly denote that cases of fallthrough were intentional. Clang also supports this warning and statement attribute, but not the comment form.
Robert Moore provides additional context about the lint comments being removed. They were for "an old version of PC-Lint, which we don't use anymore." Drop those.
This will help us enable -Wimplicit-fallthrough throughout the Linux kernel.

ACPICA: Add support for using logical addresses of GPE blocks
The logical address of every GPE block in system memory must be known before passing it to acpi_ev_initialize_gpe_block(), because memory cannot be mapped on the fly from an interrupt handler. Accordingly, the host OS must map every GPE block in system memory upfront and it can store the logical addresses of GPE blocks for future use.
If these logical addresses were known to ACPICA, it could use them instead of the corresponding physical addresses of GPE block for GPE register accesses and the memory mapping lookups carried out by acpi_os_read_memory() and acpi_os_write_memory() on every attempt to access a GPE register would not be necessary any more.
To allow that to happen, introduce the ACPI_GPE_USE_LOGICAL_ADDRESSES symbol to indicate whether or not the host OS wants ACPICA to use the logical addresses of GPE registers in system memory directly (which is the case if this symbol is defined). Moreover, conditional on whether ACPI_GPE_USE_LOGICAL_ADDRESSES is defined, introduce two new global variables for storing the logical addresses of the FADT GPE blocks 0 and 1, respectively, acpi_gbl_xgpe0_block_logical_address and acpi_gbl_xgpe1_block_logical_address, make acpi_ev_gpe_initialize() pass their values instead of the physical addresses of the GPE blocks in question to acpi_ev_create_gpe_block() and modify acpi_hw_gpe_read() and acpi_hw_gpe_write() to access memory directly via the addresses stored in the struct acpi_gpe_address objects, which are expected to be the logical addresses of GPE registers if ACPI_GPE_USE_LOGICAL_ADDRESSES is defined.
With the above changes in place, a host OS wanting ACPICA to access GPE registers directly through their logical addresses needs to define the ACPI_GPE_USE_LOGICAL_ADDRESSES symbol and make sure that the logical addresses of the FADT GPE blocks 0 and 1 are stored in acpi_gbl_xgpe0_block_logical_address and acpi_gbl_xgpe1_block_logical_address, respectively, prior to calling acpi_ev_gpe_initialize().
[If such a host OS also uses acpi_install_gpe_block() to add non-FADT GPE register blocks located in system memory, it must pass their logical addresses instead of their physical addresses to this function.]

ACPICA: Introduce acpi_hw_gpe_read() and acpi_hw_gpe_write()
Now that GPE blocks are validated at the initialization time, accesses to GPE registers can be made more straightforward by ommitting all of the redundant checks in acpi_hw_read() and acpi_hw_write() and only invoking the OS-provided helper for the given type of access (read or write) and the address space holding these registers.
For this reason, introduce simplified routines for accessing GPE registers, acpi_hw_gpe_read() and acpi_hw_gpe_write(), designed in accordance with the above observation, and modify all of the code accessing GPE registers to use them instead of acpi_hw_read() and acpi_hw_write(), respectively.

ACPICA: Allow acpi_any_gpe_status_set() to skip one GPE
The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring.
For this reason, redefine acpi_any_gpe_status_set() to take the number of a GPE to skip as an argument.

ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume
Unconditionally clearing ACPI IRQs during suspend/resume can lead to unexpected IRQ losts. This patch fixes this issue by removing such IRQ clearing code.
If this patch triggers regression, the regression should be in the GPE handlers that cannot correctly determine some spurious triggered events as no-ops. Please report any regression related to this commit to the ACPI component on kernel bugzilla. Lv Zheng.

ACPICA: Events: Introduce acpi_mask_gpe() to implement GPE masking mechanism
ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14
There is a facility in Linux, developers can control the enabling/disabling of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for debugging purposes.
But many users expect to use this facility to implement quirks to mask a specific GPE when there is a gap in Linux causing this GPE to flood. This is not working correctly because currently this facility invokes enabling/disabling counting based GPE driver APIs: acpi_enable_gpe()/acpi_disable_gpe() and the GPE drivers can still affect the count to mess up the GPE masking purposes.
However, most of the IRQ chip designs allow masking/unmasking IRQs via a masking bit which is different from the enabled bit to achieve the same purpose. But the GPE hardware doesn't contain such a feature, this brings the trouble.
In this patch, we introduce a software mechanism to implement the GPE masking feature, and acpi_mask_gpe() are provided to the OSPMs to mask/unmask GPEs in the above mentioned situation instead of acpi_enable_gpe()/acpi_disable_gpe(). ACPICA BZ 1102. Lv Zheng.

ACPICA: Divergence: remove unwanted spaces for typedef
ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f
This patch removes unwanted spaces for typedef. This solution doesn't cover function types.
Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

The patch reduces source code differences between the Linux kernel and the ACPICA upstream so that the linuxized ACPICA 20151218 release can be applied with reduced human intervention.
The pscode.c has already been out of sync for months, and it becomes more and more difficult to merge pscode.c changes, so instead of update the affected lines of pscode.c, this patch synchronizes entire pscode.c file.

ACPICA: Store GPE register enable masks upfront
It is reported that ACPI interrupts do not work any more on Dell Latitude D600 after commit c50f13c672df (ACPICA: Save current masks of enabled GPEs after enable register writes). The problem turns out to be related to the fact that the enable_mask and enable_for_run GPE bit masks are not in sync (in the absence of any system suspend/resume events) for at least one GPE register on that machine.
Address this problem by writing the enable_for_run mask into enable_mask as soon as enable_for_run is updated instead of doing that only after the subsequent register write has succeeded. For consistency, update acpi_hw_gpe_enable_write() to store the bit mask to be written into the GPE register in enable_mask unconditionally before the write.
Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after that, drop it along with the symbols depending on it.

ACPICA: Events: Add support to return both enable/status register values for GPE and fixed event.
ACPICA commit e25d791e4b3d5b9f4ead298269610cb05f89749a
There is a facility in Linux, developers can obtain GPE and fixed event status via /sys/firmware/interrupts/. This is implemented using acpi_get_event_status() and acpi_get_gpe_status(). Recently while debugging some GPE race issues, it is found that the facility is lacking in the ability to obtain real hardware register values, the confusing information makes debugging difficult.
This patch modifies acpi_get_gpe_status() to return EN register values to fix this gap. Then flags returned from acpi_get_event_status() and acpi_get_gpe_status() are also cleaned up to reflect this change.
The old ACPI_EVENT_FLAG_SET is carefully kept to avoid regressions. It can be deleted after we can make sure all its references are removed from OSPM code. Lv Zheng.
