ACPICA: Disassembler: Abort on an invalid/unknown AML opcode
[ Upstream commit 6f0527b77d9e0129dd8e50945b0d610ed943d6b2 ]
ACPICA commit ed0389cb11a61e63c568ac1f67948fc6a7bd1aeb
An invalid opcode indicates something seriously wrong with the
input AML file. The AML parser is immediately confused and lost,
causing the resulting parse tree to be ill-formed. The actual
disassembly can then cause numerous unrelated errors and faults.
This change aborts the disassembly upon discovery of such an
opcode during the AML parse phase.
