      Pull ACPI and power management fixes from Rafael Wysocki:
       "These are regression fixes (ACPI hotplug, cpufreq, hibernation, ACPI
        LPSS driver), fixes for stuff that never worked correctly (ACPI GPIO
        support in some cases and a wrong sign of an error code in the ACPI
        core in one place), and one blacklist item for ACPI backlight
        handling.
      
        Specifics:
      
         - Revert of a recent hibernation core commit that introduced a NULL
           pointer dereference during resume for at least one user (Rafael J
           Wysocki).
      
         - Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable
           asynchronous PM callback execution for LPSS devices during system
           suspend/resume (introduced in 3.16) which turns out to break
           ordering expectations on some systems.  From Fu Zhonghui.
      
         - cpufreq core fix related to the handling of sysfs nodes during
           system suspend/resume that has been broken for intel_pstate since
           3.15 from Lan Tianyu.
      
         - Restore the generation of "online" uevents for ACPI container
           devices that was removed in 3.14, but some user space utilities
           turn out to need them (Rafael J Wysocki).
      
         - The cpufreq core fails to release a lock in an error code path
           after changes made in 3.14.  Fix from Prarit Bhargava.
      
         - ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO
           operation regions (which means AML using GPIOs) work correctly in
           all cases from Bob Moore and Srinivas Pandruvada.
      
         - Fix for a wrong sign of the ACPI core's create_modalias() return
           value in case of an error from Mika Westerberg.
      
         - ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu"

      Pull i2c fixes from Wolfram Sang:
       "This is probably not the kind of pull request you want to see that
        late in the cycle.  Yet, the ACPI refactorization was problematic
        again and caused another two issues which need fixing.  My holidays
        with limited internet (plus travelling) and the developer's illness
        didn't help either :(
      
        The details:
      
         - ACPI code was refactored out into a seperate file and as a
           side-effect, the i2c-core module got renamed.  Jean Delvare
           rightfully complained about the rename being problematic for
           distributions.  So, Mika and I thought the least problematic way to
           deal with it is to move all the code back into the main i2c core
           source file.  This is mainly a huge code move with some #ifdeffery
           applied.  No functional code changes.  Our personal tests and the
           testbots did not find problems.  (I was thinking about reverting,
           too, yet that would also have ~800 lines changed)
      
         - The new ACPI code also had a NULL pointer exception, thanks to
           Peter for finding and fixing it.
      
         - Mikko fixed a locking problem by decoupling clock_prepare and
           clock_enable.
      
         - Addy learnt that the datasheet was wrong and reimplemented the
           frequency setup according to the new algorithm.
      
        - Fan fixed an off-by-one error when copying data
      
        - Janusz fixed a copy'n'paste bug which gave a wrong error message
      
        - Sergei made sure that "don't touch" bits are not accessed"

      i2c: acpi: Fix NULL Pointer dereference · 0aef44e8
      Peter Hüwe authored
      If adapter->dev.parent == NULL there is a NULL pointer dereference in
      acpi_i2c_install_space_handler and acpi_i2c_remove_space_handler.
      
      This is present since introduction of this code:
      36604751 "i2c: rework kernel config I2C_ACPI" or even
      da3c6647
      
       "I2C/ACPI: Clean up I2C ACPI code and Add CONFIG_I2C_ACPI"
      
      The adapter->dev.parent == NULL case is valid for the i2c_stub,
      so loading i2c_stub with ACPI_I2C_OPREGION enabled results in an oops.
      This is also valid at least for i2c_tiny_usb and i2c_robotfuzz_osif.
      
      Fix by checking whether it is null before calling ACPI_HANDLE.

      In cases where board has below memory DT node
      
      memory{
      	device_type = "memory";
      	reg = <0x80000000 0x80000000>;
      };
      
      Check on the memory range in fdt.c will always fail because it is
      comparing MAX_PHYS_ADDR with base + size, in fact it should compare
      it with base + size - 1.
      
      This issue was originally noticed on Qualcomm IFC6410 board.
      Without this patch kernel shows up noticed unnecessary warnings
      
      [    0.000000] Machine model: Qualcomm APQ8064/IFC6410

      as a result the size get reduced to 0x7fffffff which looks wrong.
      
      This patch fixes the check involved in generating this warning and
      as a result it also fixes the wrong size calculation.

      x86/efi: Truncate 64-bit values when calling 32-bit OutputString() · 115c6628
      Matt Fleming authored
      If we're executing the 32-bit efi_char16_printk() code path (i.e.
      running on top of 32-bit firmware) we know that efi_early->text_output
      will be a 32-bit value, even though ->text_output has type u64.
      
      Unfortunately, we currently pass ->text_output directly to
      efi_early->call() so for CONFIG_X86_32 the compiler will push a 64-bit
      value onto the stack, causing the other parameters to be misaligned.
      
      The way we handle this in the rest of the EFI boot stub is to pass
      pointers as arguments to efi_early->call(), which automatically do the
      right thing (pointers are 32-bit on CONFIG_X86_32, and we simply ignore
      the upper 32-bits of the argument register if running in 64-bit mode
      with 32-bit firmware).
      
      This fixes a corruption bug when printing strings from the 32-bit EFI
      boot stub.

      ACPICA: Update to GPIO region handler interface. · 75ec6e55
      Bob Moore authored
      
      
      Changes to correct several GPIO issues:
      
      1) The update_rule in a GPIO field definition is now ignored;
      a read-modify-write operation is never performed for GPIO fields.
      (Internally, this means that the field assembly/disassembly
      code is completely bypassed for GPIO.)
      
      2) The Address parameter passed to a GPIO region handler is
      now the bit offset of the field from a previous Connection()
      operator. Thus, it becomes a "Pin Number Index" into the
      Connection() resource descriptor.
      
      3) The bit_width parameter passed to a GPIO region handler is
      now the exact bit width of the GPIO field. Thus, it can be
      interpreted as "number of pins".
      
      Overall, we can now say that the region handler interface
      to GPIO handlers is a raw "bit/pin" addressed interface, not
      a byte-addressed interface like the system_memory handler interface.

      ACPI / platform / LPSS: disable async suspend/resume of LPSS devices · 45792081
      Fu Zhonghui authored
      On some systems (Asus T100 in particular) there are strict ordering
      dependencies between LPSS devices with respect to power management
      that break if they suspend/resume asynchronously.
      
      In theory it should be possible to follow those dependencies in the
      async suspend/resume case too (the ACPI tables tell as that the
      dependencies are there), but since we're missing infrastructure
      for that at the moment, disable async suspend/resume for all of
      the LPSS devices for the time being.

       "Here is a quick pull request primarily meant to address the deconfig
        fallout from changing SCSI_NETLINK from being used via 'select' to
        being used via 'depends'.
      
        I applied a set of 5 patches written by Michal Marek, and then I
        carefully audited all of the remaining config files, basically:
      
         1) I scanned every arch config file, and if it mentioned CONFIG_INET
            or CONFIG_UNIX, I made sure it had CONFIG_NET=y
      
         2) After that, I scanned every arch config file, and if it did not
            have CONFIG_NET=y I made sure it did not reference any networking
            config options.
      
        Finally, we have some late breaking wireless fixes in here from John
        Linville and co"

      - fix BPF_LD|ABS|IND from negative offsets:
        make sure to sign extend lower 32 bits in 64-bit register
        before calling C helpers from JITed code, otherwise 'int k'
        argument of bpf_internal_load_pointer_neg_helper() function
        will be added as large unsigned integer, causing packet size
        check to trigger and abort the program.
      
        It's worth noting that JITed code for 'A = A op K' will affect
        upper 32 bits differently depending whether K is simm13 or not.
        Since small constants are sign extended, whereas large constants
        are stored in temp register and zero extended.
        That is ok and we don't have to pay a penalty of sign extension
        for every sethi, since all classic BPF instructions have 32-bit
        semantics and we only need to set correct upper bits when
        transitioning from JITed code into C.
      
      - though instructions 'A &= 0' and 'A *= 0' are odd, JIT compiler
        should not optimize them out

      For the NFC bits, Samuel says:
      
      "Hopefully not too late for a handful of NFC fixes:
      
      - 2 potential build failures for ST21NFCA and ST21NFCB, triggered by a
        depmod dependenyc cycle.
      - One potential buffer overflow in the microread driver."

      Emil Goode provides a fix for a brcmfmac off-by-one regression which
      was introduced in the 3.17 cycle.
      
      Loic Poulain fixes a polarity mismatch for a variable assignment
