commit 36260d5035afd8c3efe55b4fe5161088f34ba644
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Fri Feb 5 16:36:30 2021 +0000
linux: Set default kernel_stat.h to LFS
The XSTAT_IS_XSTAT64 and STAT_IS_KERNEL_STAT flags are now set to 1 and
STATFS_IS_STATFS64 is set to __STATFS_MATCHES_STATFS64. This makes the
default ABI for newer ports to provide only LFS calls.
A copy of non-LFS support is provided to 32-bit ABIS with non-LFS
support (arm, csky, i386, m68k, nios2, s390, and sh). Is also allows
to remove the 64-bit ports, which already uses the default values.
This patch does not change the code generation.
