-# Montgomery squaring-n-multiplication module for SPARC T4.
-#
-# The module consists of three parts:
-#
-# 1) collection of "single-op" subroutines that perform single
-# operation, Montgomery squaring or multiplication, on 512-,
-# 1024-, 1536- and 2048-bit operands;
-# 2) collection of "multi-op" subroutines that perform 5 squaring and
-# 1 multiplication operations on operands of above lengths;
-# 3) fall-back and helper VIS3 subroutines.
-#
-# RSA sign is dominated by multi-op subroutine, while RSA verify and
-# DSA - by single-op. Special note about 4096-bit RSA verify result.
-# Operands are too long for dedicated hardware and it's handled by
-# VIS3 code, which is why you don't see any improvement. It's surely
-# possible to improve it [by deploying 'mpmul' instruction], maybe in
-# the future...
-#
-# Performance improvement.

-# 32-bit code is prone to performance degradation as interrupt rate
-# dispatched to CPU executing the code grows. This is because in
-# standard process of handling interrupt in 32-bit process context
-# upper halves of most integer registers used as input or output are
-# zeroed. This renders result invalid, and operation has to be re-run.
-# If CPU is "bothered" with timer interrupts only, the penalty is
-# hardly measurable. But in order to mitigate this problem for higher
-# interrupt rates contemporary Linux kernel recognizes biased stack
-# even in 32-bit process context and preserves full register contents.
-# See http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=517ffce4e1a03aea979fe3a18a3dd1761a24fafb
