MAP_PA32BIT was defined in uapi/asm-generic/mman.h, that was not automatically included by mm/mmap.c when building on mips platform, and result in following compiling error:

mm/mmap.c: In function ‘do_mmap’: mm/mmap.c:1450:14: error: ‘MAP_PA32BIT’ undeclared (first use in this function); did you mean ‘MAP_32BIT’? if (flags & MAP_PA32BIT) ^~~~~~~~~~~ MAP_32BIT mm/mmap.c:1450:14: note: each undeclared identifier is reported only once for each function it appears in make[1]: *** [scripts/Makefile.build:303: mm/mmap.o] Error 1

hello, The compile error also occurs on the xtensa/alpha/powerpc/parisc/sparc platform. can you fix it?

Thanks
