Subject: ACPICA: Remove obsolete acpi_os_validate_address interface
X-Git-Tag: v2.6.30-rc1~199^2~36
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=f9ca058430333c9a24c5ca926aa445125f88df18;p=~shefty%2Frdma-dev.git

ACPICA: Remove obsolete acpi_os_validate_address interface

This interface is no longer necessary. Requests should be validated
on a per-field basis, not on the entire operation region.
