SubjectRe: [PATCH 1/5] vmlinux.lds.h: Include *(.text.*) in TEXT_TEXT

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.
