set_memory_ro(), set_memory_nx(), set_memory_x() and other helps
can fail an return an error. In that case the memory might not be
protected as expected and the module loading has to be aborted to
avoid security issues.
Check return value of all calls to set_memory_XX() and handle
error if any.
It's a bit puzzling to see a call to module_enable_nx() followed by a
call to module_enable_x(). This is because one applies on text while
the other applies on data.
Change name to make that more clear.

Potentially-blocking splice_reads are allowed for normal filesystems

Hi!
As it stands, splice(file -> pipe):
1. locks the pipe,
2. does a read from the file,
3. unlocks the pipe.
When the file resides on a normal filesystem, this isn't an issue
because the filesystem has been defined as trusted by root having
mounted it.
But when the file is actually IPC (FUSE)

Use netmem_ref instead of page in skb_frag_t. Currently netmem_ref
is always a struct page underneath, but the abstraction allows efforts
to add support for skb frags not backed by pages.
There is unfortunately 1 instance where the skb_frag_t is assumed to be
a bio_vec in kcm. For this case, add
Add the netmem_ref type, an abstraction for network memory.
To add support for new memory types to the net stack, we must first
abstract the current memory type. Currently parts of the net stack
use struct page directly:
- page_pool
- drivers
- skb_frag_t
Originally the plan was to reuse struct
Minor fix for virtio: code wanting to access the fields inside an skb
frag should use the skb_frag_*() helpers, instead of accessing the
fields directly. This allows for extensions where the underlying
memory is not a page.
