tools/vm: add .gitignore to ignore built binaries

2013-02-05T09:38:46Z

There is no .gitignore in tools/vm, so 'git status' always show built binaries. To ignore this, add .gitignore. Signed-off-by: Joonsoo Kim Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Pull arm64 fixes from Catalin Marinas: - ELF coredump fix (more registers dumped than what user space expects) - SUBARCH name generation (s/aarch64/arm64/) * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64: arm64: makefile: fix uname munging when setting ARCH on native machine arm64: elf: fix core dumping to match what glibc expects

arm64: makefile: fix uname munging when setting ARCH on native machine

2013-01-22T17:51:00Z

By popular demand, arch/aarch64 is now known as arch/arm64. However, uname -m (and indeed the GNU triplet) still use aarch64 as the machine string. This patch fixes native builds of both the kernel and perf tools by updating the relevant Makefiles to munge the output of uname -m and set the ARCH variable appropriately.

tools/testing/selftests/kcmp/kcmp_test.c: print reason for failure in kcmp_test

2012-12-18T01:15:27Z

I was curious why sys_kcmp wasn't working, which led me to the testcase. It turned out I hadn't enabled CHECKPOINT_RESTORE in the kernel I was testing. Add a decoding of errno to the testcase to make that obvious. Signed-off-by: Dave Jones Acked-by: Cyrill Gorcunov Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
