Rule 11.8 states as following: "A cast shall not remove any `const' or `volatile' qualification from the type pointed to by a pointer". Function `__hvm_copy' in `xen/arch/x86/hvm/hvm.c' is a double-use function, where the parameter needs to not be const because it can be set for write or not. As it was decided a new const-only function will lead to more developer confusion than it's worth, this violation is addressed by deviating the function. All cases of casting away const-ness are accompanied with a comment explaining why it is safe given the other flags passed in; such comment is used by the deviation in order to match the appropriate function call. No functional change. Signed-off-by: Alessandro Zucchelli <alessandro.zucchelli@bugseng.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org>
