H A Dgdb_machdep.cdiff 2337dc6430a1a169987955b6ee27bebf950f5491 Tue Mar 20 18:43:50 CET 2018 Konstantin Belousov <kib@FreeBSD.org> Provide KPI for handling of rw/ro kernel text.

This is a pure syntax patch to create an interface to enable and later
restore write access to the kernel text and other read-only mapped
regions. It is in line with e.g. vm_fault_disable_pagefaults() by
allowing the nesting.
