Problem:
There are 2 types of wrong kasan report after merge change of
save wasted slab.
1, slab-out-of-bounds, which is caused by krealloc set shadow
memory out-of-range, since tail of page was freed.
2, use-after-free, which is caused by kasan_free_pages called
after a page freed. Because this function already called in
free_page, so it marked shadow memory twice.
Solution:
1, make shadow do not out of range if a tail page was freed and
been realloc again.
2, remove call of kasan_free_pages.

[Estelle] Enable top/bottom color clamping
Modifies amvecm's color clipping to allow either the lower or upper
limit to be set. This sets clipping registers that hold the top and
bottom 10-bit clipping values for each color channel.
This does not cause the artifacts that we've been seeing while trying
enable the gamma tables.
Usage (set a clip of 32/255):
echo 20080020 > /sys/class/amvecm/color_bottom

Problem:
stop endpoint race
Solution:
A counter was used to find out if the stop endpoint completion raced with
the stop endpoint timeout timer. This was needed in case the stop ep
completion failed to delete the timer as it was running on anoter cpu.
The EP_STOP_CMD_PENDING flag was not enough as a new stop endpoint command
may be queued between the command completion and timeout function, which
would set the flag back.
Instead of the separate counter that was used we can detect the race by
checking both the STOP_EP_PENDING flag and timer_pending in the timeout
function.
