- Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.
- Wait for a vCPU to come online prior to executing a vCPU ioctl to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that

Merge tag 'kvm-x86-vcpu_array-6.14' of https://github.com/kvm-x86/linux into HEAD
KVM vcpu_array fixes and cleanups for 6.14:
- Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug
where KVM would return a pointer to a vCPU prior to it being fully online,
and give kvm_for_each_vcpu() similar treatment to fix a similar flaw.
- Wait for a vCPU to come online prior to executing a vCPU ioctl to fix a
bug where userspace could coerce KVM into handling the ioctl on a vCPU that
isn't yet onlined.
- Gracefully handle xa_insert() failures even though such failuires should be

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.
