2018-04-16Merge branch 'mm-rst' into docs-nextJonathan Corbet72-2211/+2610
Mike Rapoport says: These patches convert files in Documentation/vm to ReST format, add an initial index and link it to the top level documentation. There are no contents changes in the documentation, except few spelling fixes. The relatively large diffstat stems from the indentation and paragraph wrapping changes. I've tried to keep the formatting as consistent as possible, but I could miss some places that needed markup and add some markup where it was not necessary. [jc: significant conflicts in vm/hmm.rst]

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Fix crashes when loading modules built with a different CONFIG_RELOCATABLE value by adding CONFIG_RELOCATABLE to vermagic. - Fix busy loops in the OPAL NVRAM driver if we get certain error conditions from firmware. - Remove tlbie trace points from KVM code that's called in real mode, because it causes crashes. - Fix checkstops caused by invalid tlbiel on Power9 Radix. - Ensure the set of CPU features we "know" are always enabled is actually the minimal set when we build with support for firmware supplied CPU features.

2018-04-14kernel/kexec_file.c: move purgatories sha256 to common codePhilipp Rudo5-4/+28
The code to verify the new kernels sha digest is applicable for all architectures. Move it to common code. One problem is the string.c implementation on x86. Currently sha256 includes x86/boot/string.h which defines memcpy and memset to be gcc builtins. By moving the sha256 implementation to common code and changing the include to linux/string.h both functions are no longer defined. Thus definitions have to be provided in x86/purgatory/string.c Link: http://lkml.kernel.org/r/20180321112751.22196-12-prudo@linux.vnet.ibm.com Signed-off-by: Philipp Rudo <prudo@linux.vnet.ibm.com> Acked-by: Dave Young <dyoung@redhat.com> Cc: AKASHI Takahiro <takahiro.akashi@linaro.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> Cc: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
