+Subject: ARM: ux500: do not directly dereference __iomem
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+commit 65b0e307a1a9193571db12910f382f84195a3d29 upstream.
+
+Sparse reports that calling add_device_randomness() on `uid` is a
+violation of address spaces. And indeed the next usage uses readl()
+properly, but that was left out when passing it toadd_device_
+randomness(). So instead copy the whole thing to the stack first.

+Subject: ktest.pl minconfig: Unset configs instead of just removing them
+
+From: Steven Rostedt <rostedt@goodmis.org>
+
+commit ef784eebb56425eed6e9b16e7d47e5c00dcf9c38 upstream.
+
+After a full run of a make_min_config test, I noticed there were a lot of
+CONFIGs still enabled that really should not be. Looking at them, I
+noticed they were all defined as "default y". The issue is that the test
+simple removes the config and re-runs make oldconfig, which enables it
+again because it is set to default 'y'. Instead, explicitly disable the
+config with writing "# CONFIG_FOO is not set" to the file to keep it from
+being set again.
+
+With this change, one of my box's minconfigs went from 768 configs set,
+down to 521 configs set.

+Subject: media: stv0288: use explicitly signed char
+
+From: Jason A. Donenfeld <Jason@zx2c4.com>
+
+commit 7392134428c92a4cb541bd5c8f4f5c8d2e88364d upstream.
+
+With char becoming unsigned by default, and with `char` alone being
+ambiguous and based on architecture, signed chars need to be marked
+explicitly as such. Use `s8` and `u8` types here, since that's what
+surrounding code does. This fixes:

+Subject: selftests: Use optional USERCFLAGS and USERLDFLAGS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Mickaël Salaün <mic@digikod.net>
+
+commit de3ee3f63400a23954e7c1ad1cb8c20f29ab6fe3 upstream.
+
+This change enables to extend CFLAGS and LDFLAGS from command line, e.g.
+to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static
+
+USERCFLAGS and USERLDFLAGS are documented in
+Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst
+
+This should be backported (down to 5.10) to improve previous kernel
+versions testing as well.
