bpf, arm64: bpf trampoline for arm64
e85501c 
Add bpf trampoline support for arm64. Most of the logic is the same as
x86.

fentry before bpf trampoline hooked:
 mov x9, x30
 nop

fentry after bpf trampoline hooked:
 mov x9, x30
 bl  <bpf_trampoline>

Tested on qemu, result:
 #18  bpf_tcp_ca:OK
 #51  dummy_st_ops:OK
 #55  fentry_fexit:OK
 #56  fentry_test:OK
 #57  fexit_bpf2bpf:OK
 #58  fexit_sleep:OK
 #59  fexit_stress:OK
 #60  fexit_test:OK
 #67  get_func_args_test:OK
 #68  get_func_ip_test:OK
 #101 modify_return:OK

The reason was that the code that maps the ring buffer pages to user space
has:

	page = virt_to_page((void *)cpu_buffer->subbuf_ids[s]);

And uses that in:

	vm_insert_pages(vma, vma->vm_start, pages, &nr_pages);

But virt_to_page() does not work with vmap()'d memory which is what the
persistent ring buffer has. It is rather trivial to allow this, but for
now just disable mmap() of instances that have their ring buffer from the
reserve_mem option.

If an mmap() is performed on a persistent buffer it will return -ENODEV
just like it would if the .mmap field wasn't defined in the
file_operations structure.

drm/amd/display: Fix slab-use-after-free in hdcp
be593d9 
The HDCP code in amdgpu_dm_hdcp.c copies pointers to amdgpu_dm_connector
objects without incrementing the kref reference counts. When using a
USB-C dock, and the dock is unplugged, the corresponding
amdgpu_dm_connector objects are freed, creating dangling pointers in the
HDCP code. When the dock is plugged back, the dangling pointers are
dereferenced, resulting in a slab-use-after-free:

Fix this by properly incrementing and decrementing the reference counts
when making and deleting copies of the amdgpu_dm_connector pointers.
