Marc Zyngier f82030a586 KVM: arm64: Fix debug register indexing
commit cb853ded1d25e5b026ce115dbcde69e3d7e2e831 upstream.

Commit 03fdfb2690 ("KVM: arm64: Don't write junk to sysregs on
reset") flipped the register number to 0 for all the debug registers
in the sysreg table, hereby indicating that these registers live
in a separate shadow structure.

However, the author of this patch failed to realise that all the
accessors are using that particular index instead of the register
encoding, resulting in all the registers hitting index 0. Not quite
a valid implementation of the architecture...

Address the issue by fixing all the accessors to use the CRm field
of the encoding, which contains the debug register index.

Fixes: 03fdfb2690 ("KVM: arm64: Don't write junk to sysregs on reset")

README

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.
