From: Grygorii Strashko <grygorii.strashko@xxxxxx> The build of "criss" arch is broken after applying new memblock API series. In file included from arch/cris/mm/init.c:13:0: include/linux/bootmem.h: In function 'memblock_virt_alloc': include/linux/bootmem.h:229:55: error: 'KSEG_C' undeclared (first use in this function) include/linux/bootmem.h:229:55: note: each undeclared identifier is reported only once for each function it appears in include/linux/bootmem.h: In function 'memblock_virt_alloc_nopanic': include/linux/bootmem.h:237:63: error: 'KSEG_C' undeclared (first use in this function) include/linux/bootmem.h: In function 'memblock_virt_alloc_node': include/linux/bootmem.h:250:27: error: 'KSEG_C' undeclared (first use in this function) include/linux/bootmem.h: In function 'memblock_virt_alloc_node_nopanic': include/linux/bootmem.h:258:28: error: 'KSEG_C' undeclared (first use in this function) In file included from mm/bootmem.c:14:0: include/linux/bootmem.h: In function 'memblock_virt_alloc': include/linux/bootmem.h:229:55: error: 'KSEG_C' undeclared (first use in this function) include/linux/bootmem.h:229:55: note: each undeclared identifier is reported only once for each function it appears in include/linux/bootmem.h: In function 'memblock_virt_alloc_nopanic': include/linux/bootmem.h:237:63: error: 'KSEG_C' undeclared (first use in this function) include/linux/bootmem.h: In function 'memblock_virt_alloc_node': include/linux/bootmem.h:250:27: error: 'KSEG_C' undeclared (first use in this function) The "cris" arch defines memory parameters in a different manner than other arch's and they are splitted between 2 headers: <asm/page.h> and <asm/mmu.h> As result, now build is failed if "bootmem.h" included before <asm/page.h> and <asm/mmu.h>. Hence, fix it by including additional header in bootmem.h.
