regmap: Changes for v4.3
This has been a busy release for regmap. By far the biggest set of
changes here are those from Markus Pargmann which implement support for
block transfers in smbus devices. This required quite a bit of
refactoring but leaves us better able to handle odd restrictions that
controllers may have and with better performance on smbus.
Other new features include:
- Fix interactions with lockdep for nested regmaps (eg, when a device
using regmap is connected to a bus where the bus controller has a
separate regmap). Lockdep's default class identification is too
crude to work without help.
- Support for must write bitfield operations, useful for operations
which require writing a bit to trigger them from Kuniori Morimoto.
- Support for delaying during register patch application from Nariman
Poushin.
- Support for overriding cache state via the debugfs implementation
from Richard Fitzgerald.

libnvdimm for 4.3:
1/ Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
mechanism for adding device-driver-discovered memory regions to the
kernel's direct map. This facility is used by the pmem driver to
enable pfn_to_page() operations on the page frames returned by DAX
('direct_access' in 'struct block_device_operations'). For now, the

Pull libnvdimm updates from Dan Williams:
"This update has successfully completed a 0day-kbuild run and has
appeared in a linux-next release. The changes outside of the typical
drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
the introduction of ZONE_DEVICE + devm_memremap_pages().
Summary:
- Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
mechanism for adding device-driver-discovered memory regions to the
kernel's direct map.
This facility is used by the pmem driver to enable pfn_to_page()
operations on the page frames returned by DAX ('direct_access' in
'struct block_device_operations').
For now, the 'memmap' allocation for these "device" pages comes
from "System RAM". Support for allocating the memmap from device
memory will arrive in a later kernel.
- Introduce memremap() to replace usages of ioremap_cache() and
ioremap_wt(). memremap() drops the __iomem annotation for these
mappings to memory that do not have i/o side effects. The

Mostly this is just clean ups and micro optimizations.
The changes with more meat are:
o Allowing the trace event filters to filter on CPU number and process ids
o Two new markers for trace output latency were added
(10 and 100 msec latencies)
o Have tracing_thresh filter function profiling time
I also worked on modifying the ring buffer code for some future
work, and moved the adding of the timestamp around. One of my changes
caused a regression, and since other changes were built on top of it
and already tested, I had to operate a revert of that change. Instead
of rebasing, this change set has the code that caused a regression
as well as the code to revert that change without touching the other
changes that were made on top of it.

xen: limit memory to architectural maximum
When a pv-domain (including dom0) is started it tries to size it's p2m list according to the maximum possible memory amount it ever can achieve. Limit the initial maximum memory size to the architectural limit of the hardware in order to avoid overflows during remapping of memory. This problem will occur when dom0 is started with an initial memory size being a multiple of 1GB, but without specifying it's maximum memory size. The kernel must be configured without CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen.

xen: avoid another early crash of memory limited dom0
Commit b1c9f169047b ("xen: split counting of extra memory pages...")
introduced an error when dom0 was started with limited memory occurring
only on some hardware.
The problem arises in case dom0 is started with initial memory and
maximum memory being the same. The kernel must be configured without
CONFIG_XEN_BALLOON_MEMORY_HOTPLUG for the problem to happen. If all
of this is true and the E820 map of the machine is sparse (some areas
are not covered) then the machine might crash early in the boot
process.
An example E820 map triggering the problem looks like this:

In this case the area a0000-dffff isn't present in the map. This will
confuse the memory setup of the domain when remapping the memory from
such holes to populated areas.
To avoid the problem the accounting of to be remapped memory has to
count such holes in the E820 map as well.

xen: avoid early crash of memory limited dom0
Commit b1c9f169047b ("xen: split counting of extra memory pages...")
introduced an error when dom0 was started with limited memory.
The problem arises in case dom0 is started with initial memory and
maximum memory being the same and exactly a multiple of 1 GB. The
kernel must be configured without CONFIG_XEN_BALLOON_MEMORY_HOTPLUG
for the problem to happen. In this case it will crash very early
during boot due to the virtual mapped p2m list not being large
enough to be able to remap any memory:
(XEN) Freed 304kB init memory.

NFSv4: Respect the server imposed limit on how many changes we may cache
The NFSv4 delegation spec allows the server to tell a client to limit how much data it cache after the file is closed. In return, the server guarantees enough free space to avoid ENOSPC situations, etc. Prior to this patch, we assumed we could always cache aggressively after close. Unfortunately, this causes problems with servers that set the limit to 0 and therefore do not offer any ENOSPC guarantees. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com> |

Just a few cleanups for 4.3 merge window for the 9p file system.
I've gotten several more over the past week, but this group has been
in for-next for at least a couple of weeks so I figured I'd push them
first while I test the rest. Most of the ones not in this set are
bug-fixes anyways so I could hold them for rc1 if you'd rather they
see more time in for-next.

gotten several more over the past week, but this group has been in

rtc: s5m: fix to update ctrl register
According to datasheet, the S2MPS13X and S2MPS14X should update write buffer via setting WUDR bit to high after ctrl register is written. If not, ALARM interrupt of rtc-s5m doesn't happen first time when i use tools/testing/selftests/timers/rtctest.c test program and hour format is used to 12 hour mode in Odroid-XU3 board. One more issue is the RTC doesn't keep time on Odroid-XU3 board when i turn on board after power off even if RTC battery is connected. It can be solved as setting WUDR & RUDR bits to high at the same time after RTC_CTRL register is written. It's same with condition of only writing ALARM registers, so this is for only S2MPS14 and we should set WUDR & A_UDR bits to high on S2MPS13. I can't find any reasonable description about this like fix from datasheet, but can find similar codes from rtc driver source of hardkernel kernel and vendor kernel.

ARM: config: Switch PXA27x platforms to use PXA RTC driver
With the SA1100 and PXA RTC drivers be mutually exclusive and no longer sharing hardware, PXA27x/PXA3xx platforms must use the PXA RTC driver as the SA1100 platform device is no longer registered. This change should be almost transparent to userspace. Former users of pxa-rtc should be aware that 2 RTCs will be available on their kernels, rtc0 being sa1100-rtc and rtc1 being pxa-rtc. Any userspace relying on the fact that rtc0 was pxa-rtc should be fixed. As a consequence: - the first reboot after the switch will have the wrong time, - on dual boot platform where the other OS programs some logic into the sa1100 rtc IP, a lack of fix in userspace, ie. a kernel changing sa1100-rtc thinking it is pxa-rtc could have dire consequence, such as wiping the other OS data partition.
