ACPI: Add D3 cold state
_SxW returns an Integer containing the lowest D-state supported in state
Sx. If OSPM has not indicated that it supports _PR3, then the value “3”
corresponds to D3. If it has indicated _PR3 support, the value “3”
represents D3hot and the value “4” represents D3cold.
Linux does set _OSC._PR3, so we should fix it to expect that _SxW can
return 4.

ACPI: processor: fix processor_physically_present in UP kernel
Usually, there are multiple processors defined in ACPI table, for
example
Scope (_PR)
{
Processor (CPU0, 0x00, 0x00000410, 0x06) {}
Processor (CPU1, 0x01, 0x00000410, 0x06) {}
Processor (CPU2, 0x02, 0x00000410, 0x06) {}
Processor (CPU3, 0x03, 0x00000410, 0x06) {}
}
processor_physically_present(...) will be called to check whether those
processors are physically present.
Currently we have below codes in processor_physically_present,
cpuid = acpi_get_cpuid(...);
if ((cpuid == -1) && (num_possible_cpus() > 1))
return false;
return true;
In UP kernel, acpi_get_cpuid(...) always return -1 and
num_possible_cpus() always return 1, so
processor_physically_present(...) always returns true for all passed in
processor handles.
This is wrong for UP processor or SMP processor running UP kernel.
This patch removes the !SMP version of acpi_get_cpuid(), so both UP and
SMP kernel use the same acpi_get_cpuid function.
And for UP kernel, only processor 0 is valid.

ACPI: Split out custom_method functionality into an own driver
With /sys/kernel/debug/acpi/custom_method root can write
to arbitrary memory and increase his priveleges, even if
these are restricted.
-> Make this an own debug .config option and warn about the
security issue in the config description.
-> Still keep acpi/debugfs.c which now only creates an empty
/sys/kernel/debug/acpi directory. There might be other
users of it later.

ACPICA: Execute an orphan _REG method under the EC device
This change will force the execution of a _REG method underneath

of type EmbeddedControl. Fixes a problem seen on some machines
and apparently is compatible with Windows behavior.

This change adds another group of predefined names to the list

removed. This group is the names that return a single

as integers, buffers, strings. This includes: _ALx,_BCL,_CID,
_DOD,_EDL,_FIX,_PCL,_PLD,_PMD,_PRx,_PSL,_Sx, and _TZD.

ACPI: EC: add another DMI check for ASUS hardware
Commit 0adf3c746a73684b3f8c2821a584e1db998f61e9 introduced a regression
by making the ECDT validation test for ASUS hardware more restrictive.
The previous test used the dmi_name_in_vendors function which searches
a number of DMI fields, while the new test checked only the BIOS
vendor, which is known to not match on an ASUS F5GL laptop which
requires ECDT validation.
Add a rule to ec_dmi_table based on an alternative DMI pattern for
ASUS hardware as found elsewhere in the kernel.

ACPICA: Fix code divergence of global lock handling
Commit 9cd0314(ACPI / ACPICA: Fix global lock acquisition) was backported
into ACPICA code base, and some divergence was introduced.
This patch fixed it,
- rename acpi_ev_global_lock_pending/acpi_ev_global_lock_pending_lock
to acpi_gbl_global_lock_pending/acpi_gbl_global_lock_pending_lock.
- move the initialization of acpi_gbl_global_lock_pending_lock from
acpi_ut_mutex_initialize to acpi_ev_init_global_lock_handler.
