Hi folks!
I'd wish ntp_loopfilter.c would compile without problems. The mess is (I had
fixed it about 15 years ago (keyword "PPSkit")) that Linux uses ADJ_* flags to
do traditional adjtime() things, as well as NTP kernel-related things (That's
why the Linux syscall is named adjtimex()).

This patch adds the needed spi node for rk3036 dts.
We have to use the 4 bus emmc to work if someone want to support
the spi devices, since the pins are re-used by emmc data[5-8] and spi.
In some caseswe need to support the spi devices, that will waste the
emmc performance.

In some conditions(such as umount fs failed),origin path or origin bdev or both
of the two is same
as cow's.If this happens, origin dev will be freed when get cow dev in function
"dm_get_device" ,
then "s->origin->dev" which used by "dm_exception_store_create" will be a NULL
pointer.

Rework to introduce spi_flash_read_message struct.

ti-qspi controller provides mmap port to read data from SPI flashes.
mmap port is enabled in QSPI_SPI_SWITCH_REG. ctrl module register may
also need to be accessed for some SoCs. The QSPI_SPI_SETUP_REGx needs to
be populated with flash specific information like read opcode, read

In addition to providing direct access to SPI bus, some spi controller
hardwares (like ti-qspi) provide special port (like memory mapped port)
that are optimized to improve SPI flash read performance.
This means the controller can automatically send the SPI signals

As late as Friday, I was planning on talking about how nice it is to
see this new trend of tiny rc2 releases, because there really hadn't
been very many pull requests at all.
But it turns out the pull requests were just heavily skewed to the end
of the week, and 4.5-rc2 isn't particularly small af

But sometimes the users might want to tell the hardware they don't

After removing __acct_update_integrals from the profile,
native_sched_clock remains as the top CPU user. This can be
reduced by only calling account_{user,sys,guest,idle}_time
once per jiffy for long running tasks on nohz_full CPUs.
This will reduce timing accuracy on nohz_ful
From: Rik van Riel
It looks like all the call paths that lead to __acct_update_integrals
already have irqs disabled, and __acct_update_integrals does not need
to disable irqs itself.
This is very convenient since about half the CPU time left in this
function was spent in local_irq_save alone.
P
(v3: address comments raised by Frederic)
Running with nohz_full introduces a fair amount of overhead.
Specifically, various things that are usually done from the
timer interrupt are now done at syscall, irq, and guest
entry and exit times.
However, some of the code that is called every single ti
From: Rik van Riel
When running a microbenchmark calling an invalid syscall number
in a loop, on a nohz_full CPU, we spend a full 9% of our CPU
time in __acct_update_integrals.
This function converts cputime_t to jiffies, to a timeval, only to
convert the timeval back to microseconds before disc
From: Rik van Riel
Change the indentation in __acct_update_integrals to make the function
a little easier to read.

Iterating code of /proc/kallsyms calls module_get_kallsym() which grabs
and drops module_mutex internally and returns "struct module *",
module is removed, aforementioned "struct module *" is used in non-trivial
way.
So, grab module_mutex for entire operation like /proc/modules does.
