2020-09-11	linux: Consolidate lxstat{64}	Adhemerval Zanella
	The LFS support is implemented on lxstat64.c, instead of lxstat.c for 64-bit architectures. The xstat.c implements the non-LFS and it is a no-op for !XSTAT_IS_XSTAT64. The generic non-LFS implementation handles two cases: 1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and nios): it issues __NR_fstat64 with AT_SYMLINK_NOFOLLOW plus handles the possible overflow off st_ino, st_size, or st_blocks. It only handles _STAT_VER_KERNEL. 2. Old KABIs with old non-LFS support (arm, i386, hppa, m68k, microblaze, s390, sh, powerpc, and sparc32). For _STAT_VER_KERNEL it issues __NR_lstat, otherwise it isseus __NR_lstat64 and convert to non-LFS stat struct and handle possible overflows on st_ino, st_size, or st_blocks. Also non-LFS mips is an outlier and it has its own implementation since _STAT_VER_LINUX requires a different conversion function (it uses the kernel_stat as the syscall argument since its exported ABI is different than the kernel one for both non-LFS and LFS implementation). The generic LFS implementation handles multiple cases: 1. XSTAT_IS_XSTAT64 being 1: 1.1. Old 64-bit kABI (ia64, powerpc64*, s390x, sparc64, x86_64): it issues __NR_lstat for _STAT_VER_KERNEL or _STAT_VER_LINUX. 1.2. Old 64-bit kABI with defines __NR_lstat64 instead of __NR_lstat (sparc64): it issues __NR_lstat for _STAT_VER_KERNEL or __NR_lstat64 and convert to struct stat64. 1.3. New kABIs which uses generic 64-bit Linux ABI (aarch64 and riscv64): it issues __NR_newfstatat with AT_SYMLINK_NOFOLLOW and only for _STAT_VER_KERNEL. 1.4. New 32-bit kABIs with only 64-bit time_t support (arc and riscv32): it issues __NR_statx and covert to struct stat64. 2. Old ABIs with XSTAT_IS_XSTAT64 being 0: 2.1. New kABIs which uses generic pre 64-bit time Linux ABI (csky and nios2): it issues __NR_fstatat64 for _STAT_VER_KERNEL. 2.2. Old kABIs with old non-LFS support (arm, i386, hppa, m68k, microblaze, s390, sh, mips32, powerpc32, and sparc32): it issues __NR_lstat64. Also, two special cases requires specific LFS implementations: 1. alpha: it requires to handle _STAT_VER_KERNEL64 to issue __NR_lstat64 and use the kernel_stat with __NR_lstat otherwise. 2. mips64: as for non-LFS implementation its ABIs differ from glibc exported one, which requires a specific conversion function to handle the kernel_stat. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x. Reviewed-by: Lukasz Majewski <lukma@denx.de>
