[PATCH 00/35] treewide trivial patches converting pr_warning to pr_warn
There are ~4300 uses of pr_warn and ~250 uses of the older
pr_warning in the kernel source tree.
Make the use of pr_warn consistent across all kernel files.
This excludes all files in tools/ as there is a separate
define pr_warning for that directory tree and pr_warn is
not used in tools/.
Done with 'sed s/\bpr_warning\b/pr_warn/' and some emacsing.
Miscellanea:

[RFC PATCH 00/62] Linux as SEV-ES Guest Support
Hi,
here is the first public post of the patch-set to enable Linux to run
under SEV-ES enabled hypervisors. The code is mostly feature-complete,
but there are still a couple of bugs to fix. Nevertheless, given the
size of the patch-set, I think it is about time to ask for initial
feedback of the changes that come with it. To better understand the code
here is a quick explanation of SEV-ES first.

[PATCH v5 00/75] x86: SEV-ES Guest Support
From: Joerg Roedel <jroedel at suse.de>
Hi,
here is a rebased version of the latest SEV-ES patches. They are now
based on latest tip/master instead of upstream Linux and include the
necessary changes.
Changes to v4 are in particular:
- Moved early IDT setup code to idt.c, because the idt_descr
and the idt_table are now static
- This required to make stack protector work early (or
