2007-11-20ACPI: EC: Workaround for optimized controllers (version 3)Alexey Starikovskiy
Some controllers fail to send confirmation GPE after address or data write. Detect this and don't expect such confirmation in future. This is a generalization of previous workaround (66c5f4e7367b0085652931b2f3366de29e7ff5ec), which did only read address.

2007-11-19cpuidle: fix HP nx6125 regressionVenkatesh Pallipadi
Fix for http://bugzilla.kernel.org/show_bug.cgi?id=9355 cpuidle always used to fallback to C2 if there is some bm activity while entering C3. But, presence of C2 is not always guaranteed. Change cpuidle algorithm to detect a safe_state to fallback in case of bm_activity and use that state instead of C2.

2007-11-19ACPI: thinkpad-acpi: fix oops when a module parameter has no valueHenrique de Moraes Holschuh
set_ibm_param() could OOPS with a NULL pointer derreference if one did not give any values for a module parameter it handles. This would, of course, cause all sort of trouble for future modprobing and require a reboot to clean up properly. Fix it by returning -EINVAL if no values are given for the parameter, and also avoid any nastyness from BUG_ON while at it.

2007-11-16ACPI: Get throttling info from BIOS only after evaluating _PDCZhao Yakui
Previously _PDC was evaluated later, and thus we'd not get the chance to tell the BIOS that we can suport FixedHW registers (MSRs) and the BIOS would always ask us to use System I/O access for throttling.

2007-11-16ACPI: Use _TSS for throttling control, when present. Add error checks.Zhao Yakui
_TSS was erroneously ignored, in favor of the FADT. When TSS is used, the access width is included in the PTC control/status register. So it is unnecessary that the access bit width is multiplied by 8. At the same time the bit_offset should be considered for system I/O Access. It should be checked the bit_width and bit_offset of PTC regsiter in order to avoid the failure of system I/O access. It means that bit_width plus bit_offset can't be greater than 32.

2007-11-16ACPI: Enforce T-state limit changes immediatelyZhao Yakui
When a T-state limit change notification is received, Linux must evaluate _TPC and change its current T-state immediately to comply with the new limit.
