Hi Matt,
I think this change could result in problems such as the page-aligned text sections (recently renamed from .text.page_aligned to .text..page_aligned) that exist in some architectures being included the main text section in a non-page-aligned fashion (and similar issues for other .text.foo sections).
I was planning to submit in the next couple weeks a change that adds support for building the kernel with -ffunction-sections -fdata-sections, which would have as a piece of it adding to TEXT_TEXT the following expression:
*(.text.[A-Za-z$_]*) /* handle -ffunction-sections */\
which should match the .text.foo sections generated by -ffunction-sections but not the kernel's special sections which now all have names of the form .text..foo. I suspect after that change, the cleanup of deleting .text.* from the various architecture linker scripts that reference it should be possible.
