Nope, good question.  That works and should be preferred.

Please use the new patch below.

From: Randy Dunlap <rdunlap@...radead.org>

Add <linux/types.h> to fix build errors.
Both ctop.h and <soc/nps/common.h> use u32 types and cause many
errors.

Examples:
../include/soc/nps/common.h:71:4: error: unknown type name 'u32'
    u32 __reserved:20, cluster:4, core:4, thread:4;
../include/soc/nps/common.h:76:3: error: unknown type name 'u32'
   u32 value;
../include/soc/nps/common.h:124:4: error: unknown type name 'u32'
    u32 base:8, cl_x:4, cl_y:4,
../include/soc/nps/common.h:127:3: error: unknown type name 'u32'
   u32 value;

../arch/arc/plat-eznps/include/plat/ctop.h:83:4: error: unknown type name 'u32'
    u32 gen:1, gdis:1, clk_gate_dis:1, asb:1,
../arch/arc/plat-eznps/include/plat/ctop.h:86:3: error: unknown type name 'u32'
   u32 value;
../arch/arc/plat-eznps/include/plat/ctop.h:93:4: error: unknown type name 'u32'
    u32 csa:22, dmsid:6, __reserved:3, cs:1;
../arch/arc/plat-eznps/include/plat/ctop.h:95:3: error: unknown type name 'u32'
   u32 value;
