++
++/* In GLIBC 2.10 HPPA switched from Linuxthreads to NPTL, and in order 
++to maintain ABI compatibility with pthread_cond_t, some care had to be
++taken.
++
++The NPTL pthread_cond_t grew in size. When HPPA switched to NPTL, we
++dropped the use of ldcw, and switched to the kernel helper routine for
++compare-and-swap.  This allowed HPPA to use the 4-word 16-byte aligned
++lock words, and alignment words to store the additional pthread_cond_t
++data. Once organized properly the new NPTL pthread_cond_t was 1 word
++smaller than the Linuxthreads version.
++
++However, we were faced with the case that users may have initialized the
++pthread_cond_t with PTHREAD_COND_INITIALIZER. In this case, the first
++four words were set to one, and must be cleared before any NPTL code
++used these words.
++
++We didn't want to use LDCW, because it continues to be a source of bugs
++when applications memset pthread_cond_t to all zeroes by accident. This
++works on all other architectures where lock words are unlocked at zero.
++Remember that because of the semantics of LDCW, a locked word is set to
++zero, and an unlocked word is set to 1.
++
++Instead we used atomic_compare_and_exchange_val_acq, but we couldn't use
++this on any of the pthread_cond_t words, otherwise it might interfere
++with the current operation of the structure. To solve this problem we
++used the left over word.
++
++If the stucture was initialized by a legacy Linuxthread
++PTHREAD_COND_INITIALIZER it contained a 1, and this indicates that the
++structure requires zeroing for NPTL. The first thread to come upon a
++pthread_cond_t with a 1 in the __initializer field, will
++compare-and-swap the value, placing a 2 there which will cause all other
++threads using the same pthread_cond_t to wait for the completion of the
++initialization. Lastly, we use a store (with memory barrier) to change
++__initializer from 2 to 0. Note that the store is strongly ordered, but
++we use the PA 1.1 compatible form which is ",ma" with zero offset.
++
++In the future, when the application is recompiled with NPTL
++PTHREAD_COND_INITIALIZER it will be a quick compare-and-swap, which
++fails because __initializer is zero, and the structure will be used as
++is correctly.  */
