The autocalibration is separated in two bits to set in Oscillator
Control register (0x1c) :
- OSEL bit to select the oscillator type (XT or RC).
- ACAL bit to select the autocalibration type.
These functionnalities are exported in sysfs entries : "oscillator"
and "autocalibration". Respectively, the values are "xtal" for XT
oscillator and "rc" for RC oscillator and 0 to disable the
autocalibration cycle, 512 for a 512 seconds autocalibration cycle
and 1024 for a cycle of 1024 seconds.
Examples :
Set to XT Oscillator
echo xtal > /sys/class/rtc/rtc0/device/oscillator
Activate an autocalibration every 512 seconds
echo 512 > /sys/class/rtc/rtc0/device/autocalibration

The rv8803 has a 60µs window where it will not answer on the i2c bus.
It also means there will be no ack for the communication. Make sure
communication is tried multiple times when this happens (the i2c subsystem
mandates -ENXIO is that case but the number of retries is host specific).
The critical parts are the probe function and the alarm callback so make
sure we handle the failure there.

skb_len needs to be skb_headlen(skb) in bcmgenet_xmit_single().
Fragmented skbs can have only Ethernet + IP + TCP headers (14+20+20=54 bytes)
in the linear buffer, followed by the rest in fragments. Bumping skb_len to
ETH_ZLEN would be incorrect for this case, as it would introduce garbage
between TCP header and the fragment data.
This also works with regular/non-fragmented small packets < ETH_ZLEN bytes.
Successfully tested this on GENETv3 with 42-byte ARP frames.
For testing, I used:
ethtool -K eth0 tx-checksum-ipv4 off
ethtool -K eth0 tx-checksum-ipv6 off
echo 0 > /proc/sys/net/ipv4/tcp_timestamps

1. Add bytes_compl local variable to __bcmgenet_tx_reclaim() to collect
transmitted bytes. dev->stats updates can then be moved outside the
while-loop. bytes_compl is also needed for future BQL support.
2. When bcmgenet device uses Tx checksum offload, each transmitted skb
gets an extra 64-byte header prepended to it. Before this header is
prepended to the skb, we need to save the skb "wire" length in
GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can
be done in __bcmgenet_tx_reclaim().
3. skb->len covers the entire length of skb, whether it is linear or
fragmented. Thus, when we clean the fragments, do not increase
transmitted bytes.

macb_interrupt() should not use macb_writel(bp, ISR, <value>) but only
queue_writel(queue, ISR, <value>).
There is one IRQ and one set of {ISR, IER, IDR, IMR} [1] registers per
queue on gem hardware, though only queue0 is actually used for now to
receive frames: other queues can already be used to transmit frames.
The queue_readl() and queue_writel() helper macros are designed to access
the relevant IRQ registers.

The hilink status reg in HNS V2 is different from HNS v1. In HNS V2, It
distinguishes differnt lane status according to the bit-field of the reg.
As is shown below:
[0:0] ---> lane0
[1:1] ---> lane1
...
But the current driver reads the reg to get the hilink status ONLY
concidering HNS V1 situation. Here is a patch to support both of them.

- Netdevice brought down and freed

- Packet is queued again for process in network stack using netif_rx
Since the device appears to have been freed, the dereference of
skb->dev in get_rps_cpus() leads to an unhandled page fault
exception.
Fix this by holding on to device reference when queueing packets
asynchronously and releasing the reference on call back return.

Pull thermal updates from Zhang Rui:
- Fix a regression where bogus trip points on some Lenovo laptops start
to screw up thermal control after commit 81ad4276b5 ("Thermal:
initialize thermal zone device correctly").
On these Lenovo laptops, a bogus passive trip point is reported,
which is 0 degree Celsius. Without commit 81ad4276b5, thermal zone
fails to set cooling devices to proper cooling state, which is a bug.
But with commit 81ad4276b5 applied, the processors are always
throttled on these Lenovo laptops because the current temperature is
always higher than the passive trip point.
Fix things to ignore such bogus trip points. (Zhang Rui)
- Introduce Mediatek thermal driver. (Sascha Hauer)
- Introduce devm_ versions of OF thermal sensor register API. (Laxman
Dewangan)
- Changes in Kconfigs to allow compile test on UM arch. (Krzysztof

- Introduce Skylake support in intel_pch_thermal driver. (Srinivas

- Several small fixes on Rockchip, TI-SoC, Tegra, RCar, and Exynos

Currently we disable preemption in copy_to_user_page; a behaviour that
we inherited from the 32-bit arm code. This was necessary for older
cores without broadcast data cache maintenance, and ensured that cache
lines were dirtied and cleaned by the same CPU. On these systems dirty
cache line migration was not possible, so this was sufficient to
guarantee coherency.
On contemporary systems, cache coherence protocols permit (dirty) cache
lines to migrate between CPUs as a result of speculation, prefetching,
and other behaviours. To account for this, in ARMv8 data cache
maintenance operations are broadcast and affect all data caches in the
domain associated with the VA (i.e. ISH for kernel and user mappings).
In __switch_to we ensure that tasks can be safely migrated in the middle
of a maintenance sequence, using a dsb(ish) to ensure prior explicit
memory accesses are observed and cache maintenance operations are
completed before a task can be run on another CPU.
Given the above, it is not necessary to disable preemption in
copy_to_user_page. This patch removes the preempt_{disable,enable}
calls, permitting preemption.

Commit 324420bf91 ("arm64: add support for ioremap() block
mappings") added new p?d_set_huge functions which do the hard work to
generate and set a correct block entry.
These differ from open-coded huge page creation in the early page table
code by explicitly setting the P?D_TYPE_SECT bits (which are implicitly
retained by mk_sect_prot() for any valid prot), but are otherwise
identical (and cannot fail on arm64).
For simplicity and consistency, make use of these in the initial page
table creation code.

The KASLR code incorrectly expects the contents of x18 to be preserved
across a call into C code, and uses it to stash the contents of SCTLR_EL1
before enabling the MMU. If the MMU needs to be disabled again to create
the randomized kernel mapping, x18 is written back to SCTLR_EL1, which is
likely to crash the system if x18 has been clobbered by kasan_early_init()
or kaslr_early_init(). So use x22 instead, which is not in use so far in
head.S

So we need to trow away just stdout, leaving stderr to be caught by
the build tests infrastructure, so that we can see what went wrong
when the tarpkg build test fails:
$ make -C tools/perf build-test
make: Entering directory '/home/acme/git/linux/tools/perf'
- tarpkg: ./tests/perf-targz-src-pkg .
tests/make:302: recipe for target 'tarpkg' failed

PERF_VERSION = 4.5.g05f5ec
PERF_VERSION = 4.5.g05f5ec
In file included from bench/mem-memcpy-x86-64-asm.S:9:0:
bench/../../../arch/x86/lib/memcpy_64.S:5:29: fatal error: asm/cpufeatures.h: No such file or directory

So the test flow is:
1. Run: 'make -C tools/perf build-test'
2. One of its tests failed, in this case, the 'tarpkg' one
3. Look at what went wrong, by looking at the output of that test, in
tools/perf/tarpkg
Admittedly, this should be shortcircuited to showing what went wrong directly
from the 'make build-test' step, but lets first fix this tarpkg one and the
problem it spotted, which should be fixed by adding some extra file to the
tools/perf/MANIFEST so that detached tarballs continue being self contained and
build successfully.

Merge tag 'perf-core-for-mingo-20160323' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes:
User visible fixes:
- Fix documentation of :ppp modifier in 'perf list' (Andi Kleen)
- Fix silly nodes bitfield bits/bytes length assertion in 'perf bench numa' (Jakub Jelen)
- Remove redundant CPU output in libtraceevent (Steven Rostedt)
- Remove 'core_id' check in topology 'perf test' (Sukadev Bhattiprolu)
Infrastructure changes/fixes:
- Record text offset in dso to calculate objdump address, to use with
modules in addition to vDSO symbol address calculations (Wang Nan)
- Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)
- Add cpumode to the perf_sample struct, this way we don't need to pass
the union event to the machine and thread resolving routines, shortening
function signatures and allowing the future introduction of a way
to use tracepoint events instead of the unavailable HW cycles counter on
powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample,
at the end (Arnaldo Carvalho de Melo)
- Remove/unexport die() related infrastructure, that at some point will
finally be removed (Arnaldo Carvalho de Melo)
- Adopt linux/stringify.h from the kernel sources, not to touch this
kernel header from tools/ (Arnaldo Carvalho de Melo)
- Stop using strbuf for things we can instead trivially use libc's asprintf()
(Arnaldo Carvalho de Melo)
- Ditch tools/lib/util/abspath.c, its only exported function was used at just
one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)
- Use strerror_r() in the llvm infrastructure, tread safe, its what is used
elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)
Cleanups:
- Removed misplaced or needless __maybe_unused/export (Arnaldo Carvalho de Melo)
