Since we are now building on Solaris 10 and up we can remove all the legacy code in that method:

  // getisax(2), SI_ARCHITECTURE_32, and SI_ARCHITECTURE_64 are
  // supported on Solaris 10 and later.
  if (os::Solaris::supports_getisax()) {

We can also get rid of all the duplicate defines like:

#ifndef AV_SPARC_ASI_BLK_INIT
#define AV_SPARC_ASI_BLK_INIT 0x0080  /* ASI_BLK_INIT_xxx ASI */
#endif

Thank you, Vladimir, for the feedback!

Zoltan, I would suggest to keep solaris 10 support in these files. We still do backports into jdk8u which supports it.
