[ Upstream commit 3dfaea3811f8b6a89a347e8da9ab862cdf3e30fe ]
ACPICA commit 1a3a549286ea9db07d7ec700e7a70dd8bcc4354e
The macros to classify different AML exception codes are broken. For
instance,
ACPI_ENV_EXCEPTION(Status)
will always evaluate to zero due to
#define AE_CODE_ENVIRONMENTAL 0x0000
#define ACPI_ENV_EXCEPTION(Status) (Status & AE_CODE_ENVIRONMENTAL)
Similarly, ACPI_AML_EXCEPTION(Status) will evaluate to a non-zero
value for error codes of type AE_CODE_PROGRAMMER, AE_CODE_ACPI_TABLES,
as well as AE_CODE_AML, and not just AE_CODE_AML as the name suggests.
This commit fixes those checks.
Fixes: d46b6537f0ce ("ACPICA: AML Parser: ignore all exceptions resulting from
incorrect AML during table load")
