The device tree contains initial support for the Xiaomi Redmi 2 with:

- eMMC/SD card
- Buttons
- Vibrator
- WiFi/Bluetooth (WCNSS)
- USB
Note that the Xiaomi Redmi 2 is available in variants with different
names (e.g. Redmi 2 Prime, Redmi 2 Pro, ...). As far as I know the main
difference between those is the amount of RAM and supported LTE bands.
This difference is automatically handled by bootloader/modem firmware

mm/rmap: fix old bug: munlocking THP missed other mlocks
The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)
