commit811154e234upstream. When handling ESR_ELx_EC_WATCHPT_LOW, far_el2 member of struct kvm_vcpu_fault_info will be copied to far member of struct kvm_debug_exit_arch and exposed to the userspace. The userspace will see stale values from older faults if the fault info does not get populated.

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.
