Linus Torvalds e5a32b5b21 Here are the main MIPS changes for 4.19.
An overview of the general architecture changes:
 
   - Massive DMA ops refactoring from Christoph Hellwig (huzzah for
     deleting crufty code!).
 
   - We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes & corresponding
     regsets to expose DSP ASE & floating point mode state respectively,
     both for live debugging & core dumps.
 
   - We better optimize our code by hard-coding cpu_has_* macros at
     compile time where their values are known due to the ISA revision
     that the kernel build is targeting.
 
   - The EJTAG exception handler now better handles SMP systems, where it
     was previously possible for CPUs to clobber a register value saved
     by another CPU.
 
   - Our implementation of memset() gained a couple of fixes for MIPSr6
     systems to return correct values in some cases where stores fault.
 
   - We now implement ioremap_wc() using the uncached-accelerated cache
     coherency attribute where supported, which is detected during boot,
     and fall back to plain uncached access where necessary. The
     MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
     ioremap_cacheable_cow() are removed.
 
   - The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
     systems by reworking the way we ensure remote CPUs that may be
     running threads within the affected process switch mode.
 
   - Systems using the MIPS Coherence Manager will now set the
     MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
     maintenance overhead when flushing the icache.
 
   - A few fixes were made for building with clang/LLVM, which
     now sucessfully builds kernels for many of our platforms.
 
   - Miscellaneous cleanups all over.
 
 And some platform-specific changes:
 
   - ar7 gained stubs for a few clock API functions to fix build failures
     for some drivers.
 
   - ath79 gained support for a few new SoCs, a few fixes & better
     gpio-keys support.
 
   - Ci20 now exposes its SPI bus using the spi-gpio driver.
 
   - The generic platform can now auto-detect a suitable value for
     PHYS_OFFSET based upon the memory map described by the device tree,
     allowing us to avoid wasting memory on page book-keeping for systems
     where RAM starts at a non-zero physical address.
 
   - Ingenic systems using the jz4740 platform code now link their
     vmlinuz higher to allow for kernels of a realistic size.
 
   - Loongson32 now builds the kernel targeting MIPSr1 rather than MIPSr2
     to avoid CPU errata.
 
   - Loongson64 gains a couple of fixes, a workaround for a write
     buffering issue & support for the Loongson 3A R3.1 CPU.
 
   - Malta now uses the piix4-poweroff driver to handle powering down.
 
   - Microsemi Ocelot gained support for its SPI bus & NOR flash, its
     second MDIO bus and can now be supported by a FIT/.itb image.
 
   - Octeon saw a bunch of header cleanups which remove a lot of
     duplicate or unused code.
