This patch is for some machines which report the battery current
as a 16-bit signed negative when it is charging. This is caused
by DSDT bug. The commit bc76f90b8a5cf4aceedf210d08d5e8292f820cec
has resolved the problem for Acer laptops. But some other machines
also have such problem.
https://bugzilla.kernel.org/show_bug.cgi?id=33722
Since it is improper that the current is above 32A on laptops
whether on AC or on battery, this patch is to check the current and
take its absolute value as current and producing a message when it
is negative in s16.
Remove Acer quirk, as this workaround handles Acer too.

We can only sort the _TSS return package if there is no _PSS
in the same scope. This is because if _PSS is present, the ACPI
specification dictates that the _TSS Power Dissipation field is
to be ignored, and therefore some BIOSs leave garbage values in
the _TSS Power field(s). In this case, it is best to just return
the _TSS package as-is.

APEI firmware first mode must be turned on explicitly on some

In APEI firmware first mode, hardware error is reported by hardware to
firmware firstly, then firmware reports the error to Linux in a GHES
error record via POLL/SCI/IRQ/NMI etc.
This may result in some issues if OS has no full APEI support. So
some firmware implementation will work in a back-compatible mode by
default. Where firmware will only notify OS in old-fashion, without
GHES record. For example, for a fatal hardware error, only NMI is
signaled, no GHES record.
To gain full APEI power on these machines, APEI bit in generic _OSC
call can be specified to tell firmware that Linux has full APEI
support. This patch adds the APEI bit support in generic _OSC call.

GHES (Generic Hardware Error Source) is used to process hardware error

can be turned on but can not be turned off, it is unreasonable to
unload the GHES module with firmware first mode turned on. To avoid
confusion, this patch makes GHES can be enabled/disabled in
configuration time, but not built as module and unloaded at run time.

Some actions in APEI ERST and EINJ tables are optional, for example,
ACPI_EINJ_BEGIN_OPERATION action is used to do some preparation for
error injection, and firmware may choose to do nothing here. While
some other actions are mandatory, for example, firmware must provide
ACPI_EINJ_GET_ERROR_TYPE implementation.
Original implementation treats all actions as optional (that is, can
have no instructions), that may cause issue if firmware does not
provide some mandatory actions. To fix this, this patch adds
apei_exec_run_optional, which should be used for optional actions.
The original apei_exec_run should be used for mandatory actions.

printk is used by GHES to report hardware errors. Normally, the
printk will be ratelimited to avoid too many hardware error reports in
kernel log. Because there may be thousands or even millions of
corrected hardware errors during system running.
That is different for fatal hardware error, because system will go
panic as soon as possible, there will be no more than several error
records. And these error records are valuable for system fault
diagnosis, so they should not be ratelimited.

All ACPICA locks are allocated by the same function,
acpi_os_create_lock(), with the help of a local variable called
"lock". Thus, when lockdep is enabled, it uses "lock" as the
name of all those locks and regards them as instances of the same
lock, which causes it to report possible locking problems with them
when there aren't any.
To work around this problem, define acpi_os_create_lock() as a macro
and make it pass its argument to spin_lock_init(), so that lockdep
uses it as the name of the new lock. Define this macron in a
Linux-specific file, to minimize the resulting modifications of
the OS-independent ACPICA parts.
This change is based on an earlier patch from Andrea Righi and it
addresses a regression from 2.6.39 tracked as

Processor (CPU1, 0x01, 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.

The presense of a writeq() implementation on 32-bit x86 that splits the
64-bit write into two 32-bit writes turns out to break the mpt2sas driver
(and in general is risky for drivers as was discussed in
<http://lkml.kernel.org/r/adaab6c1h7c.fsf@cisco.com>). To fix this,
revert 2c5643b1c5c7 ("x86: provide readq()/writeq() on 32-bit too") and
follow-on cleanups.
This unfortunately leads to pushing non-atomic definitions of readq() and
write() to various x86-only drivers that in the meantime started using the
definitions in the x86 version of <asm/io.h>. However as discussed
exhaustively, this is actually the right thing to do, because the right
way to split a 64-bit transaction is hardware dependent and therefore
belongs in the hardware driver (eg mpt2sas needs a spinlock to make sure
no other accesses occur in between the two halves of the access).
Build tested on 32- and 64-bit x86 allmodconfig.
