Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.

The code introduced by commit 0c8893c9095d ("clockevents: Add a
clkevt-of mechanism like clksrc-of") refer to __clkevt_of_table
what doesn't exist in the vmlinux. As a result kernel build
failed with error: "clkevt-probe.c:63: undefined reference to
`__clkevt_of_table’"

This reverts commit 7b9f1d16e6d1 ("clocksource/drivers/tcb_clksrc: Use
32 bit tcb as sched_clock"). In the current state, the kernel warns
against a late registration of the new sched_clock, the printk clock
resets after only a few minutes, and it seems that scheduling can be
affected as well.

commit 93825f2ec736 converted NSEC_PER_SEC to TICK_NSEC because the author
confused NSEC_PER_JIFFY with NSEC_PER_SEC.
As a result, the calculation of refined jiffies got broken, triggering
lockups.
Fixes: 93825f2ec736 ("jiffies: Reuse TICK_NSEC instead of NSEC_PER_JIFFY")

timerfd_create() and do_timerfd_settime() evaluate capable(CAP_WAKE_ALARM)
unconditionally although CAP_WAKE_ALARM is only required for
CLOCK_REALTIME_ALARM and CLOCK_BOOTTIME_ALARM.
This can cause extraneous audit messages when using a LSM such as SELinux,
incorrectly causes PF_SUPERPRIV to be set even when no privilege was
exercised, and is inefficient.
Flip the order of the tests in both functions so that we only call
capable() if the capability is truly required for the operation.

1) Don't save TIPC header values before the header has been validated,
from Jon Paul Maloy.
2) Fix memory leak in RDS, from Zhu Yanjun.
3) We miss to initialize the UID in the flow key in some paths, from
Julian Anastasov.
4) Fix latent TOS masking bug in the routing cache removal from years

fix from Xin Long.
6) Missing module ref count drop in packet scheduler actions, from
Roman Mashak.
7) Fix RCU annotations in rht_bucket_nested, from Herbert Xu.
8) Fix use after free which happens because L2TP's ipv4 support returns
non-zero values from it's backlog_rcv function which ipv4 interprets
as protocol values. Fix from Paul Hüber.

The object palm_bk3710_port_info of type ide_port_info is never
referenced anywhere after initialization by palm_bk3710_probe. It is
also passed as a parameter to ide_host_add which is called from the init
function but this call doesn't store the object reference anywhere, and
it only dereferences the values of the fields. Therefore add __initdata
to its declaration.

====================
qed: Bug fixes
Patch #1 addresses a day-one race which is dependent on the number of Vfs
[I.e., more child VFs from a single PF make it more probable].
Patch #2 corrects a race that got introduced in the last set of fixes for
qed, one that would happen each time PF transitions to UP state.
I've built & tested those against current net-next.
Please consider applying the series there.

This reverts commit b2ae75052a8c1611b2030fa49ba1c6b6439fa04f.
The inverse logic is intentional, and this change even breaks
booting on some systems.

Pull ktest updates from Steven Rostedt:
"These are various fixes that I have made and never got around to
pushing. I've been asked to get the upstream repo back up-to-date"
* tag 'ktest-v4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest:
ktest: Add variable run_command_status to save status of commands executed
ktest.pl: Powercycle the box on reboot if no connection can be made
ktest: Add timeout to ssh command
ktest: Fix child exit code processing
ktest: Have POST_TEST run after the test has totally completed
Looks like I also missed the build config that includes
CONFIG_HIGHMEM64G && CONFIG_PARAVIRT to export the native_pud_clear()
dummy function.
