      MIPS: Only include mmzone.h when CONFIG_NEED_MULTIPLE_NODES=y · fc9e3f49
      Paul Burton authored
      commit 66a4059b upstream.
      
      MIPS' asm/mmzone.h includes the machine/platform mmzone.h
      unconditionally, but since commit bb53fdf3 ("MIPS: c-r4k: Add
      r4k_blast_scache_node for Loongson-3") is included by asm/rk4cache.h for
      all r4k-style configs regardless of CONFIG_NEED_MULTIPLE_NODES.
      
      This is problematic when CONFIG_NEED_MULTIPLE_NODES=n because both the
      loongson3 & ip27 mmzone.h headers unconditionally define the NODE_DATA
      preprocessor macro which is aready defined by linux/mmzone.h, resulting
      in the following build error:
      
        In file included from ./arch/mips/include/asm/mmzone.h:10,
                         from ./arch/mips/include/asm/r4kcache.h:23,
                         from arch/mips/mm/c-r4k.c:33:
        ./arch/mips/include/asm/mach-loongson64/mmzone.h:48: error: "NODE_DATA" redefined [-Werror]
         #define NODE_DATA(n)  (&__node_data[(n)]->pglist)
      
        In file included from ./include/linux/topology.h:32,
                         from ./include/linux/irq.h:19,
                         from ./include/asm-generic/hardirq.h:13,
                         from ./arch/mips/include/asm/hardirq.h:16,
                         from ./include/linux/hardirq.h:9,
                         from arch/mips/mm/c-r4k.c:11:
        ./include/linux/mmzone.h:907: note: this is the location of the previous definition
         #define NODE_DATA(nid)  (&contig_page_data)
      
      Resolve this by only including the machine mmzone.h when
      CONFIG_NEED_MULTIPLE_NODES=y, which also removes the need for the empty
      mach-generic version of the header which we delete.

      spi: bcm2835: Unbreak the build of esoteric configs · 0dacf045
      Lukas Wunner authored
      commit 29bdedfd upstream.
      
      Commit e82b0b38 ("spi: bcm2835: Fix race on DMA termination") broke
      the build with COMPILE_TEST=y on arches whose cmpxchg() requires 32-bit
      operands (xtensa, older arm ISAs).
      
      Fix by changing the dma_pending flag's type from bool to unsigned int.
