/* The fields in this structure are arranged so that they can be
* picked up two at a time with 128-bit loads.
*
* Because of flipped bit order for this CRC polynomials
* the constant for X**N is left-shifted by 1. This is because
* a 64 x 64 polynomial multiply produces a 127-bit result
* but the highest term is always aligned to bit 0 in the container.
* Pre-shifting by one fixes this, at the cost of potentially making
* the 32-bit constant no longer fit in a 32-bit container (thus the
* use of uint64_t, though this is also the size used by the carry-
* less multiply instruction.
*
* In addition, the flipped bit order and highest-term-at-least-bit
* multiply changes the constants used. The 96-bit result will be
* aligned to the high-term end of the target 128-bit container,
* not the low-term end; that is, instead of a 512-bit or 576-bit fold,
* instead it is a 480 (=512-32) or 544 (=512+64-32) bit fold.
*
* This cause additional problems in the 128-to-64-bit reduction; see the
* code for details. By storing a mask in the otherwise unused half of
* a 128-bit constant, bits can be cleared before multiplication without
* storing and reloading. Note that staying on a 128-bit datapath means
* that some data is uselessly stored and some unused data is intersected
* with an irrelevant constant.

MPSS Changes Start.
The JVM binary needs to be built and run on pre-Solaris 9
systems, but the constants needed by MPSS are only in Solaris 9
header files. They are textually replicated here to allow
building on earlier systems. Once building on Solaris 8 is
no longer a requirement, these #defines can be replaced by ordinary
system .h inclusion.
In earlier versions of the JDK and Solaris, we used ISM for large pages.
But ISM requires shared memory to achieve this and thus has many caveats.
MPSS is a fully transparent and is a cleaner way to get large pages.
Although we still require keeping ISM for backward compatiblitiy as well as
giving the opportunity to use large pages on older systems it is
recommended that MPSS be used for Solaris 9 and above.
