Merge branch 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull kdump fixes from Peter Anvin:
"The kexec/kdump people have found several problems with the support
for loading over 4 GiB that was introduced in this merge cycle. This
is partly due to a number of design problems inherent in the way the
various pieces of kdump fit together (it is pretty horrifically manual
in many places.)
After a *lot* of iterations this is the patchset that was agreed upon,
but of course it is now very late in the cycle. However, because it
changes both the syntax and semantics of the crashkernel option, it
would be desirable to avoid a stable release with the broken
interfaces."
I'm not happy with the timing, since originally the plan was to release
the final 3.9 tomorrow. But apparently I'm doing an -rc8 instead...
* 'x86-kdump-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
kexec: use Crash kernel for Crash kernel low
