elf-em.h: add EM_CSKY

2018-12-30T13:14:07+00:00

The uapi/linux/audit.h header is going to use EM_CSKY in order
to define AUDIT_ARCH_CSKY which is needed to implement
syscall_get_arch() which in turn is required to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

The value for EM_CSKY has been taken from arch/csky/include/asm/elf.h
and confirmed by binutils:include/elf/common.h

Move EM_XTENSA to uapi/linux/elf-em.h

2018-12-17T21:46:02+00:00

This should never have been defined in the arch tree to begin with,
and now uapi/linux/audit.h header is going to use EM_XTENSA
in order to define AUDIT_ARCH_XTENSA which is needed to implement
syscall_get_arch() which in turn is required to extend
the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

Move EM_RISCV into elf-em.h

2018-10-31T19:13:47+00:00

This should never have been inside our arch port to begin with, it's
just a relic from when we were maintaining out of tree patches.

License cleanup: add SPDX license identifier to uapi header files with no license

2017-11-02T10:19:54+00:00

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.

avr32: remove support for AVR32 architecture

2017-05-01T07:27:15+00:00

This patch drops support for AVR32 architecture from the Linux kernel.

The AVR32 architecture is not keeping up with the development of the
kernel, and since it shares so much of the drivers with Atmel ARM SoC,
it is starting to hinder these drivers to develop swiftly.

Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
Microchip).

Finally, the GCC toolchain is stuck at version 4.2.x, and has not
received any patches since the last release from Atmel;
4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this
toolchain is no longer able to properly link the network stack.

Haavard and I have came to the conclusion that we feel keeping AVR32 on
life support offers more obstacles for Atmel ARMs, than it gives joy to
AVR32 users. I also suspect there are very few AVR32 users left today,
if anybody at all.

bpf, elf: add official ELF machine define for eBPF

2016-07-20T19:37:39+00:00

Add the official BPF ELF e_machine value that was assigned recently [1,2]
and will be propagated to glibc, et al. LLVM is switching to it in 3.9
release.

elf-em.h: move EM_MICROBLAZE to the common header

2015-09-10T04:54:15+00:00

The linux/audit.h header uses EM_MICROBLAZE in order to define
AUDIT_ARCH_MICROBLAZE, but it's only available in the microblaze
asm headers.  Move it to the common elf-em.h header so that the
define can be used on non-microblaze systems.  Otherwise we get
build errors that EM_MICROBLAZE isn't defined when we try to use
the AUDIT_ARCH_MICROBLAZE symbol.
