turns certain relocation entries absolute. Section-relative symbols
that are part of otherwise empty sections are silently changed them to
absolute. We rely on section-relative symbols staying section-relative,
and actually have several sections in the linker script solely for this
purpose.
See for example
http://sourceware.org/bugzilla/show_bug.cgi?id=14052
We could just black-list the buggy linker, but it appears that it got
shipped in at least F17, and possibly other distros too, so it's sadly
not some rare unusual case.
This backports the workaround from the x86/trampoline branch, and as
Peter says: "This is not a minimal fix, not at all, but it is a tested
code base."

Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"A few small, but important fixes. Most of them are marked for stable
as well
- Fix failure to release a semaphore on error path in mtip32xx.
- Fix crashable condition in bio_get_nr_vecs().
- Don't mark end-of-disk buffers as mapped, limit it to i_size.
- Fix for build problem with CONFIG_BLOCK=n on arm at least.
- Fix for a buffer overlow on UUID partition printing.
- Trivial removal of unused variables in dac960."
