Revision c4e1acbb35e4a3838cdfc0e7f8237e844aff00b6 authored by Rafael J. Wysocki on 12 March 2014, 23:22:58 UTC, committed by Rafael J. Wysocki on 12 March 2014, 23:53:51 UTC
Commit 73f7d1ca3263 (ACPI / init: Run acpi_early_init() before timekeeping_init()) optimistically moved the early ACPI initialization before timekeeping_init(), but that didn't work, because it broke fast TSC calibration for Julian Wollrath on Thinkpad x121e (and most likely for others too). The reason is that acpi_early_init() enables the SCI and that interferes with the fast TSC calibration mechanism. Thus follow the original idea to execute acpi_early_init() before efi_enter_virtual_mode() to help the EFI people for now and we can revisit the other problem that commit 73f7d1ca3263 attempted to address in the future (if really necessary).
