ACPI and power management fixes for 3.14-rc7
- A recent ACPI resources handling fix overlooked the fact that it had to update the ACPI PNP subsystem's resources parsing too and caused confusing warning messages to be printed during system intialization on some systems (with arguably buggy ACPI tables). Fix from Zhang Rui. - Moving the early ACPI initialization before timekeeping_init() earlier in this cycle broke fast TSC calibration on at least one system, so it needs to be done later, but still before efi_enter_virtual_mode() to allow the EFI initialization to refer to ACPI. - A change related to code duplication reduction in the cpufreq core inadvertently caused cpufreq intialization to fail for some CPUs handled by intel_pstate by adding checks that may fail for that driver, but aren't even necessary when it is used. The issue is addressed by preventing those checks from run in the configurations in which they aren't needed. - If the Hardware Reduced ACPI flag is set in the ACPI tables, system suspend, hibernation and ACPI power off will only work when special sleep control and sleep status registeres are provided (their addresses in the ACPI tables are not zero). If those registers are not available, the features in question have no chances to work, so they shouldn't even be regarded as supported. That helps with power off in particular, because alternative power off methods may be used then and they may actually work. / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJTIyh1AAoJEILEb/54YlRxvw0P/RZIXtY5+c87JSRy+T1BBhN0 icpA7Qxu2unfckyR+anEIwrOFV7cvAMti7vJONWtSaFjp4sF8u2oEzs5T92DN74z 455sdieSZiTwDlvcbehSiaX6LFniK5OYLZ2RFGYh1D9uoxCSzfb9eugo7RNR+2iO UMTMQG2RmI2bmjLHLTzotMRxmjRd8RSMVAwvyNULgDAZlrmfKwojqKyJUB7NThAm kfAqVfzGs49+i0KF9hQrMeCEfNQF3Kj/HWMM78GHBNYu1uJVv+gXxMRUd8F9rGAO d4Xy14lfLpjPeH/DCO+hqA9eu74gM5nwjM3DbUnsFtt+FUmyBPemnTHCksUfHEeH wZlzuW0CndRqLijQa9tcFD6eeyh2tMztXCDu8r/UhpW1yGPkmW+SAU36SqqbmaGv knU+2jte4i/p4etNyPlfNb9mX9G59QQLISkRRfD8hnMm79TGaVT1tVGQ8RCqEG8p 73kVhISZ2WLjO9dLG5q/3uzFvZdJNWPfI/9l570mz2M5+X7VeCMA/tDx5ofDz/hQ 5JWvqIzYDSSOGxTtB1xR9TuwtQblAnsiVlqUoEwfqZ8O8u+RdvP5ymgUREPvLQFN jkCS1hdFleudZxqrn29MeEOJJg7DvFPyliMVvCxB2k1bg4HgJYWoZ0Hv0v0SKTd9 aCjbIOYxiLYV9clBSyLZ =d2+L -----END PGP SIGNATURE-----
