Bug Description
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:
* kvm: mmu: Don't read PDPTEs when paging is not enabled
* MIPS: BCM63XX: fix switch core reset on BCM6368
* powerpc/Makefile: Use cflags-y/aflags-y for setting endian options
* powerpc: Fix compiling a BE kernel with a powerpc64le toolchain
* powerpc/boot: Request no dynamic linker for boot wrapper
* x86/speculation
* Linux 4.4.202
* UBUNTU: upstream stable to v4.4.202
4.4.202 upstream stable release
from git://git.
