Pull mount fixes from Al Viro:
 "Several mount-related fixes"

* tag 'pull-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  userns and mnt_idmap leak in open_tree_attr(2)

  replace collect_mounts()/drop_collected_mounts() with a safer variant

When loading a module, as long as the module has memory allocation
operations, kmemleak produces a false positive report that resembles the
following:

unreferenced object (percpu) 0x7dfd232a1650 (size 16):
  comm "modprobe", pid 1301, jiffies 4294940249
  hex dump (first 16 bytes on cpu 2):

    el0t_64_sync_handler+0x10c/0x138
    el0t_64_sync+0x1ac/0x1b0

This is because the module can only indirectly reference
alloc_tag_counters through the alloc_tag section, which misleads kmemleak.

However, we don't have a kmemleak ignore interface for percpu allocations
yet.  So let's create one and invoke it for tag->counters.

We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

Initialize unique name for amdisp i2c adapter, which is used
in the platform driver to detect the matching adapter for
i2c_client creation.

Add definition of amdisp i2c adapter name in a new header file
(include/linux/soc/amd/isp4_misc.h) as it is referred in different
driver modules.
