Pull x86 fixes from Ingo Molnar:
"Misc fixes:
- A rather involved set of memory hardware encryption fixes to
support the early loading of microcode files via the initrd. These
are larger than what we normally take at such a late -rc stage, but
there are two mitigating factors: 1) much of the changes are
limited to the SME code itself 2) being able to early load
microcode has increased importance in the post-Meltdown/Spectre
era.
- An IRQ vector allocator fix
- An Intel RDT driver use-after-free fix
- An APIC driver bug fix/revert to make certain older systems boot
again
- A pkeys ABI fix
- TSC calibration fixes
- A kdump fix"

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
