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:

hello, The compile error also occurs on the xtensa/alpha/powerpc/parisc/sparc platform. can you fix it?
Can we just use MAP_PA32BIT for ARM64 and x86 only? then we don't need to update multi platforms.
I think we need fix this issue as Zhengyuan did, withdraw my comments above.
Thanks Hanjun
