I'm not so sure we should gloat yet - the verdict may be out - I saw a reference to RedHat related to POWER.

And I don't think the 390 chip is a POWER chip, is it? I could easily be wrong there.

Hope we ARE safe, of course!

IBM R0075 :)

While Intel systems are the ones known to have the defect, they may not be
the only ones affected. *Some platforms, such as SPARC and IBM's S390,
are immune to the problem*, as their processor memory management doesn't
need the split address space and shared kernel page tables; operating
systems on those platforms have always isolated their kernel page tables
from user mode ones.

Take that, Wintel Weenies :)

I know should be moved to PCTECH list but the following is interesting.

I was doing some reading about the new flaw and found the following for
Linux changes ( https://lkml.org/lkml/2017/12/4/709 ).

2) Namespace

Several people including Linus requested to change the KAISER name.

We came up with a list of technically correct acronyms:

User Address Space Separation, prefix uass_
Forcefully Unmap Complete Kernel With Interrupt Trampolines,
prefix fuckwit_
but we are politically correct people so we settled for
Kernel Page Table Isolation, prefix kpti_

Linus, your call :)

According to the news, Meltdown is specific to Intel, if so, power will
be safe, but they say that Spectre does affect other microprocessors.
Only x86, or also power?
