This patchset is prepared for the next 3.15 release for Linux/MIPS.
Loongson-3 is a multi-core MIPS family CPU, it is MIPS64R2 compatible
and has the same IMP field (0x6300) as Loongson-2. These patches make
Linux kernel support Loongson-3 CPU and Loongson-3 based computers
(including Laptop, Mini-ITX, All-In-One PC, etc.)

V1 -> V2:
1, Split the first patch to two patches, one is constant definition and
   the other is CPU probing, cache initializing, etc.
2, Remove Kconfig options in the first 9 patches and put all of them in
   the 10th patch.
3, Use "make savedefconfig" to generate the new default config file.
4, Rework serial port support to use PORT and PORT_M macros.
5, Fix some compile warnings.

V2 -> V3:
1, Improve cache flushing code (use cpu_has_coherent_cache macro and
   remove #ifdef clauses).
2, Improve platform-specific code to correctly set driver's dma_mask/
   coherent_dma_mask so no longer need workarounds for each driver (
   SATA, graphics card, sound card, etc.)
3, Use PCI quirk to provide vgabios and loongson3_read_bios() go away.
4, Improve CPU hotplug code and split the poweroff failure related code
   to another patch (this issue affect all MIPS CPU, not only Loongson).
5, Some other small fixes.

V3 -> V4:
1, Include swiotlb.h in radeon_ttm.c if SWIOTLB configured.
2, Remove "Reviewed-by" in patches which are added by mistake.
3, Sync the code to upstream.

V4 -> V5:
1, Split the drm patch to three patches.
2, Use platform-specific pincfgs to replace old alsa quirks.

V5 -> V6:
1, For better management, two non-Loongson-specific patches are sent
   independently.
2, Introduce cpu_has_coherent_cache feature and split cache flushing
   changes to a separate patch.
3, Remove PRID_IMP_LOONGSON3 and use PRID_IMP_LOONGSON2 since they are
   the same.
4, Don't define RTC_ALWAYS_BCD for Loongson-3 since BCD format can be
   checked by RTC_CONTROL at runtime.
5, Don't modify dma-default.c for Loongson since it is unnecessary.
6, Don't define SAREA_MAX since it is useless.
7, Increase the default boost of internal mic for Lemote A1004.
8, Fix a #ifdef issue in dma-coherence.h.
9, Some other small fixes.

V6 -> V7:
1, Fix boot failure when NR_CPUS is more than present cpus.
2, Fix error messages after poweroff & reboot.
3, Update the default config file.
4, Sync the code to upstream.

V7 -> V8:
1, Add WEAK_ORDERING/WEAK_REORDERING_BEYOND_LLSC for Loongson-3.
2, Fix a deadlock of cpu-hotplug.
3, Include swiotlb.h in arch-specific code to avoid driver modification.
4, Remove the patch "drm: Handle io prot correctly for MIPS" since it
   is already in upstream code.
5, Remove the patch "ALSA: HDA: Make hda sound card usable for Loongson"
   since it is already in upstream code.
6, Use LZMA compression and do some adjustment of config file to reduce
   kernel size.

V8 -> V9:
1, Fix spurious IPI interrupt.
2, remove __dev* attributes since CONFIG_HOTPLUG is going away as an option.
3, Use dev_info() to print messages in fixup-loongson3.c.
4, Update the default config file.
5, Sync the code to upstream.

V9 -> V10:
1, Rework "Introduce and use cpu_has_coherent_cache feature".
2, Handle the case that System BIOS doesn't contain a VGA BIOS.
3, Sync the code to upstream (mostly indentation adjustment).

V10 -> V11:
1, Remove normal labels and useless nops in inline assembler.
2, Sync the code to upstream (Prepared for 3.12).

V11 -> V12:
1, Delete __cpuinit usage;
2, Remove the third patch since it is contentious;
3, Sync the code to upstream (Prepared for 3.13).

V12 -> V13:
1, Rework addrspace.h and spaces.h;
2, Move the modification of Platform from patch 1 to patch 12;
3, Sync the code to upstream (the mips-for-linux-next branch, for 3.13).

V13 -> V14:
1, Avoid spurious interrupt from serial port;
2, Drop CONFIG_LOONGSON_BIGMEM and use CONFIG_SWIOTLB directly;
3, Sync the code to upstream (the mips-for-linux-next branch, for 3.14).

V14 -> V15:
1, Fix duplicate ARCH_SPARSEMEM_ENABLE in Kconfig.

V15 -> V16:
1, Fix all coding style errors and most of warnings;
2, Make dma address translation simple and elegant;
3, Fix potential bugs in swiotlb code;
4, Rename UEFI firmware interface to LEFI;
5, Remove 32-bit kernel support temporarily;
6, Some other small fixes (thanks to Aurelien Jarno).

V16 -> V17:
1, Kconfig adjustment;
2, Make some functions static;
3, Capitalize macros in smp code;
4, Make dma-swiotlb.c more simple;
5, Some other small fixes (thanks to Aurelien Jarno and Alex Smith).

V17 -> V18:
1, Fix two Loongson 2 breakages.
2, Tested and Reviewed by Alex Smith.

V18 -> V19:
1, Rewrite the commit message of the dma-swiotlb patch.
2, LEFI export the dma_mask_bits, which make it possible to support
   both 32-bit and 40-bit DMA.

V19 -> V20:
1, Rewrite inline assembly code in cpu-hotplug.
2, Remove the first patch since it has been merged.
3, Update the default config file.
4, Some other small fixes (thanks to Ralf Baechle).
