From df6fd31995cb2e38b2a7e94bc8f1559b8f55404e Mon Sep 17 00:00:00 2001 From: "Starikovskiy, Alexey Y" Date: Fri, 18 Aug 2006 11:23:00 -0400 Subject: ACPI: relax BAD_MADT_ENTRY check to allow LSAPIC variable length string UIDs ACPI 3.0 appended a variable length UID string to the LAPIC structure as part of support for > 256 processors. So the BAD_MADT_ENTRY() sanity check can no longer compare for equality with a fixed structure length.
