PMI8996 is *almost* the same hardware as PMI8994, say for some annoyances:

- Boards equipped with PMI8996 now have to include pmic-id (which wasn't the
case before)

- Different qpnp-ibb-discharge-resistor value (will be addressed after LABIBB
is introduced)

- Different inhibit-derating-ua value (will be addressed after BCL is
introduced)

- Different ramp_up_step value (will be addressed after [if?] QPNP Flash LED
is introduced)

This DTSI is supposed to be included >>ON TOP OF<< pmi8994.dtsi, like this:

-- msm8996-nice-device.dts --
\#include "pmi8994.dtsi"
\#include "pmi8996.dtsi"

or more likely like this:

-- msm8996-some-phone.dts --
\#include "msm8996.dtsi"
...
\#include "pmi8994.dtsi"

-- msm8996-pmi8996-some-phone.dts --
\#include "msm8996-some-phone.dts"
\#include "pmi8996.dtsi"

ones, instead of what would be three (device base + pmi8994 + pmi8996)

Also the USB-portB is used as the USB emergency

The Xiaomi Redmi 2 is a MSM8916 smartphone that was made by Wingtech
(codename: wt88047). It's fairly similar to the other MSM8916 devices.

The device tree contains initial support for the Xiaomi Redmi 2 with:
  - UART (untested, probably available via some test points)
  - 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
so there is no need for separate device trees.

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)

   - Plug leaks in scandir() returned dirent entries in 'perf test' when
     sorting the shell tests.

   - Fix --task and --stat with pipe input in 'perf report'.

   - Fix 'perf probe' use of debuginfo files by build id.

   - If a DSO has both dynsym and symtab ELF sections, read from both
     when loading the symbol table, fixing a problem processing Fedora
     32 glibc DSOs.

  Libraries:

   - Add grouping of events to libperf, from code in tools/perf,
     allowing libperf users to use that mode.

  Misc:

   - Filter plt stubs from the 'perf probe --functions' output.

   - Update UAPI header copies for asound, DRM, mman-common.h and the
     ones affected by the quotactl_fd syscall"

Commit dbbee9d5 ("mm/page_alloc: convert per-cpu list protection to
local_lock") folded in a workaround patch for pahole that was unable to
deal with zero-sized percpu structures.

A superior workaround is achieved with commit a0b8200d ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").

This patch reverts the dummy field and the pahole version check.
