      In that case nor __NR_seccomp_*_32 symbols will be defined in
<asm/unistd.h> so the attempt to use it in kernel.seccomp.c will fail
with:

  __NR_seccomp_read_32, __NR_seccomp_write_32, __NR_seccomp_exit_32, __NR_seccomp_sigreturn_32,

Solved by changing the compat ABIs in kconfig to select MIPS32_COMPAT
directly.  This also means the user no longer has to select MIPS32_COMPAT
before being able to see the ABI options.

      MIPS: DMA: Add cma support · f4649382
      由 Zubair Lutfullah Kakakhel 提交于 
      Adds cma support to the MIPS architecture.

cma uses memblock. However, mips uses bootmem.
bootmem is informed about any regions reserved by memblock

dma api is modified to use cma reserved memory regions when available

Tested using cma_test. cma_test is a simple driver that assigns blocks
of memory from cma reserved sections.

      Move the SEAD-3 device-tree to arch/mips/boot/dts/ and update the
Makefiles accordingly.  Since SEAD-3 requires the device-tree to be
built into the kernel, select BUILTIN_DTB when building for SEAD-3.

      MIPS: Create common infrastructure for building built-in device-trees · 7fafb068
      由 Andrew Bresticker 提交于 
      In preparation for moving the device-trees to a common location,
introduce the config option BUILTIN_DTB, which can be selected by
platforms that use a device-tree built into the kernel image, and
create a Makefile to build the device-trees in arch/mips/boot/dts/.

      kexec: load and relocate purgatory at kernel load time · 12db5562
      由 Vivek Goyal 提交于 
      Load purgatory code in RAM and relocate it based on the location.
Relocation code has been inspired by module relocation code and purgatory
relocation code in kexec-tools.

Also compute the checksums of loaded kexec segments and store them in
purgatory.

Arch independent code provides this functionality so that arch dependent
bootloaders can make use of it.

Helper functions are provided to get/set symbol values in purgatory which
are used by bootloaders later to set things like stack and entry point of
second kernel etc.
