Merge branch 'linux_next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/i7core
* 'linux_next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/i7core: (83 commits) i7core_edac: Better describe the supported devices Add support for Westmere to i7core_edac driver i7core_edac: don't free on success i7core_edac: Add support for X5670 Always call i7core_[ur]dimm_check_mc_ecc_err i7core_edac: fix memory leak of i7core_dev EDAC: add __init to i7core_xeon_pci_fixup i7core_edac: Fix wrong device id for channel 1 devices i7core: add support for Lynnfield alternate address i7core_edac: Add initial support for Lynnfield i7core_edac: do not export static functions edac: fix i7core build edac: i7core_edac produces undefined behaviour on 32bit i7core_edac: Use a more generic approach for probing PCI devices i7core_edac: PCI device is called NONCORE, instead of NOCORE i7core_edac: Fix ringbuffer maxsize i7core_edac: First store, then increment i7core_edac: Better parse "any" addrmask i7core_edac: Use a lockless ringbuffer edac: Create an unique instance for each kobj ...
