License cleanup: add SPDX license identifier to uapi header files with no license Many user space API headers are missing licensing information, which makes it hard for compliance tools to determine the correct license. By default are files without license information under the default license of the kernel, which is GPLV2. Marking them GPLV2 would exclude them from being included in non GPLV2 code, which is obviously not intended. The user space API headers fall under the syscall exception which is in the kernels COPYING file: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". otherwise syscall usage would not be possible. Update the files which contain no license information with an SPDX license identifier. The chosen identifier is 'GPL-2.0 WITH Linux-syscall-note' which is the officially assigned identifier for the Linux syscall exception. SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

powerpc: fix EDEADLOCK redefinition error in uapi/asm/errno.h commit 7de21e679e6a789f3729e8402bc440b623a28eae upstream. A few archs like powerpc have different errno.h values for macros EDEADLOCK and EDEADLK. In code including both libc and linux versions of errno.h, this can result in multiple definitions of EDEADLOCK in the include chain. Definitions to the same value (e.g. seen with mips) do not raise warnings, but on powerpc there are redefinitions changing the value, which raise warnings and errors (if using "-Werror"). Guard against these redefinitions to avoid build errors like the following, first seen cross-compiling libbpf v5.8.9 for powerpc using GCC 8.4.0 with musl 1.1.24: In file included from ../../arch/powerpc/include/uapi/asm/errno.h:5, from ../../include/linux/err.h:8, from libbpf.c:29: ../../include/uapi/asm-generic/errno.h:40: error: "EDEADLOCK" redefined [-Werror] #define EDEADLOCK EDEADLK In file included from toolchain-powerpc_8540_gcc-8.4.0_musl/include/errno.h:10, from libbpf.c:26: toolchain-powerpc_8540_gcc-8.4.0_musl/include/bits/errno.h:58: note: this is the location of the previous definition #define EDEADLOCK 58 cc1: all warnings being treated as errors Cc: Stable <stable@vger.kernel.org> Reported-by: Rosen Penev <rosenp@gmail.com> Signed-off-by: Tony Ambardar <Tony.Ambardar@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200917135437.1238787-1-Tony.Ambardar@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
