Subject: x86/paravirt: Remove const mark from x86_hyper_xen_hvm variable
X-Git-Tag: v5.3-rc1~27^2~3
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=cc8f3b4dd2eb859bc57187ccd94b5cd715d9cfba;p=linux.git

x86/paravirt: Remove const mark from x86_hyper_xen_hvm variable

.. as "nopv" support needs it to be changeable at boot up stage.

Checkpatch reports warning, so move variable declarations from
hypervisor.c to hypervisor.h
