Shrnutí:
	English: Intel CPU bug workaround
	Česky: Aplikovani zaplaty pro chybu v Intel CPU
Popis:
	English: A severe bug has been found in Intel CPUs. Unfortunately Intel is all we have now, so we have to apply a workaround as a kernel patch. Which, for one, will slow down performance of our systems. And as of writing this, the patch is not out for our kernel yet (or any nicely portable version for this venerable kernel); but should be soon, at least from Red Hat, if not OpenVZ team (in which case we'll change the announcements accordingly to allow for more QA before deploying). There's a lot of sources, for one of them all (and then Your Favorite Search Engine should spit out tons of other resources if you search for 'Intel PTI bug') -> https://www.reddit.com/r/sysadmin/comments/7nl8r0/intel_bug_incoming/
	Česky: Byla nalezena vazna chyba v Intelich procesorech. Bohuzel jedeme jenom na Intelu, takze budeme muset aplikovat patch do jadra, ktery nam pravdepodobne o neco uzere z CPU vykonu. Jak to pisu, tak patch pro nase jadro jeste neni; pokud neprijde od OpenVZ, naportujeme patch od Red Hatu, jakmile bude venku. V takovem pripade upravime plan rebootu, abychom meli vic casu to otestovat. Odkazu, o co jde, je hodne, kdyztak hodte 'Intel PTI bug' do Sveho Oblibeneho Vyhledavace (tm), vyplivne toho hromadu -> https://www.reddit.com/r/sysadmin/comments/7nl8r0/intel_bug_incoming/
