PD#150206: mm: forward memory reclaim process
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. This change 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.

PD#150194: mm: update cma policy and debug sysfs
1. For movable memory, using CMA first, this can help to avoid
low memory issue and driver can't allocate pages issue;
2. change /proc/slabinfo sysfs with total size print of each slab;
3. change /proc/pagetypeinfo with toatal pages of each migrate type;
4. add statistics for free pages of each migrate type, and show in
echo m > /proc/sysrq-trigger.

PD#145456: Support RPMB shared secret provisioning [2/2]
[Problem]
RPMB requires a shared secret between host (AP) and device (eMMC flash)
in order to perform HMAC authentication.
[Solution]
This commit provides a special reboot mode, reboot rpmbp, to securely
provision the shared secret into eMMC flash device.
[Test]
Tested on GXL reference board P212. Passed.

PD#146628: crypto update for axg
1. KEY_IV now can only read 16 bytes a time
2. DES is completely disabled and TDES with three identical keys are
also disabled. This creates a potential hole in TDES driver, and
thus TDES support is removed from dts in axg

PD#150373: gcc: add options to limit large object and stack usage
We should restrict limit large size of global object allocated in
driver code to reduce size of .data/.bss/.rodata sections. Also,
large array/many variables declared in a function is not allowed,
this behavior may cause kernel stack overflow especially in IRQ
context or recursion calls.
Right now we just set a very high limit in order to pass comiple.
Final target is to limit:
1. large global object size should not over 4096 bytes, a page size;
2. stack usage of each function should not over 256 bytes.
If your global object is larger than a page size, we advise allocate
it as a static pointer, and allocate it's memory during probe stage.
