ACPICA: Fix possible buffer overflow during a field unit read operation

2013-05-19T17:04:36+00:00

commit 61388f9e5d93053cf399a356414f31f9b4814c6d upstream.

Can only happen under these conditions: 1) The DSDT version is 1,
meaning integers are 32-bits.  2) The field is between 33 and 64
bits long.

It applies cleanly back to ACPICA 20100806+ (Linux v2.6.37+).

ACPICA: Fix to allow region arguments to reference other scopes

2012-04-22T23:21:43+00:00

commit 8931d9ea78848b073bf299594f148b83abde4a5e upstream.

ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359)
ACPI Exception: AE_NOT_FOUND, Could not execute arguments for [RAMW] (Region) (20110112/nsinit-349)

    Scope (_SB)
    {
        Name (RAMB, 0xDF5A1018)
        OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000)
    }

For above ASL code, we need to save scope node(\_SB) to lookup
the argument node(\_SB.RAMB).

ACPICA: Fix regression in FADT revision checks

2012-04-13T15:14:06+00:00

commit 3e80acd1af40fcd91a200b0416a7616b20c5d647 upstream.

	commit 64b3db22c04586997ab4be46dd5a5b99f8a2d390 (2.6.39),
"Remove use of unreliable FADT revision field" causes regression
for old P4 systems because now cst_control and other fields are
not reset to 0.

	The effect is that acpi_processor_power_init will notice
cst_control != 0 and a write to CST_CNT register is performed
that should not happen. As result, the system oopses after the
"No _CST, giving up" message, sometimes in acpi_ns_internalize_name,
sometimes in acpi_ns_get_type, usually at random places. May be
during migration to CPU 1 in acpi_processor_get_throttling.

	Every one of these settings help to avoid this problem:
 - acpi=off
 - processor.nocst=1
 - maxcpus=1

	The fix is to update acpi_gbl_FADT.header.length after
the original value is used to check for old revisions.

ACPICA: Put back the call to acpi_os_validate_address

2012-01-26T01:24:58+00:00

commit da4d8b287abe783d30e968155614531a0937d090 upstream.

The call to acpi_os_validate_address in acpi_ds_get_region_arguments was
removed by mistake in commit 9ad19ac(ACPICA: Split large dsopcode and
dsload.c files).

Put it back.

acpica: ACPI_MAX_SLEEP should be 2 sec, not 20

2011-10-03T18:40:25+00:00

commit b33c25d6a62ac253caabda2b5f43258abff451c0 upstream.

This limit is a workaround for AML that sleeps too long,
but the workaround didn't work b/c of a typo.

ACPICA: Do not repair _TSS return package if _PSS is present

2011-10-03T18:40:21+00:00

commit 8f9c91273e36e5762c617c23e4fd48d5172e0dac upstream.

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.
