+ [BZ #1006]
+ * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela):
+ Ensure relocation doesn't clobber any bits outside of the
+ immediate field for R_SPARC_TLS_LE_HIX22, R_SPARC_WDISP30,
+ R_SPARC_HI22 and R_SPARC_H44.

[BZ #2775]
* malloc/malloc.c (sYSMALLOc): Only call grow_heap if
(long) (MINSIZE + nb - old_size) is positive.

+ * tst-cond22.c: Include pthread.h instead of pthreadP.h.
+ Include stdlib.h.
+ * sysdeps/pthread/pthread_cond_wait.c (__condvar_cleanup): Only
+ increase FUTEX if increasing WAKEUP_SEQ. Fix comment typo.
