From 386e4a8358239f90275e1f93d5ad11cdc93c6453 Mon Sep 17 00:00:00 2001 From: Myron Stowe Date: Fri, 30 Jan 2009 15:44:53 -0700 Subject: [PATCH] ACPICA: Fix table entry truncation calculation During early boot, ACPI RSDT/XSDT table entries are gathered into the 'initial_tables[]' array. This array is currently statically defined (see ./drivers/acpi/tables.c). When there are more table entries than can be held in the 'initial_tables[]' array, the message "Truncating N table entries!" is output. As currently implemented, this message will always erroneously calculate N as 0. This patch fixes the calculation that determines how many table entries will be missing (truncated). This modification may be used under either the GPL or the BSD-style license used for Intel ACPI CA code.
