Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial
Pull fixup for trivial branch from Jiri Kosina:
"Unfortunately I made a mistake when merging into for-linus branch, and
omitted one pre-requisity patch for a few other patches (which have
been Acked by the appropriate maintainers) in the series. Mea culpa
maxima, sorry for that."
The trivial branch added %pSR usage before actually teaching vsnprintf()
about the 'R' part of %pSR. The 'R' causes the symbol translation to do
a "__builtin_extract_return_addr()" before symbol lookup.
That said, on most architectures __builtin_extract_return_addr() isn't
likely to do anything special, so it probably is not normally
noticeable.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial:
vsprintf: Add extension %pSR - print_symbol replacement
