From 4afc51a835d3aeba11c35090f524e05c84586d27 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 30 Mar 2010 01:07:14 -0700 Subject: x86, ioapic: Simplify probe_nr_irqs_gsi. Use the global gsi_end value now that all ioapics have valid gsi numbers instead of a combination of acpi_probe_gsi and walking all of the ioapics and couting their number of entries by hand if acpi_probe_gsi gave us an answer we did not like.
