simple as possible.
struct rt5645_eq_param_s {
unsigned short reg;

It supports the variant length of the HWEQ parameters that are required.
We add the validating function in the function "rt5645_hweq_put" of the
ALSA binary control to avoid the user that puts the invalid parameters.
In the HWEQ enable function of speaker event, we also add the validating
function to prevent that the invalid parameters are applied to codec.
The HWEQ parameters should be controlled by DAPM for a specific sequence,
so the parameters will be applied to the codec in the speaker power up

Mapping an image with a long parent chain (e.g. image foo, whose parent
is bar, whose parent is baz, etc) currently leads to a kernel stack
overflow, due to the following recursion in the reply path:

  rbd_osd_req_callback()
    rbd_obj_request_complete()
      rbd_img_obj_callback()
        rbd_img_parent_read_callback()

Limit the parent chain to 16 images, which is ~5K worth of stack.  When
the above recursion is eliminated, this limit can be lifted.

lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y

When the kernel compiled with KASAN=y, GCC adds redzones for each
variable on stack.  This enlarges function's stack frame and causes:

'warning: the frame size of X bytes is larger than Y bytes'

The worst case I've seen for now is following:

   ../net/wireless/nl80211.c: In function `nl80211_send_wiphy':
   ../net/wireless/nl80211.c:1731:1: warning: the frame size of 5448 bytes is larger than 2048 bytes [-Wframe-larger-than=]

That kind of warning becomes useless with KASAN=y.  It doesn't
necessarily indicate that there is some problem in the code, thus we
should turn it off.

(The KASAN=y stack size in increased from 16k to 32k for this reason)

mm: make sendfile(2) killable

Currently a simple program below issues a sendfile(2) system call which
takes about 62 days to complete in my test KVM instance.

        int fd;
        off_t off = 0;

        fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644);
        ftruncate(fd, 2);
        lseek(fd, 0, SEEK_END);
        sendfile(fd, fd, &off, 0xfffffff);

Now you should not ask kernel to do a stupid stuff like copying 256MB in
2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin
should have a way to stop you.

We actually do have a check for fatal_signal_pending() in
generic_perform_write() which triggers in this path however because we
always succeed in writing something before the check is done, we return
value > 0 from generic_perform_write() and thus the information about
signal gets lost.

Fix the problem by doing the signal check before writing anything.  That
way generic_perform_write() returns -EINTR, the error gets propagated up
and the sendfile loop terminates early.

kmod: don't run async usermode helper as a child of kworker thread

call_usermodehelper_exec_sync() does fork() + wait() with "unignored"
SIGCHLD.  What we have missed is that this worker thread can have other
children previously forked by call_usermodehelper_exec_work() without
UMH_WAIT_PROC.  If such a child exits in between it becomes a zombie
because auto-reaping only works if SIGCHLD is ignored, and nobody can
reap it (unless/until this worker thread exits too).

Change the !UMH_WAIT_PROC case to use CLONE_PARENT.

Note: this is only first step.  All PF_KTHREAD tasks, even created by
kernel_thread() should have ->parent == kthreadd by default.
