[ Upstream commitc7785d85b6] If the parameter flush is set, zap_gfn_range() would flush remote tlb when yield, then tlb flush is not needed outside. So use the return value of zap_gfn_range() directly instead of OR on it in kvm_unmap_gfn_range() and kvm_tdp_mmu_unmap_gfn_range().

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.
