 +      * sysdeps/unix/sysv/linux/grantpt.c: Use <> brackets for not-cancel.h.
 +
 +      * sysdeps/unix/sysv/linux/faccessat.c (faccessat): Call __fxstatat64.
 +
+       * include/sys/epoll.h: New file.

 +      * sysdeps/x86_64/fpu/bits/mathinline.h (__signbitl): Optimize a bit.
 +      Avoid unnecessary __WORDSIZE == 64 test.
 +      (fmaxf): Use VEX format if possible.
 +      (fmax): Likewise.
 +      (fminf): Likewise.
 +      (fmin): Likewise.
 +
 +      * config.h.in: Define HAVE_SSE2AVX_SUPPORT.
 +      * math/math_private.h: Remove libc_fegetround* and
 +      libc_fesetround*.
 +      * sysdeps/i386/configure.in: Check for -msse2avx.
 +      * sysdeps/x86_64/fpu/math_private.h: Use VEX-encoded instructions
 +      also if SSE2AVX is defined.
 +      Remove libc_fegetround* and libc_fesetround*.
 +      * sysdeps/x86_64/fpu/multiarch/Makefile: Compile *-avx functions
 +      if config-cflags-sse2avx is yes.  Also add -DSSE2AVX to defines.
 +      * sysdeps/x86_64/fpu/multiarch/e_atan2.c: Use HAS_AVX again instead
 +      of HAS_YMM_USABLE.
 +      * sysdeps/x86_64/fpu/multiarch/e_exp.c: Likewise.
