      This reverts commit 809d9a8f.
      
      This one isn't quite ready for prime time.  It needs more testing and
      additional feedback from the ACPI guys.

      Fix FADT parsing · 01a5bba5
      Jan Beulich authored
      The (1.0 inherited) separate length fields in the FADT are byte granular.
      Further, PM1a/b may have distinct lengths and live in distinct address spaces.
       acpi_tb_convert_fadt() should account for all of these conditions.
      
      Apart from these changes I'm puzzled by the fact that, not just for
      acpi_gbl_xpm1{a,b}_enable, acpi_hw_low_level_{read,write}() get an explicit
      size passed rather than using the size found in the passed GAS.  What happens
      on a platform that defines PM1{a,b} wider than 16 bits?  Of course,
      acpi_hw_low_level_{read,write}() at present are entirely un-prepared to deal
      with sizes other than 8, 16, or 32, not to speak of a non-zero bit_offset or
      access_width...

      PNPACPI: add support for HP vendor-specific CCSR descriptors · 40ab4f4c
      Bjorn Helgaas authored
      The HP CCSR descriptor describes MMIO address space that should appear
      as a MEM resource.  This patch adds support for parsing these descriptors
      in the _CRS data.
      
      The visible effect of this is that these MEM resources will appear
      in /sys/devices/pnp0/.../resources, which means that "lspnp -v" will
      report it, user applications can use this to locate device CSR space,
      and kernel drivers can use the normal PNP resource accessors to
      locate them.

      PNP: convert resource options to single linked list · 1f32ca31
      Bjorn Helgaas authored
      ISAPNP, PNPBIOS, and ACPI describe the "possible resource settings" of
      a device, i.e., the possibilities an OS bus driver has when it assigns
      I/O port, MMIO, and other resources to the device.
      
      PNP used to maintain this "possible resource setting" information in
      one independent option structure and a list of dependent option
      structures for each device.  Each of these option structures had lists
      of I/O, memory, IRQ, and DMA resources, for example:
      
        dev
          independent options
            ind-io0  -> ind-io1  ...
            ind-mem0 -> ind-mem1 ...
            ...
          dependent option set 0
            dep0-io0  -> dep0-io1  ...
            dep0-mem0 -> dep0-mem1 ...
            ...
          dependent option set 1
            dep1-io0  -> dep1-io1  ...
            dep1-mem0 -> dep1-mem1 ...
            ...
          ...
      
      This data structure was designed for ISAPNP, where the OS configures
      device resource settings by writing directly to configuration
      registers.  The OS can write the registers in arbitrary order much
      like it writes PCI BARs.
      
      However, for PNPBIOS and ACPI devices, the OS uses firmware interfaces
      that perform device configuration, and it is important to pass the
      desired settings to those interfaces in the correct order.  The OS
      learns the correct order by using firmware interfaces that return the
      "current resource settings" and "possible resource settings," but the
      option structures above doesn't store the ordering information.
      
      This patch replaces the independent and dependent lists with a single
      list of options.  For example, a device might have possible resource
      settings like this:
      
        dev
          options
            ind-io0 -> dep0-io0 -> dep1->io0 -> ind-io1 ...
      
      All the possible settings are in the same list, in the order they
      come from the firmware "possible resource settings" list.  Each entry
      is tagged with an independent/dependent flag.  Dependent entries also
      have a "set number" and an optional priority value.  All dependent
      entries must be assigned from the same set.  For example, the OS can
      use all the entries from dependent set 0, or all the entries from
      dependent set 1, but it cannot mix entries from set 0 with entries
      from set 1.
      
      Prior to this patch PNP didn't keep track of the order of this list,
      and it assigned all independent options first, then all dependent
      ones.  Using the example above, that resulted in a "desired
      configuration" list like this:
      
        ind->io0 -> ind->io1 -> depN-io0 ...
      
      instead of the list the firmware expects, which looks like this:
      
        ind->io0 -> depN-io0 -> ind-io1 ...

      ISAPNP: handle independent options following dependent ones · bbe413b4
      Bjorn Helgaas authored
      The ISAPNP spec recommends that independent options precede
      dependent ones, but this is not actually required.  The current
      ISAPNP code incorrectly puts such trailing independent options
      at the end of the last dependent option list.
      
      This patch fixes that bug by resetting the current option list
      to the independent list when we see an "End Dependent Functions"
      tag.  PNPBIOS and PNPACPI handle this the same way.

      PNP: remove extra 0x100 bit from option priority · e2a1a6f1
      Bjorn Helgaas authored
      When building resource options, ISAPNP and PNPBIOS set the priority
      to something like "0x100 | PNP_RES_PRIORITY_ACCEPTABLE", but we
      immediately mask off the 0x100 again in pnp_build_option(), so that
      bit looks superfluous.

      PNP: support optional IRQ resources · d5ebde6e
      Bjorn Helgaas authored
      This patch adds an IORESOURCE_IRQ_OPTIONAL flag for use when
      assigning resources to a device.  If the flag is set and we are
      unable to assign an IRQ to the device, we can leave the IRQ
      disabled but allow the overall resource allocation to succeed.
      
      Some devices request an IRQ, but can run without an IRQ
      (possibly with degraded performance).  This flag lets us run
      the device without the IRQ instead of just leaving the
      device disabled.
      
      This is a reimplementation of this previous change by Rene
      Herman <rene.herman@gmail.com>:
          http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=3b73a223661ed137c5d3d2635f954382e94f5a43
      
      I reimplemented this for two reasons:
          - to prepare for converting all resource options into a single linked
            list, as opposed to the per-resource-type lists we have now, and
          - to preserve the order and number of resource options.
      
      In PNPBIOS and ACPI, we configure a device by giving firmware a
      list of resource assignments.  It is important that this list
      has exactly the same number of resources, in the same order,
      as the "template" list we got from the firmware in the first
      place.
      
      The problem of a sound card MPU401 being left disabled for want of
      an IRQ was reported by Uwe Bugla <uwe.bugla@gmx.de>.

      PNPACPI: ignore _PRS interrupt numbers larger than PNP_IRQ_NR · fe2cf598
      Bjorn Helgaas authored
      ACPI Extended Interrupt Descriptors can encode 32-bit interrupt
      numbers, so an interrupt number may exceed the size of the bitmap
      we use to track possible IRQ settings.
      
      To avoid corrupting memory, complain and ignore too-large interrupt
      numbers.
      
      There's similar code in pnpacpi_parse_irq_option(), but I didn't
      change that because the small IRQ descriptor can only encode
      IRQs 0-15, which do not exceed bitmap size.
      
      In the future, we could handle IRQ numbers greater than PNP_IRQ_NR
      by replacing the bitmap with a table or list.

      PNP: centralize resource option allocations · c227536b

      This patch moves all the option allocations (pnp_mem, pnp_port, etc)

      will make it easier to rework the option data structures.
      
      The non-trivial part of this patch is the IRQ handling.  The backends
      have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass
      a pointer to pnp_register_irq_resource().
