Previously, the guest_fpu field was embedded in the kvm_vcpu_arch struct. Unfortunately, the field is quite large, (e.g., 4352 bytes on my current setup). This bloats the kvm_vcpu_arch struct for x86 into an order 3 memory allocation, which can become a problem on overcommitted machines. Thus, this patch moves the fpu state outside of the kvm_vcpu_arch struct. With this patch applied, the kvm_vcpu_arch struct is reduced to 15168 bytes for vmx on my setup when building the kernel with kvmconfig.

README
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.
