Move "tdp_mmu_page" into the 1-byte void left by the recently removed "mmio_cached" so that it resides in the first 64 bytes of kvm_mmu_page, i.e. in the same cache line as the most commonly accessed fields. Don't bother wrapping tdp_mmu_page in CONFIG_X86_64, including the field in 32-bit builds doesn't affect the size of kvm_mmu_page, and a future patch can always wrap the field in the unlikely event KVM gains a 1-byte flag that is 32-bit specific. Note, the size of kvm_mmu_page is also unchanged on CONFIG_X86_64=y due to it previously sharing an 8-byte chunk with write_flooding_count. No functional change intended.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
