Merge branch 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull x86 IOSF platform updates from Ingo Molnar:
"IOSF (Intel OnChip System Fabric) updates:
- generalize the IOSF interface to allow mixed mode drivers: non-IOSF
drivers to utilize of IOSF features on IOSF platforms.
- add 'Quark X1000' IOSF/MBI support
- clean up BayTrail and Quark PCI ID enumeration"
* 'x86-platform-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, iosf: Add PCI ID macros for better readability
x86, iosf: Add Quark X1000 PCI ID
x86, iosf: Added Quark MBI identifiers
x86, iosf: Make IOSF driver modular and usable by more drivers
