Merge branch 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 boot updates from Ingo Molnar:
"The main changes were:
- Extend the boot protocol to allow future extensions without hitting
the setup_header size limit.
- Add quirk to devicetree systems to disable the RTC unless it's
listed as a supported device.
- Fix ld.lld linker pedantry"
* 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/boot: Introduce setup_indirect
x86/boot: Introduce kernel_info.setup_type_max
x86/boot: Introduce kernel_info
x86/init: Allow DT configured systems to disable RTC at boot time
x86/realmode: Explicitly set entry point via ENTRY in linker script
