Merge tag 'x86_misc_for_7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc x86 updates from Dave Hansen:
"The usual smattering of x86/misc changes.
The IPv6 patch in here surprised me in a couple of ways. First, the
function it inlines is able to eat a lot more CPU time than I would
have expected. Second, the inlining does not seem to bloat the kernel,
at least in the configs folks have tested.
- Inline x86-specific IPv6 checksum helper
- Update IOMMU docs to use stable identifiers
- Print unhashed pointers on fatal stack overflows"
