+#### So called "highgprs" target for z/Architecture CPUs
+# "Highgprs" is kernel feature first implemented in Linux 2.6.32, see
+# /proc/cpuinfo. The idea is to preserve most significant bits of
+# general purpose registers not only upon 32-bit process context
+# switch, but even on asynchronous signal delivery to such process.
+# This makes it possible to deploy 64-bit instructions even in legacy
+# application context and achieve better [or should we say adequate]
+# performance. The build is binary compatible with linux-generic32,
+# and the idea is to be able to install the resulting libcrypto.so
+# alongside generic one, e.g. as /lib/highgprs/libcrypto.so.x.y, for
+# ldconfig and run-time linker to autodiscover. Unfortunately it
+# doesn't work just yet, because of couple of bugs in glibc
+# sysdep/s390/dl-procinfo.c affecting ldconfig and ld.so.1...

+# instructions and achieve "64-bit" performance even in 31-bit legacy

+# perform 2.4x and SHA512 - 13x better than code generated by gcc 4.3.
