Currently this is only set/unset by hist triggers that make use of a
-$common_timestamp. As such, there's no reason to make this writeable

Add support for a timestamp event field. This is actually a 'pseudo-'
event field in that it behaves like it's part of the event record, but
is really part of the corresponding ring buffer event.
To make use of the timestamp field, users can specify
-"$common_timestamp" as a field name for any histogram. Note that this
+"common_timestamp" as a field name for any histogram. Note that this
doesn't make much sense on its own either as either a key or value,
but needs to be supported even so, since follow-on patches will add
-support for making use of this field in time deltas. The '$' is used
-as a prefix on the variable name to indicate that it's not a bona fide
-event field - so you won't find it in the event description - but
-rather it's a synthetic field that can be used like a real field).

Note that the use of this field requires the ring buffer be put into
'absolute timestamp' mode, which saves the complete timestamp for each
event rather than an offset. This mode will be enabled if and only if

this:

A common key to use in a histogram is the cpuid - add a new cpu
-'synthetic' field for that purpose. This field is named cpu rather
-than $cpu or $common_cpu because 'cpu' already exists as a special
-filter field and it makes more sense to match that rather than add
-another name for the same thing.

RT is not too happy about the shared timer interrupt in AT91
devices. Default to tclib timer for RT.

The arm boot_lock is used by the secondary processor startup code. The locking
task is the idle thread, which has idle->sched_class == &idle_sched_class.

+Subject: [PATCH] arm*: disable NEON in kernel mode
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.6-rt7.tar.xz
+
+NEON in kernel mode is used by the crypto algorithms and raid6 code.
+While the raid6 code looks okay, the crypto algorithms do not: NEON
+is enabled on first invocation and may allocate/free/map memory before
+the NEON mode is disabled again.
+This needs to be changed until it can be enabled.
+On ARM NEON in kernel mode can be simply disabled. on ARM64 it needs to
+stay on due to possible EFI callbacks so here I disable each algorithm.

there is a might sleep splat because get_cpu() disables preemption and

+Those crypto drivers use SSE/AVX/… for their crypto work and in order to
+do so in kernel they need to enable the "FPU" in kernel mode which
+disables preemption.
+There are two problems with the way they are used:
+- the while loop which processes X bytes may create latency spikes and
+ should be avoided or limited.
+- the cipher-walk-next part may allocate/free memory and may use
+ kmap_atomic().
+
+The whole kernel_fpu_begin()/end() processing isn't probably that cheap.
+It most likely makes sense to process as much of those as possible in one
+go. The new *_fpu_sched_rt() schedules only if a RT task is pending.
+
+Probably we should measure the performance those ciphers in pure SW
+mode and with this optimisations to see if it makes sense to keep them
+for RT.
+
+This kernel_fpu_resched() makes the code more preemptible which might hurt
+performance.
+

+Subject: [PATCH] crypto: mcryptd: protect the per-CPU queue with a lock
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.6-rt7.tar.xz
+
+mcryptd_enqueue_request() grabs the per-CPU queue struct and protects
+access to it with disabled preemption. Then it schedules a worker on the
+same CPU. The worker in mcryptd_queue_worker() guards access to the same
+per-CPU variable with disabled preemption.
+
+If we take CPU-hotplug into account then it is possible that between
+queue_work_on() and the actual invocation of the worker the CPU goes
+down and the worker will be scheduled on _another_ CPU. And here the
+preempt_disable() protection does not work anymore. The easiest thing is
+to add a spin_lock() to guard access to the list.
+
+Another detail: mcryptd_queue_worker() is not processing more than
+MCRYPTD_BATCH invocation in a row. If there are still items left, then
+it will invoke queue_work() to proceed with more later. *I* would
+suggest to simply drop that check because it does not use a system
+workqueue and the workqueue is already marked as "CPU_INTENSIVE". And if
+preemption is required then the scheduler should do it.
+However if queue_work() is used then to work item is marked as CPU
+unbound. That means it will try to run on the local CPU but it may run
+on another CPU as well. Especially with CONFIG_DEBUG_WQ_FORCE_RR_CPU=y.
+Again, the preempt_disable() won't work here but lock which was
+introduced will help.
+In order to keep work-item on the local CPU (and avoid RR) I changed it
+to queue_work_on().

+
+The code has an ifdef and uses two functions to either init the bare
+spinlock or init it and set a lock-class. It is possible to do the same
+thing without an ifdef.
+With this patch (in debug case) we first use the "default" lock class
+which is later overwritten to the supplied one. Without lockdep the set
+name/class function vanishes.

+if the timer is enqueud on CPUX and we run on CPUY then we have to
+cpu_base bits of the correct CPU. Not sure if this accounts for all the
+pieces but it might be okay with the check we have in
+hrtimer_check_target() (that we have nothing to do but just wait).

We can't have hrtimers callbacks running in hardirq context on RT. Therefore
the timers are deferred to the softirq context by default.

+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.6-rt7.tar.xz
+
+kbuild bot reported against an intermediate RT patch that the build
+fails with:
+
+> In file included from include/linux/completion.h:12:0,
+> from include/linux/rcupdate_wait.h:10,
+> from kernel/rcu/srcutiny.c:27:

+> if (___wait_is_interruptible(state) && __int) { \
+
+That error vanishes a few patches later (in the RT queue) because wait.h
+is then pulled in by other means. It does not seem to surface on !RT.
+I think that swait should include a header file for a function/macro
+(___wait_is_interruptible()) it is using.

+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.14/older/patches-4.14.6-rt7.tar.xz
+
+Commit 3840ed9548f7 ("tty: goldfish: Implement support for kernel
+'earlycon' parameter") breaks an allmodconfig config on x86:
+| LD vmlinux.o
+| MODPOST vmlinux.o
+|drivers/tty/serial/earlycon.o: In function `parse_options':
+|drivers/tty/serial/earlycon.c:97: undefined reference to `uart_parse_earlycon'
+|Makefile:1005: recipe for target 'vmlinux' failed
+
+earlycon.c::parse_options() invokes uart_parse_earlycon() from serial_core.c
+which is compiled=m because GOLDFISH_TTY itself (and most others) are =m.
+To avoid that, I'm adding the _CONSOLE config option which is selected if the
+GOLDFISH module itself is =y since it doesn't need the early bits for the =m
+case (other drivers do the same dance).
+The alternative would be to move uart_parse_earlycon() from
+serial_core.c to earlycon.c (we don't have that many users of that
+function).

CPU bringup calls into the random pool to initialize the stack
canary. During boot that works nicely even on RT as the might sleep

rwlock.h should not be included directly. Instead linux/splinlock.h
should be included. One thing it does is to break the RT build.
