This remove the need to adjust prlimit output to expect 32 bits rlim_t. New architectures ideally will set __RLIM_T_MATCHES_RLIM64_T and use prlimit64 on {set,get}rlimit64. - Handle the case of possible new architectures that only define prlimit64 syscall (as per the kernel patch [1]). This new version handle 3 architecture scenarios: 1. New architectures that only define prlimit64. These are expected to define __RLIM_T_MATCHES_RLIM64_T and thus {set,get}rlimit{64} will aliased to {set,get}rlimit symbols. 2. Possible existence of prlimit64 syscall along with {get,set}{u}rlimit. In this case prlimit will be used if kernel header provide the definition and if runtime fails with ENOSYS the old {get,set}rlimit will be used. 3. Only the existance of {get,set}rlimit. In this case the syscalls will be used and adjustments will be made wheter __RLIM_T_MATCHES_RLIM64_T is defined. - Set __RLIM_T_MATCHES_RLIM64_T for all possible architectures so we can evaluate with #if and get possible -Wundef errors. - Remove ununsed arm old{get,set}rlimit implementations. [1] https://patchwork.kernel.org/patch/9390685/ -- This patch consolidates all Linux setrlimit and getrlimit on the default sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions: 1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19 and higher due a broken RLIM64_INFINITY constant. 2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB limit. I am not sure if it is required, but a RLIM_INFINITY fix [1] change its definition without adding a compat symbol. This patch does not aim to address this possible issue, it follow current symbol export. The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64) and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This code path is only used on kernel older than 2.6.36 (basically now only x86) and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once x86 moves to be on par with other architectures regarding minimum kernel supported we can get rid of using old syscalls and default path. A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as default for 64 bits ports. This allows the default implementation to avoid {get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit. Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a sanity build plus check-abi on all other supported architectures.
