x86 ACPI: normalize segment descriptor register on resume

2008-07-05T06:25:40Z

Some Dell laptops enter resume with apparent garbage in the segment descriptor registers (almost certainly the result of a botched transition from protected to real mode.) The only way to clean that up is to enter protected mode ourselves and clean out the descriptor registers. This fixes resume on Dell XPS M1210 and Dell D620.

rtc: fix CMOS time error after writing /proc/acpi/alarm

2008-07-04T17:40:05Z

When writing /proc/acpi/alarm in adjust mode, e.g. echo "+0000-00-00 00:00:15" >/proc/acpi/alarm The "century" field should be read and added to "year" field before writing, otherwise the CMOS time will go back to 2000 years ago, e.g. # cat /proc/acpi/alarm 0008-06-21 11:38:46 Then the system time may be reset to the date of manufacture after rebooting. This patch fixed this issue.

The child of a video bus device is not alway a video device. It should be a warn message rather than an exception here. http://bugzilla.kernel.org/show_bug.cgi?id=9761 Signed-off-by: Zhang Rui Signed-off-by: Len Brown

ACPI: Reject below-freezing temperatures as invalid critical temperatures

2008-06-11T23:13:47Z

My laptop thinks that it's a good idea to give -73C as the critical CPU temperature.... which isn't the best thing since it causes a shutdown right at bootup. Temperatures below freezing are clearly invalid critical thresholds so just reject these as such. Signed-off-by: Arjan van de Ven Acked-by: Zhang Rui Signed-off-by: Len Brown
