From 7085689ed135f94108e46c372015c6f5cd3372a3 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sat, 9 Sep 2006 12:36:25 -0700 Subject: [PARISC] Allow nested interrupts Our prior mode of operation didn't allow nested interrupts because it makes the interrupt code much simpler. However, nested interrupts are better for latency. This code uses the EIEM register to simulate level interrupts and thus achieve nesting.
