#include <sysdeps/unix/sysv/linux/arm/posix_fadvise.c>
Fix MIPS o32 posix_fadvise. The posix_fadvise consolidation broke posix_fadvise for MIPS o32, so resulting in posix/tst-posix_fadvise failing. MIPS o32 (and the other ABIs) has only the posix_fadvise64 syscall, which acts like posix_fadvise64_64 (in the o32 case, because of the alignment argument it's actually a 7-argument syscall). The generic posix_fadvise implementation presumes that if __NR_fadvise64 is defined, it's for the case where a single len argument is passed to the syscall rather than two syscall arguments in the case of a 32-bit system. The generic posix_fadvise64 works fine for this case (defining __NR_fadvise64_64 to __NR_fadvise64 as needed). ARM has a posix_fadvise.c that uses __posix_fadvise64_l64 in posix_fadvise, and that approach also works for MIPS o32, so this patch makes MIPS o32 include the ARM file. Tested for MIPS o32. * sysdeps/unix/sysv/linux/mips/mips32/posix_fadvise.c: New file. 2017-01-12 02:19:00 +00:00			`/* The o32 MIPS fadvise64 syscall behaves as fadvise64_64. The ARM`
