this extension it adds SEI(SError Interrupt) notification

Similarly to CFQ, BFQ has its write-throttling heuristics, and it
is better not to combine them with further write-throttling

Hi!

I have no idea how to reproduce so bisecting is pretty much pointless. Any

These patch implements clocksource and clockevent by using only one hardware

It also limits usage of clocksource to 32 bits timers because 16 bits ones

Since 16 bits timers become us

This patch also forbids to use 16 bits timers because they are

At the moment, the in-kernel emulated ITS is not properly reset.
On guest restart/reset some registers keep their old values and
internal structures like device, ITE, collection lists are not emptied.

Commit 0a1eb2d474ed ("fs/proc: Stop reporting eip and esp in

racey and dangerous for executing tasks. The comment adds:
As far as I know, there are no use programs that make any
material use of these fields, so just get rid of them.

The basic concept of your proposal may work, and since it will avoid such

You are adding over 600 lines in this patch. It desearves a more forthcoming
commit message.

What functionality does it provide?
What other subsystems are involved?

Use kcalloc instead of kzalloc to check for an overflow before
multiplication. Done using the following semantic patch by
coccinelle.

There are two types of memory reservations firmware can ask the kernel
to make in the device tree: static and dynamic.
See Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt

POWER9 systems) you would get this s

Add jump targets so that a bit of exception handling can be better reused
at the end of this function.
