The initial values for fpstate::xfd differ between guest and host fpstates. Currently, the initial values are passed as an argument to __fpstate_reset(). But, __fpstate_reset() already assigns different default features and sizes based on the type of fpstates (i.e., guest or host). So, handle fpstate::xfd in a similar way to highlight the differences in the initial xfd value between guest and host fpstates Suggested-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Chao Gao <chao.gao@intel.com> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Reviewed-by: John Allen <john.allen@amd.com> Link: https://lore.kernel.org/all/aBuf7wiiDT0Wflhk@google.com/ Link: https://lore.kernel.org/all/20250522151031.426788-5-chao.gao%40intel.com
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 reStructuredText 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.
