Convert the WARN in tdp_mmu_iter_cond_resched() that the iterator hasn't already yielded to a KVM_MMU_WARN_ON() so the code is compiled out for production kernels (assuming production kernels disable KVM_PROVE_MMU). Checking for a needed reschedule is a hot path, and KVM sanity checks iter->yielded in several other less-hot paths, i.e. the odds of KVM not flagging that something went sideways are quite low. Furthermore, the odds of KVM not noticing *and* the WARN detecting something worth investigating are even lower.

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.
