ACPICA commit a78506e0ce8ab1d20db2a055d99cf9143e89eb29 LoadTable allows an alternative RootPathString than the default "\", while the new table execution support fails to keep this logic. This regression can be detected by ASLTS - TLT0.tst4, this patch fixes this regression. Linux upstream is not affected by this regression as we haven't enabled the new table execution support there.
