Armin Wolf 21a08dab14 ACPICA: Abort AML bytecode execution when executing AML_FATAL_OP 
[ Upstream commit 026ad376a6 ]

The ACPI specification states that when executing AML_FATAL_OP,
the OS should log the fatal error event and shutdown in a timely
fashion.

Windows complies with this requirement by immediatly entering a
Bso_d, effectively aborting the execution of the AML bytecode in
question.

ACPICA however might continue with the AML bytecode execution
should acpi_os_signal() simply return AE_OK. This will cause issues
because ACPI BIOS implementations might assume that the Fatal()
operator does not return.

Fix this by aborting the AML bytecode execution in such a case
by returning AE_ERROR. Also turn struct acpi_signal_fatal_info into a
local variable because of its small size (12 bytes) and to ensure
that acpi_os_signal() always receives valid information about the
fatal ACPI BIOS error.
