category: bugfix
bugzilla: NA
CVE: NA
MAP_PA32BIT was defined in uapi/asm-generic/mman.h, that was not
automatically included by mm/mmap.c when building on platforms such as
mips, 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
Fixes: e138253f2b82 ("svm: add support for allocing memory which is within 4G physical address in svm_mmap")
