Len Brown 7b46ecd5fc Revert "ACPI: make some IO ports off-limits to AML"
This reverts commit 5ec5d38a1c.
because it caused spurious dmesg warmings.
We'll implement the check for off-limit ports

Yinghai Lu 7d97277b75 acpi/x86: introduce __apci_map_table, v4
to prevent wrongly overwriting fixmap that still want to use.

ACPI used to rely on low mappings being all linearly mapped and
grew a habit: it never really unmapped certain kinds of tables
after use.

This can cause problems - for example the hypothetical case
when some spurious access still references it.

v2: remove prev_map and prev_size in __apci_map_table
v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to
early_acpi_os_unmap_memory
v4: fix typo in one acpi_get_table_with_size calling

Zhang Rui 19cd847ab2 ACPI: fix hotplug race
The hotplug notification handler and drivers' notification handler all
run in one workqueue.  Before hotplug removes an acpi device, the
device driver's notification handler is already be recorded to run just
after global notification handler.  After hotplug notification handler
runs, acpica will notice a NULL notification handler and crash.

So now we run run hotplug in another workqueue and wait
for all acpi notication handlers finish.
This was found in battery hotplug, but actually all
hotplug can be affected.

ACPI currently emulates a timeout for semaphores with calls to
down_trylock and sleep.  This produces horrible behaviour in terms of
fairness and excessive wakeups.  Now that we have a unified semaphore

Linus Torvalds 9a9e0d6855 ACPI: Remove ACPI_CUSTOM_DSDT_INITRD option
This essentially reverts commit 71fc47a9ad
("ACPI: basic initramfs DSDT override support"), because the code simply
isn't ready.

It did ugly things to the init sequence to populate the rootfs image
early, but that just ended up showing other problems with the whole
approach.  The fact is, the VFS layer simply isn't initialized this
early, and the relevant ACPI code should either run much later, or this
shouldn't be done at all.

For 2.6.25, we'll just pick the latter option.  We can revisit this
concept later if necessary.

Linus Torvalds 10270d4838 acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()
The raw_pci_read() interface (as the raw_pci_ops->read() before it)
unconditionally fills in a 32-bit integer return value regardless of the
size of the operation requested.

So claiming to take a "void *" is wrong, as is passing in a pointer to
just a byte variable.

Thomas Renninger df92e69599 ACPI: track opregion names to avoid driver resource conflicts.
Small ACPICA extension to be able to store the name of operation regions in osl.c later

In ACPI, AML can define accesses to IO ports and System Memory by Operation
Regions.  Those are not registered as done by PNPACPI using resource templates
(and _CRS/_SRS methods).

The IO ports and System Memory regions may get accessed by arbitrary AML code.
 When native drivers are accessing the same resources bad things can happen
(e.g.  a critical shutdown temperature of 3000 C every 2 months or so).

It is not really possible to register the operation regions via
request_resource, as they often overlap with pnp or other resources (e.g.
statically setup IO resources below 0x100).

This approach stores all Operation Region declarations (IO and System Memory
only) at ACPI table parse time.  It offers a similar functionality like
request_region and let drivers which are known to possibly use the same IO
ports and Memory which are also often used by ACPI (hwmon and i2c) check for
ACPI interference.

A boot parameter acpi_enforce_resources=strict/lax/no is provided, which
is default set to lax:
  - strict: let conflicting drivers fail to load with an error message
  - lax:    let conflicting driver work normal with a warning message
  - no:     no functional change at all
Depending on the feedback and the kind of interferences we see, this
should be set to strict at later time.

Goal of this patch set is:
  - Identify ACPI interferences in bug reports (very hard to reproduce
    and to identify)
  - Find BIOSes for that an ACPI driver should exist for specific HW
    instead of a native one.
  - stability in general

Provide acpi_check_{mem_}region.

Drivers can additionally check against possible ACPI interference by also
invoking this shortly before they call request_region.
If -EBUSY is returned, the driver must not load.
Use acpi_enforce_resources=strict/lax/no options to:
  - strict: let conflicting drivers fail to load with an error message
  - lax:    let conflicting driver work normal with a warning message
  - no:     no functional change at all

ACPI tables follow a tree structure in memory.
The root of the tree is the RSDP (Root System Description Pointer).

To find the RSDP, the OS searches for the signature "RSD PTR "
in well known physical memory locations.  Then the OS computes
a table checksum to verify that the signature is really part
of a valid table header.

Some systems have a proper signature but an invalid checksum;
followed elsewhere by a proper signature with valid checksum.

The Linux RSDP scanning code bailed out on those systems
and as a result they booted with ACPI disabled.

Fix this by deleting the Linux RSDP scanning code and
plugging in the ACPICA RSDP scanning code.
