x86, 8042: Enable A20 using KBC to fix S3 resume on some MSI laptops 2013-01-03T03:33:36+00:00 Ondrej Zary linux@rainbow-software.org 2012-12-11T21:18:05+00:00 6f2aad2b4120b1770d8bc89c5b6feef347238585 commit ad68652412276f68ad4fe3e1ecf5ee6880876783 upstream. Some MSI laptop BIOSes are broken - INT 15h code uses port 92h to enable A20 line but resume code assumes that KBC was used.
