      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.
