This patch removes the __ASSUME_UTIMENSAT macro, now it can be unconditionally assumed to be true. This shows that the only live uses of __ASSUME_UTIMES are in utimes.c and they are only live for hppa. I intend a followup patch to make __ASSUME_UTIMES into an hppa-specific macro (not used or defined outside sysdeps/unix/sysv/linux/hppa/). Tested x86_64 that the disassembly of installed shared libraries is unchanged by this patch. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMENSAT): Remove macro. * sysdeps/unix/sysv/linux/futimes.c: Do not include <kernel-features.h>. [__NR_utimensat && !__ASSUME_UTIMENSAT] (miss_utimensat): Remove conditional variable definition. (__futimes): Update comment. (__futimes) [__ASSUME_UTIMENSAT]: Make code unconditional. (__futimes) [!__ASSUME_UTIMENSAT]: Remove conditional code.
