Subject: [GIT PULL] x86/microcode updates for 5.2

Hi Linus,

please pull

  git:// x86-microcode-for-linus

to receive a nice Intel microcode blob loading cleanup which gets rid
of the ugly memcpy wrappers and switches the driver to use the iov_iter
API. By Jann Horn.

In addition, the /dev/cpu/microcode interface is finally deprecated as it is
inadequate for the same reasons the late microcode loading is.


The following changes since commit 79a3aaa7b82e3106be97842dedfd8429248896e6:

  Linux 5.1-rc3 (2019-03-31 14:39:29 -0700)

are available in the Git repository at:
