The thread info expects the struct names as they expect in asm/ptrace.h, but the header doesn't include that, it includes sys/user.h. Rename the reg structs to match that header. Rename the elf_siginfo to _elf_siginfo to avoid conflicting with the one in the sys/procfs.h. It is only used locally in one place, so we don't need to update any callers. Otherwise, drop in aarch64 support into the minidump-2-core file. BUG=chromium:334368 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1474 4c0a9323-5329-0410-9bdc-e9ce6186880e
