* x86: check for and defend against BIOS memory corruptionJeremy Fitzhardinge2008-09-07
| | | | | | | | | | | | | | | Some BIOSes have been observed to corrupt memory in the low 64k. This change: - Reserves all memory which does not have to be in that area, to prevent it from being used as general memory by the kernel. Things like the SMP trampoline are still in the memory, however. - Clears the reserved memory so we can observe changes to it. - Adds a function check_for_bios_corruption() which checks and reports on memory becoming unexpectedly non-zero. Currently it's called in the x86 fault handler, and the powermanagement debug output. Signed-off-by: Jeremy Fitzhardinge <jeremy@goop.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | Apparently, there are more different versions of Lenovo 3000 N100, some of them working properly with active mux, and some of them requiring it being switched off. This patch applies 'nomux' only to the specific product name that is reported to behave badly unless 'nomux' is specified.

| * Input: bcm5974 - add BTN_TOUCH event for mousedev benefitHenrik Rydberg2008-09-04
| | | | | | | | | | | | | | | | | | The mousedev driver requires the use of BTN_TOUCH events to process ABS_X and ABS_Y events properly, which is what is needed for the bcm5974-based apple computers to have a functional pointer out-of-the-box.

| * Input: bcm5974 - improve finger tracking and countingHenrik Rydberg2008-09-04
| | | | | | | | | | | | | | | | | | | | | | | | | | The problem of finger tracking, i.e., when to switch focus from one finger to another on the trackpad, has been improved by utilizing more information from the bcm5974 chip output. This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced. Together with a pressure hysteresis window, this yields a more stable counting of the number of fingers on the trackpad.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current check for monotonicity is way too weak: Andreas Mohr reports ( http://lkml.org/lkml/2008/8/10/77 ) that on one of his test systems the current check only triggers in 50% of all cases, leading to catastrophic timer behaviour. To fix this issue, expand the check for monotonicity by doing ten consecutive tests instead of one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On all hardware (some Intel ICH4, PIIX4 and PIIX4E chipsets) affected by a hardware errata there's about a 4.2% chance that initialization of the ACPI PMTMR fails. On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable. Thanks to Andreas Mohr for spotting this issue.

The problem appears to be that if the adapter is put into D3_hot during ->shutdown(), it cannot be brought back into D0 after kexec (ref. http://marc.info/?l=linux-kernel&m=121900062814967&w=4). Therefore, only put forcedeth into D3 during ->shutdown() if the system is to be powered off. Signed-off-by: Rafael J.

This patch adds a check for the really black image case and stops dropping all frames as invalid in this case.
