[PATCH] math-emu: correct test for downshifting fraction in _FP_FROM_INT()
The kernel's math-emu code contains a macro _FP_FROM_INT() which is used to convert an integer to a raw normalized floating-point value. It does this basically in three steps: 1. Compute the exponent from the number of leading zero bits. 2. Downshift large fractions to put the MSB in the right position for no... 19 Jul 2010 19:04

[Patch 03/25] GRU - update gru tlb miss statistics
From: Jack Steiner <steiner(a)sgi.com> Update the GRU TLB dropin statistics. Add counts to indicate number of TLB miss interrupts and a separate count of TLB entries actually written.

[Patch 15/25] GRU - reorder interrupt processing
From: Jack Steiner <steiner(a)sgi.com> Reorder the servicing of CBR completion interrupts & TLB miss interrupts. There is a small performance gain to service TLB misses first.
