sys: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

MFC rev 198341 and 198342: o Introduce vm_sync_icache() for making the I-cache coherent with the memory or D-cache, depending on the semantics of the platform. vm_sync_icache() is basically a wrapper around pmap_sync_icache(), that translates the vm_map_t argumument to pmap_t. o Introduce pmap_sync_icache() to all PMAP implementation. For powerpc it replaces the pmap_page_executable() function, added to solve the I-cache problem in uiomove_fromphys(). o In proc_rwmem() call vm_sync_icache() when writing to a page that has execute permissions. This assures that when breakpoints are written, the I-cache will be coherent and the process will actually hit the breakpoint. o This also fixes the Book-E PMAP implementation that was missing necessary locking while trying to deal with the I-cache coherency in pmap_enter() (read: mmu_booke_enter_locked).

The key property of this change is that the I-cache is made coherent *after* writes have been done. Doing it in the PMAP layer when adding or changing a mapping means that the I-cache is made coherent *before* any writes happen. The difference is key when the I-cache prefetches.

Add support for 64-bit PowerPC CPUs operating in the 64-bit bridge mode provided, for example, on the PowerPC 970 (G5), as well as on related CPUs like the POWER3 and POWER4. This also adds support for various built-in hardware found on Apple G5 hardware (e.g. the IBM CPC925 northbridge). Reviewed by: grehan

Fix gdb issue where the i-cache was not being updated when a breakpoint was written into a user's address space. The fix is to modify uiomove_fromphys to sync the icache when an executable user-space page is written into. Alan Cox suggested that there should probably be a higher-level interface to this in the ptrace code, but agreed that this is an OK short-term solution. Files changed: pmap.h - declaration of pmap_page_executable() pmap_dispatch.c - pass through the page_executable call to the mmu object mmu_oea.c - implement the page_executable method by examining the PTE_EXEC field in the vm_page_t uio_machdep.c - in uiomove_fromphys(), if the op was a UIO_WRITE to user-space, and if the page is executable, sync the icache since this is at the least a breakpoint-write from gdb.
