ACPI suspend: Always use the 32-bit waking vector
According to the ACPI specification 2.0c and later, the 64-bit waking vector should be cleared and the 32-bit waking vector should be used, unless we want the wake-up code to be called by the BIOS in Protected Mode. Moreover, some systems (for example HP dv5-1004nr) are known to fail to resume if the 64-bit waking vector is used. Therefore, modify the code to clear the 64-bit waking vector, for FACS version 1 or greater, and set the 32-bit one before suspend. http://bugzilla.kernel.org/show_bug.cgi?id=11368 Signed-off-by: Rafael J.
