There was a misplaced status test (two consequent tests without a
statement in between) in acpi_bus_init for ages. Remove it, since the
function which should be checked (acpi_os_initialize1) has BUG_ONs on
failure paths.

in a more clever way in the future.

Remove CONFIG_ACPI_SYSTEM. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".
Some things under CONFIG_ACPI_SYSTEM (acpi_irq_handled, acpi_os_gpe_count(),
event_is_open, register_acpi_notifier(), etc.) are used unconditionally
by the CA, the OSPM, and drivers, so we depend on them always being
present.

On hardware like the T61 it can take a couple of seconds for the battery
to start charging after the power is connected, and we incorrectly tell
userspace that we are fully charged, and then go back to charging.
Only mark a battery as fully charged when the preset charge matches either
the last full charge, or the design charge.

During early boot, ACPI RSDT/XSDT table entries are gathered into the
'initial_tables[]' array. This array is currently statically defined (see
./drivers/acpi/tables.c). When there are more table entries than can be
held in the 'initial_tables[]' array, the message "Truncating N table
entries!" is output. As currently implemented, this message will always
erroneously calculate N as 0.
This patch fixes the calculation that determines how many table entries
will be missing (truncated).
This modification may be used under either the GPL or the BSD-style
license used for Intel ACPI CA code.

Some devices trigger a DEVICE_CHECK on every evalutation of _STA. This
can also be seen in commit 8b59560a3b
(ACPI: dock: avoid check _STA method). If an undock is processed, the
dock driver sends a uevent and userspace might read the show_docked
property in sysfs. This causes an evaluation of _STA of the particular
device which causes the dock driver to immediately dock again.
In any case, evaluation of _STA (show_docked) does not necessarily mean
that we are docked, so check with the internal device structure.

When ACPI is disabled in the BIOS of this VIA C3 box,
it invalidates the RSDP, which Linux notices:
ACPI Error (tbxfroot-0218): A valid RSDP was not found [20080926]
Bug Linux neglected to disable ACPI at that stage,
and later scribbled on smp_found_config:
ACPI: No APIC-table, disabling MPS
But this box doesn't run well in legacy PIC mode,
it needed IOAPIC mode to perform correctly:
http://lkml.org/lkml/2009/2/5/39
So exit ACPI mode cleanly when we first detect
that it is hopeless.

CPU_IDLE=y has been default for ACPI=y since Nov-2007,
and has shipped in many distributions since then.
Here we delete the CPU_IDLE=n ACPI idle code, since
nobody should be using it, and we don't want to
maintain two versions.

According to the Spec the first two elements in the _BCL package won't be
regarded as the available brightness level. The first is the brightness when
full power is connected to the box(It means that the AC adapter is plugged).
The second is the brightness level when the box is on battery.
If the first two elements are still used while finding the next brightness
level, it will fall back to the lowest level when keeping on pressing
hotkey. (On some boxes the brightness will be changed twice when hotkey is
pressed once. One is in the ACPI video driver. The other is changed by sys I/F.
In the ACPI video driver the first two elements will be used while changing
the brightness. But the first two elements is skipped while using sys I/F.
In such case there exists the inconsistency).
So he first two elements had better be skipped while showing the available
brightness or finding the next brightness level.

It is true that BM_RLD needs to be set to enable
bus master activity to wake an older chipset (eg PIIX4) from C3.
This is contrary to the erroneous wording the ACPI 2.0, 3.0
specifications that suggests that BM_RLD is an indicator
rather than a control bit.
ACPI 1.0's correct wording should be restored in ACPI 4.0:
http://www.acpica.org/bugzilla/show_bug.cgi?id=689
But the kernel should not have to clear BM_RLD
when entering a non C3-type state just to set
it again when entering a C3-type C-state.
We should be able to set BM_RLD at boot time
and leave it alone -- removing the overhead of
accessing this IO register from the idle entry path.

PM1a_STS and PM1b_STS are twins that get OR'd together
on reads, and all writes are repeated to both.
The fields in PM1x_STS are single bits only,
there are no multi-bit fields.
So it is not necessary to lock PM1x_STS reads against
writes because it is impossible to read an intermediate
value of a single bit. It will either be 0 or 1,
even if a write is in progress during the read.
Reads are asynchronous to writes no matter if a lock
is used or not.

On some boxes there exist both RSDT and XSDT table. But unfortunately
sometimes there exists the following error when XSDT table is used:
a. 32/64X address mismatch
b. The 32/64X FACS address mismatch
In such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.
