A lot of this again is scattered across the various hardware

platforms has been gone through by Marvell Berlin maintainers and
added most options they need to run on their hardware. Broadcom NSP
is also added there, and the new Atmel SAMA5D2 (added last release).
Rockchip also has display and other devices supported in that config.

"As we've enabled multiplatform kernels on ARM, and greatly done away

Many of them go in through other driver trees, but we still have

that might be shared between ARM and ARM64 (or just in general makes
sense to not have under the architecture directory).
This branch contains mostly such code:
- Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to
communicate with power management blocks on these SoCs for use by
clock, regulator and bus frequency drivers.
- Allwinner Reduced Serial Bus driver, again used to communicate with
PMICs.
- Drivers for ARM's SCPI (System Control Processor). Not to be
confused with PSCI (Power State Coordination Interface). SCPI is
used to communicate with the assistant embedded cores doing power
management, and we have yet to see how many of them will implement
this for their hardware vs abstracting in other ways (or not at all
like in the past).

also includes an update of PSCI to interface version 1.0.

Fix alloc_node_mem_map() to work on ia64 again
In commit
a1c34a3bf00a ("mm: Don't offset memmap for flatmem") Laura
fixed a problem for Srinivas relating to the bottom 2MB of RAM on an ARM
IFC6410 board.
One small wrinkle on ia64 is that it allocates the node_mem_map earlier
in arch code, so it skips the block of code where "offset" is
initialized.
Move initialization of start and offset before the check for the
node_mem_map so that they will always be available in the latter part of
the function.

contained to the NFIT driver and is passing unit tests. The coredump
support is straightforward and was looked over by Jeff. All of it has

Summary:
- Add support for the ACPI 6.0 NFIT hot add mechanism to process
updates of the NFIT at runtime.

fs/binfmt_elf_fdpic.c: provide NOMMU loader for regular ELF binaries
The ELF binary loader in binfmt_elf.c requires an MMU, making it
impossible to use regular ELF binaries on NOMMU archs. However, the FDPIC
ELF loader in binfmt_elf_fdpic.c is fully capable as a loader for plain
ELF, which requires constant displacements between LOAD segments, since it
already supports FDPIC ELF files flagged as needing constant displacement.
This patch adjusts the FDPIC ELF loader to accept non-FDPIC ELF files on
NOMMU archs. They are treated identically to FDPIC ELF files with the
constant-displacement flag bit set, except for personality, which must
match the ABI of the program being loaded; the PER_LINUX_FDPIC personality
controls how the kernel interprets function pointers passed to sigaction.
Files that do not set a stack size requirement explicitly are given a
default stack size (matching the amount of committed stack the normal ELF
loader for MMU archs would give them) rather than being rejected; this is
necessary because plain ELF files generally do not declare stack
requirements in theit program headers.
Only ET_DYN (PIE) format ELF files are supported, since loading at a fixed
virtual address is not possible on NOMMU.
This patch was developed and tested on J2 (SH2-compatible) but should
be usable immediately on all archs where binfmt_elf_fdpic is
available. Moreover, by providing dummy definitions of the
elf_check_fdpic() and elf_check_const_displacement() macros for archs
which lack an FDPIC ABI, it should be possible to enable building of
binfmt_elf_fdpic on all other NOMMU archs and thereby give them ELF
binary support, but I have not yet tested this.
The motivation for using binfmt_elf_fdpic.c rather than adapting
binfmt_elf.c to NOMMU is that the former already has all the necessary
code to work properly on NOMMU and has already received widespread
real-world use and testing. I hope this is not controversial.
I'm not really happy with having to unset the FDPIC_FUNCPTRS
personality bit when loading non-FDPIC ELF. This bit should really
reset automatically on execve, since otherwise, executing non-ELF
binaries (e.g. bFLT) from an FDPIC process will leave the personality
in the wrong state and severely break signal handling. But that's a
separate, existing bug and I don't know the right place to fix it.

kernel.h: make abs() work with 64-bit types
For 64-bit arguments, the abs macro casts it to an int which leads to
lost precision and may cause incorrect results. To deal with 64-bit
types abs64 macro has been introduced but still there are places where
abs macro is used incorrectly.
To deal with the problem, expand abs macro such that it operates on s64
type when dealing with 64-bit types while still returning long when
dealing with smaller types.
This fixes one known bug (per John):
The internal clocksteering done for fine-grained error correction uses a
: logarithmic approximation, so any time adjtimex() adjusts the clock
: steering, timekeeping_freqadjust() quickly approximates the correct clock
: frequency over a series of ticks.
:
: Unfortunately, the logic in timekeeping_freqadjust(), introduced in commit
:
dc491596f639438 (Rework frequency adjustments to work better w/ nohz),
: used the abs() function with a s64 error value to calculate the size of
: the approximated adjustment to be made.
:
: Per include/linux/kernel.h: "abs() should not be used for 64-bit types
: (s64, u64, long long) - use abs64()".
:
: Thus on 32-bit platforms, this resulted in the clocksteering to take a
: quite dampended random walk trying to converge on the proper frequency,
: which caused the adjustments to be made much slower then intended (most
: easily observed when large adjustments are made).

from the line "GNU Library General Public License"; and replace the word
"library" with "program" in several other places.
The copyright should match the GPL v2 description as specified in the GNU
license found here: http://www.gnu.org/licenses/gpl-2.0.html
It should also match this copyright text with the correct MODULE_LICENSE

In this case "GNU Public License v2 or later" is linked with "GPL".
