Subject: MIPS: N32: Define getdents64.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=31c984a5acabea5d8c7224dc226453022be46f33;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

MIPS: N32: Define getdents64.

As a relativly new ABI N32 should only have received the getdents64(2) but
instead it only had getdents(2).  This was noticed as a performance anomaly
in glibc.
