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 don't 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 during
run time.

PD#SWPL-1773
Problem:
After adding optimization of vmap stack, we can found stack usage
of each functions when handle vmap fault. From test log we see some
functions using large stack size which over 256bytes. Especially
common call path from fs. We need to optimize stack usage of these
functions to reduce stack fault probability and save stack memory
usage.
Solution:
1. remove CONFIG_CC_STACKPROTECTOR_STRONG and set STACKPROTECTOR to
NONE. This can save stack usage add by compiler for most functions.
Kernel code size can also save over 1MB.
2. Add some noinline functions for android_fs_data rw trace calls. In
these trace call it allcated a 256 bytes local buffer.
3. Add a wrap function for mem abort handler. By default, it defined a
siginfo struct(size over 100 bytes) in local but only used when fault
can't be handled.
4. reduce cached page size for vmap stack since probability of page
fault caused by stack overflow is reduced after function stack usage
optimized.
Monkey test show real stack usage ratio compared with 1st vmap
implementation reduced from 35% ~ 38% to 26 ~ 27%. Which is very
close to 25%, theory limit.

Problem:
On arm64, thread stack is 16KB for each task. If running task number
is large, this type of memory may over 40MB. It's a large amount on
small memory platform. But most case thread only use less 4KB stack.
It's waste of memory and we need optimize it.
Solution:
1. Pre-allocate a vmalloc address space for task stack;
2. Only map 1st page for stack and handle page fault in EL1
when stack growth triggered exception;
3. handle stack switch for exception.
