My Spectec SDW823 card oopsed when it was already inserted during boot.
When debugging this, I noticed that the card init was done in a seperate
workqueue which was only activated once in probe. After removing the
workqueue and calling the card init directly from probe, the OOPS went
away. It turned out this is the same OOPS which happened when removing
the card, so this seems possible now. Note: There is still a
not-understood card-removed event during boot, but at least it doesn't
crash anymore and the card will be re-probed right away.

* updated Kconfig help text and dependencies
* added TODO
* removed two __DATE__ and __TIME__ printouts to allow reproducible builds
* added to staging main Kconfig + Makefile

In ll_readpage and ll_write_begin, it needs to find out the cl_env
and cl_io, a.k.a ll_cl_context, when the IO is initialized. It used
to call cl_env_get() to figure it out but turned out to be contended
if multiple threads are doing IO.

In this patch, a per open file ll_cl_context cache is created. When
IO type of CIT_READ, CIT_WRITE and CIR_FAULT is initialized, it will
add a ll_cl_context into the cache maintained in ll_file_data. In this
case, the ll_cl_context can be found in ll_readpage and ll_write_begin
later.

Commit b8a7a3a6 change get_acl() for posix xattr to always cache
the ACL which increases the reference count. That reference count
can be reduced by have ll_get_acl() call forget_cached_acl() which
it wasn't. When an inode gets deleted by Lustre the POSIX ACL
reference count is tested to ensure its 1 and if not produces an error.
Since forget_cached_acl() was not called Lustre started to complain.
This patch changes ll_get_acl() to call forget_cached_acl().

 - Fix userspace crash when syscalls access invalid unaligned userspace

  KEYS: Add placeholder for KDF usage with DH

The /dev/ptmx device node is changed to lookup the directory entry "pts"
in the same directory as the /dev/ptmx device node was opened in.  If
there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx
uses that filesystem.  Otherwise the open of /dev/ptmx fails.

The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that
userspace can now safely depend on each mount of devpts creating a new
instance of the filesystem.

Each mount of devpts is now a separate and equal filesystem.

Reserved ttys are now available to all instances of devpts where the
mounter is in the initial mount namespace.

A new vfs helper path_pts is introduced that finds a directory entry
named "pts" in the directory of the passed in path, and changes the
passed in path to point to it.  The helper path_pts uses a function
path_parent_directory that was factored out of follow_dotdot.

In the implementation of devpts:
 - devpts_mnt is killed as it is no longer meaningful if all mounts of
   devpts are equal.
 - pts_sb_from_inode is replaced by just inode->i_sb as all cached
   inodes in the tty layer are now from the devpts filesystem.
 - devpts_add_ref is rolled into the new function devpts_ptmx.  And the
   unnecessary inode hold is removed.
 - devpts_del_ref is renamed devpts_release and reduced to just a
   deacrivate_super.
 - The newinstance mount option continues to be accepted but is now
   ignored.

In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as
they are never used.

Documentation/filesystems/devices.txt is updated to describe the current
situation.

This has been verified to work properly on openwrt-15.05, centos5,
centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3,
ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1,
slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01.  With the
caveat that on centos6 and on slackware-14.1 that there wind up being
two instances of the devpts filesystem mounted on /dev/pts, the lower
copy does not end up getting used.
