register_module_notifier() does have "dummy" version but what
would I pass to it. It makes
s/textmem/execmem/ (also in long description)
will hold sending a new version as not a functional issue, will fix

Tracing with kprobes while running a monolithic kernel is currently

the kernel module allocator.
Introduce alloc_textmem() and free_textmem() for allocating executable
memory. If an arch implements these functions, it can
