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.

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.

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.
