Subject: [PATCH 1/4] mips: use NOSAVE_DATA macro for .data.nosave section.

This has the consequence of replacing the alignment of _PAGE_SIZE with
an alignment of PAGE_SIZE.  I believe these have the same value.

.data.nosave should not need a separate output section; this change
moves it into the .data section.
