[PATCH 3/6] Split sparc out of main Linux kernel-features.h.
This patch splits sparc out of the main Linux kernel-features.h. Not tested. * sysdeps/unix/sysv/linux/sparc/kernel-features.h: New file. * sysdeps/unix/sysv/linux/kernel-features.h [__sparc__] (__ASSUME_SOCKETCALL): Do not define. (__ASSUME_SET_ROBUST_LIST): Define unconditionally. (__ASSUME_FUTEX_LOCK_PI): Likewise. [__sparc__] (__ASSUME_ACCEPT4_SYSCALL): Do not define. [__sparc__] (__ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL): Likewise. (__ASSUME_REQUEUE_PI): Define unconditionally. [__LINUX_KERNEL_VERSION >= 0x020621 && __sparc__] (__ASSUME_RECVMMSG_SYSCALL): Do not define. [__sparc__] (__ASSUME_RECVMMSG_SYSCALL_WITH_SOCKETCALL): Likewise. [__LINUX_KERNEL_VERSION >= 0x030000 && __sparc__] (__ASSUME_SENDMMSG_SYSCALL): Likewise. [__sparc__] (__ASSUME_SENDMMSG_SYSCALL_WITH_SOCKETCALL): Likewise.
