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.

The "inv" (invalidate) instruction is generally less safe than "finv" (flush and invalidate), as it will drop dirty data from the cache. It turns out we have almost no need for "inv" (other than for the older 32-bit architecture in some limited cases), so convert to "finv" where possible and delete the extra "inv" infrastructure.

We already had a syscall that did some dcache flushing, but it was not used in practice. Make it MIPS compatible instead so it can do both the DCACHE and ICACHE actions. We have code that wants to be able to use the ICACHE flush mode from userspace so this change enables that. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>
