Daniel Verkamp 00571bf162 acpi_tables: avoid extra AML allocations and copies ... Many of the Aml implementations wrote temporary results into a Vec<u8>, then appended that Vec to the aml bytestream. Instead, append or insert directly into the aml vector to avoid the extra allocations and copies. This also eliminates the confusing reverse() calls when inserting the PkgLength, which were needed due to inserting the encoded length one byte at a time at the beginning of the bytestream; instead, use the splice() function to insert all of the bytes in order at once.
