Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: 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". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. 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.

Recent compilers warn about accesses to arrays past the end, which is supported for pt_regs and sigcontext with the intended alias past the end of regs[] to sp, tp, and lr using TREG_SP, TREG_TP, and TREG_LR. Make the intended usage explict by providing an anonymous union of regs[56] on the one hand, and a short __regs[53] on the other followed by the sp, tp, and lr fields, so the aliasing is done explicitly and is visible to the compiler.

<asm/sigcontext.h> is used by glibc's <bits/sigcontext.h> from <signal.h>, which means that it can't clutter the namespace with random symbols or #defines. However, we use <arch/abi.h> to get a suitable type to hold a machine register. This change makes <arch/abi.h> safe to use in this kind of context if __need_int_reg_t is defined prior to including the file; in that case, it only defines a few symbols that are safe in the ISO namespace (prefixed with double underscores). <asm/sigcontext.h> then uses the __uint_reg_t type instead of the normal uint_reg_t.

Rather than just using pt_regs, it now contains the actual saved state explicitly, similar to pt_regs. By doing it this way, we provide a cleaner API for userspace (or equivalently, we avoid the need for libc to provide its own definition of sigcontext). While we're at it, move PT_FLAGS_xxx to where they are not visible from userspace. And always pass siginfo and mcontext to signal handlers, even if they claim they don't need it, since sometimes they actually try to use it anyway in practice.

This change is the core kernel support for TILEPro and TILE64 chips. No driver support (except the console driver) is included yet. This includes the relevant Linux headers in asm/; the low-level low-level "Tile architecture" headers in arch/, which are shared with the hypervisor, etc., and are build-system agnostic; and the relevant hypervisor headers in hv/.
