-Subject: [PATCH 2/3] Kbuild: fix # escaping in .cmd files for future Make
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-[ commit 9564a8cf422d7b58f6e857e3546d346fa970191e in Linux ]
-
-I tried building using a freshly built Make (4.2.1-69-g8a731d1), but
-already the objtool build broke with
-
-orc_dump.c: In function ‘orc_dump’:
-orc_dump.c:106:2: error: ‘elf_getshnum’ is deprecated [-Werror=deprecated-declarations]
-  if (elf_getshdrnum(elf, &nr_sections)) {
-
-Turns out that with that new Make, the backslash was not removed, so cpp
-didn't see a #include directive, grep found nothing, and
--DLIBELF_USE_DEPRECATED was wrongly put in CFLAGS.
-
-Now, that new Make behaviour is documented in their NEWS file:
-
-  * WARNING: Backward-incompatibility!
-    Number signs (#) appearing inside a macro reference or function invocation
-    no longer introduce comments and should not be escaped with backslashes:
-    thus a call such as:
-      foo := $(shell echo '#')
-    is legal.  Previously the number sign needed to be escaped, for example:
-      foo := $(shell echo '\#')
-    Now this latter will resolve to "\#".  If you want to write makefiles
-    portable to both versions, assign the number sign to a variable:
-      C := \#
-      foo := $(shell echo '$C')
-    This was claimed to be fixed in 3.81, but wasn't, for some reason.
-    To detect this change search for 'nocomment' in the .FEATURES variable.
-
-This also fixes up the two make-cmd instances to replace # with $(pound)
-rather than with \#. There might very well be other places that need
-similar fixup in preparation for whatever future Make release contains
-the above change, but at least this builds an x86_64 defconfig with the
-new make.

-Subject: [PATCH] examples: make examples/ optional
-
-Most users don't need the standalone API examples. Distributions like SUSE
-do not supply libgcc for cross-compiling and we cannot do without on ARMv8
-for building examples/.
-
-Make examples selectable via symbol CONFIG_EXAMPLES. It defaults to
-yes on ARCH_QEMU to ensure that we compile the API as part of our
-continuous integration.
