Subject: xen/hypercall: Allow HYPERVISOR_console_write to take a const string
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=19f3aaef68d529d0a037150b1c26f3b959dfbdfd;p=people%2Fjulieng%2Ffreebsd.git

xen/hypercall: Allow HYPERVISOR_console_write to take a const string

The hypercall console write won't modify the string. It's safe to put a const
here.
