From 89291ef96916239c1c3a90dd39d52f9939464719 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 7 Jul 2017 14:38:37 -0700 Subject: [PATCH] chromium: musl: use off64_t instead of the internal __off64_t - only do the glibc 32-bit ABI check for mmap/mmap64 on gnu libc. musl does not support the 32-bit ABI.
