ACPICA: executer/exsystem: Inform users about ACPI spec violation
ACPICA commit 05ba545ce7859392250b18c10081db25c90ed8d7
Values greater than 100 microseconds violate the ACPI specification, so
warn users about it.
From ACPI Specification version 6.2 Errata A, 19.6.128 *Stall (Stall for
a Short Time)*:
> The implementation of Stall is OS-specific, but must not relinquish
> control of the processor. Because of this, delays longer than 100
> microseconds must use Sleep instead of Stall.
