ACPI / AC: change notification handler type to ACPI_ALL_NOTIFY

With kernel 3.13rc5 there are no AC adapter notifications on my laptop.

Commit cc8ef5270734 "ACPI / AC: convert ACPI ac driver to platform bus"
changed the driver to listen to device notifications only. However, AML
code on my laptop notifies the driver with zero event.

This patch changes the driver to listen to all events again.

ACPI / TPM: fix memory leak when walking ACPI namespace

In function ppi_callback(), memory allocated by acpi_get_name() will get
leaked when current device isn't the desired TPM device, so fix the
memory leak.

intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.

KVM environments do not support APERF/MPERF MSRs. intel_pstate cannot
operate without these registers.

The previous validity checks in intel_pstate_msrs_not_valid() are
insufficent in nested KVMs.

ACPI / Battery: Add a _BIX quirk for NEC LZ750/LS

The AML method _BIX of NEC LZ750/LS returns a broken package which
skips the first member "Revision" (ACPI 5.0, Table 10-234).

Add a quirk for this machine to skip member "Revision" during parsing
the package returned by _BIX.

Revert "intel_idle: mark states tables with __initdata tag"

This reverts commit 9d046ccb98085f1d437585f84748c783a04ba240.

Commit 9d046ccb98085 marks all state tables with __initdata, but
the state table may be accessed when doing CPU online, which then
causing system crash as below:
