ACPI: ec: fix race in status register access

Delay the read of the EC status register until
after the event that caused it occurs -- otherwise
it is possible to read and act on stale status that was
associated with the previous event.

Do this with a perpetually incrementing "event_count" to detect
when a new event occurs and it is safe to read status.

There is no workaround for polling mode -- it is inherently
exposed to reading and acting on stale status, since it
doesn't have an interrupt to tell it the event completed.

ACPI: make blacklist more verbose

IMHO, ACPI disabled due to DMI failure or blacklisted year should be noted,
as is done with other ACPI blacklisting.

This will help people troubleshoot when ACPI isn't working. Status quo is
a mysterious "ACPI Disabled" message without explanation on BIOS that
implements ACPI but not DMI. This is actually fairly common on embedded
x86 boards.

libata-acpi: allow _GTF on SATA, but disable on PATA for now

The ACPI specification states, and BIOS implementations depend on,
_STM being called before _GTF.

SATA does this, but PATA does not. So for now, simply
prevent execution of _GTF on PATA devices. Longer term we
should implement ACPI support for PATA devices in libata.

ACPI: repair nvidia early quirk breakage on x86_64

x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET.
However, the quirk works by checking for not finding the HPET...

Delete the nvidia_hpet_detected flag and simply test for
not finding the HPET, which is simple to do now that
acpi_table_parse returns 1 on failure.

This would apply to re-enabling a device any-time after boot,
not just after resume from S3.

ACPI: fix boot hang w/o "noapic" on MSI MS-6390-L

This is a workaround to handle a BIOS bug where the
programmer exchanged the name and index fields of
a _PRT entry. Apparently this BIOS error does not
confuse Windows and thus it lurks in the field
on various machines.

ACPI: Altix: reinitialize acpi tables

To provide compatibilty with SN kernels that do and do not
have ACPI IO support, the SN PROM must build different
versions of some ACPI tables based on which kernel is booting.
As such, the tables may have to change at kernel boot time.
By default, prior to kernel boot, the PROM builds an empty
DSDT (header only) and no SSDTs. If an ACPI capable kernel
boots, the kernel will notify the PROM, at platform setup time,
and the PROM will build full DSDT and SSDT tables.

With the latest changes to acpi_table_init(), the table lengths
are saved, and when our PROM changes them, the changes are not seen,
and the kernel will crash on boot. Because of issues with kexec support,
we are not able to create the tables prior to acpi_table_init().
As a result, we are making a second call to acpi_table_init() to
process the rebuilt DSDT and SSDTs.

ACPI: Altix: cannot register acpi bus driver before bus scan

SN code to initialize the Hub/TIO infrastructure needs to
execute before bus scanning. This was previously done with
an early call to acpi_bus_register_driver(). But now that
ACPI is using the Linux driver model, a driver cannot be registered
that early. Make changes to have the init routines invoked via
calls to acpi_get_devices().
