Problem:
When driver/kernel call kmalloc with large size, memory may waste
if size is not equal to 2^n. For example, driver call kmalloc with
size 129KB, kmalloc will allocate a 256KB memory block to caller.
Then 127kb memory will be wasted if this caller do not free it.
Solution:
Free tail of slab memory if size is not match to 2^n. This change
can save about 900KB memory after boot, and more than 100KB durning
runtime.

Problem:
memory reclaim process is usually do when first allocate failed from buddy.
This will cause some process crash especially when memory is low, because
there is not enough time to do reclaim process.
Solution:
try to wake up kswapd process to reclaim memory if free memory is less
than high water mark. After apply this change, free memory is usually
keeps high than high_water mark.
