Subject: [GIT PULL] nolibc changes for v6.1
Hello, Linus,
Once the merge window opens, please pull the latest nolibc changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git tags/nolibc.2022.09.30a
HEAD: 43cf168fa99992ee70ff041a61f866f56aa47f3b: selftests/nolibc: Avoid generated files being committed (2022-08-31 05:17:45 -0700)

nolibc pull request for v6.1
This pull request provides nolibc updates, most notably greatly improved
testing. These tests are located in tools/testing/selftests/nolibc. The
output of "make help" is as follows:
Supported targets under selftests/nolibc:
all call the "run" target below
help this help
sysroot create the nolibc sysroot here (uses $ARCH)
nolibc-test build the executable (uses $CC and $CROSS_COMPILE)
initramfs prepare the initramfs with nolibc-test
defconfig create a fresh new default config (uses $ARCH)
kernel (re)build the kernel with the initramfs (uses $ARCH)
run runs the kernel in QEMU after building it (uses $ARCH, $TEST)
rerun runs a previously prebuilt kernel in QEMU (uses $ARCH, $TEST)
clean clean the sysroot, initramfs, build and output files
The output file is "run.out". Test ranges may be passed using $TEST.
Currently using the following variables:
ARCH = x86
CROSS_COMPILE =
CC = gcc
OUTPUT = /home/git/linux-rcu/tools/testing/selftests/nolibc/
TEST =
QEMU_ARCH = x86_64 [determined from $ARCH]
IMAGE_NAME = bzImage [determined from $ARCH]
The output of a successful x86 "make run" is currently as follows,
with kernel build output omitted:
$ make run
71 test(s) passed.
