Add the nvram_size() function to those PowerPC platforms that don't already
have one: CHRP and PowerMac. This means that the ppc_md.nvram_size()
function can be used to implement arch_nvram_ops.get_size()

Since we are addressing inconsistencies here, also rename chrp_nvram_read
and chrp_nvram_write, which break the naming convention used across
PowerPC platforms for NVRAM accessor functions.

Add the powerpc-specific sync() method to struct nvram_ops and implement
the corresponding ioctl in the nvram module. This allows the nvram module
to replace the generic_nvram module.

Signed-off-by: Finn Thain <fthain@telegraphics.com.au>

On PPC32, the IOC_NVRAM_SYNC ioctl call always returns 0, even for those
platforms that don't implement ppc_md.nvram_sync. This patch retains
that quirk. It might be better to return failure (which is what PPC64 does).

Changed since v1:
- Don't bother acquiring the mutex for unimplemented ioctls.

Different platforms and architectures offer different NVRAM sizes and
access methods. E.g. PPC32 has byte-at-a-time read/write functions whereas
PPC64 has byte-range read/write functions. Adopt the nvram_ops struct so
the nvram module can call such functions as are defined by the various
platforms and architectures.

The #ifdefs here restrict the procfs and checksumming code to those
architectures with PC-style RTC NVRAM. There may be a better place for
that code but it's an open question. See https://lkml.org/lkml/2015/2/3/22

The procfs code here, unless relevant to an ARM platform, could be moved to
arch/x86 (like the earlier patch does for m68k code) and the nvram ops
could be implemented and exported by the rtc-cmos driver instead. This
would eliminate these #ifdefs and almost eliminate the arch-specific code.

The generic NVRAM module, drivers/char/generic_nvram, implements a
/dev/nvram misc device. It is used only by 32-bit PowerPC platforms and
isn't generic enough to be more widely used.

The RTC NVRAM module, drivers/char/nvram, also implements a /dev/nvram
misc device. It is used by x86, ARM and m68k.

The former module cannot be used on x86, ARM or m68k because it
cannot co-exist with the latter module, partly due to the Kconfig logic.

It is possible to modify the modules so that one kernel binary could
have either, neither or both. However, automatically loading the
appropriate module is then impossible; if both provide the
char-major-10-144 alias then the wrong module will end up being loaded.
Hence a multi-platform kernel binary needs a single generic nvram module
with alias char-major-10-144.

Therefore, drivers/char/nvram.c should be made more generic and the
arch-specific code therein should be moved to a more appropriate
place under arch/. Also, drivers/char/generic_nvram.c should be removed
to reduce code duplication.

In this patch series, Atari-specific code is moved from the nvram module
to arch/m68k/atari. More arch-specific code in the nvram module could
be moved, probably to arch/x86, but it is difficult to determine just
what code is relevant to ARM platforms and what code is x86-only.

In addressing code duplication, this patch series removes three
inconsistent /dev/nvram misc device implementations. One of these,
drivers/macintosh/nvram.c is entirely unused already. The other two,
drivers/char/generic_nvram.c and the misc device implementation in
arch/powerpc/kernel/nvram_64.c, are replaced by drivers/char/nvram.c.

A benefit of this work is better consistency -- between PPC32 and PPC64
as well as between PPC_PMAC and MAC. This new uniformity does have
implications for userspace, that is, some error codes for some ioctl calls
become consistent on all PowerPC platforms.

The drivers/char/nvram module becomes sufficiently generic to be useful
to other platforms and architectures, besides those with "CMOS" RTC. At the
end of this patch series the module is adopted by the m68k Mac port, which
already has PRAM access functions but lacks the /dev/nvram misc device.

This patch series has been compile-tested for arm, m68k, powerpc and x86.
The nvram and thinkpad_acpi modules were regression tested on a ThinkPad T43.
The /dev/nvram functionality was also regression tested on a G3 PowerMac.
The nvram module was also tested on a PowerBook 520 and Quadra 650.
Note that my testing doesn't cover PPC64 or Atari.

- Minor changes to patches 7, 15 and 20 as described in commit logs.
- Revised patches 21 and 24 to address comments from Geert.

Changes since v2:
- Dropped patch 1, "macintosh/nvram: Remove as unused", because it has
since been merged.
- Inserted a new patch, "m68k/mac: Use macros for RTC accesses not
magic numbers".
- Revised patches 21 and 23 to address comments from Geert.

Changes since v3:
- Split the patch, "m68k/atari: Move Atari-specific code out of
drivers/char/nvram.c", as suggested by Geert.
- Revised patches 11 and 25 to address comments from Geert.
- Minor change to patch 21 as described in commit log.

This SPI device is found at least on NXP LPC32XX ARM
family. It has 64 entry FIFO and is quite fast when
using only IRQ.
The driver uses generic SPI and OF frameworks to
minimize its size.
It is tested in HW (SPI flash with JFFS2).

+NXP LPC32XX SPI controller
+
+Required properties:
+- compatible : "nxp,lpc3220-spi"
+- reg : Offset and length of the register set for the device
+- interrupts : Should contain SPI controller interrupt
+- cs-gpios : should specify GPIOs used for chipselects.
+ The gpios will be referred to as reg = <index> in the SPI child nodes.
+
+SPI slave nodes must be children of the SPI master node and can
+contain the following properties.

+ spi-max-frequency = <hz>;
+ spi-cpol;
+ spi-cpha;

+ interrupts = <55 0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ num-cs = <1>;

Changes in v3:
- builtin-config.c: Add a config variable ’kmem.default’ with a default value into ‘struct default_configset’
which has default config variables and values.
- cmd_config(): Add a option ‘—global’ and ‘—local’ to enable config file location to be selected

Changes in v2:
- Renaming variables a more suitable name
1. ’—list-all' instead of '--all'
2. ’name' instead of 'subkey'
3. 'section, name, value' instead of 'given_section,subkey,value'
- Documentation/perf-config.txt: Correct small infelicities or typing errors in a perf-config documention.
- Documentation/perf-config.txt: Remove a part description of report.children because it was duplicated
in Documentation/callchain-overhead-calculation.txt
- builtin-config.c: Use a variable ’int actions’ instead of struct params which has ‘bool list_action’,
‘bool get_action’ and etc. , to simplify a branching statement for perf-config options
- builtin-config.c: Declaration a global variable ‘static struct default_configsets’ has config variables
with default values instead of using a 'util/PERFCONFIG-DEFAULT' file and remove functions merge()
and perse_key() to get perf config default values.
- normalize_value(): Add a function to normalize a value and check data type of it.
- cmd_config(): Simplify parsing arguments as arguments is just divided by '=' and then in front of '.' is a section,
between '.' and '=' is a name, and behind '=' is a value.
- show_all_config(): Print config variables ‘struct default_configsets’ haven't
- cmd_config(): Make a command ’perf config' without a option work as with a option ’—list’ instead of ‘—list-all’.

Taeung Song (5):
perf tools: Add 'perf-config' command
perf config: Add functions which can get or set perf config variables.
perf config: Add a option 'list-all' to perf-config.
perf config: Add a option 'remove' to perf-config.
perf config: Add ‘—system’ and ‘—global’ options to be able to select
which config file to be used.

Which config file is used is decided at only perf_config().
That's why a config file to be used can't be selected
among system and global config file when perf-config commands
get or set it. So add '--system' and '--global' options to select
which config file to be used when getting, setting or etc.

Below is the list of build error/warning regressions/improvements in
v4.2-rc2[1] compared to v4.1[2].

Summarized:
- build errors: +13/-53
- build warnings: +164/-278

JFYI, when comparing v4.2-rc2[1] to v4.2-rc1[3], the summaries are:
- build errors: +7/-5
- build warnings: +55/-48

As I haven't mastered kup yet, there's no verbose summary at
http://www.kernel.org/pub/linux/kernel/people/geert/linux-log/v4.2-rc2.summary.gz

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.

Commit 0e0da48dee8d ("parisc: mm: don't count preallocated pmds")
introduced a memory leak.

After this commit, the 'return' statement in pmd_free is executed in all
cases. Even for pmd that are not attached to the pgd.
So 'free_pages' can never be called anymore, leading to a memory leak.

This patch is *untested* as I don't have the hardware to test it.

This is just a guess based on the indentation, the comment in the code
and the commit log.

This series add GPT timer support for mt8173. This is based on v4.2-rc1
and Matthias' next branch (for dts parts).

The first 2 patches comes from 'Add SMP bringup support for mt65xx socs'
series [1]. I decide to move these 2 patches to this series, since it
is more relevent here. They are changed based on Matthias' and Daniel's
comments.

[1] http://lists.infradead.org/pipermail/linux-mediatek/2015-May/000714.html

Daniel Kurtz (1):
arm64: dts: mt8173: add timer node

Yingjoe Chen (4):
clocksource: mediatek: do not enable GPT_CLK_EVT when setup
clocksource: mediatek: Use GPT as sched clock source
arm64: mediatek: enable MTK_TIMER
clk: mediatek: add 13mhz clock for MT8173

If there are gced dirty pages and normal dirty pages in the mapping
of one inode, we might writeback them alternately with discontinuous
block address, resulting in low performance.

This patch introduces f2fs_write_cache_pages with codes copied from
write_cache_pages in mm/page-writeback.c.

In this function, we refactor flow with two steps:
1) writeback all cold type pages.
2) writeback all non-cold type pages.

By using this method, f2fs will writeback dirty pages with the same
temperature in bunch mode, it makes writeouted block being with
more continuous address, so they can be merged as much as possible
in f2fs bio cache, and also it will reduce the chance of submiting
small IO from block layer.

Test environment: 8g nokia sd card (very old sd card, but it shows
better effect when testing with this patch, and with a 32g kingston
sd card, I didn't see much more improvement).

Test step:
1. touch testfile;
2. truncate -s 512K testfile;
3. write all pages with odd index;
4. trigger gc by ioctl;
5. write all pages with even index;
6. time fsync testfile.

real 0m0.402s
user 0m0.000s
sys 0m0.000s

after:

user 0m0.004s
sys 0m0.004s

With cost-benifit method, background gc will consider old section with
fewer valid blocks as candidate victim, these old blocks in section will
be treated as cold data, and laterly will be moved into cold segment.

But if the gcing page is attached by user through buffered or mmaped
write, we should reset the page as non-cold one, because this page may
have more opportunity for further updating.

So fix to add clearing code for the missed 'mmap' case.

Previously, since 'commit 4531929e3922 ("f2fs: move grabing orphan
pages out of protection region")' was committed, in write_orphan_inodes(),
we will grab all meta page in a batch before we use them under spinlock,
so that we can avoid large time delay of grabbing meta pages under
spinlock.

Now, 'commit d6c67a4fee86 ("f2fs: revmove spin_lock for
write_orphan_inodes")' remove the spinlock in write_orphan_inodes,
so there is no issue we describe above, we'd better recover to move
the grab operation to original place for readability.
