"old_guard" needs to be a page aligned pointer in the call to mprotect.  After doing the alignments, we
are left with integer values.  We could remove the casts in the above lines and add a cast in the call
to mprotect, but then new_guard and old_guard would become unsigned long.  So, the lines are about
the same length.

I did review the patch and found that the compare was reversed, so the call to mprotect was always
being skipped.

I submitted the revised change to the glibc list:
https://sourceware.org/ml/libc-alpha/2017-04/msg00269.html

-/* 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.  */
