ACPICA: Debug output: Do not emit function nesting level for kernel build.

The nesting level is really only useful during a single-thread
execution. Therefore, only enable this output for the AcpiExec
utility. Also, only emit the thread ID when executing under AcpiExec.
(Context switches are still detected and a message is emitted.)
ACPICA BZ 972.

ACPICA: Tests: Add CHECKSUM_ABORT protection for test utilities.

This patch adds protection around ACPI_CHECKSUM_ABORT so that ACPI
user space test utilities can re-define it for their own purposes
(currently used by ASLTS build environment).

This patch doesn't affect Linux kernel behavior.  Lv Zheng.

ACPICA: Resources: Fix loop termination for the get AML length function.

The loop terminates on a NULL resource pointer, which can never
happen since the loop simply increments a valid resource pointer.
This fix changes the loop to terminate on an end-of-buffer condition.

Problem can be seen by callers to AcpiSetCurrentResources with an
invalid or corrupted resource descriptor; or a resource descriptor
without an END_TAG descriptor.

ACPICA: Delete all attached data objects during namespace node deletion.

This fix updates namespace node deletion to delete the entire list
of attached objects (attached via acpi_attach_data) instead of
just one of the attached items. ACPICA BZ 1024.

ACPICA: Add support to delete all objects attached to the root namespace node.

This fix deletes any and all objects that have been attached to the
root node (via acpi_attach_data). Reported by Tomasz Nowicki.

ACPI / sysfs: Fix incorrect ACPI tables walk in acpi_tables_sysfs_init()

Message-ID: <87d2lu83a0.fsf@tldlab276.tl.intel.com>
MIME-Version: 1.0
Content-Type: text/plain
--text follows this line--

When executing on an ACPI Hardware Reduced hardware, all the ACPI
tables are not exposed in sysfs due to the fact that FACS is
silently ignored by the kernel in the ACPI hardware reduced mode
and, moreover, the acpi_tables_sysfs_init() ACPI table walk
is buggy and stops too soon.

The acpi_tables_sysfs_init() function should rely on the acpi_status
return value from acpi_get_table_by_index() to decide whether or not
to stop the iteration (the walk should only be terminated when that
value is AE_BAD_PARAMETER).  This way, when running in an ACPI Harware
Reduced environment (where the FACS table is silently ignored by the
kernel) or if some ACPI tables are not correctly memory mapped or
have bad checksums, it will still walk through the remaining tables
that may be correct.
