Folks,

I've merged the V8 series with the polishing done by Borislav into the
master branch (based on 5.7-rc2)  of the speck git repository at:

   cvs.ou.linutronix.de:linux/speck/linux

The commits are considered stable from now on. Any further tweaks need
to go on top.

The stable branches linux-5.6.y, linux-5.4.y, linux-4.19.y and
linux-4.14.y have been updated with backports. Kernels prior to 4.14 are
left as an exercise to the members of the kernel necrophilia cult as
usual.

A tarball with git bundles is attached.

The subject line of this mail is a reference to the following part of
the documentation:

  Executing RDRAND, RDSEED or EGETKEY will delay memory accesses from
  other logical processors that miss their core caches, with an impact
  similar to legacy locked cache-line-split accesses.

IOW, yet another DoS tool. Oh well...

Thanks,

        tglx
