- boot_mem_map is removed, providing a nice cleanup made possible by the
recent removal of bootmem.
- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
MIPS32 systems using cmpxchg64().
- Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
Frascino.
- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.
- Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
- pte_special() is now supported for some configurations, allowing among
other things generic fast GUP to be used.
- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil, mostly
enabled by the inclusion of the new TCU (timer-counter unit) drivers
he's spent a very patient year or so working on. Plus some fixes for
X1000 SoCs from Zhou Yanjie.
- Netgear R6200 v1 systems are now supported by the bcm47xx platform.
- DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.
