From 9892dd23cbbfab1f7d4818622296e415979a9c77 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Wed, 18 Feb 2009 15:10:07 +0800 Subject: ACPICA: Optimize ACPI register locking Removed locking for reads from the ACPI bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is not required when reading the single-bit registers. The acpi_get_register_unlocked function is no longer needed and has been removed. This will improve performance for reads on these registers.
